Signatures

Yara detected Branchlock Obfuscator
AI detected suspicious sample
Exploit detected, runtime environment starts unknown processes
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
AV process strings found (often used to terminate AV products)
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to detect virtual machines (SLDT)
Contains functionality to query CPU information (cpuid)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Enables debug privileges
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Uses cacls to modify the permissions of files
Uses code obfuscation techniques (call, push, ret)
