There has been a recent increase in “greeting-card spam” that tries to compromise users by getting them to visit malicious websites. The subject line most often states, “You've received a postcard from a family member!” Within the message body, users are given options on how to retrieve their “postcard”. Links in the message direct users to malicious websites where their browsers may be attacked, or they may be prompted to download and execute malicious software.
