Use when operating Sliver C2 implants, managing listeners, or performing post-exploitation via sessions or beacons.
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
# Sliver C2 Post-Exploitation ## Sessions vs Beacons - **Sessions**: Real-time interactive. Use for active enumeration. Higher detection risk. - **Beacons**: Async callback with interval + jitter. Use for persistence. Lower detection risk. Our MCP handles both transparently — `interact(implant_id, implant_type="beacon")` resolves async tasks automatically. Beacons check in on a set interval with jitter and queue tasks between check-ins; sessions hold a live, interactive connection. See Sliver's [Beacons vs. Sessions](https://sliver.sh/docs?name=Beacons+vs.+Sessions) docs. ## Orientation (do this first) ``` connect() # or connect(config_file="...") get_sessions() # list live sessions get_beacons() # list beacons interact(implant_id="abc-123", implant_type="session") # set active target whoami() # confirm user context pwd() / ls() # confirm position …

How to install
mdr add dreadnode/capabilities/sliver-c2@sha256:48633d516ab331ffThe line at the top of this page pins the label git:20261020.a797047, 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.
