Those are one-day landing web pages where victims are offered to download the free software, so-called bait e-mails and hacktools. Bait emails are a quite modern strategy in malware distribution – you get the email that imitates some routine notifications about shippings or bank service conditions modifications. Inside of the e-mail, 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.
