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

Preventing this ransomware does not require a lot of initiative. Considering the ordinary principles of computer hygiene will substantially minimize all risks. Remember that starting all files you get on e-mail is not a good option. Even worse scenario is to allow macros in Microsoft Office documents. But it is far better to prevent the malware intrusion at the moment when you have just opened the email message. Inspecting the sender’s address can point out a lot about what you can anticipate, and when you see the thing like “support@amazon.com”– it is likely a legitimate email. On the other hand, stuff that tries to look like Amazon or FedEx shipment notice, but uses the e-mail address of “amazonspurrot1363@gmail.com”– need to make you get on the alarm. Above, you can see the example of such a message.

Illegal sources of various digital things need some extra explanation. Going against copyright regulation surely throws you to the danger of being fined. However, utilizing torrent trackers or third-party websites to download “free” programs likewise exposes you to a wide range of malware. No one can control undisclosed individuals who start the torrent seeding or publish the hacked program version on the site with pirated program.
