Making the issue even more severe was the fact that search engines were caching that leaked information. The user who posted the Github list still recommended users of all those sites change their passwords as a precaution. CloudFlare, Google and other search engine providers have been scouring the web looking for sites that may have leaked information via the CloudBleed bug. They found 161 unique domains where leaked memory had been cached by the search engines, and that data has now been purged. "We also undertook other search expeditions looking for potentially leaked information on sites like Pastebin and did not find anything," CloudFlare added.
