BOSTON AP – A federal judge Tuesday lifted a gag order on three MIT students who were barred from talking publicly about security flaws they discovered in the state’s automated mass transit fare system, even as a lawyer for the agency acknowledged the system was “compromised.”

U.S. District Judge George O’Toole Jr. rejected a request by the Massachusetts Bay Transportation Authority to impose a five-month injunction blocking the students from revealing anything about the security system. O’Toole also dissolved a temporary restraining order that had prohibited the students from speaking about their findings this month at DefCon, an annual computer hackers’ convention in Las Vegas.
