Ordinary tactics of Win32/Spy.Swisyn.GY injection are common for all other ransomware examples. Those are one-day landing web pages where victims are offered to download and install the free software, so-called bait e-mails and hacktools. Bait e-mails are a quite new tactic in malware spreading – you get the e-mail that simulates some normal notifications about shipments or bank service conditions modifications. Within the e-mail, there is a malicious 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.

Preventing it looks quite simple, however, still needs tons of attention.

Essential cybersecurity awareness is just an important thing in the modern-day world, even if your interaction with a computer remains on YouTube videos. That can keep you a lot of time and money which you would spend while trying to find a fixing guide.
