New virus communicates by pictures | |

Antivirus companies warned on Thursday of a new virus that communicates through digital images, but security experts aren't sure how much of a threat this latest evolutionary branch of malicious code poses. Dubbed the first "JPEG infector" by security company Network Associates, the W32/Perrun virus has two parts: infected JPEG images that contain the virus's payload and a viral program that extracts the code from the images and infects other JPEGs on the system as they are opened. Because PCs have to be infected by the extractor virus before any code hidden in image files can affect them, the program is more a computer-science curiosity than a threat, said Vincent Gullotto, vice president of Network Associates' antivirus emergency response team. "We are not saying that this is a problem," Gullotto said. "We gave it a low risk, but we haven't seen anything like this before." A digital image carrying code for W32/Perrun is easy to spot, he said, because the image is corrupted by the new code. | ||
