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
Found potential string decryption / allocating functions
