That's it CryptoLocker is a particularly insidious form of family malware Ransomeware which was first spotted in 2013 in September. Malicious software encrypts files on infected computers and requires its victims to pay ransom in order to retrieve access to locked files.
Το CryptoLocker κρυπτογραφεί τα δεδομένα του θύματος με μια πολύ ισχυρή μέθοδο κρυπτογράφησης. καθιστώντας ουσιαστικά αδύνατη την πρόσβαση στα αρχεία αν δεν καταβληθούν τα λύτρα στους εγκληματίες. Το ποσό κυμαίνεται από 100 έως και 300 δολάρια σε Bitcoins, εξαρτάται από τον "τιμοκατάλογο". Καμιά φορά το πόσο μπορεί να είναι πολύ αυξημένο, εξαρτάται πάντα από τον εγκληματία και το είδος τους στόχου του.
Once the malicious software locks the computer, it gives the victim 72 hours to pay for the ransom, otherwise the blackmail will delete the decryption key, which is the only way for the encrypted files to reappear.
What can happen if your computer gets infected? The answer is disappointing. There is currently no decryption solution if you do not have the decryption key. Encryption used by criminals is an encryption in the 2048 bit and is almost impossible to break.
However, because prevention is always one of the best safety techniques, here are some ways to help prevent a possible CryptoLocker infection:
- It has been reported that most viruses were delivered through an email containing infected attachments. Avoid opening attachments from strangers or clicking links that come with spam emails. They usually lead to malware. Generally avoid opening emails and attachments files from unknown sources, especially when they come in .zip or .rar.
- Most have an anti-virus program, but do you know if it is effective? Make sure it is reliable and always up to date.
- Always update your operating system and the software you have installed on your computer.
- Always (and as often as possible) keep copies security. (Tip: Before keeping a backup make sure your computer is clean.)
- Create cloud accounts for file storage and off-computer.
- Windows 7 users users should create points επαναφοράς του συστήματος τους και οι χρήστες των Windows 8,it would be good if they set them to keep the file history.
- Make sure you format your hard disk and that the CryptoLocker trojan has been deleted altogether before attempting to reinstall Windows or restore your files from a backup.
There are many free tools that can be of great help in protecting your systems from this malware.
1. CryptoPrevent, was created by American security specialist Nick Shaw.
It is a tool for any Windows OS (XP, Vista, 7, 8, and 8.1). The tool will lock any Windows operating system to prevent infection from Cryptolocker malware or "ransomware". Due to the way CryptoPrevent works, it really protects against too many malicious softwares, not just from Cryptolocker
2. HitmanPro.Alert, a free tool that will help protect your computer from CryptoLocker ransomware malware.
HitmanPro.Alert includes a new feature, called CryptoGuard, and monitors your file system for any suspicious activity. When it detects suspicious behavior, it eliminates malicious code and your files remain secure.
3. BitDefender Anti-CryptoBlocker, an encryption blocking tool that can detect and block malware.
