Security researchers have detected a new Trojan, scarily similar to the infamous Stuxnet worm, which could disrupt computers controlling power plants, oil refineries and other critical infrastructure networks.
The Trojan, dubbed “Duqu” by the security firm Symantec, appears, based on its code, to have been written by the same authors as the Stuxnet worm, which last July was used to cripple an Iranian nuclear-fuel processing plant.
“Stuxnet source code is not out there,” wrote F-Secure cybersecurity expert Mikko Hyppönen on his firm’s blog. “Only the original authors have it. So, this new backdoor was created by the same party that created Stuxnet.”
