Researchers are warning that the Conficker worm has been reprogrammed to strengthen its defences and boost its ability to attack more machines.
Conficker takes advantage of a vulnerability in Microsoft’s software, and has infected at least 3 million PCs and possibly as many as 12 million, making it into a huge botnet and one of the most severe computer security problems in recent years. Botnets can be used to send spam and attack other websites, but they need to be able to receive new instructions. Techworld.com – Conficker reprogrammed for new attack run
