Merged code into Ublock Origin to block Youtube Ads
  • By: Smitty
  • Made it on the frontpage of hacker news
  • You can use a Google Developer account to get a special URL that will put ads on a youtube video every time you watch it
  • Turns out the videos on Youtube are not from youtube but some Google CDN product. This CDN has caches in many popular ISP's, the demo showed the youtube video coming from a Rogers IP address, while on a Rogers Internet Connection
  • The technique youtube uses to block ad blockers uses/used JSON.stringify to validate some info, but if you overwrite JSON.stringify with the same function except it does a string replace, you can fool the youtube script to provide the direct video link rather than one with an ad
  • That method was patched, luckily there is this Javascript Proxy Function that somehow keeps our ad blockers working read the PR for more details

  • And yes, this code is running on millions of of computers including Brave Browser which just rips its filter lists from Ublock Origin
