Techniques & procedures

4 distinct techniques documented for this family, organized by ATT&CK tactic.

Privilege Escalation

1 technique

T1068Exploitation for Privilege EscalationEvidence1

they also used the BYOVD (Bring Your Own Vulnerable Driver) malware to incapacitate security products... Mhyprot2DrvControl uses the BYOVD (Bring Your Own Vulnerable Driver) technique, which abuses vulnerable Windows driver files and uses the escalated privilege to perform arbitrary behaviors.

Stealth

1 technique

T1620Reflective Code LoadingEvidence1

The first feature decodes the compressed .NET PE before loading and executing it in the memory.

Discovery

1 technique

T1057Process DiscoveryEvidence1

Routine for checking the process list to terminate AV products

Other

1 technique

T1562Impair DefensesEvidence1

used the BYOVD technique to incapacitate security products installed in the system... develop a malware that shuts down multiple anti-malware products.
