The SANS Institute is warning of an increased threat to users from Trojan remote access programs installed by web links to emailed greetings messages, such as postcards.

The SANS Institute said it was monitoring increased use of such scams by hackers looking to install remotely controlled malware on users’ machines.
Users think they are accessing a friendly greeting when clicking on the link in the message, but instead they are directed to a malicious website that downloads the Trojan onto their machine.
Such a Trojan could install key-logging software onto their PC, meaning criminals could remotely capture usernames and passwords for online banking accounts, for instance.
