Another missing link in Stuxnet Reveals Earlier Infection Time

Stuxnet, the government malware believed to have been created by a dual-venture of the US and Israel, and the one used to attack the Iran nuclear enrichment facility, is now believed to have an earlier attack link. It is believed now that sometime in 2008 was when the facility may have been in progress of attacks from Stuxnet.

Iran leaders met in Kazakhstan this week to discuss with members of the UN Security Council the nuclear program. The researchers there announced a new variant of the sophisticated Stuxnet cyberweapon.

Some have noted that the US and Israel may have partnered way before doing similar activities to try to take down the nuclear enrichment program in Iran.

The new variant was designed as a different attack vector against the centrifuges for the uranium enrichment program, versus later versions released. This “new variant” was apparently released in 2007. Here we are six years later, knowing the discovery of such variant. This shows that the current versions of Stuxnet were made in 2009, which means this variant now recognized predated the original code that researchers found. Therefore, its first version may have been in 2007. That tells security experts this: Stuxnet was attacking much earlier than previously thought.

Still to make a rebuttal, Iran is awaiting and planning new cyberwarriors, which can construct cyberattacks and cyberterrorism on the US.

Looking in the code of the 2007 version, it was used for Siemens PLCs, which are used in the Iran nuclear enrichment program in Natanz. It was aimed at sabotaging the valves’ operations, by controlling the flow of uranium.

The list of new information goes on. According to Wired Magazine, the new finding, described in a paper released by Symantec on Tuesday (.pdf), resolves a number of longstanding mysteries around a part of the attack code that appeared in the 2009 and 2010 variants of Stuxnet but was incomplete in those variants and had been disabled by the attackers.
