Russian hackers got NSA material.
On Thursday the Wall Street Journal reported that Russian hackers obtained highly sensitive material from the US National Security Agency. The material is said to be related to both network attack and network defense. It was obtained from a machine belonging to a contractor on which the sensitive information had been placed (Washington Post).
The most interesting aspect of the story is that the hackers are said to have targeted the contractor after "identifying the files through the contractor's use of a popular anti-virus software made by Russia-based Kaspersky Lab." Kaspersky software has the reputation of conducting very thorough scans of the machines it protects, behavior the company touts as a feature that enables its products to provide better protection against novel threats: "We aggressively protect our users and we’re proud of it," is how Kaspersky puts it (Nota Bene).
The breach is said to have occurred in 2015, but wasn't discovered until spring of 2016. Thus NSA would have discovered the problem weeks before the ShadowBrokers began leaking what the Brokers assert are Equation Group hacking tools. It's also shortly before the summer 2016 arrest of Hal Martin, the NSA contract worker who allegedly hoarded highly classified material in a shed at his Glen Burnie, Maryland, home. The material the ShadowBrokers have leaked appear to date to 2013 or so; it's unclear whether this latest revelation is connected to either the Brokers or Mr. Martin's case, but NSA veterans say off-the-record that they're not surprised by the latest incident, and some researchers are beginning, tentatively, to "connect the dots" (Motherboard).
