‘Knock, knock! Who’s there?’ —Shakespeare
The malware, called “Regin”, is probably run by a western intelligence agency and in some respects is more advanced in engineering terms than Stuxnet. […]
Symantec said it was not yet clear how Regin infected systems but it had been deployed against internet service providers and telecoms companies mainly in Russia and Saudi Arabia as well as Mexico, Ireland and Iran. […]
“Nothing else comes close to this . . . nothing else we look at compares,” said Orla Cox, director of security response at Symantec, who described Regin as one of the most “extraordinary” pieces of hacking software developed, and probably “months or years in the making”. […] “Sometimes there is virtually nothing left behind – no clues. Sometimes an infection can disappear completely almost as soon as you start looking at it, it’s gone. That shows you what you are dealing with.”
