Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Machine Learning detection for sample
.NET source code contains potential unpacker
Injects a PE file into a foreign processes
Machine Learning detection for dropped file
C2 URLs / IPs found in malware configuration
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Yara signature match
Antivirus or Machine Learning detection for unpacked file
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
Internet Provider seen in connection with other malware
Detected potential crypto function
IP address seen in connection with other malware
Contains long sleeps (>= 3 min)
Enables debug privileges
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
