Detected with Windows Defender Antivirus

Aliases: No associated aliases


This malware is a modified version of the Process Hacker tool used by threat actors to tamper with security-related services and perform DLL search order hijacking and other attack techniques. 

NOTE: Previous detections under this name also applied to legitimate, unmodified versions of Process Hacker that have been used for malicious purposes. We have addressed these incorrect detections starting with security intelligence version 1.307.674.0 released December 17, 2019. Detections under this name now apply only to modified versions of Process Hacker. Microsoft, however, continues to maintain behavioral detections that can catch malicious use of the legitimate tool.

Windows Defender Antivirus automatically removes threats as they are detected. However, many infections can leave remnant files and system changes. Updating your antimalware definitions and running a full scan might help address these remnant artifacts.

You can also visit our advanced troubleshooting page or search the Microsoft virus and malware community for more help.
