From the Wired article, "Instead of going for the easy bust, the FBI spent a solid year surveilling McGrath, while working with Justice Department lawyers on the legal framework for what would become Operation Torpedo. Finally, on November 2012, the feds swooped in on McGrath, seized his servers and spirited them away to an FBI office in Omaha.
A federal magistrate signed three separate search warrants: one for each of the three hidden services. The warrants authorized the FBI to modify the code on the servers to deliver the NIT to any computers that accessed the sites. The judge also allowed the FBI to delay notification to the targets for 30 days."
The FBI modified the .onion sites to serve a malicious script which was used to de-anonymize users. It's worth noting that only those using Tor improperly would be vulnerable. The FBI tracking payload required scripting to be enabled in the browser--a common blunder among inexperienced Tor users.

Unfortunately, an in-depth study of child-porn convicts released back in '09 showed that 85% of them *had* also molested at least one kid:
My guess is that a lot of cops only truly go "bad" after spending years watching perps like that go free due to insufficient evidence or other technicalities...

Just a heads up; the "Butner Study" has been getting criticism from many quarters because the data is being misused by prosecutors and LEOs.
Even the original authors have commented on the misuse.
