Researchers use children's toy to exploit security hole in feds' radios, eavesdrop on conversations
Researchers from the University of Pennsylvania have discovered a potentially major security flaw in the radios used by federal agents, as part of a new study that's sure to raise some eyebrows within the intelligence community. Computer science professor Matt Blaze and his team uncovered the vulnerability after examining a set of handheld and in-car radios used by law enforcement officials in two, undisclosed metropolitan areas. The devices, which operate on a wireless standard known as Project 25 (P25), suffer from a relatively simple design flaw, with indicators and switches that don't always make it clear whether transmissions are encrypted. And, because these missives are sent in segments, a hacker could jam an entire message by blocking just one of its pieces, without expending too much power. What's really shocking, however, is that the researchers were able to jam messages and track the location of agents using only a $30 IM Me texting device, designed for kids (pictured above). After listening in on sensitive conversations from officials at the Department of Justice and the Department of Homeland Security, Barnes and his team have called for a "substantial top-to-bottom redesign" of the P25 system and have notified the agencies in question. The FBI has yet to comment on the study, but you can read the whole thing for yourself, at the link below.
Mattel's IM-Me offers up lame-o messaging, guards against predators
Brand new toys sure have been popping up everywhere of late, and now Mattel's hitting us up with another gizmo being showcased at the International Toy Fair. Presumably designed to latch onto the hard-earned dollars of paranoid mums who watch entirely too many of those "internet predator" spots, the Girl Tech IM-Me is a very restrictive wireless instant messaging system that relies on parental okays in order to operate. Aside from only allowing texts to be sent and received from parent-approved usernames, the gal can only use her purple and pink IM machine within range (read: in the house) of the USB dongle, which must be plugged into an internet connected PC. So while we still prefer PictoChat, we imagine this $64.99 device will sell like hotcakes when it lands this summer -- only to never be used by any halfway sane (and understandably rebellious) teenage daughter.[Via Gadgets-Weblog]
