Cybercriminals continue to populate their botnets, with new infected hosts, through the persistent and systematic spamvertising of tens of thousands of fake emails which impersonate popular and well known brands – all in an attempt to socially engineer prospective victims into interacting with the scam.

We’ve recently intercepted a currently circulating malicious spam campaign, impersonating Evernote, serving client-side exploits to prospective victims who click on the links found in the fake emails.
