Hackers abuse Windows error reporting tool to deploy malware
2023-01-04 17:16

Hackers are abusing the Windows Problem Reporting error reporting tool for Windows to load malware into a compromised system's memory using a DLL sideloading technique.

The use of this Windows executable is to stealthy infect devices without raising any alarms on the breached system by launching the malware through a legitimate Windows executable.

WerFault is the standard Windows error reporting tool used in Windows 10 and 11, allowing the system to track and report errors related to the operating system or applications.

Windows use the tool to report an error and receive potential solution recommendations.

The malicious DLL version in the ISO contains additional code to launch the malware.

Pupy RAT is an open-source and publicly available malware written in Python that supports reflective DLL loading to evade detection, and additional modules are downloaded later.
