Wealthy Mexicans Getting Chipped in Case of Abduction 306

Because the number of abductions in Mexico has jumped almost 40% in the past 3 years, the wealthy are getting subcutaneous transmitters so they can be tracked when kidnapped. Xega, the Mexican security firm which makes the chips, has seen a sales jump of 13% this year. The company injects the crystal-encased chip, the size and shape of a grain of rice, into clients' bodies with a syringe. The chip then sends radio signals to a larger device carried by the client with a global positioning system in it. A satellite can then be used to find the location of the missing person. Things must be a lot worse in Mexico than I thought.

Interview With MIT Subway Hacker Zack Anderson 113

longacre writes "In his most extensive interview since the DefCon controversy emerged, MIT subway hacker Zack Anderson talks with Popular Mechanics about what's wrong with the Charlie Card, what happened at DefCon, and what it's like to tango with the FBI and the MBTA. The interview comes on the heels of Tuesday's court ruling denying motions by the MBTA to issue a preliminary injunction aimed at keeping the students quiet for a further five months."

New Attack Against Multiple Encryption Functions 130

An anonymous reader sends word of a paper presented a few days back by Adi Shamir, the S in RSA, that promises a new form of mathematical attack against a broad range of cryptographic ciphers. The computerworld.com.au report leans heavily on Schneier's blog entry from the Crypto 2008 conference and the attached comments. Shamir's paper has not been published yet. "[The new attack could affect] hash functions (such as MD5, SHA-256), stream ciphers (such as RC4), and block ciphers (such as DES, Triple-DES, AES) at the Crypto 2008 conference. The new method of cryptanalysis has been called a 'cube attack' and formed part of Shamir's invited presentation at Crypto 2008 — 'How to solve it: New Techniques in Algebraic Cryptanalysis.' The new attack method isn't necessarily going to work against the exact ciphers listed above, but it offers a new generic attack method that can target basically formed ciphers irrespective of the basic cipher method in use, provided that it can be described in a 'low-degree polynomial equation'... What may be the biggest outcome from this research is the range of devices in widespread use that use weaker cryptographic protection, due to power or size limitations, that are now vulnerable to a straightforward mathematical attack."
