Judges OK evidence from hacker vigilante

A federal appeals panel ruled this week that the government did not violate search and seizure laws when it used evidence that a hacker gathered to establish a child pornography case.

The opinion reverses a lower court ruling in which a U.S. District Court judge in Virginia suppressed the evidence, saying the government had violated a defendant's rights.

The decision stems from a case in which a hacker uploaded a file to a child porn newsgroup that made it possible to track who downloaded files from the service. The uploaded file contained the SubSeven virus, which the hacker used to remotely search people's computers for porn.

The hacker then played the role of a cybervigilante, sending anonymous tips to law enforcement officials that alerted them to child porn files the hacker had found on people's PCs.

The attorneys for one of the men nabbed in the hacker's sting sued, saying that the hacker was acting as an agent of the government and therefore needed a warrant before conducting a search of someone's computer. A federal court judge ruled that the government had indeed violated the man's Fourth Amendment rights protecting him from unreasonable search and seizure.
