Hackers have managed to penetrate computer networks associated with the Israeli military in an espionage campaign that skillfully packages existing attack software with trick emails, according to security researchers at Blue Coat Systems Inc.
The four-month-old effort, most likely by Arabic-speaking programmers, shows how the Middle East continues to be a hotbed for cyber espionage and how widely the ability to carry off such attacks has spread, the researchers said.
Waylon Grange, a researcher with the Blue Coat, who discovered the campaign, said the vast majority of the hackers’ software was cobbled together from widely available tools, such as the remote-access Trojan called Poison Ivy.
The hackers were likely working on a budget and had no need to spend much on tailored code, Grange said, adding that most of their work appeared to have gone into so-called social engineering, or human trickery.
The hackers sent emails to various military addresses that purported to show breaking IDF news and other lures. Some of the emails included attachments that established “back doors” for future access by the hackers and modules that could download and run additional programs, according to Blue Coat.
Using standard obfuscation techniques, the software was able to avoid detection by most antivirus engines, Blue Coat said. At least some software lodged inside government computers, because Blue Coat detected it “beaconing,” or sending signals to the hackers that it was in place.
An Israei defense ministry spokeswoman referred questions to the military. Military officials said they were “not aware of hacking on IDF operational networks.”
Blue Coat provided Reuters with an advance look at its findings and intends to publish a paper later. The security firm, based in Sunnyvale, California, is set to be acquired by private equity firm Bain Capital LLC.
Citing confidentiality agreements with clients, Blue Coat declined to say exactly where the campaign worked, and Grange said he did not know if any vital data had been stolen.
