This means my old uploads are still on the server. Now I can see that Google Drive provides versioning. I didn’t back them up because I thought Google Drive is save and my data is stored all over the world (my fault I know). But I was using the Google Drive Sync client and all my Drive files got encrypted. My “normal” local files are not the problem because these files I backup.

CryptoLocker 2.0 only accepts payments via Bitcoin and locks users out of even more file types including images, music and video files, which the original CryptoLocker skipped. In December 2013, just four months after CryptoLocker was unleashed CryptoLocker 2.0 was released. The enormous success cybercriminals had with CryptoLocker ransomware encouraged many cyberthieves to create copycat software like, Locker. Given the then current price of $661 per Bitcoin, that would represent more than $27 million in payments received, not counting all the other payment methods. Four Bitcoin accounts associated with CryptoLocker were discovered and it was discovered that 41,928 Bitcoins had been moved through those four accounts between October 15 and December 18, 2013. After payments are received, the first 1024 bytes of an encrypted file are uploaded to the server and the server would then search for the associated private key.ĬryptoLocker infected over 250,000 machines within the first four months it was released in September 2013.
The payments have increased over time to 2 Bitcoins or about $460, if the original ransom isn’t paid before the deadline, Cryptolocker gives its victims a second opportunity to pay 10 Bitcoins ($2300) to use a service that connected to the command and control servers.
Initially victims are charged $100, €100, £100, two Bitcoins or other figures for various currencies. The cost to retrieve files from Cryptolocker vary over time and with the particular version being used. If payment is not received in three days victims are usually given a second opportunity to pay a much higher ransom to get their files back. Once files are locked, Cryptolocker then threatens to delete the private key needed to unlock the files if payment is not received within three days.Ĭryptolocker demands that payments be paid in the form of Bitcoins, CashU, Ukash, Paysafecard, MoneyPak or pre-paid cash vouchers. CryptoLocker is a ransomware virus that infects PCs via downloads from infected websites and email attachments sent to business professionals via a botnet called GameOver ZeuS.Ĭryptolocker is particularly nasty ransomware that uses a 2048-bit RSA key pair, uploaded to a command-and-control server, which it uses it to encrypt or lock files with certain extensions, and delete the originals.
