WASHINGTON: US security firm Symantec has warned of a new computer virus similar to the malicious Stuxnet worm believed to have preyed on Iran’s nuclear programme.

Symantec said on Tuesday that the new virus, dubbed “Duqu” because it creates files with the file name prefix “DQ,” is similar to Stuxnet but is designed to gather intelligence for future attacks on industrial control systems. “The threat was written by the same authors (or those that have access to the Stuxnet source code) and appears to have been created since the last Stuxnet file was recovered,” Symantec said on its website.

“Duqu’s purpose is to gather intelligence data and assets from entities, such as industrial control system manufacturers, in order to more easily conduct a future attack against another third party.

“The attackers are looking for information such as design documents that could help them mount a future attack on an industrial control facility.”—AFP
