From an article about Zheng Xiaoqing, an American convicted of spying for China: According to a Department of Justice (DOJ) indictment, the US citizen hid confidential files stolen from his employers in the binary code of a digital photograph of a sunset, which Mr Zheng then mailed to himself.

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” »
NASA made an oblique reference to a coded message in the color pattern of the Perseverance Mars Lander ‘s parachute. More information. Powered by WPeMatico
Artist Katie Holten has developed a tree code (basically, a font in trees), and New York City is using it to plant secret messages in parks. Powered by WPeMatico
This is a fun steganographic application: hiding a message in a fingerprint image. Can’t see any real use for it, but that’s okay. Powered by WPeMatico
Interesting research in steganography at the font level. Powered by WPeMatico
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” »
In this era of electronic leakers, remember that zero-width spaces and homoglyph substitution can fingerprint individual instances of files. Powered by WPeMatico
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” »
