| Verdict: | Malicious activity |
| Threats: | Sliver is an open-source command-and-control (C2) framework that has been increasingly adopted by threat actors as an alternative to tools like Cobalt Strike. Developed by security firm Bishop Fox, Sliver was initially intended for legitimate security testing and red teaming exercises. However, its robust features and open-source nature have made it attractive to malicious actors seeking to control compromised systems. |
