Extortion Virus Code Cracked

Posted by ryuzaki0 on from the unlock-your-stuff dept.

Billosaur writes "BBC News is reporting that the password to the dreaded Archiveus virus has been discovered and is now available to anyone who needs it. Archiveus is a 'ransomware' virus, which combines files from the My Documents folder on Windows machines and exchanges them for a single, password-protected file, which it will not unlock unless a password is given. The user would normally be required to pay the extortionist money in order to receive the password, but apparently the virus writer made one small, critical error in coding: placing the password in the code. BTW, the 30-digit password locking the files is mf2lro8sw03ufvnsq034jfowr18f3cszc20vmw."

      Public key cryptography does not work against a man in the middle attack.

      True, in general, though precautions can be taken. I fail to see how a MITM attack is even relevant here, though.

      When the files are being encrypted by software running on your computer, such a virus is inevitably vulnerable.

      Why? Virus contains public key, generates random session key (ideally in memory-locked pages that cannot be swapped out), encrypts all your data with session key, encrypts session key with public key, writes encrypted session key to a file, wipes session key from memory, then shuts down.

      Assuming you don't notice the virus before all of this happens, you're toast unless you can get a copy of the private key.

      To overcome this flaw, the virus writer would have to send the files to a pre-known IP address for off-site encryption (which among other problems would probably be a pretty noticeable activity). Doing so would presumably also expose the author to risk that the computer in question (and presumably he himself) could be siezed.

      Did you mean decryption? If so, yes, the writer would have to have you ship your session key file to him so he could decrypt it and give you your unique decryption key. I don't think that activity is nearly as risky to the writer as trying to figure out how to collect the money, though. Following money trails is something the world's law enforcement agencies are very good at.

      You are absolutely wrong. PKI was designed with the purpose of preventing man-in-the-middle attacks. The virus writer would include the public key in the virus with an associated encryption algorithm. The problem arised with decryption. In order to decrypt a file you would need an associated private key. Now if this key is available inside the virus it would be just as easy to find as the password within the article.

      In fact the whole idea of cryptography revolves around the encryption algorithm telling you nothing about a method to decrypt the data it encrypts (At least without a certain key). These are called trapdoor one-way functions.

      The most realistic way I can think of writing such a virus would be to provide and encryption algo in the virus and then provide a decryption program when the intended victim has paid you the money. Now aren't you glad I'm not writing viruses?

    If you are still betting on antivirus companies to keep you safe, you should consider this a warning. There is no technical reason why the password should be recoverable. Had the author used strong public key cryptography instead of a symmetric cypher, there would be no way to get the key without the help of the virus author. The only way to be safe is to not get infected and that means you have to use your brain.

They politely ask the registar to hand over all information on the person paying for the domain name (for the definition of polite which involves pointing guns at and kicking people in the head). Once they know who is paying for the web sites (credit info/check info), they visit that person and politely ask for the password to unlock the virus (same definition of polite).
