Those are one-day landing websites where users are offered to download and install the free app, so-called bait emails and hacktools. Bait emails are a quite new method in malware distribution – you receive the e-mail that mimics some routine notifications about deliveries or bank service conditions updates. Within the email, there is a corrupted MS Office file, or a link which opens the exploit landing page.

Malicious email spam

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

That can keep you a great deal of money and time which you would certainly spend while looking for a solution.
