Sliver C2

[0x1]

Warning: Sliver is currently in alpha, you've been warned ​

Implant framework ​

Sliver is a general purpose cross-platform implant framework that supports C2 over Mutual-TLS, HTTP(S), and DNS. Implants are dynamically compiled with unique X.509 certificates signed by a per-instance certificate authority generated when you first run the binary.

The server, client, and implant all support MacOS, Windows, and Linux (and possibly every Golang compiler target but we've not tested them all).
