Fake Anti-Spam Filter Leads to Keylogger

by Nino Penoliar (Anti-spam Research Engineer)

"Spam mails are very annoying, so we turn to spam filters to avoid ending up with an inbox flooded with them. Unfortunately one “anti-spam filter” we’ve encountered isn’t driving junk out, but letting them in.

We have received an email message claiming that it is from Webmail Support. It is posing as a security announcement and states that the recipient’s mail server is sending out spam because it is infected by a virus that could contaminate their contacts and other users of the network.

To correct this, it recommends the recipient to download and install an Anti-Spam filter then scan their computer so that they would not block the recipient’s email account."
