Worms spread faster, blended threats grow

Virus writers are increasingly targeting more recent security vulnerabilities in their attempts to spread malicious code. The latest bi-annual Internet Security Threat Report from Symantec found that 64 per cent of all new attacks targeted vulnerabilities less than one year old. The Blaster worm, for example, appeared only 26 days after the vulnerability it exploited was announced. Some 66 per cent of all attacks documented in the first half of 2003 exploited vulnerabilities categorised as highly severe. Symantec’s study paints a picture of a rise in more sophisticated and faster spreading worms, and the increased use by virus writers of new vectors for infection (such as P2P networks and IM applications). Symantec reports that the increasing prevalence of blended threats, which use a combination of malicious code and vulnerabilities to launch a cyber attack, remains one of the most significant security issues companies face this year. Blended threats accounted for 60 per cent of malicious code submissions in the first half of 2003, and the number of blended threats increased by 20 per cent. Full Story
