Criminals are targeting Google AdWords customers with phony emails requesting the victim download a 128-bit SSL certificate. A client received this version (there are quite a few variations):
From: Google Adwords account [mailto:firstname.lastname@example.org]
Sent: Monday, September 29, 2008 8:52 PM
To: <potential victim>
Subject: Google Adwords Alert
Attention GOOGLE ADWORDS Customers!
For certain services, such as our advertising programs, we request 128-bit SSL security information which we maintain in encrypted form on secure servers.
We take appropriate security measures to protect against unauthorized access to our unauthorized alteration, disclosure or destruction of data.

Unsuspecting victims who click on the “Read more” link are taken to a malicious website where their machine is infected with a keylogger rootkit. The URL of the site varies, but is similar to this one:
Of course, the actual domain the person arrives at isn’t google.com, but, in this case, mekefri.com.
