What's an extender? If my router is just a normal router that connects to the modem and broadcasts wifi, I don't need to update it right?
For my phone, if I just use data when logging into financial sites instead of wifi, that would be fine?
I did update what you're replying to, in that all routers should ideally be patched because of the Fast BSS Transition handshake if the router supports 802.11r.
But using it as an extender or bridge means that you're using the router to "extend" the WiFi range, say in a large home where one router might not be able to cover everywhere.
So is this only a problem when you use wifi out and about?
In my case, I live in a rather remote location with few people around me. My nearest neighbour can't even see my router's wifi.
So does this mean an "attacker" would have to be in my driveway to intercept my wifi at home to be able to get sensitive data or do I get all of this wrong and does vicinity have nothing to do with it?
I don't use wifi outside the house so I don't connect to other networks either.
Probably not. The danger of this vulnerability is very low for most people because it is difficult to pull off, requires the attacker to be in physical range of your devices, and requires specific implementations to do the most damage (forge data). You will still want to patch any device that you may take out of the home though, like a phone, tablet, or Switch (or well, you'll want the latest security patches for all your devices, period).
Yeah that was a stupid question alright. So if i have a iPhone 4S that goes as far as IOS 9 im basically screwed?
And by saying to update the laptops do you mean updating Windows?
As of right now, yes you are screwed on an iPhone 4S. Important data SHOULD be fine as stuff like banking apps and all SHOULD be encrypted. And this attack is complicated and convoluted to pull off such that most people wouldn't ever actually fall victim to it (well, now that the exploit is known, maybe that is a different story). At some point you should move to a new device - not just because of these exploits, but the tons of other security updates that iOS brings.
Update Windows, yes. If you are on Windows 7 SP1 or the latest versions of Windows 8.1 or 10, you should be good assuming you don't have any outstanding updates available.
As I understand it: both, but for different reasons, and the client device (Phone, Windows) is the more important one.
* If you update your client device, that can connect to any router - even an outdated one - safely.
* If you update your router, any device that connects to it will do so safely, even if it is outdated.
So for any given connection, if *one* of the two devices is updated, it should be safe. Given the nature of Wifi, though, and the tendency to use it on-the-go, the client is probably the higher priority, because you can't do a security check on what AP you're connecting to.
I don't think this is true. Patches for client devices and patches for access points are fixing different attack points. I may be wrong, but I don't think vendors can patch APs to compensate for the attack on the 4-way handshake.
Thanks so much for this post, can we have it in the OP?
I skimmed everything but didn't see any direct imperatives for what I actually needed to do.
Think I'm safe. But would using a VPN add some security in the meantime? I've got one here.
Note that I did update my reply to your post.
Right now, what should you do? Update what you can. Keep an eye on security updates from the manufacturers of every WiFi-enabled device you own, including your routers. Be mindful about the devices you take around outside the home. Use HTTPS whenever possible. But I wouldn't say it's likely that someone in your area will take advantage of this and even more specifically take advantage of this against you.
A VPN would definitely help, but just make sure you have an actual good VPN, since so many, especially free ones, are complete shit in actual security and privacy.
So Netgear says there routers are only vulnarable in "Bridge mode", which apparently you need two routers to even access so I should be safe right? Or is Netgear just trying to fan the flames?
If you have a single Netgear router in the home that's connected to a modem (or an ONT or whatever), then yeah you're fine against the main vulnerability because you're probably not using it in bridge mode, but your client devices still need to be patched.
If you use a mesh solution, like Netgear's Orbi system, I would assume those need to be patched as well because of 802.11r.
The attack is against the client devices, not against the router. Patching the router is pointless (unless it's used in bridge mode). You need to patch every device that uses wifi, phone, tablet, computer, laptop, tv, smart fridge, whatever.
Worth patching the router for FT as well.
Wouldn't it only take 1 compromised device to expose the entire network's traffic? Aren't packets broadcast to the network?
In specific scenarios, I think mostly if GCMP is used, "the AP as a gateway to inject packets towards any device connected to the network" but otherwise, no. This doesn't give you complete, unhindered access to all traffic across the network. (someone correct me if I'm wrong)
I have a Dell Inspiron 15-7559 Laptop
How do I figure out what my Wi-Fi chipset is and what drivers to download?
Just update Windows.
I wonder if the 3DS or Wii will ever be patched? Wii almost certainly not.
PS3? Vita? I'm guessing the 360 has more of a chance of being patched than the other legacy systems.
I could see the 3DS being patched because Nintendo actively updates it and they're still putting out games for it. The Wii? Nope. Does it even support WPA?
Considering Sony still does stuff for PS3 (in that PSN is available and PS+ still has PS3 games)... maybe? Their last update was just under a year ago in November 2016.
I'm actually on iOS 9 something because I heard enough bad things about iOS 10 (annoying unlock feature specifically)
Lucky me though, the stone walls in our house block pretty much all WiFi signals anyway
Well if you don't use WiFi anywhere else with your iPhone, then I guess you're good
