Zuahahhah – a new and decryptable family member of the Crypt888 virus

Rasnom note by Zuahahhah ransomware virus

Zuahahhah is a new version of Crypt888 ransomware. However, crooks haven’t improved this crypto-malware enough, so it’s decryptable.[1] Thus, after the infiltration, you should not be tricked by cyber criminals and their threats.

The ransomware’s executable travels as the server.exe file. It is most likely spread as an obfuscated email attachment. However, Zuahahhah virus might also enter the system as a fake or illegal program. Masking helps not only to trick the users but allows bypassing computer’s security too.

As soon as it gets on the affected device, it establishes remote access with its Command and Control (C&C) server. What is more, it might obtain various information about the computer and operating system. However, malware is expected to be capable of tracking information about the user as well. Thus, one of Zuahahhah ransomware components might be spyware.

This cyber threat might also affect legitimate system’s process and inject malicious codes. It might install numerous harmful files or programs that help to complete its malicious tasks. What is more, it might modify Registry and delete particular files.

Of course, the main task of the file-encrypting virus is, obviously, data encryption. It aims at a bunch of popular file types. Following the encryption, it changes computer's desktop with a threatening note. Judging by the informational message left by the cyber criminals, they are not native English speakers. However, victims can understand that their files have been locked by Zuahahhah. As a result, their passwords, emails, and files stored on the computer are in danger.

The ransomware might be capable of deleting encrypted files. Thus, you should not delay Zuahahhah removal and test the patience of the developers. As we have mentioned in the beginning, the virus is decryptable. But first, you should wipe out it from the system.

The major security and antivirus programs detect this virus, so you should not encounter any difficulties with its removal. So, it should not be hard to remove Zuahahhah from the PC. If you do not have any professional security tool installed, you should obtain Reimage. This program cleans your computer from viruses and protects from other cyber threats.

Previous variants of the Crypt888 attacked users in Portugal, Check Republic, Brazil, Italy[2] and other countries. Therefore, Zuahahhah might also be a worldwide problem, so you should be aware of its distribution methods in order to avoid it.

The ways how ransomware viruses spread

Authors of the crypto-malware rarely rely on only one distribution method. They usually take advantage of several strategies in order to attack as many devices as possible. Not only the majority of file-encrypting viruses share similar features, but also they spread similarly. These are the most common ransomware distribution ways:

  • malicious spam emails and their attachments,
  • malvertising,
  • fake/illegal downloads,
  • fake updates,
  • exploit kits.

The biggest chances to get infected with ransomware is click on a malicious email attachment or any other interactive content included in the letter, for instance, link or button. Crooks use social engineering tactics and convince people that the letter is sent from the reliable institution that urges to open the document or check the information provided in particular website.

Therefore, you should be careful with emails and do not forget other security tips,[3] such as download only legal software, install updates from the publisher’s site, avoid visiting high-risk websites and keep programs and OS updated.

Zuahahhah removal must be performed with reputable security software, such as Reimage or Malwarebytes.
