Russian state hackers stole classified cyberattack and defense tools and information from NSA contractor’s home computer, WSJ report says. The hack reportedly occurred via Kaspersky Lab antivirus software on the contractor’s computer, where the AV flagged the NSA cyberspying tools and code. The breach wasn’t detected until the spring of 2016, and wasn’t known publicly until today. This marks the third case of an NSA contractor exposing or leaking classified information, security experts say. The case is under investigation by the federal government.”]
