Fake Amazon Kindle receipt leads to persistent malware

Amazon customers buying e-books for his or her Kindle or other mobile devices must be careful with emails that seemingly containing receipts for his or her purchases, warns Webroot, as malware peddlers have another time started a spam campaign impersonating the e-commerce giant:

I doubt that the attackers have managed to compromise an Amazon database and exfiltrate user information akin to name and billing address (in the event that they had, we might have heard about it by now), so the synthetic and random information inside the “receipt” could trick some users into following the offered links to their accounts which will discover how the error happened.

Those who do will land on compromised pages hosting the Blackhole exploit kit, and upon successful client-side exploitation, should be infected with a variant of the Kryptik Trojan.

The Trojan in question infects local and network Windows platform computers, hides running processes, prevents AV software to be updated and work because it should, and is normally an extremely persistent piece of malware.

Once again, users are advised never to follow links contained in unsolicited emails and to match and access their online accounts via the legitimate login page.
