    What is Crypt0L0cker Ransomware?

    Crypt0L0cker (or TorrentLocker) is a ransomware infection that infiltrates computers using infected email message attachments (message topics often include: “package tracking”, ”speeding tickets”, “unpaid invoice”, etc.) Note that cyber criminals localise these spam email messages to make them appear legitimate. For example, computer users located in the United Kingdom receive fake email messages claiming to be package tracking messages from Royal Mail, PC users from Australia receive messages from Australia Post, etc. After successful infiltration, this malware encrypts files on victims' computers and demands ransom payments of 2.2 Bitcoin to decrypt them. Crypt0l0cker ransomware (some newer variants use the name CryptoLocker) encrypts all files found on victims' computers except the following: .html, .inf, .manifest, .chm, .ini, .tmp, .log, .url, .lnk, .cmd, .bat, .scr, .msi, .sys, .dll, .exe, .avi, .wav, .mp3, .gif, .ico, .png, .bmp, and .txt (files needed for normal Windows operation).

    Successfully encrypted files receive a .encrypted prefix in dedicated folders containing encrypted files. Crypt0l0cker provides DECRYTP_INSTRUCTIONS.html and DECRYPT_INSTRUCTIONS.txt files with instructions on how to pay the ransom. This ransomware is targeted at computer users from Australia, Austria, Canada, Czech Republic, Italy, Ireland, France, Germany, Netherlands, Korea, Thailand, New Zealand, Spain, Turkey, and the United Kingdom. This is an updated variant of malware previously known as TorrentLocker. Cyber criminals responsible for creating Crypt0l0cker ransomware use TOR network to collect ransom payments from victims. TOR network ensures that criminals' identities and locations remain anonymous.

    Ransomware infections such as Crypt0L0cker (including CryptoWall, TeslaCrypt, and CTB-Locker) present a strong case to maintain regular backups of your stored data. Note that paying the ransom as demanded by this ransomware is equivalent to sending your money to cyber criminals - you will support their malicious business model and there is no guarantee that your files will ever be decrypted. To avoid computer infection with ransomware infections such as this, express caution when opening email messages - cyber criminals use various catchy titles to trick PC users into opening infected email attachments. At time of writing, no tools were available to decrypt files affected by Crypt0locker malware without paying the ransom.

    How Crypt0L0cker infected your PC

    Crypt0L0cker infiltrates computers using fake phishing e-mails from post service. To make it look more “real” hackers send e-mails from Royal Mail in United Kingdom or Australia Post in Australia. Those e-mails contain malicious attachments with archived documents. This documents have built-in macros, that will download core executable file of the virus. Hackers use TOR network and Bitcoin payments to prevent possibility of tracking and anonymity. In order to prevent infection with this type of threats we recommend you to use SpyHunter and HitmanPro with Cryptoguard.

    Paying the demanded amount of money will restore your access to your files, won’t it?

    As you already know, you are facing the worst of the worst when it comes to cyber threats. You cannot expect to be treated fairly by the hackers, who have created .Enc File Encryption (Crypt0l0cker Virus). Really, what reasons can you possibly have to trust them? They have infected your machine with two horrible versions of malware and now all they want is your money. It is possible that they might take your money, without unlocking your encrypted data. It is also possible that the cyber criminals will be willing to recover your control over your files. What to do is totally up to you.
