According to Techworld, Finnish security firm F-Secure has cracked a code used by the Sober worm. This means that potentially the company can block the worm from receiving updates. Sober has mutated more than 20 times since October 2003, when the first variant was picked up.
But it better act fast: Due to Sober’s ability to download new variants, it can instantly infect large numbers of machines. According to PCWorld, the latest variant is programmed to download an unknown piece of code from various Internet addresses early in January, potentially launching a barrage of digital traffic.
