In a previous post, we pointed out how just browsing the web these days can possibly infect your PC with malware. To show how dangerous surfing can become, Symantec recently released their list of the “Dirtiest Websites of Summer” – the top 100 infected sites on the Internet based on number of threats detected by their software as of August 2009. The list identifies websites that could compromise security with risks including phishing, malicious downloads, browser exploits, and links to unsafe external sites.
Some interesting findings from the study:
- The average number of threats per site on the Dirtiest Websites list is roughly 18,000, compared to 23 threats per site for most sites
- 40 of the Top 100 Dirtiest Sites have more than 20,000 threats per site
- 48% of the Top 100 Dirtiest Web sites feature adult content
- 3/4 of the Top 100 Dirtiest Web sites have distributed malware for more than 6 months
- Viruses are the most common threat represented on the Dirtiest Websites list, followed by security risks and browser exploits
