Thanks to CTOnews.com netizen soft media user 1520111 for the clue delivery! CTOnews.com October 19 news, popular compressed file management software WinRAR recently discovered a serious security vulnerability, the vulnerability number CVE-2023-38831. This vulnerability allows hackers to execute arbitrary code on users 'computers using malicious files, compromising users' data and privacy security.

According to Google's Threat Analysis Group (TAG), this vulnerability has been exploited by multiple cybercrime organizations. Cybercrime organizations began exploiting the vulnerability in early 2023, when defenders were unaware of it. Currently, WinRAR has released a fix patch, but there are still many users who have not updated in time and are still in danger.

The attacker's modus operandi is to place a seemingly harmless file (such as a PNG image) in a ZIP archive and open it via WinRAR. WinRAR executes malicious code in compressed packages due to an error in Windows handling file names with spaces.

Google's update notes state,"WinRAR before version 6.23 executes 'poc.png_/poc.png_.cmd' when users double-click a file named 'poc.png_'(underlined for spaces) on WinRAR's interface. "
