Encrypted Images Vulnerable To New Attack 155
rifles only writes "A German techie has found a remarkably simple way to discern some of the content of encrypted volumes containing images. The encrypted images don't reveal themselves totally, but in many cases do let an attacker see the outline of a high-contrast image. The attack works regardless of the encryption algorithm used (the widely-used AES for instance), and affects all utilities that use single symmetric keys. More significant to police around the world struggling with criminal and terrorist use of encryption, the attack also breaks the ability of users to 'hide' separate encrypted volumes inside already encrypted volumes, whose existence can now for the first time be revealed." The discoverer of this attack works for a company making full-disk encryption software; their product, TurboCrypt, has already been enhanced to defeat the attack. Other on-the-fly encryption products will probably be similarly enhanced, as the discoverer asserts: "To our knowledge is the described method free of patents and the author can confirm that he hasn't applied for protection."

Can you tell us what you figured out so we can RYFC instead of TFA?

You didn't look close enough, there was a hidden volume inside!
