Usual tactics of Trojan-Ransom.Win32.GandCrypt.gvq spreading are typical for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait emails are a relatively modern tactic in malware spreading – you receive the e-mail that imitates some standard notifications about deliveries or bank service conditions shifts. Inside of the email, there is a corrupted MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks quite easy, but still requires tons of focus.

Common cybersecurity knowledge is just an essential item in the modern world, even if your relationship with a computer remains on YouTube videos. That can keep you a lot of time and money which you would certainly spend while searching for a fix guide.
