One of the most significant events in computer security happened in April 2017, when a still-unidentified group calling itself the Shadow Brokers published a trove of the National Security Agency’s most coveted hacking tools. The leak and the subsequent repurposing of the exploits in the WannaCry and NotPetya worms that shut down computers worldwide made the theft arguably one of the NSA’s biggest operational mistakes ever.
On Monday, security firm Symantec reported that two of those advanced hacking tools were used against a host of targets starting in March 2016, fourteen months prior to the Shadow Brokers leak.
