MMM Reborn virus Removal Guide

What is MMM Reborn ransomware?

MMM Reborn ransomware is a cryptovirus that encrypts files using RSA + AES algorithms and demands a ransom to return files

MMM Reborn ransomwareMMM Reborn ransomware is a virus that belongs to a malicious ransomware family and is the renewed version demanding a huge ransom.

MMM Reborn ransomware is the cyber threat that recovered its activity after a year. Surprisingly, this new version of MMM ransomware demands a huge ransom amount – 222BTC that is equivalent to around 800 000 US dollars. This is not a reasonable price, and we do not recommend paying the ransom at all. This is not the solution for data recovery because the alleged decryption key might not even exist and can be used just a trigger to convince the victim that the payment is the only way to recover files. This virus adds .info file extension to encrypted[1] files and then displays the ransom note in the window called IF_YOU_NEED_FILES_READ_ME.html. You can also find this malware by its executable RebornM.exe. MMM Reborn ransomware virus already released a few more versions to the wild. Most of the previous versions in the MMM family use AES and RSA algorithm mix for the file locking and demands at least 0.25 BTC. The latest MMM Reborn ransomware V4 was spotted at the end of March in 2019 and had one distinct feature – ransom of 8 Bitcoin that becomes 12 BTC if you don't pay in 7 days.

MMM Reborn ransomware virus at first seemed to still be in development because the ransom amount demanded from victims was too big for everyday PC users to pay. However, this is the most dangerous type of cyber threats because cybercriminals that are running this malware program focuses on data-locking. So they can get your money.

MMM Reborn ransomware uses RSA 2048 method or doubles that up with AES128 for the main file-locking process. During the encryption, the original file code is altered and, this way, data becomes unusable. When your files get marked with the appendix, you can also see the ransom note IF_YOU_NEED_FILES_READ_ME.html on your computer's screen that additionally, to the payment instructions, displays the following text:

All of your files were encrypted by a strong encryption with RSA2048
Specially for your PC was generated personal RSA2048 Key, both public and private
ALL YOUR FILES were encrypted with the public key, which has been transferred to your PC via the Internet
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our Server

To remove MMM Reborn ransomware properly, you may also need to enter the Safe Mode with Networking, so that the antivirus tool that you use can completely scan the system of your device and no malware is left behind. Also, a great tip is to additionally use FortectIntego or other PC repair programs to double-check for virus damage.

Paying MMM Reborn ransomware ransom shouldn't be an option because it may lead to more problems like permanent data or money loss.[2] There is little to no chance that developers are releasing the decryption key for you after the payment is done.

The newest MMM Reborn ransomware version – V4

MMM Reborn first was spotted back in December of 2018 and seemed to be not true because of the huge ransom amount that goes up to 444 BTC if not paid in less than 3 weeks. However, after a few months of silence developers released a new version to the wild – MMM Reborn V4.

In March 2019 this version came to the attention of researchers with a few new specific features. Firstly, the ransom note in this case delivered in the text file called DECRYPT_FILES.txt as before the message about the attack was shown in an HTML window. Besides the text file with a ransom note, the main executable that launched the script RebornMMM.exe alongside other files like ecorp.bat can be found on the affected system.

TripleM Reborn ransomware v4 ransom note states:

What happened to your files?

The ransom note gives out more information about the particular ransomware attack and informs people that the amount of ransom at first is 8 Bitcoins. However, it may go up to 12 Bitcoins if you decide to wait more than seven days to pay up. Also, the contact email given in the note is the same as the previous version – However, you should know that contacting these criminals cannot give you any positive results.[4] You need to remove TripleM reborn ransomware instead.

Ransomware infections caused by payload carriers hidden in spam email attachments

Any email that is sent from a questionable or unknown source should be more inspected because malicious actors nowadays can make legitimate-looking emails and distribute their products via attached files or links. The main example is when the executable file loads on the system with the direct malware code and spreads the ransomware on your computer or infects the system with trojans designed to further spread malicious programs.

Also, Microsoft Word or Excel files can be used as a disguise for these payload droppers because the common file format encourages users to download and open the mentioned document on the computer. However, the minute you download and open this document your system gets infected with the notorious malware.

You can avoid these instances if you pay more attention to emails you get on a daily bases, especially if the email contains file attachments and files or hyperlinks. You can always try scanning the file before downloading or opening on the machine or delete suspicious emails immediately without consideration.

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.
