Beware of Malware Through WhatsApp on Windows

Instead of simply receiving a photo or video, you might inadvertently download malware. This vulnerability enables cyber attackers to disguise malicious code as seemingly innocuous attachments.Impact on WhatsApp‘s Windows ApplicationWhatsApp identifies incoming attachments by their MIME type—the identifier for the file’s content. However, the app relies on the file extension when opening it. This newly discovered vulnerability exploits this inconsistency.
