Ordinary tactics of Trojan:Win32/Gamaredon.psyU!MTB distribution are standard for all other ransomware variants. Those are one-day landing web pages where users are offered to download the free software, so-called bait emails and hacktools. Bait emails are a relatively modern tactic in malware spreading – you receive the e-mail that imitates some routine notifications about deliveries or bank service conditions modifications. Inside of the e-mail, there is a corrupted 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 pretty easy, however, still requires tons of focus. Malware can hide in different places, and it is far better to prevent it even before it goes into your computer than to rely on an anti-malware program. Standard cybersecurity knowledge is just an important item in the modern-day world, even if your interaction with a PC remains on YouTube videos. That may save you a lot of money and time which you would certainly spend while searching for a solution.
