WeвЂ™ve always wondered when weвЂ™d see the first ESP8266 attacks in the wild, and that day has finally come.

But those crusty old NodeMCU builds that weвЂ™ve got running everything in our house? Time for a full recompile. ItвЂ™s even percolated downstream into the Arduino-for-ESP, where itвЂ™s just been worked into the latest release a few hours ago. He also wrote us that if youвЂ™re stuck with a bunch of ESP8266s in an EAP environment, you should at least encrypt and sign your data to prevent eavesdropping and/or replay attacks.ДЄgain, because informed Espressif first, most of the bugs are already fixed. points out the irony that if youвЂ™re using WPA2, youвЂ™re actually safer than if youвЂ™re unpatched and using the nominally more secure EAP.

We have no idea how many ESP8266 devices are out there in EAP networks, but weвЂ™d really like to see Espressif patch up this hole anyway.

So as of now, if youвЂ™re running an ESP8266 on EAP, youвЂ™re vulnerable. The ESP32 codebase has already been patched against them, but the older ESP8266 SDK has not yet. These EAP hacks are more troubling, and not just because session hijacking is more dangerous than a crash-DOS scenario. One hack makes the ESP32 or ESP8266 on the EAP-enabled network crash, but the other hack allows for a complete hijacking of the encrypted session. The second and third vulnerabilities exploit bugs in the way the ESP libraries handle the extensible authentication protocol (EAP) which is mostly used in enterprise and higher-security environments. Crash-ception! This takes advantage of the ESPвЂ™s packet injection mode, which weвЂ™ve covered before. WhatвЂ™s most fun about the beacon frame crasher is that it can be implemented on an ESP8266 as well. If you can send an ESP8266 a bogus beacon frame or probe response, you can crash it. Because the ESP doesnвЂ™t do bounds-checking on this value, a malicious fake access point can send a large number here, probably overflowing a buffer, but definitely crashing the ESP. While connecting to an access point, the access point sends the ESP8266 an вЂњAKM suite countвЂќ field that contains the number of authentication methods that are available for the connection. The first flaw is the simplest, and only effects ESP8266s.

He notified Espressif first (thanks!) and theyвЂ™ve patched around most of the vulnerabilities already, but if youвЂ™re running software on any of these chips thatвЂ™s in a critical environment, youвЂ™d better push up new firmware pretty quick. Just came out with three (3!) different WiFi attacks on the popular ESP32/8266 family of chips.
