Cloudbleed Indicator Extension

Featured at Product Hunt: https://www.producthunt.com/posts/cloudbleed-indicator-for-chrome

Cloudbleed Indicator does not fix the issue, it recognises it using Google Public DNS (DNS-over-HTTPS).

If the cloud icon is bleeding, you might consider:
- changing your password,
- using 2-step verification (if available),
- leaving the site altogether.

Cloudbleed (also known as CloudLeak and CloudFlare Bug) is a security bug discovered on February 17, 2017 affecting Cloudflare's reverse proxies, which caused their edge servers to run past the end of a buffer and return memory that contained private information such as HTTP cookies, authentication tokens, HTTP POST bodies, and other sensitive data. Some of this data was cached by search engines.

Ben Lee (ID: 0000009542f4f6c8) Voted 1 ★ - Updated 02/27/2017 This is not a CloudBleed indicator, it's a CloudFlare indicator. CloudBleed only impacted very few sites and people. This is just scaremongering.
