Detects the creation or modification of a custom protocol handler in the Windows Registry with the name "rogue" and a specific CLSID. This activity has been observed as a persistence mechanism used by the Forest Blizzard APT group (also known as Star Blizzard or COLDRIVER). By setting a custom protocol handler, the adversary can execute arbitrary code when a specially crafted URI is accessed.
Detects the setting of a DLL that handles a custom protocol handler, specifically targeting a CLSID observed in attacks attributed to Forest Blizzard APT. This technique can be used for persistence or privilege escalation by registering a malicious DLL to be loaded when a specific protocol is invoked.
Detects the creation of specific files within the ProgramData directory that have been observed in campaigns by the Forest Blizzard APT group (also known as Star Blizzard, SEABORGIUM, Callisto Group, TA446, COLDRIVER). These files include those with names like 'prnms003.inf_', 'prnms009.inf_', '.save', 'doit.bat', 'execute.bat', 'servtask.bat', and '.dll' files containing 'wayzgoose', often found in subdirectories under common vendor names within ProgramData.
Detects the creation of JavaScript files within the Windows DriverStore directory. This activity has been observed in attacks by the Forest Blizzard APT (also known as Star Blizzard) to exploit CVE-2022-38028 in the Windows Print Spooler service. The adversary modified a JavaScript constraints file and executed it with SYSTEM-level permissions to achieve privilege escalation and credential access.
Detects the execution of specific processes and command line combinations associated with the Forest Blizzard APT group. This includes the creation and deletion of scheduled tasks using 'schtasks.exe' and PowerShell commands for file operations, as described by Microsoft.
