What is Nemesis Ransomware?
Nemesis Ransomware is a newcomer in one of the most dangerous segment of malware infections. This ransomware is mostly attacking vulnerable servers of corporations that may have the financial background to pay the demanded ransom fee for the decryption of their precious files. This major hit encrypts all important files, including documents and databases, which could be devastating for a hospital or any company storing large amounts of client data, not to mention sensitive information. Although it may seem as the only option for you to transfer the ransom fee, we must warn you that it is always risky. It is one thing that cyber criminals may not even consider sending you the decryptor software, but there could be technical issues emerging, too. What if these crooks need to shut down the Command and Control server? This could mean that your unique decryption key would be lost so you could do nothing even if you had the software. We always recommend that you remove the ransomware that has hit you; however, in this particular case we do not say so. The reason is simple: There is no need to delete Nemesis Ransomware because it does it automatically when its vicious job is done.
Where does Nemesis Ransomware come from?
Normally, ransomware infections are spread either via spam e-mails as malicious attachments or via malicious websites created with Exploit Kits (e.g., Angler and Rig). In both cases, you could avoid such a dangerous attack if you are more careful. For example, you should never open a questionable e-mail that comes from an unknown or unfamiliar sender with a subject that you doubt is concerning you. Such a spam has an attachment that you are led to believe that it is important for you to view. However, running this attached file that may seem to be an image, a video, or a document, would initiate the devastating attack. Removing the ransomware after this cannot save your files from being encrypted but you do not have any other choice either, if you want to keep on using your PC. In the case of Exploit Kits, you need to be careful with your clicks because by clicking on unsafe third-party ads and links you can be redirected to malicious pages containing Exploit Kits. This simply means that as soon as your browser loads such a page, a ransomware infection may be dropped without your noticing it. Keeping all your browsers and drivers updated could be one of the solutions for you to be safe from this kind of attack.
Nonetheless, our malware specialists at anti-spyware-101.com have found that this infection is more like Parisher Ransomware and Esmeralda Ransomware with regard to its distribution method because Nemesis Ransomware also exploits RDP (Remote Desktop Protocol) vulnerabilities to infect servers and systems. It is possible that these cyber crooks scam you first to make you reveal your credentials, such as user names and passwords through social engineering. And then, they can easily gain access to your server through remote desktop software (e.g., TeamViewer). But criminals may also use brute force attacks, which could take a while longer though. Once they can find a way to your server, which may not be up-to-date and secured with a strong password, they can manually infect you with this ransomware and you would not even see it coming. As a matter of fact, you will not even see this infection going either as it removes itself after the attack; this is why you do not even need to delete Nemesis Ransomware.
How does Nemesis Ransomware work?
Our malware specialists say that this ransomware program targets your main files, including your photos, documents, and databases, and encrypts them with the AES-256 algorithm, which is a built-in function in your Windows Operating System. For this reason, the attack could take less than a minute; clearly, depending on the number of files affected and the parameters of your PC. The names of the affected files are modified and append a “.v8dp” extension. After the encryption is finished, the ransom note image comes up on your screen above all the other active windows so that you cannot miss it. As a matter of fact, this note seems identical to that of X3M Ransomware; however, we have not found any other traits matching. Therefore, we cannot claim that these infections have anything to do with each other; this could be a simple copy of the note.
This note claims that your files have been encrypted and you have to pay a ransom fee to purchase the Nemesis decryptor tool. This fee could be as high as 10 Bitcoins, which is around 9,222 dollars. Most likely, few individual computer users would have this kind of financial background to pay for their files. This is why we suppose that mostly bigger corporations are targeted by this dangerous ransomware infection. Once the transfer is done, you have to send an e-mail to “firstname.lastname@example.org” or contact these crooks via bitmsg.me.
How can I delete Nemesis Ransomware?
As we have already stated, this ransomware actually removes itself so you do not need to do anything to delete Nemesis Ransomware from your system. It goes as silently as it comes; only, it leaves a trace of encrypted files behind. Since there is no free tool yet on the web that could possible recover your files, it seems that there is no chance for you to save your files unless you have a backup on a portable drive or you are ready to risk transferring the ransom fee. Let us remind you that sending money to such criminals is tantamount to supporting them to commit further online crimes. If you want to defend your system from future malicious attacks, we suggest that you install a reliable anti-malware application as soon as possible.
