web scan


Web scan is a browser-based network IP scanner and local IP indicator. It finds IPs leap to the client/victim by listening on an RTP data channel by WebRTC and looping rear to the port cross any live IPs, as well as finds all live IP addresses on valid subnets by watching for instant timeouts (TCP RST packets returned) from fetch() chats or hidden Image tags pointed to correct subnets/IPs. Works on mobile and computer across all main browsers and OS. The Beta version is expandable to permit the addition of many methods.

web scan takes benefits of the truth that non-responsive image tag outlets can be closed to defend browser & network-based rate-limiting by changing the src attribute to a non-outlet URI (eliminate from DOM ironically does not close the outlet), or by utilizing fetch()’s signal support of the AbortController() network.

web scan works like so

  1. Web scan first repeats by a list of general gateway IP addresses
  2. For each IP, use fetch() or image tag to get fake HTTP association to http://common.gateway.ip:1337
  3. If a TCP RST returns, the fetch() promise will be declined or the image tag on error will active before a timeout, meaning a live IP
  4. To prevent browser or interface rate limiting, non-responsive fetch() outlets are closed by AbortController() signal while image-tags have the src redirected to non-outlets URI, closing the outlet
  5. When live gateway identified, step 1-3 reran for every IP on the subnet (e.g. 192.168.0. [1-255])
  6. A WebRTC information channel is opened on the browser, opening a random port on the victim computer
  7. For any IPs that are located alive on the subnet, a WebRTC information channel connection is created to that host
  8. If the WebRTC information channel is successful, we know we just installed a connection to our local IP
