Wireless is a trap
I used to be an anti-wire crusader. I hated the clutter of cables, and my tendency to unconsciously chew on them if they got anywhere near my face. But running into bug after tricky wireless bug—mostly while trying to make my video calls work better—I’ve apostasized. The more I’ve learned about wifi, Bluetooth and related protocols, the more I’m convinced that they’re often worse, on net, than wir
FragAttacks: Security flaws in all Wi-Fi devices
Introduction 11 May 2021 — This website presents FragAttacks (fragmentation and aggregation attacks) which is a collection of new security vulnerabilities that affect Wi-Fi devices. An adversary that is within range of a victim's Wi-Fi network can abuse these vulnerabilities to steal user information or attack devices. Three of the discovered vulnerabilities are design flaws in the Wi-Fi standard
Understanding Wi-Fi 4/5/6/6E/7 (802.11 n/ac/ax/be)
This paper details how Wi-Fi works in the United States. While most of this paper also applies to other countries, there will be subtle Wi-Fi differences (supported channels, Tx power allowed, etc) for other countries, for which Wikipedia has the details. Faster navigation TIP: As you scroll through this paper, headers are 'sticky' and remain docked at the top of the web browser window. Clicking a
BLEを知る・触る・動かす - Qiita
以前、BLEを使ったIoT案件に携わったことがありました。そこでは、協力企業側でBLEの送受信する基盤とモジュールを用意してもらって、それをアプリに組み込む作業だったので、BLEの送受信のコアに関して、iOSとAndroidでどういう実装をしているのかまでは追うことができませんでした。 今回は、そんなBLEを知って、触って、動かすことを東京八耐でやったのでざっとまとめました。 BLE: Bluetooth Low Energy いろんなサイトにはBLEを使って何するかを基準に話されているので、規格や仕様などはWikiで確認した。 Wiki: https://ja.wikipedia.org/wiki/Bluetooth_Low_Energy 特徴・できること Wikiなどでわかったことは、次の内容でした。 「ブロードキャスト」と「コネクション」の2つの送受信ができる。 「省エネルギーである
TCP small queues and WiFi aggregation — a war story [LWN.net]
Did you know...?LWN.net is a subscriber-supported publication; we rely on subscribers to keep the entire operation going. Please help out by buying a subscription and keeping LWN on the net. This article describes our findings that connected TCP small queues (TSQ) with the behavior of advanced WiFi protocols and, in the process, solved a throughput regression. The resulting patch is already in the
Driver Backports Wiki
The Backports Project enables old kernels to run the latest drivers. "Backporting" is the process of making new software run on something old. A version of something new that's been modified to run on something old is called a "backport". The Backports Project develops tools to automate the backporting process for Linux drivers. These tools form the backports suite. History The Backports Project s
RFC 7664: Dragonfly Key Exchange
Internet Research Task Force (IRTF) D. Harkins, Ed. Request for Comments: 7664 Aruba Networks Category: Informational November 2015 ISSN: 2070-1721 Dragonfly Key Exchange Abstract This document specifies a key exchange using discrete logarithm cryptography that is authenticated using a password or passphrase. It is resistant to active attack, passive attack, and offline dictionary attack. This doc

Key Reinstallation Attacks Breaking WPA2 by forcing nonce reuse Discovered by Mathy Vanhoef of imec-DistriNet, KU Leuven, 2017 Introduction We discovered serious weaknesses in WPA2, a protocol that secures all modern protected Wi-Fi networks. An attacker within range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs). Concretely, attackers can use this novel attack
Reddit - r/openwrt - Finally got 802.11r roaming working
OpenWrt news, tools, tips and discussion. Related projects, such as DD-WRT, Tomato and OpenSAN, are also on-topic. edit Since people still find this post for advice, I'll quickly add a few notes. Configuration has been vastly simplified with a recent OpenWRT release. Basically all you need is the following: option mobility_domain 'e612' #same for all APs option ieee80211r '1' option ft_psk_generat
