Frogo Ransomware is the malicious infection that is responsible for renaming your personal files, adding the “.frogo” extension, and also making them unreadable. This infection uses a unique encryptor to lock your files, and so you cannot read them, unless you have a fitting decryptor. At the time of research, we could not confirm whether a free decryptor existed, but we certainly do not think that victims of this malware should rely on the decryptor offered by the cybercriminals who created the infection itself. If you have followed their instructions and paid the ransom in return for a decryptor already, it is most likely that you did not receive the decryptor you were promised, and now you have less money too. While removing Frogo Ransomware does not solve the issue of file decryption, this malicious threat needs to be eliminated as soon as possible. First, read the report to understand the infection better, and then choose one of the discussed options to delete it quickly.
According to our malware researchers, Frogo Ransomware is part of the Amnesia family, to which Amnesia Ransomware and Amnesia2 Ransomware belong to as well. Free tools named ‘Amnesia Decryptor’ and ‘Amnesia2 Decryptor’ exist, and so perhaps we will see a free decryptor created for the victims of Frogo Ransomware specifically as well. For the time being, it appears that they can employ the Amnesia Decryptor. If you believe that you have found a different tool that can restore your files, make sure that you research it first because you do not want to let in additional malware or waste money on useless services. If a legitimate decryptor somehow does not work for you, you might be able to rely on your own backups to replace the files corrupted by this dangerous malware. Note that there are literally thousands of file-encrypting infections, and so you need to protect your files against them all. It appears that creating copies and storing them somewhere safe is the best method of protection. Without a doubt, you also want to implement reliable security software to guard your operating system.
If your Windows operating system is not guarded, Frogo Ransomware has a much easier time slithering in, which it is likely to do with the help of RDP vulnerabilities and spam emails. If this malware executes silently, it should drop an .exe file in %APPDATA% and then start the encryption of your personal files. As we mentioned already, files are renamed, and random combinations of letters, numbers, and symbols are used. Once that is done, Frogo Ransomware deletes itself from %APPDATA%, but only after a file named “HOW TO RECOVER ENCRYPTED FILES.TXT” is dropped to every affected folder. This file represents the message from the attackers, and they want you to think that you need to obtain their decryptor to recover all encrypted files. To obtain it, you are supposed to email email@example.com. After this, you have 90 hours to pay a ransom or have your files deleted completely. As we mentioned already, it is unlikely that you would obtain a decryptor by communicating with cybercriminals and following their demands, which is why we do not recommend sending emails or paying the ransom.
Hopefully, you can use the free Amnesia decryptor to recover the files corrupted by Frogo Ransomware. If that is not possible, we hope that you can replace the corrupted files with copies stored in secure backup. Before you take on these tasks, you want to delete the infection. While the main .exe file should delete itself automatically after all personal files get encrypted, we would not bet on anything when it comes to malware. Even if you believe that malware is gone, it is a good idea to inspect the operating system to see whether there is anything that requires removal. The manual Frogo Ransomware removal guide below shows where to look for the infection’s leftovers, but even if are able to complete all steps, you still should inspect your system. Of course, in our opinion, the best thing you can do is install a legitimate anti-malware tool that would automatically scan the system, identify threats, perform removal, and of course, reinstate full protection against malware in the future.
