Sucuri is a website security company focused on the detection and remediation of web malware. In 2012, via our SiteCheck scanner, we scanned 9,953,729 unique domains. This small report is based on the data we were able to compile from that platform and our analysis of that same data.
Healthy Website View
We consider a site to be healthy when we cannot identify any unauthorized modification of its content. If any type of malware including injections, SPAM, defacements, etc. are found on a site, or if it is blacklisted by any major security company or search engine, we consider it to be compromised. Based on this view, only 74% of the sites we scan were deemed to be healthy. All the others were either blacklisted or had some malicious injection on them.
- Total unique domains scanned and analyzed: 9,953,729
- Sites in which a malicious injection was identified: 15%
- Sites in which a malicious injection was identified and it was also blacklisted: 4%
- Sites that were only blacklisted: 7%
Note that the 15% represents unique domains that were classified malicious only by our scanner via our detection mechanism. The blacklisted percentage is based on data made available by the following blacklist API’s:
