Along with the payload, researchers uncovered that the compressed file also contains non-malicious MP3 files which is one of the tactics attacker used to trick victims to drop the malicious payload.

According to McAfee research, “User Access Control (UAC) is bypassed after the payload gets executed, so no alert is displayed to the user. The next time the system restarts, the malware is run.”

Also, researchers uncovered over 100 unique payloads and still it’s counting, most of the sample primarily targeting the victims in U.S.

All the WinRAR users are advised to update the current patched version,
