The Stuxnet worm is a "groundbreaking" piece of
malware so devious in its use of unpatched vulnerabilities, so
sophisticated in its multipronged approach, that the security
researchers who tore it apart believe it may be the work of state-backed
"It's amazing, really, the resources that went
into this worm," said Liam O Murchu, manager of operations with
Symantec's security response team.

said Roel Schouwenberg, a senior antivirus researcher at Kaspersky Lab.
In comparison, other notable attacks, like the one dubbed Aurora that
hacked Google's network and those of dozens of other major companies,
