What is Ooss Ransomware?
If your operating system is protected, Ooss Ransomware should not be able to sneak in. However, if you do not use protection tools, and if you are relying on your own ability to identify and remove malware before it is executed, it is unlikely that you will stand a chance of stopping this threat before it encrypts your personal files. Anti-Spyware-101.com researchers warn that this malware uses very sneaky ways to invade your operating system, and you are always involved in the process. For example, the infection’s launcher could be introduced via a bundled downloader as a helpful application. If you are tricked into executing this bundle, the ransomware slithers in immediately. In a different scenario, the launcher could be introduced via spam email as a document/PDF file that, allegedly, represents flight information, hotel reservation, postage delivery details, etc. If you open this file, the ransomware executes. After that, the only thing you can do is delete Ooss Ransomware.
How does Ooss Ransomware work?
Before you even realize what has happened, Ooss Ransomware should encrypt your personal files. That means that your documents and photos are modified. During encryption, plain text is translated into ciphertext, and that is why you cannot read your files anymore. To help you figure out which files were corrupted faster, the infection also adds the “.ooss” extension to their names. This is exactly how Nppp Ransomware, Righ Ransomware, Remk Ransomware, and tons of other infections work as well. While there are thousands upon thousands of file-encrypting threats in the world, the listed threats are part of the STOP Ransomware family. They all were created using the same malware code, and that is why they are practically identical. Even the files created by every single one of these infections and the content inside these files is always the same. Of course, a file named “PersonalID.txt” (in %HOMEDRIVE%\SystemID) has a unique identification code every single time. Also, the ransom note file, “_readme.txt” (in %HOMEDRIVE%) might represent unique email addresses. But that is not always the case.
The ransom note represented by Ooss Ransomware asks to send a message to helpdatarestore@firemail.cc or helpmanager@mail.ch. These email addresses have been listed in the ransom notes of Nppp Ransomware, Lokd Ransomware, Rezm Ransomware, and several other threats. That indicates that the same attackers stand behind them all. For all we know, the same attackers could be responsible for all STOP Ransomware variants. If you email the attackers, they will provide you with instructions on how to pay a ransom of $490 in return for a decryptor. The problem is that even if you follow these instructions to a T, you are unlikely to obtain the decryptor, and that is because the attackers do not need to give it to you. Who’s going to force them? What we hope for is that you have other ways to get the files corrupted by Ooss Ransomware back. For example, did you know about a tool called “Stop Decryptor.” It is free, and it is meant to restore the files corrupted by the infections from the STOP Ransomware family. Alternatively, you might be able to use backup copies to replace the corrupted files.
