How did my machine catch Deno ransomware?

Nowadays, there are three most popular ways for malefactors to have ransomware acting in your digital environment. These are email spam, Trojan injection and peer-to-peer networks.

If you access your inbox and see letters that look just like notifications from utility services companies, postal agencies like FedEx, Internet providers, and whatnot, but whose mailer is unknown to you, be wary of opening those letters. They are very likely to have a harmful item enclosed in them. So it is even riskier to download any attachments that come with letters like these.

Another thing the hackers might try is a Trojan virus model³. A Trojan is an object that infiltrates into your computer disguised as something different. Imagine, you download an installer for some program you need or an update for some service. However, what is unboxed turns out to be a harmful agent that encodes your data. Since the update wizard can have any title and any icon, you’d better be sure that you can trust the source of the things you’re downloading. The optimal way is to use the software companies’ official websites.

As for the peer-to-peer networks like torrent trackers or eMule, the threat is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is a good idea to scan the folder containing the downloaded items with the anti-malware utility as soon as the downloading is complete.
