Where did I get the MSIL/Spy.Keylogger.DUS?

Standard ways of MSIL/Spy.Keylogger.DUS distribution are common for all other ransomware variants. Those are one-day landing web pages where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait emails are a pretty modern tactic in malware spreading – you get the e-mail that mimics some regular notifications about shipments or bank service conditions changes. Within the e-mail, there is a corrupted MS Office file, or a web link which leads to the exploit landing site.

Malicious email spam

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

Preventing it looks pretty simple, however, still needs a lot of recognition. Malware can hide in various places, and it is better to stop it even before it invades your PC than to depend on an anti-malware program. Essential cybersecurity awareness is just an important thing in the modern world, even if your relationship with a computer stays on YouTube videos. That may keep you a lot of time and money which you would spend while seeking a fix guide.
