The demonstration of a real-world hardware security flaw in hotel room keycard locks at this year's Black Hat information security conference in Las Vegas saw guests literally reaching for their deadbolts. . Last month, security engineer Cody Brocious demonstrated his attack against hotel locks made by Onity, which commands 50% of the hotel lock market, comprising somewhere between 4 million and 10 million locks. The attack capitalized on two flaws involving Onity's hotel keycard locks: Their memory could be arbitrarily accessed by an attacker, and the related communications data wasn't encrypted. As a result, once someone such as Brocious reverse-engineered the underlying communications protocol, they could trick the keycard lock into opening itself, using a bit of programming and $40 in parts available via sparkfun.com or Radio Shack.

Security researchers have discovered a serious vulnerability that may be present in many Ethernet device drivers that is causing the devices to broadcast sensitive information over networks. . .. Security researchers have discovered a serious vulnerability that may be present in many Ethernet device drivers that is causing the devices to broadcast sensitive information over networks . According to the IEEE's Ethernet standard, packets transmitted on an Ethernet network should be a minimum of 46 bytes. If, as sometimes happens with protocols such as IP, a higher layer protocol requires less than 46 bytes, the Ethernet frames are supposed to be padded with null data. However, researchers at @stake Inc., in Cambridge, Mass., have discovered that many drivers instead pad packets with data from previously transmitted Ethernet frames. This results in the device sending out sensitive information to other machines on the same Ethernet network. The type of data sent depends upon the device driver implementation, but it can range from data housed in the dynamic kernel memory, to static system memory allocated to the driver, to a hardware buffer located on the network interface card.
