Kraken problem.
Kraken, the largest botnet (collection of bots that run things automatically) was revealed by researchers. They said that in this network, a total of 400,000 computers are infected by a malware, including computers from 50 Fortune 500 companies. What is disturbing is that, only 20 percent of the computers with the different anti-virus products can detect the said malware. Kraken is said to have the ability to change its code base, and that is the reason why most anti-malware and anti-virus products cannot detect it. This bot copies itself to other machines automatically when executed by another machine (auto bots).
