Wednesday’s Wall Street Journal, one of the first news sources to break the story, reported that Kaspersky itself had been hacked by malware whose code was remarkably similar to that of a virus attributed to Israel. Code-named “Duqu” because it used the letters DQ in the names of the files it created, the malware had first been detected in 2011. On Thursday, Symantec, another cyber-security firm, announced it too had discovered Duqu 2 on its global network, striking undisclosed telecommunication sites in Europe, North Africa, Hong Kong, and Southeast Asia. It said that Duqu 2 is much more difficult to detect that its predecessor because it lives exclusively in the memory of the computers it infects, rather than writing files to a drive or disk.
The original Duqu shared coding with — and was written on the same platform as — Stuxnet, the computer worm that partially disabled enrichment centrifuges in Iranian nuclear power plants, according to a 2012 report in The New York Times. Intelligence and military experts said that Stuxnet was first tested at Dimona, a nuclear-reactor complex in the Negev desert that houses Israel’s own clandestine nuclear weapons program. While Stuxnet is widely believed to have been a joint Israeli-U.S. operation, Israel seems to have developed and implemented Duqu on its own.
