How did the Kruu ransomware get on my computer?
The Kruu ransomware spreads by placing links to download hacked programs or games. Cybercriminals that spread this ransomware are very tricky, and try to keep in touch with current trends. New games releases, new popular films – Kruu developers make everything to get their victims on that. Some of the most common strategies these burglars use is one-day sites with torrent downloading links. Nonetheless, pursuing the contemporary things is not the single tactic these crooks utilize. Methods that have already turned into standard, such as e-mail spamming, are also normal for STOP/Djvu ransomware distribution.
Avoiding this ransomware does not require a lot of initiative. Considering the regular principles of computer hygiene will substantially minimize all dangers. Keep in mind that starting all documents you get on email is not a good idea. Even worse situation is to enable macros in Microsoft Office documents. But it is better to stop the malware attack at the moment when you have only opened the email message. Inspecting the sender’s address can point out a lot about what you can anticipate, and when you see things like “firstname.lastname@example.org”– it is likely a genuine e-mail. On the other hand, stuff that tries to appear like Amazon or FedEx delivery notice, but uses the email address of “email@example.com”– should make you get on the alarm. Above, you can see the example of such a message.
Illegal sources of different digital things require some extra description. Violating copyright law already throws you to the chance of being fined. Nonetheless, using torrent trackers or third-party websites to download “free” programs also exposes you to various malware. Nobody can oversee undisclosed people who start the torrent seeding or publish the hacked program version on the site with pirated program.
