Where did I get the Win32/Autoit.OJM?

Common ways of Win32/Autoit.OJM injection are basic for all other ransomware variants. Those are one-day landing websites where victims are offered to download the free software, so-called bait emails and hacktools. Bait e-mails are a pretty new strategy in malware spreading – you receive the e-mail that mimics some normal notifications about deliveries or bank service conditions changes. Inside of the email, there is a corrupted MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Avoiding it looks pretty simple, but still requires tons of awareness. Malware can hide in various spots, and it is better to prevent it even before it gets into your computer than to trust in an anti-malware program. Basic cybersecurity knowledge is just an essential thing in the modern world, even if your relationship with a computer remains on YouTube videos. That can save you a great deal of time and money which you would spend while trying to find a solution.
