How did the Hruu ransomware get on my computer?

The Hruu ransomware spreads by placing websites to get hacked programs or games. Cybercriminals who spread this ransomware are very clever, and aim to correspond with contemporary things. New games introductions, new popular movies – Hruu creators make whatever to get their money on that. One of the most popular techniques these crooks use is one-day websites with torrent downloading links. However, following the modern-day news is not the single way these crooks utilize. Options that have already become standard, such as e-mail spamming, are likewise ordinary for STOP/Djvu ransomware spreading.

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

Preventing this ransomware does not need a lot of effort. Considering the standard rules of computer hygiene will noticeably reduce all hazards. Remember that opening all documents you get on email is not a great idea. Even worse case is to enable macros in Microsoft Office documents. However, it is much better to prevent the malware attack at the moment when you have only opened the email message. Inspecting the sender’s address can say a lot about what you can expect, and 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 notice, however, uses the email address of “amazonspurrot1363@gmail.com”– need to make you be on the alarm. Above, you can see the example of such a message.

Outlaw sources of different digital things require some additional description. Violating copyright law already throws you to the chance of being fined. However, using torrent trackers or third-party websites to download “free” programs also exposes you to a wide range of malware. No one can control undisclosed people who launch the torrent seeding or publish the hacked program version on the website with pirated program.
