NSA Contractor Arrested in Biggest Breach of U.S. Secrets Pleads Guilty

But perhaps the most damaging leak of all was discovered around the time of Mr. Martin’s arrest in August 2016, when a mysterious group calling itself the Shadow Brokers announced an online auction of a long list of software exploits the N.S.A. used to break into foreign computer networks. Investigators at first believed Mr. Martin might be the Shadow Brokers, who had posted their first announcement of their auction of N.S.A. hacking tools a half-hour after Mr. Martin blocked the two Kaspersky workers on Twitter. It appears that the investigators eventually concluded that Mr. Martin was not the source of the Shadow Brokers’ material, at least not wittingly.
