Russians Hackers Used Twitter, Photos to Reach U.S. Computers

Russian government-backed hackers who penetrated high-profile U.S. government and defense industry computers this year used a method combining Twitter with data hidden in seemingly benign photographs, according to experts studying the campaign. In a public report Wednesday, researchers at security company FireEye Inc said the group used the unusual tandem as a means of communicating with previously infected computers. The tweeted information included a website address, a number and a handful of letters. Vikram Thakur, a senior manager at Symantec Corp, said his team had also found Twitter controls combined with hidden data in photos, a technique known as steganography.
