JPEG exploit could beat antivirus software

Antivirus software could be ill-prepared to protect corporate networks from the latest Windows vulnerability–innocent-looking JPEG files that contain security attacks.


According to Mikko Hypponen, director of antivirus research for F-Secure, antivirus software will strain to find JPEG malware because by default it only searches for .exe files.


“Normal antivirus software by default will not detect JPEGs,” Hypponen said. “You can set your antivirus scanner to look for JPEG, but the trouble is that you can change the file extension on a JPEG to so many things.”
