Vera vulnerable to Wi-Fi Krack exploit?
« on: October 17, 2017, 11:38:25 pm »
I must assume the MCV folks are aware of the Wi-Fi issue. Any news on a patch?

The issue is not so much with Vera as it is with the WPA/WPA2 encryption protocol. Which is part of the underlaying OpenWRT OS that MIOS runs on.

TBH, this is really the least of your worries with Vera, because of the very sloppy approach to secure handling of data and the inherent vulnerabilities of UPnP.

The fix is for clients that attach to a WIFI hotspot ...
If you connect your Vera via WIFI you are vulnerable ... Use a wired connection!
There are LOTS of wifi devices in my house ... that I doubt I can get software updates for.
The software in Vera is VERY OLD ...
It's based on the OpenWRT Barrier Breaker release from the end of 2014.

The latest OpenWrt (15.05.1) is also vulnerable to KRACK. You would need to move to the fork of OpenWrt, LEDE, release 17.01.4, to have the version of hostapd/wpad/wpa-supplicant that is patched against KRACK.

I don?t see Vera doing this TBH.

I have WiFi switched off on my Vera's as I have an existing WiFi setup already. Running DD-WRT so I'm keeping an eye out for a patched version of that.  It has a whitelisted MAC table, which although not foolproof (MAC spoof anyone) will make it a bit more time-consuming. Hopefully giving my IDS enough time to catch on and have it tell the gateway to drop the LAN port for the WiFi network and send me an alert.

I wouldn't stress out too much. How valuable is the information that is being sent to and from Vera via wifi? Valuable enough for someone to take the trouble of sitting within range of your wifi connection to monitor and intercept it? I hope not. VERA and products like it are toys and should never be used for anything beyond the trivial.

I don't send any information that is worth a plug nickel to anyone via wifi .  I have a few devices that can initiate scenes, but that's about it. S.P.E.C.T.R.E. or T.H.R.U.S.H. would be profoundly disappointed in the extortion opportunities provided by gaining control of my kitchen light. In other words,  the best security system is not being a valuable target in the first place.

I'm not really worried. As I said Vera's WiFi is off. As for my WiFi network, I'm hoping for a patch for DD-WRT soon so I can plug the hole but I'm not sweating it. If someone sits on the street in front of my house in a car, my K9 security system will detect that and alert. Since I have a camera on them, I'm pretty sure I will notice their behaviour. I also have a camera aimed down my drive so I would be able to see Mr. or Mrs.B. Hat and catch them in the act. :-) Easy enough to SSH into my home server and drop the WiFi LAN port to stop their game.

Probably more than enough to tell whether you're in or out...

Or they could just knock on the door....  (and yes, that has happened to me.)

All of the local bad guys that I am aware of do not have the smarts to perform computer hacking.

Like I said, I have a K9 security system which is quite capable of handling physical break-ins.  8)

@Richard: Now there's an idea... For now they just handle the physical side. I wonder if Alexa understands dog so they could bark at her to get stuff done. :)

It shouldn't be. I keep my security system and automation devices separated. Same with my cameras. Vera can close my garage door but the trigger runs through a reed switch so it it physically isolated if the door is closed. My cameras are hard-wired on an isolated subnet and I use a physical contact closure to activate panic lighting via the alarm. Vera and products like it are not security or life safety devices and should not be relied upon for critical functions.

Just my two cents. Which I intend to keep safe.
