Sliver Basic's Workshop
Sliver is an open-source adversary emulation command-and-control (C2) framework that runs on Windows, Linux, and macOS. It is commonly referred to as a "Red Team tool", but it can be used for all types of offensive security testing. Sliver is capable of creating "implants" which support the C2 activities using Mutual TLS (mTLS), HTTP/HTTPS, DNS, and WireGuard. It is a client / server framework where multiple operators can be logged in and using the server at any one time.
