Cobalt Strike gives you a post-exploitation agent and covert channels to emulate a quiet long-term embedded actor in your customer’s network. Malleable C2 lets you change your network indicators to look like different malware each time. These tools complement Cobalt Strike’s solid social engineering process, its robust collaboration capability, and unique reports designed to aid blue team training.
Cobalt Strike 4.5 is now available. This release sees new options for process injection, updates to the sleep mask and UDRL kits, evasion improvements and a command history update along with other, smaller changes.
Security Updates
Before getting into the details of the release, I just wanted to impress upon you how seriously we take product security. We dedicated a significant portion of this release to improving controls around product licensing. We are fully committed to improving the security of the product and will continue to make product security enhancements a priority in future releases.
Process Injection
Until now, Cobalt Strike’s only process injection option was the built-in fork&run technique. While this is good for stability, it limits OPSEC options. We have added two new Aggressor Script hooks (PROCESS_INJECT_SPAWN and PROCESS_INJECT_EXPLICIT) to allow you to define how the fork&run and explicit injection techniques are implemented when executing post exploitation commands. A new BOF along with an Aggressor Script function implements both of these new techniques. You will now have the option of using the built-in fork&run technique or creating your own process injection technique.
