Operation Pacifier

Operation Pacifier is or was a large scale hacking campaigning from the FBI launched in 2015 investigating criminal activity on the dark web. It was the largest such operation since Operation Torpedo.[1]

Malware known to law enforcement as network investigative techniques (NITs) were used to discover the real IP addresses of Tor users from a seized child porn website called Playpen.[2]

The international nature of the operation raised a number of legal questions about the FBI's international jurisdiction and is the subject of ongoing legal and journalistic investigations.[3]
