We’ve previously blogged about Olympic ticket scams, phishing, malware designed to propagate through social networking, and other Olympic security concerns.
We also know that hackers take advantage of people searching for breaking news and trending topics about the Olympics through various SEO poisoning techniques. When Georgian luger Nodar Kumaritashvilii died in a tragic training accident just before the Vancouver Olympics in 2010, multiple malware pages quickly appeared in the top search results.

Looking more closely at the data, we found that a handful of Twitter feeds from certain athletes and teams were posting shortened URLs which redirected to Objectionable or Security categories, including Malicious Web Sites and Malicious Embedded Link:
We took a sample set of 3600 of these, unshortened them, and analyzed the category breakdown:
