Akamai/Internet DNS Problems
Starting at around 8:30 am EDT (12:30 UTC), a number of sources started to report a widespread Akamai DNS issue. Large web sites, which use Akamai for its DNS service, no longer resolved in DNS, and became inaccessible to their users. The affected sites were Yahoo, Google, Microsoft, FedEx, Xerox, Apple and likely many others. The situation improved around 10:30 EDT, mainly because some of the affected domains temporarily switched from using Akamai DNS servers to their own DNS servers.
The problems seem to be attributable to a DDoS attack on Akamai's DNS servers, though we do not presently have the information to make a definitive assessment. According to the Akamai spokesperson, the problem was not limited to Akamai. He attributed the outage to an attack on the Internet infrastructure on a larger scale. We do not currently know of any sites that were affected by the attack without using Akamai's services.

Continued Exploitation of IE URL Spoofing
Today's post to the Full Disclosure mailing list warned readers about a phishing scam that directed its victims to a well-designed website that posed as the U.S. Bank site. The site uses an Internet Explorer flaw to place text outside the rendered page window and over the URL location bar, leading victims to believe that they are actually visiting a real banking site. The exploit cleverly calculates where to position the text, and works surprisingly well for most installations of Internet Explorer. Other browsers are not affected by the problem, as far as we know.
The U.S. Bank-spoofing site uses the same exploit as the PayPal-spoofing site reported recently on a Broadband Reports forum. The same exploit was used by another PayPal-spoofing site that we saw several weeks ago. These attack vectors are based on the Bugtraq post that dates to approximately a year ago. We are alarmed at the increased number of exploit sightings in the wild, and are not aware of an Internet Explorer that corrects this issue.
