Hey there, did you hear about the recent zero-day vulnerability in WinRAR? It’s a serious issue that could lead to code execution attacks on systems. Even though WinRAR has fixed the flaw, hackers are still using it to spread RomCom malware through maliciously crafted archived files.
Details of the WinRAR Zero-Day Exploitation
Security researchers at ESET uncovered a critical vulnerability in WinRAR that could potentially allow attackers to execute malicious code. This flaw, known as CVE-2025-8088, was rated as highly severe with a CVSS score of 8.4. WinRAR explained that the vulnerability could trick the software into using a specially crafted archive path instead of the user-specified path when extracting files.
It’s important to note that this vulnerability only affects WinRAR for Windows and not Unix or Android versions.
According to BleepingComputer, ESET researchers found that hackers are actively exploiting this vulnerability to distribute the RomCom backdoor through spearphishing attacks using malicious RAR files sent via email.
WinRAR has since released a patch for this vulnerability in version 7.13. It’s crucial for users to update their systems to the latest version to protect against potential risks.
Stay Vigilant and Update Your Systems
With the increasing threat of phishing attacks, it’s essential for organizations to educate their employees about the dangers of interacting with malicious files. Regular security awareness sessions can help mitigate the risks associated with cyber threats.
