Phishing with Malware

I've been pretty busy lately with work and the malware challenge (only 11 days left!) but I figured I'd post something which came across my inbox today. Wachovia has been getting alot of phishing attempts against it which lead to a page trying to get you to install a security update, which is actually malware. I guess the bad guys decided that Wachovia had enough and decided to turn their sites on Key Bank.

I received the following email supposedly from Key Bank asking that I update my system now.

Clicking on the link took me to the following page, which is NOT located on Key Bank's website.

If you wait long enough it will refresh itself to the executable, but by clicking on the link the page will attempt to download and run (with user acceptance) the malware and will open up another browser window to the actual Key Bank login page. This page IS on Key Bank's website, but note that Key Bank is NOT compromised.

What has happened is when the user installs the "update" the initial malware loaded downloads another one which installs itself as a service on the system. This new service then watches for any credentials sent. What happens when it gets one?

This isn't a new method for doing things - its been around for a while. However, this is the first time I've seen this specific attack (from this group) directed at Key Bank. Trend Micro has a posting about the same attack against a German bank.
