C0hen Locker Ransomware Removal Guide

Do you know what C0hen Locker Ransomware is?

C0hen Locker Ransomware is a malware that encrypts files only in specific directories that we will list in this article. After encryption, locked files should receive the .c0hen extension. Also, they should become unreadable, which means your computer should be unable to recognize and launch them. Usually, encrypted files can be decrypted, but only with decryption tools that the malicious application’s developers might have. The creators of this threat offer purchasing them for a particular sum, which we do not recommend paying if you do not want to risk losing your money for nothing. After all, there are no reassurances that you will get the promised decryption tools. Consequently, we recommend considering the cybercriminals’ offer carefully. Also, we advise not to leave the malware unattended. You could try to delete C0hen Locker Ransomware with the removal guide placed below or a reputable antimalware tool of your choice.

Threats like C0hen Locker Ransomware can enter systems by exploiting vulnerabilities like unsecured RDP (Remote Desktop Protocol) connections. Consequently, users who wish to avoid similar threats should make sure that their systems would not have such weaknesses. Moreover, cybercriminals also use various tricks to convince victims to launch the malware themselves without realizing it. For example, they may send you an email saying that you should view the file attached to it. To convince you to do it, hackers can pretend to be someone you would not question like a reputable company or your client, etc. Therefore, instead of opening data received via email, we recommend scanning it with a reliable antimalware tool even if it does not look suspicious or dangerous to you. It would be smart to do the same to all files coming from unreliable sources, such as file-sharing websites.C0hen Locker Ransomware Removal GuideC0hen Locker Ransomware screenshot

C0hen Locker Ransomware settles in by creating a Registry entry that disables Task Manager and an entry that makes the infected computer relaunch the malicious application after a restart. Next, the malware should start encrypting files in the Desktop, Downloads, Documents, Music, Pictures, Videos, Recent, and Favorites folders located in the %USERPROFILE% directory. Files located in other folders should not be encrypted. What we ought to stress is that the threat might start encrypting more files if a new version gets released. As you see, encrypting data in the listed directories may not be enough to make a user desperate and convince him to pay for decryption. Thus, it is likely that this could be just a test version. In any case, you can see which file are encrypted and which are not by checking if they are marked with the threat’s extension (e.g., picture.jpg.c0hen).

After encryption, C0hen Locker Ransomware should open a window with a ransom note. It might say that you need to pay 0.15 Bitcoins in exchange for decryption tools.

We do not recommend paying because there is always a chance that hackers could scam you.

What we do advise is not to leave such a malicious application on your system, especially when it can restart with the operating system and possibly encrypt new files.

In non-techie terms:
