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.

This whole story fits into the principle that "bad facts make bad law." It's hard to overlook the fact that extremely scummy people were busted here, and the Government relies on this emotional reaction to get much wider powers. I'm sure the evidence will ultimately be admitted because of the "bad facts" principle, which will open the door to Federal malware anywhere.

Scummy, or just gross?
Given how often the cops ignore the abusers since it takes a lot of effort to get them versus snagging basement-dwelling pervs who have whacking it to 20-year old photos, it seems reasonable to ask if there is any evidence that any of the people who were arrested were producers or had even provided incentive to some one else to harm a child by producing the abuse images?
I wish we lived in a country where the cops were selfless instead of self-serving, but their lack of ethical standards invites such doubts.

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.
