Submission + - Buffer Overflow in RFID Passport Readers (wired.com)

epee1221 writes: "Wired ran a story describing Lukas Grunwald's Defcon talk on an attack on airport passport readers. After extracting data from the (read-only) chip in a legitimate passport, he placed a version of the data with an altered passport photo (JPEG2000 is used in these chips) into a writable chip. The altered photo created a buffer overflow in two RFID readers he tested, causing both to crash. Grunwald suggests that vendors are typically using off-the-shelf JPEG2000 libraries, which would make the vulnerability common."

Submission + - Forensics Expert says Al-Qaeda Images Altered

WerewolfOfVulcan writes: Wired reports that researcher Neal Krawetz revealed some veeeeeery interesting things about the Al-Qaeda images that our government loves to show off.

From the article: "Krawetz was also able to determine that the writing on the banner behind al-Zawahiri's head was added to the image afterward. In the second picture above showing the results of the error level analysis, the light clusters on the image indicate areas of the image that were added or changed. The subtitles and logos in the upper right and lower left corners (IntelCenter is an organization that monitors terrorist activity and As-Sahab is the video production branch of al Qaeda) were all added at the same time, while the banner writing was added at a different time, likely around the same time that al-Zawahiri was added, Krawetz says." Why would Al-Qaeda add an IntelCenter logo to their video? Why would IntelCenter add an Al-Qaeda logo? Methinks we have bigger fish to fry than Gonzo and his fired attorneys... }:-) The article contains links to Krawetz's presentation and the source code he used to analyze the photos.
