Unfortunately, you'll never be able to crack it, because you don't know what the key was. Since XOR encryption is so weak, this should be no sweat to crack, right? I've encrypted a short message of ten bytes, by XORing it with a random sequence of ten bytes. Type in the wrong key, and the files appear scrambled.Īlthough what these guys did is unpardonable. Properly, it shouldn't be a "password" at all, but a decryption-key you type before accessing the files.
Encryptstick disk not found password#
There is no reason a device like this needs to store the password at all. I mean, if you have the jumprdrive in your possession it's only a matter of time before you find a weakness to exploit, right? (Thus it demonstrates a core flaw of DRM, etc) That famous saying only applies if the machine gets some ongoing use after the hacker has physical access. but getting his hands on it once won't help. If the hacker installs a keylogger, and I don't detect the intrusion when I return, then a second trip to physical access could break the security. He's mathmatically less likely to brute force that encryption than if he sniffed encypted email or SSL sessions. If my harddrive contains an encrypted filesystem, it does a "hacker" no good to steal my PC. "No machine is secure if the physical box is in the hands of the hacker/criminal." All the alarm bells have already gone off, and I never even stepped into it with a debugger to learn how they fold your password into a key, or what the IV was, or what the encryption algorithm itself was. I figure if I can find all those holes in an hour of poking around with a hex tool, I know they didn't actually hire any cryptographers to produce the software. That means it's at least more than a plain old 8-byte XOR cypher using a folded password. So the IV for the encryption routine is fixed as well.Īt least XORing blocks of encrypted binary nulls with two different keys didn't quickly reveal any obvious common bits, nor did encrypting two successive blocks that differed only by a single bit of plaintext. AAAAAAAA encoded in one file produces exactly the same results as AAAAAAAA encoded in another. (Please note that these are just example values with nice visual properties, and not the exact values I saw!)Īlso, the encryption is the same from file to file. If I learn what your first block means, I know the third block means exactly the same data. When I changed that to AAAAAAAAbbbbbbbbAAAAAAAA I saw the following encoding: 12345678abcdefgh12345678. It will encrypt to an 8-byte repeating block on the drive, like this: 123456781234567812345678
If you have a file containing AAAAAAAAAAAAAAAAAAAAAAAA Its biggest readily apparent weakness is that the encryption algorithm is running in ECB mode.

It appears to be using a 64 bit block cypher (perhaps DES) which pretty much rules out any of the more modern encryption algorithms.

I spent a little while analyzing the "CruzerLock" software that came with my Cruzer Mini USB drive. Don't look to San Disk for any better security.
