US court rules that FBI can hack into a computer without a warrant
A U.S. court has ruled that the FBI can hack into a computer without a warrant — a move which is troubling privacy advocates.
The criminal case involves a child pornography site, Playpen, that had been accessible through Tor, a browser designed for anonymous web surfing.
The FBI, however, managed to take over the site in 2014, and then tracked down and arrested its members by hacking their computers. This allowed law enforcement to secretly collect their IP addresses.
