How did the Mmpu ransomware get on my computer?

The Mmpu ransomware spreads by placing websites to get hacked programs or games. Cybercriminals who spread this ransomware are extremely tricky, and aim to stay connected with current things. New games introductions, new popular films – Mmpu creators make everything to get their money on that. One of the most popular tactics these crooks put to use is one-day sites with torrent downloading links. Nonetheless, pursuing the current trends is not the single tactic these crooks utilize. Options that have already turned into classic, such as email spamming, are also normal for STOP/Djvu ransomware distribution.

Malicious email spam
The example of email spamming that may lead to Mmpu ransomware injection

Avoiding this ransomware does not require a lot of effort. Considering the regular rules of PC hygiene will substantially minimize all hazards. Bear in mind that opening all documents you receive on e-mail is not a good option. Even worse scenario is to allow macros in Microsoft Office documents. However, it is much better to avoid the malware attack at the moment when you have only opened the e-mail message. Examining the sender’s address can say a lot about what you can expect, as well as when you see things like “support@amazon.com”– it is likely a trustworthy e-mail. On the other hand, stuff that tries to resemble Amazon or FedEx shipment alert, however, uses the email address of “amazonspurrot1363@gmail.com”– should make you get on the alarm. Above, you can see the illustration of such a message.

Illegal sources of different digital things need some additional explanation. Violating copyright law already throws you to the danger of being fined. Nonetheless, using torrent trackers or third-party websites to download “free” programs also exposes you to different malware. Nobody can control anonymous individuals who start the torrent seeding or publish the hacked program version on the site with pirated software.
