Intelligent Reflecting Surfaces prevented 95% of wifi attacks is not only not the original title, it is also misleading. The article is about preventing the use of wi-fi sensing to track individuals inside their homes. The correct title is Preventing eavesdropping via the Internet of Things

Most consumers are not familiar with Wi-Fi sensing, which can be used to remotely monitor keyboard typing, human heartbeats and other business or home motion by humans and pets. The 2024 launch of IEEE 802.11bf Wi-Fi 7 Sensing will make "X-Ray Vision" accessible to hundreds of millions of consumers globally, unless nation-state regulators intervene. E.g. the introduction of radar sensing on 2.4Ghz/5Ghz/60Ghz could be delayed until local construction/building codes are upgraded to define standards for wireless shielding.

  Assume a building with zero wifi in it.... Can't an enemy simply place wifi routers of its own around the building and monitor what they want freely from their own radios?

    Yes, of course. The threat is from wardriving/neighboring wireless devices outside building walls, whose radio waves (2.4Ghz) penetrate the walls of your business or home. This can be done today with $20 ESP32 devices and custom firmware, the difference with Wi-Fi 7 is that it will be built into consumer routers and sold as a feature for monitoring humans (babies, elderly, security, Minority Report-style 3D gesture recognition combined with VR/AR 3D room models from iPhone/iPad Pro lidar). Through-wall Wi-Fi sensing potentially affects anyone who types a password into a computer without 2FA, or uses a physical safe with combination lock or electronic button. Many physical door locks are not secure, so an intruder can enter a building once without detection, to perform a detailed 3D scan of the interior for correlation with external Wi-Fi sensing observations. e.g. here is a photorealistic 3D model of an apartment in San Francisco, generated by an iPhone Pro lidar interior scan by an AirBnb customer, https://poly.cam/capture/C0EBFFE1-FF80-49FC-B308-A8A3E67930FF https://poly.cam/capture/C0EBFFE1-FF80-49FC-B308-A8A3E67930F.... If Wi-Fi 7 Sensing becomes widely available, the interior 3D lidar+photo scan could be combined with an exterior 3D radar scan of the interior. Do AirBnB hosts know their properties can be 3D-scanned?

      WOW. Ive not seen one of those iphone lidar caps before... Cant wait until the "obsolete" iphones are just "brain-cards" you slot into a drone body of whatever format you want send it off, and when it returns you just pull the iphone from the slot... or better yet - the drone delivers it as a payload to a spot... What if you have a "drone vending/rental machine" , you select what drone body you want to rent thats compatible with your cpu-drone-phone... rent the thing, stick in the phone to access and control it... with the app on the phone all configured to your settings (wherre it will upload, who controls it, blah blah) When your rental is over - the drone 'phones-home' and sheds its exoskeleton and you take your plane-brain with you!

  They all laughed because of my lead paint. Well who is laughing now?
