Cobalt Strike is an insanely popular red team tool with a huge feature set. Mudge created Cobalt Strike 10 years ago as a red team command and control platform. In 2020, HelpSystems acquired Cobalt Strike. Today, it is widely used by U.S. government, companies and consulting organizations.
Cobalt Strike is an excellent tool for post-exploitation and covert operations, allowing you to emulate a quiet, long-term embedded actor in your target's network. Malleable C2 lets you change your network indicators to look like different malware each time, making it even harder for detection. These tools, combined with Cobalt Strike's robust social engineering capabilities and unique reports designed to aid blue team training, make it an invaluable tool for any penetration tester.
CVE-2022-39197 is a simple XSS vulnerability but it's possible to get RCE from this because you can define an account username in the Beacon configuration.
