frissi0n / gtfonow Goto Github PK

The (limited) tests are only ran on Debian, expand tests to other platforms.

Add support for environments without python, such as building with pyinstaller or similar.

Add descriptions from GTFOBins to GTFONow to help user decide which exploit to use.

Upon finding exploitable ssh-agent it asks for "sudo password" and immediately crashes. I tried running it with -a flags (same behavior) and with "--sudo_password", where it asks for the sudo password once, and once provided it prompts for it again and crashes.

Running on kali-linux over wsl2 for tests, but I could test on Arch linux (no wsl) too if needed.

❯ python gtfonow.py --sudo_password

Currently GTFONow provides the user an interactive wizard for exploiting the host. If stdin is not available, or the user just wants to instantly pop a shell without choosing options, we should provide an interactionless mode.
