CryptoLocker is a virus, Trojan, or malware on one code that attempts to seek money from computer users. This kind or computer infection can be considered as ransomware. However, it will not lock the computer and demands for payment to obtain the unlock code. CryptoLocker encrypts entire files on the infected computer and requires user to get the private key that is needed for decryption. What also differentiates CryptoLocker from other ransom virus is its time-based destruction of key. Failure to pay the private key on specified time will destroy the key from the server. It simply means, there is no way that you can unlock all affected files on the computer.
CryptoLocker message states the following:
“Your personal files are encrypted!
Your important files encryption produces on this computer: photos, videos, documents, etc. Here is a complete list of encrypted files, and you can personally verify this.
Encryption was produced using a unique public key RSA-2048 generated for this computer. To decrypt files, you need to obtain the private key.
The single copy of the private key, which will allow you to decrypt the files, located on a secret server on the Internet; the server will destroy the key after a time specified in this window. After that, nobody and never will be able to restore files…
To obtain the private key for this computer, which will automatically decrypt files, you need to pay 100 USB / 100EUR / similar amount in another currency.
Click Next to select the method of payment and the currency.
Any attempt to remove or damage this software will lead to the immediate destruction of the private key by server.”
As you can see, author of CryptoLocker virus intends to collect money by locking files on the infected computer. Whether or not the content of the window is true, we still do not encourage paying for the private key to be able to resolve the issue. First you need to remove CryptoLocker from the computer. Then, decrypt all files with valid tools.
Different anti-virus and anti-malware programs may name this threat according to their patterns. Here are some detection names: Trojan.Cryptolocker.F
