2020-021- Derek Rook, redteam tactics, blue/redteam comms, and detection of testing

**If Derek told you about us at SANS, send a DM to @brakeSec or email [email protected] for an invite to our slack** OSCP/HtB/VulnHub is a game... designed to have a tester find a specific nugget of information to pivot or gain access to greater power on the system.  Far different in the 'real' world.   Privilege escalation in Windows: *as of June 2020, many of these items still work, may not work completely in the future* *even so, many of these may not work if other mitigating controls are in place*   PENTEST METHODOLOGY :  PTES -http://www.pentest-standard.org/index.php/PTES_Technical_Guidelines OSSTMM - https://www.isecom.org/OSSTMM.3.pdf   Redteam methodology: https://www.synopsys.com/glossary/what-is-red-teaming.html   https://www.fuzzysecurity.com/tutorials/16.html   https://medium.com/@Shorty420/enumerating-ad-98e0821c4c78   https://github.com/swisskyrepo/PayloadsAllTheThings/blob/master/Methodology%20and%20Resources/Windows%20-%20Privilege%20Escalation.md   Enumerate the machine Services Network connections Users Logins Domains Files Software installed (putty, git, MSO, etc) *older software may install with improper permissions* Service paths (along with users services are ran as) Windows Features (WSL, SSH, etc) Patch level (Build 1703, etc) Wifi networks and passwords (netsh wlan show profile SSID> key=clear) Powershell history Bash History (if WSL is used) Incognito tokens Stored credentials (cmdkey /list) Powershell transcripts (search text files for "Windows PowerShell transcript start")   Context for above: Understand how the users make use of the system, and how they connect to other systems, follow those paths to find lateral movement, misconfigurations, etc. Each new system or user will provide further information to loot or avenues to explore   Linux EoP: https://guif.re/linuxeop   https://blog.g0tmi1k.com/2011/08/basic-linux-privilege-escalation/   Enumeration Mostly the same as above Bash history or profile files            Writable scripts (tampering with paths or environment variables) Setuid/Setgid binaries Sticky bit directories Crontabs Email spools World writable/readable files .ssh config files (keys, active sessions) Tmux/screen sessions Application secrets (database files, web files with database connectivity, hard coded creds or keys, etc) VPN profiles GNOME keyrings- https://askubuntu.com/questions/96798/where-does-seahorse-gnome-keyring-store-its-keyrings   Ways to defend against those kinds of EoP.
