Today we saw a Viagra campaign hitting our spamtraps. It's not unusual to see Viagra campaigns, the notable aspect is the different tactics the spammers are implementing to evade spam filters 2.
In today's case we saw spammers using newsletter templates in their emails. Online newsletters are the most common mechanism used by most organisations to keep their customers up to date. Spammers are exploiting this technique to evade spam filters and fool users by trying to appear legitimate.
To make this look more authentic you can also see them including useful links at the bottom of the mail. if you click on any of the URL's believing this to be a legitimate newsletter, you will land on this Canadian pharmacy page.
Sophos successfully blocks this campaign. Next time you see unsolicited emails with legitimate newsletter templates think twice before you click on the links.
