WinRAR security flaw ignores Windows Mark of the Web security warnings

WinRAR bag.

WinRAR has been a staple in the PC community for decades, offering the ability to compress data into compact files for easier transfer. With that, however, comes the occasional security concern, and today we have an example of just such a situation. Reports have begun to circulate, highlighting an issue in all but the latest edition of WinRAR that enable software to execute without the Windows Mark of the Web (MotW) security warning pop-ups.

If you aren't familiar with the MotW warnings, you might recognize them as the pop-ups that warn you against running strange software from the internet. It typically includes a blurb explaining that it's dangerous to execute applications downloaded from unfamiliar sources, and includes both an option to continue regardless or to cancel the operation entirely. This system can apparently be skipped over entirely in older versions of WinRAR, making for a greater security risk.
