This report identifies open HTTP proxy servers on multiple ports. While HTTP proxies have legitimate uses, they are also used for attacks or other forms of abuse.
This report concerns open HTTP proxies only, ie. ones that do not require authentication. For all accessible HTTP proxies, check out the Accessible HTTP proxy report.
How we scan
We search for open HTTP proxies (ones not requiring authentication).
We search for services that proxy HTTP CONNECT or HTTP GET requests.
Target resource we are trying to proxy to is api64.ipify.org.
We do not perform any intrusive checks on a discovered service.
As of 2023-03-30, we identify 68K open HTTP proxies.
You can track open HTTP proxies on our Dashboard here.
You can also track for specific proxy types using `http_proxy` and `http_proxy6` as a source. For example, this query lists all open proxies we find with HTTP CONNECT.
If you receive this report from us for your network or constituency you should investigate the presence of the open proxy. You may want to implement authentication or filter traffic to the service.

This report has an IPv4 and IPv6 version.
