The Shadow Brokers

Also known asThe Shadow Brokers

The Shadow Brokers is a hacking group known for publishing troves of offensive cyber tools in 2016 and 2017 that it claimed were stolen from the NSA-linked Equation Group. The group is repeatedly associated in the provided content with leaks of sophisticated Windows SMB exploitation tools, including EternalBlue, EternalChampion, EternalRomance, and EternalSynergy, and with the April 14, 2017 "Lost in Translation" leak. The leaked material also included the NSA-developed FuzzBunch framework and other exploitation tools targeting Microsoft SMB vulnerabilities addressed by MS17-010. Content provided states that EternalBlue was later used in major ransomware outbreaks including WannaCry, NotPetya, and Bad Rabbit, and that EternalRomance was also used in NotPetya and Bad Rabbit. The group publicly said it had infiltrated the Equation Group, and later indicated plans to release additional vulnerabilities, including via a subscription model. The content does not provide high-confidence attribution of The Shadow Brokers to any specific state, but it consistently describes the leaked tools as allegedly stolen from the Equation Group, which is described as having suspected ties to the U.S. National Security Agency.
