We scan a lot of websites per day. Through our daily work we see all sizes and types of websites compromised, blacklisted, and filled with various security issues. But, we don’t often aggregate the results to provide a public report of what we are seeing.
So last month, we decided to do just that. We decided to scan the most popular websites on the internet to see how bad, or good, they are in terms of web security.
Our testing was very simple. We chose the top 1 million sites (according to Alexa), and checked the sites for those 4 issues:
- Is the site Blacklisted? Sites were checked on Google, Norton, McAfee, ESET and Sucuri Labs.
- Is the site infected with hidden SPAM?
- Is the site infected with malware like drive-by-downloads, exploit kits, and similar issues?
- Is the site running outdated software?
If the site passed those 4 tests, it would be considered safe for our testing purposes. Let’s see how the sites did.
