Where did I get the Backdoor:Win32/Farfli.BI!MTB?

Usual tactics of Backdoor:Win32/Farfli.BI!MTB spreading are basic for all other ransomware examples. Those are one-day landing sites where users are offered to download the free software, so-called bait e-mails and hacktools. Bait e-mails are a quite new method in malware spreading – you receive the email that mimics some normal notifications about shippings or bank service conditions modifications. Within the email, there is a malicious MS Office file, or a link which opens the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks fairly simple, however, still needs a lot of attention.

Common cybersecurity awareness is just an essential item in the modern world, even if your interaction with a computer stays on YouTube videos. That can save you a lot of time and money which you would spend while trying to find a fixing guide.
