Really interesting research demonstrating how to hide vulnerabilities in source code by manipulating how Unicode text is displayed. It’s really clever, and not the sort of attack one would normally think about. From Ross Anderson’s blog: We have discovered ways of manipulating the encoding of source code files so that human viewers and compilers see … Read More “Hiding Vulnerabilities in Source Code” »

This is a really interesting research result. This paper proves that two parties can create a secure communications channel using a communications system with a backdoor. It’s a theoretical result, so it doesn’t talk about how easy that channel is to create. And the assumptions on the adversary are pretty reasonable: that each party can … Read More “Subverting Backdoored Encrryption” »

It’s a lot more chemistry than I understand: Invisible inks based on “smart” fluorescent materials have been shining brightly (if only you could see them) in the data-encryption/decryption arena lately…. But some of the materials are costly or difficult to prepare, and many of these inks remain somewhat visible when illuminated with ambient or ultraviolet … Read More “New Research in Invisible Inks” »

Interesting: “We used silver and carbon ink to print an image consisting of small rods that are about a millimeter long and a couple of hundred microns wide,” said Ajay Nahata from the University of Utah, leader of the research team. “We found that changing the fraction of silver and carbon in each rod changes … Read More “Hiding Information in Silver and Carbon Ink” »

There’s new malware toolkit that uses steganography to hide in images: For the past two months, a new exploit kit has been serving malicious code hidden in the pixels of banner ads via a malvertising campaign that has been active on several high profile websites. Discovered by security researchers from ESET, this new exploit kit … Read More “WWW Malware Hides in Images” »
