Is Stuxnet the 'best' malware ever?
The Stuxnet worm is a "groundbreaking" piece of malware so devious in its use of unpatched vulnerabilities, so sophisticated in its multi-pronged approach, that the security researchers who tore it apart believe it may be the work of state-backed professionals.
"It's amazing, really, the resources that went into this worm," said Liam O Murchu, manager of operations with Symantec's security response team. "I'd call it groundbreaking," said Roel Schouwenberg, a senior antivirus researcher at Kaspersky Lab. By comparison, other notable attacks, like the one dubbed "Aurora" that hacked Google's network, and those of dozens of other major companies, was child's play.
O Murchu and Schouwenberg should know: They work for the two security companies that discovered Stuxnet exploited not just one zero-day Windows bug, but four, an unprecedented number for a single piece of malware.
