Signatures

Multi AV Scanner detection for submitted file
Yara detected AntiVM3
Yara detected UAC Bypass using CMSTP
.NET source code references suspicious native API functions
Found potential dummy code loops (likely to delay analysis)
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Abnormal high CPU Usage
Allocates memory with a write watch (potentially for evading sandboxes)
Binary contains a suspicious time stamp
Detected potential crypto function
Enables debug privileges
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
PE file does not import any functions
Potential time zone aware malware
Program does not show much activity (idle)
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Uses code obfuscation techniques (call, push, ret)
