## What it is
C2concealer is a Python command line tool that generates randomized Cobalt Strike malleable C2 profiles. It builds profile blocks from randomized valid values, runs consistency checks, and validates output with Cobalt Strike's c2lint.

## Use cases
- generate randomized malleable C2 profiles for Cobalt Strike
- create varied HTTP client/server C2 variants for red team engagements
- avoid static signatures on generated C2 profiles
- quickly produce lint-validated Cobalt Strike profiles
- customize profile data ranges for unique C2 traffic

## When to choose
- you run Cobalt Strike and need randomized malleable C2 profiles
- you want multiple HTTP variants with different IOCs per beacon
- you want profiles validated with c2lint before an engagement

## When to avoid
- you don't use Cobalt Strike
- you need a fully turnkey evasion solution without customization
- your use is not authorized offensive security testing
