Odveta Ransomware

Odveta Ransomware appears to be a threat from the Ouroboros Ransomware family. Some of the malicious applications belonging to it are decryptable, but not this one. The malware encrypts various user data with a robust encryption algorithm and shows a ransom note that demands to pay for decryption. To make sure a user is less likely to be able to restore files on his own, the malicious application’s developers programmed it to erase shadow copies too. Even so, we recommend against putting up with their demands if you do not want to risk losing your money in vain. If you have backup copies, you could replace encrypted files with them instead of trying to get decryption tools from cybercriminals. Of course, before uploading backup copies or creating new data, we recommend removing Odveta Ransomware just to be safe.

Further, in this article, you can learn more about the malicious application’s working manner and its deletion. However, the first thing we would like to explain is how Odveta Ransomware could be spread. Our researchers say that the malware might be distributed with Spam emails. A lot of similar threats travel this way. Also, many of them are disguised to make them look like harmless files and trick victims into thinking that it is safe to open them. Sadly, if launched, threats like Odveta Ransomware can settle in without a user noticing anything. Thus, it is crucial to scan all files coming from questionable sources even if they do not look dangerous. We also recommend scanning data downloaded from unreliable file-sharing websites as such sites can also contain various threats in disguise.

If Odveta Ransomware is launched, it should create a copy of its launcher in the %APPDATA%\Microsoft\Windows\Start menu\Programs\Startup directory. Also, the malicious application ought to delete all shadow copies to make sure its victims cannot restore the files that the malware might be about to encipher. Our researchers say that each encrypted file should receive a second extension called .odveta, for example, forest.jpg.odveta or ticket.pdf.odveta. The next thing Odveta Ransomware should do is create a document called Unlock-Files.txt. Copies of it might be scattered among directories that contain encrypted files. Inside of this text file, users should find a message saying: “All Your Files Has Been Locked They Cant Get Restore or Decrypted Without Decryption Key + Tool.” It should also describe how a user could purchase the mentioned decryption tools and how to contact the malware’s creators to learn how to make a payment to their account.

Moreover, it is specified that the ransom ought to be paid in cryptocurrencies like Bitcoin. To convince victims to pay the note may also suggest sending some data for free decryption. If you get a few of your files decrypted, it will only prove that hackers have the needed decryption tools, but not that they will send them to you. Even if you pay a ransom, hackers may not bother sending you the promised tools, or they could ask for more money. Therefore, we recommend not to rush and consider the offer in the Odveta Ransomware’s message carefully.

If you decide you do not want to risk getting scammed, we advise not to pay the ransom. Even though your shadow copies might be destroyed, you could still restore encrypted files while using backup copies from removable media devices or cloud storage. As said earlier, to be safe, it is advisable to remove Odveta Ransomware before transferring backup copies or creating new files. There are a couple of ways to delete this threat. The first one is to erase its launcher and its copy manually. This task might not be easy, which is why we provide deletion instructions at the end of this paragraph. The second option is to employ a reputable antimalware tool and perform a full system scan. Once the chosen tool finishes scanning your device, you should be able to eliminate Odveta Ransomware and other detections by clicking its provided removal button.
