WinRAR: Researchers at digital security firm Positive Technologies have discovered a vulnerability in the traditional file compression program WinRAR. The loophole was found in version 5.7 of the software in its free trial version, which is the most popular.
As the attack operates in a man-in-the-middle mode, not all users can be victims of WinRAR exploitation: in addition to not bypassing traditional defenses, which include security warnings from Windows itself, this scam can only be performed in full if the network domain is already compromised by the same criminals.
WinRAR has already been updated to versions that fix the vulnerability and is currently in release 6.02. Check the version of your application in the item Help > About WinRAR in the program window and, preferably, download the latest one to your PC.
