WSJ has a major scoop today. From a report: The Russian government used a popular antivirus software to secretly scan computers around the world for classified U.S. government documents and top-secret information, modifying the program to turn it into an espionage tool (could be paywalled), according to current and former U.S. officials with knowledge of the matter. The software, made by the Moscow-based company Kaspersky Lab, routinely scans files of computers on which it is installed looking for viruses and other malicious software. But in an adjustment to its normal operations that the officials say could only have been made with the company's knowledge, the program searched for terms as broad as "top secret," which may be written on classified government documents, as well as the classified code names of U.S. government programs, these people said. The Wall Street Journal reported last week that Russian hackers used Kaspersky's software in 2015 to target a contractor working for the National Security Agency, who had removed classified materials from his workplace and put them on his home computer, which was running the program. The hackers stole highly classified information on how the NSA conducts espionage and protects against incursions by other countries, said people familiar with the matter. But the use of the Kaspersky program to spy on the U.S. is broader and more pervasive than the operation against that one individual, whose name hasn't been publicly released, current and former officials said.
