Very realistic and fake AMEX notices are circulating that are intended to infect PCs to obtain account/password information. Please be careful and keep AV updated and Windows environment fully patched on all products.
QUOTE: Right now we are seeing fake American Express account alerts. The alerts look very real, and will trick the user into clicking on a link that may lead to malware. As many of these attacks, the exact destination will heavily depend on the browser used. Most Antivirus products recognize the intermediate scripts as malicious and should warn the user if configured to inspect web content.
