Nemesis Ransomware Virus (Removal Steps and Protection Updates)

The Nemesis ransomware is a new type of encrypting malware that uses the AES cipher to compromise valuable user data and extort the victims for a ransom payment. Our removal guide will show you how you can remove the existing infection from your computer and protect yourself in the future.

Nemesis Ransomware Description

Nemesis ransomware shares the same ransomware family as CryptON and X3M crypto viruses. It uses the typical infection patterns of a data locker ransomware by activating its encryption engine upon infection.

Once the malicious Nemesis ransomware payloads are on the computer, it initiates the infection process. The ransomware ensures its sustainable presence on the PC by creating files and accessing different system libraries that allow it to perform various functions. The Nemesis ransomware associated files may plague essential Windows OS folders like:

  • %AppData%
  • %Windows%
  • %Local%
  • %Roaming%

Afterward, it initiates scanning process and encrypts all files set as its target utilizing the AES-256 encryption algorithm. The encrypted files may be marked with malicious extensions that include hackers’ email and four or five randomly generated symbols at the end like .v8dp, .63vc4, etc. Viruses like this one usually target commonly used and important file types – various multimedia files (audio, video, and photos), backup images, configuration files, office documents and more.

Nemesis is also able to connect its remote command and control server to transfer the decryption key so that only crooks possess it and blackmail victims for a ransom payment. So after the encryption process, the threat is designed to drop a ransom note in a file called “### DECRYPT MY FILES ###.html” that is automatically displayed on the victim’s screen. The text is encouraging victims to pay the ransom for the decryption key and all it could read is:

The latest reports about the Nemesis ransomware reveal that the threat is likely to have a new variant that uses a long extension that contains several random hexadecimal characters and the .onion.to._ malicious extension at the end of the file name. Security researchers are currently investigating the ransomware samples so our advice is to save your encrypted data and wait for a possible breakthrough. Meanwhile, some alternative data recovery solutions may be of help to restore critical data – look at step six in the removal guide at the end.

Nemesis Ransomware Distribution

The first Nemesis ransomware infections were reported by victims on January 8. It is not known which infection method is primarily used by its operators, however, we can assume that spam email campaigns and infected software bundles, as well as updates and games downloaded from hacked or malicious sites or BitTorrent peers, may be the primary medium.

It appears that Nemesis ransomware primarily targets English-speaking users.
