Forscher entdecken eine massive Wi-Fi-Schwachstelle, die mehrere Zugangspunkte betrifft – AirSnitch ermöglicht es Angreifern im selben Netzwerk, Daten abzufangen und Machine-in-the-Middle-Angriffe zu starten

You ever feel bad for those who are not technically inclined? Oh my ISP may handle that for me at some point … this is much worse. This is like coworker espionage and we are all fair game.
Does this affect routers with OpenWRT?
> attackers on the same network intercept data and launch machine-in-the-middle attacks
Yes, that’s how being on the same network works and is why we have HTTPS.
Shitty title, shitty article.
Reading the actual paper (https://www.ndss-symposium.org/wp-content/uploads/2026-f1282-paper.pdf)
> In this paper, we undertake a structured security analysis of
Wi-Fi client isolation and uncover new classes of attacks that
bypass this protection.
Yeah, that’s more like it, it’s just attacking mitigation for attacks that have existed since the dawn of the internet, which this article is presenting as some breakthrough vulnerability.
The practical part here is that ‘same network’ still describes a lot of real-world risk: hotels, airports, conferences, schools, coworking spaces, and any flat network at home or in small offices. If the advisory holds up, admins should be thinking about firmware updates, client isolation/guest networks, and moving sensitive workflows off shared Wi‑Fi where possible rather than treating this like an abstract lab bug. The bigger lesson is that Wi‑Fi gear often lives unpatched for years, so router/access-point update hygiene matters way more than most people assume.
And this is why we’re on WPA3 now. This isn’t anything new about WPA2 networks.
It was only a matter of time Wi-Fi is very old Tech.
