CryptoLocker Ransomware

CryptoLocker Ransomware Description

CryptoLocker Ransomware Image 1The CryptoLocker Trojan is a ransomware infection that encrypts the victim's files. CryptoLocker may typically be installed by another threat such as a Trojan downloader or a worm. Once CryptoLocker is installed, CryptoLocker will search for sensitive files on the victim's computer and encrypt them. Essentially, CryptoLocker takes the infected computer hostage by preventing access to any of the computer user's files. CryptoLocker then demands payment of a ransom to decrypt the infected files. CryptoLocker is quite harmful, and ESG security analysts strongly advise computer users to use an efficient, proven and updated anti-malware program to protect their computer from these types of infections.

The Outrageous Fee Asked by CryptoLocker

CryptoLocker displays an alarming message when the infected computer starts up. This message demands payment of 100 USD or Euro in order to decrypt the infected files. CryptoLocker also claims that attempting to remove CryptoLocker may result in the victim's files being locked forever. The CryptoLocker ransom message reads as follows:

'Your personal files are encrypted!
Your important files encryption produced on this computer: photos, videos, document, etc. Here is a complete list of encrypted files, and you can personally verify this…
To obtain the private key for this computer, which will automatically decrypt files, you need to pay 100 USD / 100EUR / similar amount in another currency.'

To scare inexperienced computer users so that they will not take action to remove CryptoLocker, the ransom message continues by stating the following:

'Any attempt to remove or damage this software will lead to immediate destruction of the private key server.'

Why Paying CryptoLocker's Ransom is not Going to Help Your PC

There are several reasons why you should not pay CryptoLocker's ransom. You can see below some of them:

  1. There is no guarantee that paying CryptoLocker's ransom will decrypt your files.
  2. Paying this 'fee' will support malware developers, allowing them to create additional malicious content and target other computer users.
  3. Taking steps to remove CryptoLocker with a legitimate security program will not actually endanger your files or prevent you from decrypting them.

In several situations, it may be needed to use an additional decryption utility to restore your files to normal, usually from an external memory device. However, the best way to restore your files is to have a back-up at hand, a good security practice for all computer users.

    The ransom is now $300.

  • kishore:

    my machine has been attacked by the Cypto Locker ransomware, i remove but cannot open any files can you please help me how to decrypt these files

  • Harry Blazier:

    I have traced this malware to this file. PendingRename. This file will not allow me to remove/delete. Every time this file is regenerated, a new rename file appears. I have also used Hitman, and defender. Nothing has even found this problem. 2 days of tracking has led me to this finding!

  • Orval:

    I defeated a cryptolockup by rebooting from a cold start in safe mode, starting control panel and selecting Restore to an earlier but recent date. Worked for me.

  • MIchael Keller:

    I was hit with the Cryptolocker virus last fall. I have since removed it but the files are still encrypted. This includes many family pictures etc. it is this format: img 0862.jpg 1478 kb ebgwwxc file
    I have tried to use Pandaware ransomware to decrypt but it isn't working.

  • seymour:

    Just attacked our computer systems in the UK pretended from HSBC bank , sadly it was opened and hey presto system damaged. Recommend everyone to take a hard back up copy each month so you have something to go back to.

  • Danos:

    Make sure that ALL your backup drive(s) and/or Folders/directories are password protected. If not then Cryptolocker will attack your backups as well. If they are password protected they cannot be touched. It is important to do this, otherwise you may be unpleasantly surprised that your backups are non-recoverable.

  • Scott:

    I have a memory card that has a file of images blocked with CRYPTO BLOCKER. The files were never on the hard drive, only the memory card. Three computers I have put the memory card into register close to 900MB of data. This seems like too much data for the virus to have removed all the files from the card. Is there anyone who has had REAL success in decrypting these CRYPTO BLOCKER files?? Why is there so much data still reading on the card if the files are gone!?! Are there any memory card data recovery programs available? I am willing to pay a certain amount of money to someone who can demonstrate success in opening these files.Serious inquiries only please…

  • Andrew Wilson:

    On July 30 @ 7:30 PST i turned on my screen to find a note that said "oh no.. what happened to all your files & folders?"
    Not knowing what this was, I closed the page and restarted my computer.
    When it restarted I noticed it was not a good thing, EVERY DRIVE in my computer (4) was encrypted, and i must pay $500.00 USD (in Bitcoins) and they would send me a "secret key" to unlock.
    Needless to say, i have THOUSANDS of vacation photos, wedding, grad photos on their. LUCKY for me i have these saved "in the cloud" but all my personal email folders, word documents and my small business data is all done.
    Is it worth sending the money and "hope" i get the secret key back and support these (*)-holes and fund their multi million dollar fund. NO
    After speaking with my local NCIX computer store and reading & (trying) the solves on from You Tube i decided to kill all my drives and have a TALL drink and lick my wounds.
    Just thought i would share my story

  • Scott:

    My father was conned today by these scum bags the going rate (22.9.15) is $500AUD.He received a cold call phone call informing him he had a virus on his computer.

    I just happened to drop in just as they were going to begin installing the malware and begin encrypting his files. Credit card stopped.

    I cannot believe in this day and age people are still getting done by these scum.

    My PC be attacked by the Crypto Locker ransomware on Dec.13,2015. Though I had deleted the ransomware and PC can work normally, All the saved file become JPG. v.v.v., doc.v.v.v., - - .I can not open those v.v.v.file. Could you please advise me how to decrypt these files?

  • Bobbie:

    The ransom demanded from me was $700 USD. I am retired and on social security so obviously can not afford to pay these horrible people. I let the Crypto virus in on my computer by foolishly clicking on a pop-up request to update my Adobe Flash player. I understand that Java pop-ups can also be fakes as well. Just wanted to put that out there. I lost years of work I had done on a Genealogy project. I had backed up a lot of info on flash drives, but certainly not all of it. Makes me sick how these people can get away with this. Lost hundreds of photos and several thousand music files.

  • Marjolein:

    Just got the virus and it has encrypted all my photos and the ransom they are asking is 700 US Bitcoin dollars, makes me sick.

  • jess:

    ive got encripted files and had to format my mac cos i got infected with paralels,how caan i restore my videos

  • LB:

    You cannot decrypt encrypted files.
    You must restore them from your backup.
    You do have a backup??
    If not. Pay and hope they will decrypt them or say goodbye to your files.
    And by the way, you should never use the computer normally with an account that has installation privileges. Change to an account with higher privileges ONLY when you need to install something.
