Better-Sliver

Welcome to Better-Sliver, a fork of the Sliver project. This fork is intended to be a community-driven effort to improve the Sliver project. The goal is to make Sliver less detectable by adding more features, changing default fingerprints, and adding more obfuscation options. This fork is not intended to be a replacement for Sliver, but rather a place to experiment with new ideas and features. If you have an idea for a feature, please open an issue or a pull request.

There are current issues with the sleepmask feature. Sleepmask is not likely to happen due to go routines

Usage

  1. Git clone this repo
  2. Run make

It's that simple!

Current Features Added

  • Stopped go-donut from trying to bypass AMSI by default
  • Broke all static shellcode signatures for current version of Sliver. The only one left is a Donut signature that can be easily bypassed.
  • Changed the default mTLS server and implant CAs for different fingerprints
  • Changed the shell command, throwing off yara detections
  • Implemented JARM randomization (This has also now been added to Sliver v1.6 in dev)
  • Added some sleepmasking to the beacons (had to remove this due to big bugs)

Sliver

Sliver is an open source cross-platform adversary emulation/red team framework, it can be used by organizations of all sizes to perform security testing. Sliver's implants support C2 over Mutual TLS (mTLS), WireGuard, HTTP(S), and DNS and are dynamically compiled with per-binary asymmetric encryption keys.

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