Warrant Authorized FBI to Track and Infect Computers with Malware
FBI USES DRIVE-BY HACKING TO TRACK USERS
Security researchers call the tactic a "drive-by download" in which a hacker infiltrates a high-traffic website to deliver the malware to large swaths of visitors. That simply means that the FBI first infects the target sites and then installs malware to tracks its users.
PARTICULARLY TARGETING DARKNET WEBSITES
As a result, the FBI were successful in tracking the IP address of as many as 25 individuals in this case. To the FBI's credit, it has owned up to these techniques in the past and tracked users across Tor before.
YOU MIGHT BE IN DANGER IF USING TOR
This sophisticated use of tracking malware comes out to be a great tool to help law enforcement find and arrest the terrible criminals. But, in past we had seen some evidence that the FBI is tracking innocent users of Tor anonymity network, as well.
Many are worried about this tracking tactic that is also used to track people legally visiting other suspicious sites like researchers or human rights workers.
