    I would imagine a large amount of unencrypted access points are "guest APs", where you log in with a username and password after connecting, or perhaps no authentication at all (by design).

      I was wondering that too. Considering that all the Starbucks or BTopenzone and the like have no protection, then it's no surprise.

      What this guy should be saying is that the WiFi standards group are still completely crap if they cannot implement a standard that allows anyone to connect without needing a password, and then for the two devices to negotiate a secure connection between them.

      The current standards either have no protection, or the requirement to enter a 140 bit key on an on-screen keyboard the size of a postage stamp, and no way to know what that key is unless people stick post-it notes up on every lamp-post.

      As for honeypots; aren't they one of the reasons for VPN?

        PKI

        We theoretically could solve the issue with PKI, but even "type down this password on your device" is too much of a hassle for non-techies. Interestingly, the one place where I've seen PKI used for "public" WiFi access is at DEF CON, but then that's because you know most people going there are going to be tech savvy to boot. And the one thing that was made to do this easily (WPS) has the stupid PIN method which can be cracked easily, thus the method being disabled by anyone tech savvy these days...

      It is still bad practice. You should never connect to an access spot without a WPA2 passphrase. A VPN can go some way to mitigating that, but even so...

      A business offering free wifi should set the password to their business name or have the password prominently displayed for their customers.

      Our guest WLAN at work is WPA2 enctrypted and we have QR-Codes for smartphone and tablet users to set up the connection automatically and the password is available upon request for PC users.

        So all I need are some stickers and I can mess up your guest WLAN, or worse, send your tablet/smartphone users to my malware-ridden network or site instead?

      Why would anyone turn on encryption and require credentials on a consumer internet only connection anyway? It just slows down your traffic. I leave my WiFi connections open for anyone to use and turn off all logging - and i'm in a quite busy area - have done for years without any issues at all. I have a VPN account for any traffic I really care about, but in general checking that EV certificates are valid does me.

      It also quite incidentally makes any accusations of say sharing copyrighted content quite deniable too.

      That and decade old domestic broadband routers that have sat on the phone stand since they were delivered, only being replaced if the owner moved house and was sent a new router for their new line, or if it went on the fritz. My parent's Orange Livebox went on 5 years before a thunderstorm spiked the phone line and the router with it, and it's replacement has been going for the best part of a decade.

      No reason they will replace it unless it dies or they get sent a shiny new box for a fibre connection, which won't happen because fibre isn't coming to their rural backwater. Ever.

      On the plus side their old farmhouse has "proper" walls built of stone and brick, not plasterboard and wood, so the wifi barely makes it downstairs, much less outside the house or the mile to their nearest neighbour (who has no line of sight in any case). The odds of anyone sniffing that access point are somewhere approaching nil.

        The website owner decides what CA to use. You could manually check every certificate you receive for an https site to see if you think it is valid, but you probably won't do a better job than your browser already has.

        Yep, just like a VPN, HTTPS is vulnerable at initial connection establishment.

        To avoid the connection establishment (in public hotspot) vulnerability you could use a persistent session, but these are frowned upon by the security experts...

    Use WPA2? Fine, I won't argue with that - but where, pray tell, should the VPN be directed to connect? Definitely not all home routers currently in use come with that built-in (given the owner has any idea he does have it at all)? Who says there even is anything permanently 'on' on the home LAN - there might be no router at all? Heck, there might not be any home LAN at all for some people...!

      re: Had to downgrade security as the TV supports WEP!

      If you had a spare wireless router (or even a Pi or netbook with a wifi dongle that can work in access point mode), you could have set it up to firewall the WEP-only devices from the rest of your network. Give them a free route out to the internet, but don't let them access anything else.

      Once you learn how to configure this sort of thing, it has a variety of uses. Over the last few years I've had a DMZ (home ftp server receiving requests directly from the net, but firewalled from all my other machines), a separate "guest" wireless network (like your WEP-only scenario) and more recently I set up fail-over networking (tethering to my phone) for when the main broadband goes down. I guess I should also use VPN for when I'm connecting to public wifi with my phone, but that doesn't happen regularly enough for me to worry about it.

          Using the MAC provides absolutely NO!! security. Using aircrack-ng and other software I can clone the MAC and crack WEP from over 500 ft. away. The only security for a home network is a good pass phrase.

          Re: re: Had to downgrade security as the TV supports WEP!

          Indeed, I just finished doing the same scan in Las Vegas and there are a huge number of networks with exactly that setup. Their SSID is easily identifiable as it shares the SSID followed by _guest or alike. Of course, a lot of them are open and while the intended user (the household) may not expect to do anything to sensitive others might. Also, seemingly innocuous downloading and browsing can allow for insertion of nasty JavaScript, social engineering pages or other manipulation. It sounds like you aren't going to be falling for it, but I doubt everyone in our study behaves the same way ;-)

      That's what I thought too. I'm not entirely sure that there is much to be learned for the information provided.

      As for MAC blocking that is not secure, as you say, however it does mean that only "hackers" will get in. Nevertheless, if one only allows one connection at a time then the worst that someone could do is read the stream which is generally of no consequence.

        Re: only allows specified MACs to connect

        Blocked SSIDs still leak and MACs are easily tweaked.

        At least some of the kit I've used happily shows the SSID of "cloaked" APs.

        WPA2 is only secure when used in conjunction with a decent password, as otherwise a snoop session can deduce the password over a few hours without issuing any packets (or it can bother the AP for more data, faster)

    Labor Intensive

    It seems like working out a deal with cab companies in the target cities would be a lot easier and deliver a considerably more robust data set that evolves over time. You could also develop targeted awareness campaigns for dense trouble spots. You could probably even talk banks into paying for the exercise.

    There's an apartment building in Alexandria, VA where an interested tenant put a flyer on everyone's door with basic info about open networks and put his email address and phone number there with an offer to help secure their networks for free. A month later there are zero open networks in the building. People didn't even get too mad about the flyers he wasn't supposed to be posting.

    What I'm getting at, is that traditional awareness techniques have obviously penetrated as far as they are going to go. People that aren't aware aren't going to be aware unless they are informed in a new way and you need to find those people, and track the effectiveness of the new message delivery vehicle(s). A tech guy doing a tech thing being covered on a tech site has a rather small audience that isn't aware of open network risks.

    VPN's are safer...but are they safe?

    I've been a long-timer user of VPN's on my laptops, primarily to allow me to safely use public networks. So, when I finally got an Android phone, this was one of the first things that I set up on it.

    However, despite constantly seeing VPN's quoted as the cure-all for public networks, I have been unable to adequately protect my (unrooted) phone, as I can't find a VPN/app which blocks traffic before it's connected. I've spoken to a number of leading VPN providers and they have all, eventually, admitted this as a problem - the "best" response I got was the company who said they were working on a solution.

    Does anyone who, unlike me, knows something about Android, know of a solution to this?

    Thanks,

    David.

      Re: VPN's are safer...but are they safe?

      There are always going to be tradeoffs with any type of security. It doesn't matter if it's data, gold bullion or hostages. Usability and security are two sides of the same coin. Once something is absolutely secure it becomes a Schrodinger's Cat sort of thing. Is the thing you're protecting really still in there? The only way to know for sure is to look, but then your thing is no longer secure.

      But you've got the traditional valuation problem. If the thing you're tying to protect is so valuable that making it inaccessible, thus truly secure, is the thing really that valuable? Only you can decide that. Museums have been tossing that problem around for a good century or so now. They go back and forth on the issue every few years. Most organizations and individuals with the means eventually say fuck it, and just insure the hell out of whatever it is. You still practice the security fundamentals, but the value of something is reduced by the value of time and resources you put into protecting it,

      But to answer your question, there's no pre-connect blocking VPN for Android. My wife uses Android and she hasn't been able to find an OTS solution either. She just doesn't do anything involving potentially dangerous personal info with those devices.

    2. Aslan

      Re: VPN's are safer...but are they safe?

      The solution is just get root already you really should have posted your phone model here so you could be helped with that, and then install Cyanogenmod. If you're a nervous Nelly about getting root access through some security hole your phone manufacturer has allowed to persist for the last year (on Windows these are the updates that get a critical label), the buy a Nexus 5 phone which allows you to easily and officially take root privileges. https://www.google.com/nexus/ or if you're really serious there's always https://www.blackphone.ch/

      Basically any VPN that blocks traffic before there is a VPN connection is going to be hacking your phone as bad as anything that give you root privileges unless something changes in a future version of Android.

    Surprisingly

    I live in one of the less salubrious bits of east London, but to my surprise, every one of the wifi points I can see in the area (30+ from my house, about 100 between here and the station) are now WPA2, with the exception of the odd BT public wifi, and a few BT-FON connections (I assume those also work with a landing page). There's not a single WEP or WPA to be seen.

    The area has a fairly transient population, and so I'd assume a high rate of turnover with ISPs, and I'm wondering if the reason is that ISPs have now largely 'got it', and are sending out new routers pre-configured to WPA2. BT in particular got badly bitten on wifi security a couple of years ago, so maybe they actually learned the right lesson for a change.

  14. bod43

    "29.5 per cent were using either the insecure Wired Equivalent Privacy (WEP) algorithm, or no security encryption at all ... A further 52 per cent of networks were using Wi-Fi Protected Access (WPA)"

    I find that very hard to believe. In the places that I go there are no WEP WiFis at all. Everything is WPA2, or is deliberately open. FON, BTOpenview etc. I have occasionally made a point of noticing.

    For years all new home routers have been set up for WPA2. Many people seem to change their ISP quite regularly and have new routers.
