Rote ransomware removal instructions

If you cannot open your images, documents, or files and they have a “.rote” extension, then your computer is infected with the STOP/DJVU ransomware.

The STOP/DJVU ransomware encrypts the personal documents found on the victim’s computer, then displays a message which offers to decrypt the data if payment in Bitcoin is made. The instructions are placed on the victim’s desktop in the _readme.txt file.

1. What is the Rote ransomware?

Rote is a file-encrypting ransomware infection that restricts access to data (files, images, videos) by encrypting files with the “.rote” extension. It then attempts to extort money from victims by asking for “ransom”, in the form of Bitcoin cryptocurrency, in exchange for access to data.

This ransomware targets all versions of Windows including Windows 7, Windows 8.1 and Windows 10. When this ransomware is first installed on a computer it will create a random named executable in the %AppData% or %LocalAppData% folder. This executable will be launched and begin to scan all the drive letters on your computer for data files to encrypt.

STOP/DJVU ransomware searches for files with certain file extensions to encrypt. The files it encrypts include important productivity documents and files such as .doc, .docx, .xls, .pdf, among others. When these files are detected, this infection will change the extension to Rote, so they are no longer able to be opened.

The STOP/DJVU ransomware changes the name of each encrypted file to the following format: name.rote

Once your files are encrypted with the “.rote” extension, you cannot open these files and this ransomware will create the info.txt ransom note in each folder that a file has been encrypted and on the Windows desktop.
When the infection has finished scanning your computer it will also delete all of the Shadow Volume Copies that are on the affected computer. It does this so that you cannot use the shadow volume copies to restore your encrypted files.

2. How did the Rote ransomware get on my computer?

The Rote ransomware is distributed via spam email containing infected attachments or by exploiting vulnerabilities in the operating system and installed programs.

Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link inside the email). And with that, your computer is infected with the Rote ransomware.

This ransomware was also observed attacking victims by hacking open Remote Desktop Services (RDP) ports. The attackers scan for the systems running RDP and then attempt to brute force the password for the systems.

3. Is my computer infected with Rote Ransomware?

Here is a short summary for the Rote ransomware:

  • Ransomware family: STOP/DJVU ransomware
  • Extensions: .rote
  • Ransomware note: _readme.txt
  • Ransom: From $490 to $980 (in Bitcoins)
  • Contact: restorefiles@firemail.cc or gorentos@bitmessage.ch
  • Symptoms: Your files have a .rote extension and cannot be opened by any programs

When this ransomware infects your computer it will scan all the drive letters for targeted file types, encrypt them, and then append the “.rote” extension to them. Once these files are encrypted, they will no longer able to be opened by your normal programs. When this ransomware has finished encrypting the victim’s files, it will also display a ransom note that includes instructions on how to contact these cybercriminals (restorefiles@firemail.cc or gorentos@bitmessage.ch).

This is the message that the Rote ransomware (_readme.txt) will display:

4. How to remove the Rote ransomware and recover the files

STEP 3: Restore the files encrypted by Rote ransomware with Emsisoft Decryptor for STOP Djvu

However, if your files were encrypted with an offline key there is a chance you can recover them by using Emsisoft Decryptor for STOP Djvu decryption tool.
Here’s how to recover your files using the Emsisoft Decryptor for STOP Djvu.

Make sure you remove the malware from your system first, otherwise, it will repeatedly lock your system or encrypt files.

  1. Download Emsisoft Decryptor for STOP Djvu

Do not pay any money to recover your files. Even if you were to pay the ransom, there is no guarantee that you will regain access to your files.

Your computer should now be free of the Rote ransomware infection. If your current antivirus allowed this malicious program on your computer, you may want to consider purchasing the full-featured version of Malwarebytes Anti-Malware to protect against these types of threats in the future.
