But a little known community of software developers is trying to change that, by creating a searchable, public index of websites with known security issues. Think of Project Un1c0rn as a Google for site security. Launched on May 15th, the site's creators say that so far it has indexed 59,000 websites and counting. The goal, according to its founders, is to document open leaks caused by the Heartbleed bug, as well as "access to users' databases" in Mongo DB and MySQL. According to the developers, those three types of vulnerabilities are most widespread because they rely on commonly used tools. For example, Mongo databases are used by popular sites like LinkedIn, Expedia, and SourceForge, while MySQL powers applications such as WordPress, Drupal or Joomla, and are even used by Twitter, Google and Facebook.
