“YOUR FILES ARE ENCRYPTED!

Your documents, photos, databases, save games and other important data was encrypted.
Data recovery the necessary decryption tool. To get the decryption tool, should send an email to:

rebushelp@airmail.cc or rebushelp@protonmail.com

In the proof we have decryption tool, you can send us 1 file for test decryption.
Next, you need to pay for the decryption tool.
In response letter You will receive the address of Bitcoin wallet which you need to perform the transfer of funds.

As you can see, authors of Rebus virus use three contact email address for communication for victims that are willing to pay the ransom:

  • rebushelp@airmail.cc
  • rebushelp@protonmail.com
  • rebushelper@exploit.im

However, we do not recommend using any of them. Cybercriminals can disappear and ignore their victims. According to security specialists at Utanvirus.se[1] you should not contact them in any way because they might blackmail into paying more money or threaten to delete or publish online encrypted personal files.

We highly suggest you remove Rebus ransomware as soon as you can from your computer. This helps to avoid any bigger damage ransomware can make. Do not believe that virus developers are only ones that can decrypt your files. This might be not true, often the virus developer themselves can not decrypt your data. However, third-party tools might help to rescue at least some of lost data, but first, you need to get rid of this cyber threat.

Rebus ransomware removal is difficult because a virus may have installed other malicious components that negatively affect computer's performance and security. For this reason, you need to use professional security software to clean the device. ReimageIntego can help you with this task. You can find detailed instructions at the end of this article. Rebus ransomware virusRebus ransomware encrypts your files and makes them useless. Be aware of the threats behind suspicious emails

Spam email[2] attachments are often used in ransomware distribution. In some cases, these fraudulent emails are hard to recognize because crooks use names of well-known companies. However, there's still a chance to spot dangers in your inbox:

  • if the email arrived in the spam folder, it should not be trusted. Legit company emails do not end up in this box;
  • the letter is sent from never before seen address;
  • attachments make no sense together with letter information;
  • addresses seem legit, but you do not use any of the platforms or providers;
  • the body of the letter is empty, but it includes an attachment only.

Delete spam emails immediately and do not open them. They might contain Trojan[3] viruses or malware executable. As you can see only one tiny mistake can lead to the horrible consequence.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
