Bait e-mails are a pretty new strategy in malware spreading – you get the e-mail that mimics some routine notifications about shippings or bank service conditions modifications. Inside of the email, there is a corrupted MS Office file, or a link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks pretty uncomplicated, however, still requires a lot of attention.
