What is Parasite ransomware?

Parasite ransomware – a file-locking virus that exploits its victims for monetary gain

Parasite ransomwareA data-locking computer infection that locks all data with RSA-2048 cipher

It is a computer virus that encrypts personal victim data with military-grade RSA-2048[1] and RC4[2] encoding algorithms. It demands payment in cryptocurrency Bitcoins (through @READ_ME_FILE_ENCRYPTED@.html ransom note) for said file decryption.

The virus also renames all files by appending the .parasite extension – this is where malware gets its name from. Data is inaccessible until a required decryption tool is used. Unfortunately, it's tough to do without the help of the cybercriminals who would prefer to be contacted via this email –

If any of your devices were affected by this file-locking malware, then you chose the right place to learn more about it and find out how to remove it. This article contains information about the Parasite virus, including distribution techniques used to deliver it and its removal options.

All ransomware generates some sort of ransom notes when the encryption of data is completed. With some, it might be text files (Wbxd virus, Cring virus), while others (Dis virus), in addition to text files, can create pop-up windows too. This ransomware, however, creates an .HTML file ransom note.

Within it, cybercriminals explain what happened to the victim files and what they should do to restore them. The main goal of these notes is to scare or convince victims into meeting the demands of their assailants. Developers of Parasite virus want to be contacted via a given email so they could provide ransom details because apart from the preferred payment method, the ransom amount isn't specified.

The whole message from the cyber thieves is long and can be read here:

Although it might seem that meeting the criminals' demands is the easiest way out of this sticky situation, it's the worse thing any ransomware victims can do. And here's why:

  • Received money motivates the criminals to increase their attacks.
  • It finances their development of more sophisticated malware.
  • It provides funds for research of more efficient ways of payload file delivery.

Parasite ransomware virusA type of virus that uses extortion for monetization purposes

The only way to stop ransomware creators from infecting the computers of innocent people is by not paying them. If victims stopped succumbing to their assailants, new file-locking parasites wouldn't be created, and hopefully, the attacks would stop.

That's why our cybersecurity team highly recommends victims remove ransomware from their infected devices. Best results are achieved when doing that with a professional anti-malware tool such as SpyHunter 5Combo Cleaner or Malwarebytes. Scan your entire system and let the software do the rest.

Malware usually makes changes to system files and system settings. That could lead to various system issues, such as freezing, crashing, etc. So once Parasite ransomware removal is finished, experts[3] recommend performing a system repair with powerful system tune-up tools like FortectIntego or similar.

Learn to identify spam emails to avoid ransomware

We've all received spam emails in our lives, but little did you know that ransomware developers love to spread their creations through them. The infections are usually hidden either as an email attachment or in a hyperlink. These emails might look like legitimate letters from your beloved store, bank, shipping company, etc.

But as soon as any of the aforementioned options are clicked, your device's files might be locked within minutes. Our team compiled a set of signs that would help everyday computer users to identify these threats. Please don't open any email attachments or hyperlinks if an email consists of any of these indications:

  • You're addressed in a general manner, instead of your full name.
  • You are urged to visit a site through a given hyperlink immediately.
  • The email is written in poor grammar.
  • The sender's domain doesn't exactly match the domain of the company.
  • You're pushed to download the attachment because it contains some critical updates/data.
  • Email senders ask to provide them sensitive information.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
