MIT students free to talk about bugs in Boston bus systemThree MIT students who'd been blocked by a judge from presenting their findings on "vulnerabilities in Boston's transit fare payment system" at this month's Defcon security conference are free to speak starting Friday. A U.S. District Court judge refused to extend the 10-day gag order issued against Zack Anderson (pictured), RJ Ryan, and Alessandro Chiesa just before the conference. The Massachusetts Bay Transportation Authority had asked for a five-month restraining order to allow time to fix the vulnerabilities. San Francisco's Electronic Frontier Foundation represented the students. (Photo by Zack Anderson)
