How to remove MAAS ransomware (Virus Removal Guide)

Your Service Partner

If you cannot open your images, documents, or files and they have a maas extension, then your computer is infected with ransomware.

The MAAS ransomware is a malicious program that encrypts the personal documents found on the victim’s computer with the “.maas” extension, 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.

What is the MAAS ransomware?

MAAS is a file-encrypting ransomware infection that restricts access to data (documents, images, videos) by encrypting files with the “.maas” 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.

When you are first infected with the MAAS ransomware it will scan your computer for images, videos, and important productivity documents and files such as .doc, .docx, .xls, .pdf. When these files are detected, the ransomware will encrypt them and change their extension to “.maas”, so that you are no longer able to be open them.

Once the MAAS ransomware has encrypted the files on your computer, it will display the “_readme.txt” file that contains the ransom note and instructions on how to contact the authors of this ransomware. The victims of this ransomware will be asked to contact the cybercriminals via the helpmanager@mail.ch and restoremanager@firemail.cc email addresses.

This is the ransom note that the MAAS ransomware will show to its victims:

How did the MAAS ransomware get on my computer?

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

Here’s how the MAAS ransomware might get on your computer:

  • 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 MAAS ransomware.
  • The MAAS ransomware was also observed attacking victims by exploiting vulnerabilities in the program installed on the computer or the operating system itself. Commonly exploited software includes the operating system itself, browsers, Microsoft Office, and third-party applications.

Remove the MAAS ransomware and recover the files

It’s important to understand that by starting the removal process you risk losing your files, as we cannot guarantee that you will be able to recover them. Your files may be permanently compromised when trying to remove this infection or trying to recover the encrypted documents. We cannot be held responsible for losing your files or documents during this removal process.

STEP 4: Restore the files encrypted by the MAAS ransomware

Unfortunately, in most cases, it’s not possible to recover the files encrypted by the MAAS ransomware because the private key which is needed to unlock the encrypted files is only available through the cybercriminals. However, below we’ve listed two options you can use to try and recover your files. Make sure you remove the malware from your system first, otherwise, it will repeatedly lock your system or encrypt files.

Option 1: Use Emsisoft Decryptor for STOP Djvu to restore the files

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. Follow the below guide to recover your files using the Emsisoft Decryptor for STOP Djvu.

  1. Download Emsisoft Decryptor for STOP Djvu You can download Emsisoft Decryptor for STOP Djvu by clicking the link below. Emsisoft logoEMSISOFT DECRYPTOR FOR STOP DJVU DOWNLOAD LINK

  2. Run Emsisoft Decryptor for STOP Djvu When Emsisoft Decryptor for STOP Djvu has finished downloading, double-click on “decrypt_STOPDjvu.exe” to run this program on your computer. In most cases, downloaded files are saved to the Downloads folder. Double-click on the Emsisoft Decryptor for STOP Djvu icon You may be presented with a User Account Control pop-up asking if you want to allow Emsisoft to make changes to your device. If this happens, you should click “Yes” to continue with the installation.

  5. The decryptor will inform you once the decryption process is finished. If you require the report for your personal records, you can save it by clicking the “Save log” button. If your system was compromised through the Windows Remote Desktop feature, we also recommend changing all passwords of all users that are allowed to login remotely and check the local user accounts for additional accounts the attacker might have added.

If the “Emsisoft Decryptor for STOP Djvu” can’t decrypt your documents and you do not plan on paying the ransom, it is advised that you make an image of the encrypted drives so that you can possibly decrypt them in the future.

Option 2: Search for a MAAS ransomware decryption tool

Your computer should now be free of the MAAS 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.
