Techniques and Write-ups

Tools and Exploits

  • Iscariot Suite is a collection of tools to enhance and augment trusted open-source and commercial Blue Team/Sysadmin products, turning them into traitorware to achieve offensive security goals.
  • Havoc. This is the much anticipated C2 from @C5pider. It also supports Third Party Agents.
  • ASNMap - A Golang CLI tool for speedy reconnaissance using ASN data.
  • constellation is the first Confidential Kubernetes. Constellation shields entire Kubernetes clusters from the (cloud) infrastructure using confidential computing.
  • VirusTotalC2 Abusing VirusTotal API to host our C2 traffic, useful for bypassing blocking firewall rules if VirusTotal is in the target white list, and in case you don't have C2 infrastructure, now you have a free one.
  • AzTokenFinder is a small tool to extract JWT (or JWT like looking data) from different processes, like PowerShell, Excel, Word or others.
  • Freeze is a payload toolkit for bypassing EDRs using suspended processes, direct syscalls, and alternative execution methods.
  • ChTimeStamp - Changing the Creation time and the Last Written time of a dropped file by the timestamp of other one , like the "kernel32.dll" timestamp.
  • ADSrunner - Write a UUIDs bytes array "*" collected to the Alternate Data Stream of the current binary , then the ADS Runner will get the DATA tranfert it into a char table nice UUIDS shellcode and Run it.
  • FileLessRemoteShellcode - Run Fileless Remote Shellcode directly in memory with Module Unhooking, Module Stomping, No New Thread. This repository contains the TeamServer and the Stager.
  • DumpThatLSASS - Dumping LSASS by Unhooking MiniDumpWriteDump by getting a fresh DbgHelp.dll copy from the disk, plus functions and strings obfuscation, it contains Anti-sandbox, if you run it under unperformant Virtual Machine you need to uncomment the code related to it and recompile.
  • airstrike is a basic stage 0 implant.
  • KnownDllUnhook - Replace the .txt section of the current loaded modules from KnownDllsto bypass edrs.
