Researchers say the same weapons-grade attack kit was used in a much-earlier and possibly larger-scale hack. The earlier, previously unknown attack used an exploit codenamed EternalBlue and a backdoor called DoublePulsar. Instead of installing WannaCry, the campaign pushed cryptocurrency mining software known as Adylkuzz. The botnet then mined Monero, a cryptocurrency that bills itself as being fully anonymous, as opposed to Bitcoin. The revelation raises the possibility that other botnets have been built on the shoulders of the NSA but have yet to be identified.”]
