Once an item is exposed on the internet, it’s there forever. Although content delivery network Cloudflare has fixed the problem in its code that resulted in leaking customer data across the web, the incident is far from over for the millions of websites that rely on the company for security and content optimization services.
What makes this leak so odd and frustrating is that website administrators don’t actually know if their information was leaked or where it wound up. Although Cloudflare knows which customers were affected based on data found in search-engine-cached files, it doesn’t know what information was actually exposed or to whom.
