How CTB Locker operates?

Ransomware applications in general utilize other forms of malicious software to infiltrate the victim’s computer. More likely than not the malware is in fact a backdoor Trojan horse. On that note you should definitely scan your device for other potential threats once you’ve dealt with CTB Locker. There’s a type of Ransomware that locks up your screen and uses scare tactics to make victims pay but does not encrypt user’s files. Unfortunately you are not dealing with this type but another that represents a far bigger challenge. Once inside this type of ransomware will begin complying an extensive list of your files in order to determine the ones that have been most often accessed and modified, i.e. your favorite files. Once that’s done the encryption will begin and soon your files will be replaced with copies that end up with a strange extension, rendering them completely inaccessible and unmodifiable. As if that’s not enough evidence, an explanatory message gets posted on your desktop, with instructions how you can get a decryption key.

At that point you are not left with much of a choice. You can either pay the ransom – something we feel strongly against and consider to be a completely last resort measure, or hope that someone breaks this encryption and shares it online. That is not impossible but not very likely, yet we feel it is a better option than allowing to be extorted. You can of course, and we hope you do, choose to try our method for getting your information back. While it is by no means a safe bet that it will be a success, at the very least you will not make things worse, something that is entirely probably if you choose to send money to cyber criminals.

How were you infected with CTB Locker?

It is a perfectly safe assumption that a Trojan horse virus was used to sneak CTB Locker behind your defenses. If you are wondering how you got the Trojan – through compromised executable files, downloaded and installed on your computer, albeit involuntarily, by none other than you.

  • E-mails have been used for fraud attempts and malware spreading for a long time. Be careful even if the e-mail seems to have been sent by a legitimate looking company or institution and always scan any attachments before trying to open them.
  • If you are using torrents or other forms of file sharing be extremely careful before and after downloading any files, especially if they contain an .exe extension. What we mean by before and after – before downloading a torrent file be sure to check if the file has been uploaded by a trusted uploader (although that is by no means a guarantee for safety) and after the download and before opening it be sure to thoroughly scan the file(s).
  • If you have an error for a missing or corrupted .dll file be mindful to look for a solution online. And by solution we mean information about your problem. Do not download a .dll file from some website that you have never been to. This is a surefire way to get a nasty malware surprise, most likely a Trojan horse.
