![]() ![]() One final, small update to mention is that to save you a click, the 圆4 checkbox is now checked by default on all payload generation dialogs. A new Aggressor hook ( BEACON_DLL_SIZE) allows you to specify whether to reserve 5k (the current threshold) or 100k for your custom loader. Following user feedback, we have increased the reserved size in Beacon for a larger User Defined Reflective Loader. Like the Sleep Mask kit, the User Defined Reflective Loader kit was introduced in Cobalt Strike 4.4. User Defined Reflective Loader Kit Update Secondly, we have added support to the kit for masking heap memory. Firstly, following user feedback, we have increased available space from 289 to 769 bytes. There are two changes to the sleep mask kit in this release. ![]() The Sleep Mask kit was introduced in Cobalt Strike 4.4. Max Retry Strategy Sleep Mask Kit Updates The strategy comes with a number of default values for exit and sleep thresholds but you will be able to add custom values with a new Aggressor hook ( LISTENER_MAX_RETRY_STRATEGIES). As failure count crosses a threshold, the sleep time is adjusted to a specified value. The “max retry” strategy is available for HTTP, HTTPS and DNS Beacons and it allows you to tell a Beacon to exit after a specified failure count. This release also sees the addition of a complementary strategy to the existing Host Rotation Strategy. Is that all? No! We’ve also made working with command history more Unix-like by adding support for bang (!) characters. You can choose to display all commands in the command history (“ history all”) or specify how many commands that you want to display (for example, “ history 10”). We have added a “history” command that displays your command history. Not only did we fix that, we also overhauled command history to make it much more usable. There was an outstanding issue whereby scrolling back through your command history and then running a new command would insert that command in the wrong place in the command history. Since adding the reconnect button in the 4.4 release, the new number one change request relates to issues with command history. Example: The keylogger using a custom process injection technique written by Command History You will now have the option of using the built-in fork&run technique or creating your own process injection technique. A new BOF along with an Aggressor Script function implements both of these new techniques. 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. While this is good for stability, it limits OPSEC options. ![]() Until now, Cobalt Strike’s only process injection option was the built-in fork&run technique. We are fully committed to improving the security of the product and will continue to make product security enhancements a priority in future releases. We dedicated a significant portion of this release to improving controls around product licensing. Security Updatesīefore getting into the details of the release, I just wanted to impress upon you how seriously we take product security. 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. ![]()
