We often take for granted just how ubiquitous Wi-Fi has become over the past two decades, explains Northeastern University electrical and computer engineering professor Francesco Restuccia, who is also a member of the Institute for the Wireless Internet of Things.

    Does anyone have more information than what is included in the article?

    This sounds like a basic DOS attack initiated by poisoning the information the router uses to split resources/bandwidth/communication time between multiple users. The important piece will be if it requires an attacker to be authenticated with the AP to pull off.

    As far as I’m aware, modern WPA2 encryption is still secure against brute force and replay attacks unless you’re using WPS Pins for authentication (and I haven’t seen a device with that in ages). So this appears to be just another case of “keep untrusted devices off your WLAN”.

    Edit: I am SUPER out of date with my wifi security knowledge.

      I was cracking wpa2 aes networks over a decade ago, they are not secure to brute force and replay attacks lol you’d need PMF forced on to prevent replay attacks but this breaks compatibility with half the shit on the market

      Security is only as strong as the password, where modern hardware can achieve hashrates that quickly break all but complex phrases

    This is sorta off topic but I’d love to see comparisons of MU-MIMO 4x4 and different manufacturers APs that support OFDMA and see some real world numbers. I guess use case does matter high/low throughput, interference, how many clients, etc. still would love to see like to like speed comparison as they both accomplish the same thing just wildly different.
