Signatures

Multi AV Scanner detection for submitted file
Yara detected GuLoader
Contain functionality to detect virtual machines
Contains functionality to detect hardware virtualization (CPUID execution measurement)
Contains functionality to hide a thread from the debugger
Detected RDTSC dummy instruction sequence (likely for instruction hammering)
Found potential dummy code loops (likely to delay analysis)
Hides threads from debuggers
Machine Learning detection for sample
Tries to detect Any.run
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to detect virtualization through RDTSC time measurements
Abnormal high CPU Usage
Checks if the current process is being debugged
Contains functionality for execution timing, often used to detect debuggers
