Technical summary of breaking into Breach-Forums by FBI.
Apparently, Conor was using his personal internet connection to operate the darknet platform and apparently did not use TOR/VPN once in 2022 due to connection failure or forgetfulness. This IP led FBI to him.
It also seems that the FBI had access to the logs of the server somehow. Likely a Zero-day in the web component.
