The Stuxnet Worm
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 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. In comparison, other notable attacks, like the one dubbed Aurora that hacked Google’s network and those of dozens of other major companies, were child’s play.
EDITED TO ADD (9/22): Here’s an interesting theory:
By August, researchers had found something more disturbing: Stuxnet appeared to be able to take control of the automated factory control systems it had infected – and do whatever it was programmed to do with them. That was mischievous and dangerous.
But it gets worse. Since reverse engineering chunks of Stuxnet’s massive code, senior US cyber security experts confirm what Mr. Langner, the German researcher, told the Monitor: Stuxnet is essentially a precision, military-grade cyber missile deployed early last year to seek out and destroy one real-world target of high importance – a target still unknown.
The article speculates that the target is Iran’s Bushehr nuclear power plant, but there’s not much in the way of actual evidence to support that.
