Computer infections like the Mmvb ransomware are more dangerous than usual Trojan infiltration. In addition to infecting the system, the Mmvb ransomware also targets the important files of computer users. Its major objective is to implement a challenging encryption to render the files unusable. At the same time, this malware will add the mmvb file extension. To give an example, following the encryption procedure, the regular photo.jpg will become photo.jpg.mmvb.
How Mmvb infects the computer?
Usually, infected emails sent from an attacker’s server have the Mmvb ransomware virus, which computer users can get from them. However, because it is presented as a legitimate message from a reputable institution, recipients may never realize it for what it is. Because the linked Mmvb ransomware file has the official Word or Excel symbol, attackers have also ensured that it would seem as a regular document file.
Another method of spreading the Mmvb ransomware has been observed: installing cracked software. Either the installation file or the included serial key generator includes the malware. The Mmvb ransomware readily starts up when the computer user runs the setup process because it is already in executable format.
The propagation of the Mmvb ransomware is further aided by a deceptive advertising campaign that promotes software updates. Typically, when accessing dubious websites, especially those involved in the illicit distribution of copyrighted content, dangerous pop-up adverts appear. The advertisement claims to have discovered outdated software on the machine. It suggests downloading the suggested software update to resolve the problem for online users. But Mmvb ransomware will be launched in place of a software update.
Mmvb file encryption and decryption
The majority of the files are encrypted by the Mmvb virus once it has been run, however system data, program files, and the virus executable are left unaffected. To render the data unreadable, this attack employs extremely sophisticated encryption techniques. Likewise, the file extension Mmvb is added to encrypted files. The ransom note _readme.txt generated by the Mmvb ransomware contains information about the current attack. The document’s content also contains instructions on how victims can recover all Mmvb infected files and decrypt their encrypted data. An excerpt of the ransom note is provided below.
| Threat Name | Mmvb Ransomware, STOP, DJVU |
|---|---|
| Threat Type | Crypto-virus, File Locker, Encryption Virus |
| File Extension | .mmvb |
| Ransom Amount | $480 – $980 |
| Ransomware Note File | _readme.txt |
| Attacker’s email | support@bestyourmail.ch datarestorehelp@airmail.cc |
Backup your files
One important step before proceeding with the procedures below is to backup your files. Ransomware are not the same. Each has its unique sets of payloads aside from encrypting the files with complex method. Others tend to delete the infected files after certain period, while others keep them concealed on hidden places. In addition, ransomware decryption tools are not guaranteed to be perfect, there are instances that files suffer from damages during the decryption process.
So, create a backup copy of your entire Mmvb encrypted files right now.
