Confidence:	60%

Signatures

Sigma detected: Files With System Process Name In Unsuspected Locations

Allocates memory with a write watch (potentially for evading sandboxes)

Creates a process in suspended mode (likely to inject code)

Found a high number of Window / User specific system calls (may be a loop to detect user behavior)

May sleep (evasive loops) to hinder dynamic analysis
