Notes

Veil

  • Veil is a framework for generating Undetectable backdoors. Make that less detectable.

FatRat

Also attempts to generate Undetectable Metasploit backdoors for Windows, macOS, Linux, and Android. FatRat uses encryption to bypass most of the Antivirus. It can be configured for system exploitation, post-exploitation attacks, browser attacks, DLL attacks, FUD payloads, etc.

  • SearchSploit gives a list of payloads and backdoors for every type of target

  • File Pumper increases size of a payload to increase stealth
