PANIX: A highly customizable Linux persistence tool
PANIX
PANIX is a highly customizable Linux persistence tool for security research, detection engineering, penetration testing, CTFs and more. It prioritizes functionality over stealth and is easily detectable. PANIX is supported on popular distributions like Debian, Ubuntu, and RHEL, and is highly customizable to fit various OS environments. PANIX will be kept up-to-date with the most common *nix persistence mechanisms observed in the wild.

PANIX offers comprehensive support across various Linux distributions.
| Distribution | Support | Tested |
|---|---|---|

Dated or custom Linux distributions may use different configurations or lack specific features, potentially causing mechanisms to fail on untested versions. If a default command fails, the --custom flag in most features allows you to customize paths/commands to suit your environment. If that doesn’t work, you can examine the script to understand and adapt it to your needs.
