Where did I get the Win32/GenKryptik.GASB?

Standard tactics of Win32/GenKryptik.GASB injection are standard for all other ransomware variants. Those are one-day landing websites where victims are offered to download the free program, so-called bait e-mails and hacktools. Bait e-mails are a pretty new tactic in malware distribution – you receive the email that mimics some normal notifications about deliveries or bank service conditions updates. Within the email, there is a malicious MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

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

Avoiding it looks quite uncomplicated, but still requires tons of attention. Malware can hide in different spots, and it is far better to stop it even before it gets into your PC than to depend on an anti-malware program. Simple cybersecurity knowledge is just an important thing in the modern world, even if your interaction with a computer stays on YouTube videos. That can save you a great deal of money and time which you would spend while seeking a solution.
