A newly unsealed FBI search warrant application illustrates yet another example of how the government deploys malware and uses sophisticated exploits in an attempt to bust up child pornography rings.
The 28-page FBI affidavit (text-only, possibly NSFW) was unsealed in a federal court in Brooklyn, New York earlier this month. It describes a North Carolina server hosting a Tor hidden service site. The setup was seized in February 2015, but law enforcement allowed it to run for two additional weeks as a way to monitor its nearly 215,000 users.
Currently, at least three men—Peter Ferrell, Alex Schreiber, and James Paroline—have been charged in connection with this site.
Ferrell, username "plowden23," is the target of the search warrant affidavit. Schreiber, 66, of Queens, was a former New York City schoolteacher. The two New York men have been released on bond.
Paroline remains in federal custody without bail in New Jersey. The criminal complaint against him states that "during an interview with law enforcement officers, defendant PAROLINE admitted" that while working at a nursery school and a summer camp counselor in New Jersey, he "inappropriately touched minor children."
Two of the lawyers for two of the suspects did not respond to Ars' request for comment.
Mia Isner-Grynberg, the federal public defender for Ferrell, told Ars: "Thanks for reaching out. I'm sorry, but I don't generally comment on pending cases."
Kelly Langmesser, an FBI spokeswoman, also declined to respond to specific questions. "Because this is an ongoing matter, we are not commenting on the case," she told Ars.
Legal warrant or not?
Legal experts told Ars that there are significant questions about precisely how the unnamed Tor site was breached, exactly how its "Network Investigative Tool" (or NIT, i.e., malware) works, how many of the users were outside of the judicial district, and if the seized server contained other non-criminal content.
