Koko Ransomware

What is Koko Ransomware?

When Koko Ransomware encrypts your photos, documents, and other personal and sensitive files, it changes the data of these files, and they can be read only when a special decryptor is used. That is the strength of this malicious threat because if the victim cannot restore the files or replace them with backups, they might be tricked into paying money for the decryptor proposed by the attackers. Anti-Spyware-101.com research team has analyzed thousands of file-encrypting infections, and if they have one thing in common it is that victims do not get to decrypt their files; at least, in most cases. Some of the more recent threats analogous to the ransomware we are discussing in this report include CXK-NMSL Ransomware, Erenahen Ransomware, and Sherminator Ransomware. Hopefully, you have backups, and you do not need to worry about restoring the corrupted files, but, in any case, you need to delete Koko Ransomware, and that is what we are here to help you with.

How does Koko Ransomware work?

Koko Ransomware might spread using spam emails, which happens if the launcher of the infection is executed when the victim opens a harmless-looking link or attachment. It could also be spread via a software bundle along with less or more harmful infections. If that is the case, once you scan your system, you will know if you need to delete any additional threats. Koko Ransomware could also be dropped if cybercriminals learn about security vulnerabilities within your system and then successfully exploit them without you even knowing about it. Regardless of how it gets in, once it is in, the encryption begins. 859 types of files can be encrypted, including .DOC, .PDF, .JPG, .MP3, .AVI, and many others. While you can check which files were encrypted by trying to open them one by one, all you really need to do is look for the “.mailto[kokoklock@cock.li].{unique ID}” extension appended to their names. If you check the corrupted files and see that you have backups, remove them without hesitation, and then move on to the removal of the malicious infection itself.

If backups do not exist, and the files encrypted in the %USERPROFILE% and %HOMEDRIVE% directories do not have copies, you might consider following the instructions represented via the “{unique code}-Readme.txt” file. According to the note inside, if you send a message – which should include a unique code – to cyber attackers using kokoklock@cock.li or pabpabtab@tuta.io, they could help you recover your files. Of course, that is not what you should expect from them. Instead, they would demand money from you, and if you believe that they would keep their word and provide you with a decryptor afterward, you must not have encountered cybercriminals before. They can deceive you and feed you lies just so that their goals would be met. Hopefully, you have not been tricked into contacting the attackers behind Koko Ransomware, and you still have time to figure out what you want to do. Of course, we recommend focusing on the removal of this dangerous infection.
