For example, a file named “sample.jpg” will appear as “sample.jpg.mmdt”.  Victims will need decryption tools and private keys to regain access to such files. Cybercriminals demand huge ransom money in BitCoin (cryptocurrency) to provide those tools.

After Mmdt File Virus attack, victims cannot access their documents, pictures, videos, audio, archives, databases, backups, and more. This virus places a ransom note “_readme.txt” on the desktop and in compromised folders to demand ransom from users. This guide is aimed to help you remove this virus and restore your files without paying money to ransomware creators.

Mmdt Ransomware Overview

Mmdt File Virus is a dangerous threat that blackmails innocent users by taking their files hostage. It uses a powerful encryption algorithm to restrict access to your personal data. As mentioned above, it is a part of STOP/Djvu family and unfortunately, it is not decryptable. Victims are advised to remove the infection and explore data recovery alternatives other than paying ransom fees.

Creators of this threat advise victims to purchase the decryption tool and unique key. They launch a new variant almost every week, making it difficult to find a permanent solution. It will keep encrypting new files until you remove this threat completely from your PC. Removing this threat will not restore your files, but it will prevent further damage. You cannot recover data from backup until you get rid of this infection.

We strongly advise you not to make any contact with attackers. They will try to convenience you to pay the ransom money without even trying alternate methods. Cyber criminals also suggest that trying anything will completely destroy your files and you will never be able to recover your data. They might also send more threats to infect your other devices.

How does Ransomware operate?

When your computer gets infected by ransomware, your access to your files is ceased immediately. It is the primary work of any file-encrypting malware. This is a scare technique used by cyber criminals to create Panic among victims.

Users normally lose their mind when they suddenly lose access to all of their important files and documents all at once. When a ransomware threat gets into your PC, it does not cause any alarms or errors. It silently scans your entire system and then encrypts all of your data once.

Then it will strategically place the ransom notes on your computer where you can easily notice them. Some threats place notes in text format, some as pop-up windows, and some even change the desktop wallpaper. This particular Mmdt virus is a strain of Stop/Djvu family and it places ransom notes in text format in all the compromised folders.

After notifying victims’ about the encryption, attackers force them to pay the ransom money quickly. This is why note contains threatening messages, and offers. This virus offers a 50% discount on ransom price to victims who pay within 72 hours.

Ransomware threats might also offer free decryption of some of the files as proof. It is another technique to get victims to establish communication with cybercriminals. Once the negotiations start, they easily lure in innocent users to pay the money by using various threats.

How does Ransomware spread?

Creators of threats like Mmdt Virus use various methods to spread their creation. Spam emails are one of the most used methods to target innocent users. Emails containing malicious attachments and links are used as carriers to distribute harmful threats. When you get an email from an unknown person or organization that carries some attachments, do not open them.  Do not click on links without verifying the sender and always scan attached files before opening.

Mmdt File Virus can also get distributed via bundled freeware downloads and Peer-to-Peer sharing networks. Cracked software or illegal patches (activation tools) and fake software updates are also used to spread infections. Visiting porn or torrent sites can also expose your system to lots of unwanted threats and viruses.

Do Not Pay Ransom to Mmdt Virus

The note left by the Mmdt Ransomware says that the price of the decryptor is set to $980 USD in Bitcoins. But there is bait too. Virus creators are offering a 50% discount to victims who are willing to pay within 72 hours. So if the user agrees to pay during the first 72 hours of the infection, the ransom fee will be $490USD.

It is a trick used by cybercriminals to force their victims to pay money quickly without seeking advice from anyone else. In most cases, it is hard to restore files without a decryption key but it is also not guaranteed that you will get that after paying.

We advise our readers not to trust the attackers. It is all a scam and they are only interested in money. You cannot trace Bitcoin payments and it is also not reversible. So in case of fraud, you will lose both your money and the data.  Stop/Djvu variants are also known to leave Trojans behind to steal users’ personal and financial information. It is also used to open backdoors through which the next variant can attack your PC again.
