New Kraken worm evading harpoons of antivirus programs

"Researchers at Damballa Inc have uncovered evidence of a powerful new botnet they've nicknamed Kraken. The company estimates that Kraken has infected 400,000 systems, which would make it twice the size of Storm during that botnet's hayday. (The final size of Storm's botnet is disputed; Damballa estimates Storm infected up to 200,000 machines)."
