Lame Stuxnet worm 'full of errors', says security consultant

http://www.theregister.co.uk/2011/01/19/stuxnet_male_decry_security_researchers/ By John Leyden The Register 19th January 2011 Far from being cyber-spy geniuses with ninja-like black-hat coding skills, the developers of Stuxnet made a number of mistakes that exposed their malware to earlier detection and meant the worm spread more widely than intended. Stuxnet, the infamous worm that infected SCADA-based computer control systems, is sometimes described as the world's first cyber-security weapon. It managed to infect facilities tied to Iran's controversial nuclear programme before re-programming control systems to spin up high-speed centrifuges and slow them down, inducing more failures than normal as a result. The malware used rootkit-style functionality to hide its presence on infected systems. In addition, Stuxnet made use of four zero-day Windows exploits as well as stolen digital certificates. All this failed to impress security consultant Tom Parker, who told the Black Hat DC conference on Tuesday that the developers of Stuxnet had made several mistakes. For one thing, the command-and-control mechanisms used by the worm were inelegant, not least because they sent commands in the clear. The worm spread widely across the net, something Parker argued was ill-suited for the presumed purpose of the worm as a mechanism for targeted computer sabotage. Lastly, the code-obfuscation techniques were lame. Parker doesn't dispute that the worm is as sophisticated as most previous analysis would suggest, or that it took considerable skills and testing to develop. "Whoever did this needed to know WinCC programming, Step 7, they needed platform process knowledge, the ability to reverse engineer a number of file formats, kernel rootkit development and exploit development," Parker said, Threatpost reports. "That's a broad set of skills.” [...]
