How did the Nooa ransomware get on my computer?
The Nooa ransomware spreads by placing websites to download hacked programs or games. Cybercriminals that spread this ransomware are pretty foxy, and try to keep in touch with contemporary things. New games introductions, new popular films – Nooa creators make everything to get their victims on that. One of the most preferred methods these burglars put to use is one-day websites with torrent downloading links. Nevertheless, using the contemporary news is not the only manner these criminals utilize. Ways that have already become classic, such as e-mail spamming, are also usual for STOP/Djvu ransomware distribution.
Avoiding this ransomware does not need a lot of effort. Considering the regular principles of computer hygiene will significantly decrease all risks. Remember that starting all files you get on email is not a great idea. Even worse situation is to allow macros in Microsoft Office files. However, it is much better to stop the malware intrusion at the moment when you have just opened the email message. Examining the sender’s address can say a lot about what you can anticipate, and also when you see the thing like “email@example.com”– it is likely a genuine e-mail. Meanwhile, stuff that tries to look similar to Amazon or FedEx shipping notice, however, uses the email address of “firstname.lastname@example.org”– need to make you be on the alarm. Above, you can see the example of such a message.
Outlaw sources of different digital things need some additional explanation. Going against copyright law surely throws you to the risk of being fined. Nonetheless, utilizing torrent trackers or third-party websites to download “free” programs also exposes you to different malware. No one can control anonymous people that launch the torrent seeding or publish the hacked program version on the site with pirated software.
