From my experience, non-tech people just leave browser defaults. I'd argue this is better than letting them to use public wifi without VPN. If you really care about security you won't use it, of course
- dataflow 4y agoPublic Wi-Fi in the world of HTTPS is not exactly terrifying.
- gambiting 4y agoHTTPS is trivial to break with a man in the middle attack, yes you get a scary warning in your browser about an invalid certificate, but I'd bet that 90% of people will just click through it and ignore it.
- shepherdjerred 4y agoI highly doubt this prediction is accurate. Most people will think something is broken and call tech support. Aside from that, this isn’t possible for HSTS sites.
- gambiting 4y agoReally? Most people? I cannot think of anyone from my family who would even think about it for a second - they would just get annoyed they can't get to their bank website or whatever and just click continue. Also what tech support? Me?
- elcomet 4y agoBut now there is no button "continue", you have to click multiple buttons, which are not clearly labelled, in order to see the page. I'm sure 90% of people would not even be aware that you are able to continue. Even more, for self-signed certificate on chrome, there is no button to continue for example. Check https://self-signed.badssl.com/ https://self-signed.badssl.com/
- gambiting 4y agoIn your example, all I had to do was click advanced then proceed(Chrome on Android)
- elcomet 4y agoOk, on chrome desktop there is no way to bypass the security
- not2b 4y agoYes, there is. I often have to use it to deal with some internal misconfigured site inside the corporate intranet (the cause is almost always that a certificate has expired, when it isn't it's because a host can be reached with two names and the cert matches only one of them, but that case can be fixed by using the proper URL). I have no trouble telling chrome desktop to bypass.
- sbierwagen 4y agoHSTS cannot be overridden. Which bank domain names are you thinking of that are not one of the twelve thousand names on the HSTS preload list? https://source.chromium.org/chromium/chromium/src/+/main:net/http/transport_security_state_static.json https://source.chromium.org/chromium/chromium/src/+/main:net...
- LtWorf 4y agoI tried 5 banks (swedish and italian). None of them are in the list. I feel safer now :D :D :D handelsbanken.se danskebank.se unicredit.it fideuram.it sella.it
- sbierwagen 4y agohandelsbanken.se is on line 163144. (I was a little bit off on the length of the list before) unicredit.it is not on the list, but unicredit.ba and unicredit.ro are. (Lines 7331 and 7332) It does send HSTS headers. danskebank.se and sella.it are not in the file, nor are the base strings, but both sites do send HSTS headers. fideuram.it is not on the list, and does not send HSTS headers, so they don't seem particularly interested in security. They also haven't set an A record for the root domain, so visiting `fideuram.it` returns NXDOMAIN. Only `www.fideuram.it` exists.
- LtWorf 4y agoSo this shows that your statement about the security of hsts headers was overblown?
- sbierwagen 4y agoYou got me. I wildly overestimated the competence of Eurobanks. I'll never make the mistake of assuming an institution knows what it's doing again.
- LtWorf 4y agofideuram removed the phisical tokens for 2fa and moved to SMS, saying that it was because of some european directive… I went to read the directive. It basically said to not use sms and avoid apps in favour of dedicated 2fa devices for banking.
- shepherdjerred 4y agoFrom my experience working as on-campus tech support in college, most people who aren't tech savvy will quickly give up or look to someone else for help. They will likely not think to click Advanced -> Continue Anyway (unless they have been taught to do that before). Tech support comes in many forms. The owner of the website, a friend who knows about computers, someone else in the workplace, the vendor they purchased their laptop from.
- hsbauauvhabzb 4y agoHsts solves sslstrip, I do not believe it enforces cert pinning. Iirc browsers deprecated cert pinning some time ago.
- shepherdjerred 4y agoI've seen HSTS not let me continue without the server having the expected certificate recently, so I think that's still a thing.
- mr_toad 4y agoThat might be because of certificate transparency rather than certificate pinning.
- 1vuio0pswjnm7 4y ago"Aside from that, this isn't possible for HSTS sites." Isn't it possible for the user to disable HSTS. A simple web search produces detailed instructions, from a CA. https://sectigostore.com/blog/how-to-disable-hsts-in-chrome-firefox/ https://sectigostore.com/blog/how-to-disable-hsts-in-chrome-... Also, what does "HSTS sites" mean. Does it mean (a) "official" HSTS via HTTP header alone, (b) "unofficial" HSTS via preload list (see RFC 6797 section 12.3), i.e., the list maintained by Google, hardcoded into a browser, or (c) both. The "unofficial" approach only seems feasible for a limited number of domainnames and unworkable for every domainname in existence. In tests I have done on Chrome (YMMV), executing "Clear site data" via Developer Tools, or including Clear-Site-Data: * in an HTTP response header, e.g., added via a user-deployed proxy, will clear an "official" HSTS block, allowing the "MITM" to proceed. Besides being generally annoying, HSTS allows for setting "supercookies" that persist even in "Incognito" mode https://nakedsecurity.sophos.com/2015/02/02/anatomy-of-a-browser-dilemma-how-hsts-supercookies-make-you-choose-between-privacy-or-security/ https://nakedsecurity.sophos.com/2015/02/02/anatomy-of-a-bro... The RFC for HSTS even admits how it can be used for web tracking. Not too concerning for the advertising company sponsoring the RFC. 14.9. Creative Manipulation of HSTS Policy Store Since an HSTS Host may select its own host name and subdomains thereof, and this information is cached in the HSTS Policy store of conforming UAs, it is possible for those who control one or more HSTS Hosts to encode information into domain names they control and cause such UAs to cache this information as a matter of course in the process of noting the HSTS Host. This information can be retrieved by other hosts through cleverly constructed and loaded web resources, causing the UA to send queries to (variations of) the encoded domain names. Such queries can reveal whether the UA had previously visited the original HSTS Host (and subdomains). I use a loopback-bound forward proxy to enforce zero tolerance for HTTP across all programs, not just the web browser. Everything is sent via HTTPS. The proxy is configured to to check certificates, and deny connections, according to rules I set. I use a text-only browser for noncommercial, recreational web use so I need a forward proxy, if for nothing other than to deal with the spread of TLS. But I also use it for a whole laundry list of tasks. Maybe it is just me, but HSTS, like much of Google's rhetoric, comes across as unfriendly if not hostile to proxies, regardless of who is running them. Consider this line from the RFC "The rationale behind this is that if there is a "man in the middle" (MITM) -- whether a legitimately deployed proxy or an illegitimate entity -- it could cause various mischief (see also Appendix A ("Design Decision Notes") item 3, as well as Section 14.6 ("Bootstrap MITM Vulnerability"));" "Mischief." Does that include inspecting one's own HTTP traffic on one's own network. How about blocking certain methods of tracking, data collection and advertising. Apparently it includes disabling HSTS. Let's be honest. Google is an undisputed king of "mischief". The stakes for Google mischief are much higher and there have been too many fines to count. Consider the latest. How many people deploying their own proxies get fined $4B. (Arguably, an issue of "control" was at the heart of that decision.) https://www.theregister.com/2022/09/14/european_court_fines_google_android/ https://www.theregister.com/2022/09/14/european_court_fines_... If the proxy is "legitimately deployed" then why not stay out of the network operator's way. Let them have control. Give the option to cede control to Google instead of making it a default. I use HSTS for commercial, nonrecreational web use, when I have to use a "modern" browser. That is a small fraction of total web use for me.
- ShinTakuya 4y agoI'd argue the invalid certificate would only get the middle segment of semi-tech literate but security illiterate people. So maybe a lot of people on this site . The average user, based on my observations, tends to take these warnings very seriously.
- jiayo 4y agoHave you looked at what the UX is for invalid certificates in 2022? It's not like ten years ago where you just click enough times and "visit anyway". Here, try this link in Chrome: https://untrusted-root.badssl.com/ https://untrusted-root.badssl.com/. When you click Advanced, it tells you "the website sent scrambled credentials that Chrome cannot process". And beyond that there's just no button to bypass it. You can't visit the site. (Sure, there's probably a chrome://flags or --disable-web-security way to bypass this, but that's well beyond the average user's comfort zone, as well it should be.)
- gambiting 4y agoI clicked that link - in Chrome on Android all I had to do was click "advanced" then "proceed anyway". I have never changed any flags or default settings in this browser.
- 988747 4y agoI just tried to open the site in Safari, and there's no "Continue anyway" button, only "Go Back". I did not change any default settings, because I use Firefox as my daily driver ( and Firefox does have "Accept risk and continue" button, but I think the word "risk" on it is scary enough for many people to not click it). EDIT: It turns out there is a "visit this website anyway" option in Safari, but it is not a button, it's a link which you only notice when you click "Show details" button and read the warning.
- chrnola 4y agoA slight digression, but I read[1] recently that typing “thisisunsafe” while the tab has focus is sufficient for bypassing the warning.

- LtWorf 4y agoUh I just have to click "advanced" and then "proceed anyway". I tried on a blank profile to make sure there were no strange settings.
- fsckboy 4y agoit's not so easy to click through, because I often try and it really seems like they don't want you to, the dialogs are very confusing.
- gsich 4y ago>trivial >requires user mistake Not sure how that matches.
- gambiting 4y agoIt's trivial to set it up for the attacker. If you have a Linux laptop you can set up a redirect for all the traffic on the network through your machine with two commands, then there's plenty of tools that will intercept any incoming HTTPS certificate, replace it with your own, the decrypt the traffic. It sounds like a lot but anyone can set this up in about 15 minutes - that's why I said it's trivial. The user mistake is just clicking "advanced" then "proceed". I know all my family members would do that without questioning.
- gsich 4y agoMaybe teach them to not do that.
- CommitSyn 4y agoPlus, Firefox is soon implementing HTTPS-Only by default if I remember correctly. What was it, maybe 2016 there was a big push for SSL and the majority of the web, even login and payment pages, were HTTP? Now only a small percentage of the web isn't HTTPS. I have HTTPS-Only enabled in Firefox and rarely do I have to click the 'Continue Anyway' button to browse an HTTP page. For most general users that only use popular services, I'm sure it's even more rare.
- ct0 4y agoIts so easy, even a dummy like myself can grab a cert for my self hosted services. I dont give any HTTP only sites any slack
- b112 4y agoI have a site from 1997, pure html, with drivers, install disks, documentation for computers from the 80s/90s. It works. It's fine. No, it does not need ssl. What, someone is going to hack a floppy driver for a computer, which doesn't even have a built in network stack?! No, I am not going to do work on it, any work, at all. Millions of such sites exist, are fine, are safe.
- hcrean 4y agoIt is all fun and games until one of the downloads from your site picks up malware in transit and the user goes "why did this web admin infect my computer? Sue!" This genuinely happens a lot in the 2020s.
- mjevans 4y agoYou forget exactly how much the government felt they got out of just knowing whom was talking to whom, not even bothering to collect the data of the conversation itself.
- NegativeLatency 4y agoNow they only have to subpoena/hack/partner with microsoft for that
- somenameforme 4y agoMicrosoft was one of the first companies to sign up for PRISM [1], doing so in 2007. I think there's a subconscious feel among many that because the media stopped reporting on these things, that it stopped happening. PRISM never ended, and almost certainly has only expanded and grown even more invasive and brazen largely owing society's apathy towards what Snowden revealed. Literally to this day one can read things like the NSA manual for using their software that enables real-time absolute surveillance of Skype: "User's Guide For PRISM Skype Collection." [2] The idea of any degree of privacy from any tech company hosted in America is a lie. The main difference with China is that we lie about our surveillance state, and force companies to lie about it, while China openly advertises theirs.

- samstave 4y agoPublic wifi and bluetooth detectors all over is whats scary, as most public wifi is used by phones, not machines and who the hell is running edge on their phone? but this just reminded me of the failed FB phone and the failed microsoft phone...
- dmix 4y agoWhat bluetooth devices are you concerned are going to leak private data? Looking at the ones I use daily... headphones, TV soundbar, Xbox controllers, TV remote. None of those provide an interesting attack vector. My iPhone isn't really going to be connecting to random stuff and leaking data, so I don't really see the risk here. Maybe I'm missing something?
- samstave 4y ago>>My iPhone isn't really going to be connecting to random stuff and leaking data Incorrect -- BT scanners and loggers have been LONG tracking your things avail... and the fact that Apple doesnt allow you to "turn off" it merely pauses.. both wifi and BT... they use prox sensors for BT for airtags, wifi etc and ALL OF THAT data in mined like mad. Any Apple person that says otherwise is lying to you.
- dmix 4y agoSo deanonymizing bluetooth device IDs. I know the Canadian spies used airport Wifis to deanonymize Wifi MAC addresses then set up wifi stations all over Toronto to experiment in tracking people. How would they do the same for bluetooth? Broadcasting "Dans iPhone" doesn't tell you much.
- samstave 4y agoCorrect, but its a more insidious web on this level... they have so many correlation engines for device location, that it will soon be impossible to be "off grid", if its not already. how the heck do you think there are fn leaks from over a decade ago of "text messages received by the government reveal that person X who is on the shit-list was quoted as saying [BULLSHIT] sources close to CNN have stated.."] ASIDE: Famous story from ~20 years ago was talking about the CIA handlers at CNN... and the revolving door of in-q-tel emps from fb moving back and forth within the security team (one of which had to be walked out of the building for [things]) you dont need "dan's phone" they have had eschelon for DECADES and were able to literally do 6-degrees ppl tracking since the 1990s... WTH do you think they named it "starlink" instead of sky-net... And when they built the first part, they were advertising the wonderful things the rural folks in africa's greater continent will benefit, then after a few years they showed that the system will primarily service the dense populations of the coasts of places like the USA and AUS -- which is where a big portion of the five-eyes service. IMEI and such is a bitch.. iOS is the biggest location tracking platform ever... Remember when the founder of Android (from Danger) was let go from google with a ~200MM$ golden parachute at $90MM to gtfo?
- snickerbockers 4y agoyeah but im pretty sure 99% of the population just clicks past those SSL certificate warnings, in part because they don't understand what that means, and in part because there are way too many sites that let their certificates expire.
- newZWhoDis 4y ago> Public Wi-Fi in the world of HTTPS Story time. Someone I know once got laid thanks to Facebook not encrypting their sessions My university was still using basic ass unencrypted WiFi with some kind of terrible dns-hijack sign in to “auth”. This of course meant that everyone put their shiny MacBooks on essentially public wifi and logged in to social media in the clear in class. Some enterprising chaps made a browser extension that made it trivial to snoop any open sessions and impersonate that session in a new tab. Someone I know would do this during lecture and post to people’s social media as them saying they should pay attention in lecture. Possibly some other scandalous things were said. The hilarity that led from that stranger doing so led to the beautiful nerdy girl sitting behind this person noticing and daring them to post more. That became hanging out, parties, and as far as I know they got married and have kids now. Literal people exist that wouldn’t otherwise because Facebook didn’t have HTTPS
- staticassertion 4y agoFuck, HTTPS was already popular by the time I went to college. That explains everything.
- newZWhoDis 4y agoTo be fair this needed HTTP and WPA(?) lol. Old school wifi let you see everything every other client sent.
- jcims 4y agoI credit the fact that basically nothing was encrypted over the wire when i got into computers in the 90s for learning how protocols work.
- Groxx 4y ago>Some enterprising chaps made a browser extension that made it trivial to snoop any open sessions and impersonate that session in a new tab. Firesheep was super big for a while, yeah. I used it to show a few coffee shops that yes, really, WiFi with a password of "password" was measurably better for their customers than no password: https://en.wikipedia.org/wiki/Firesheep https://en.wikipedia.org/wiki/Firesheep
- aeternum 4y agoYou can learn a lot about a person based on the IPs they visit. HTTPS/SSL doesn't protect you from that. In many cases you can even determine which protocols and general content they are consuming from that IP based on traffic shaping/fingerprinting. The burst of traffic your browser sends when loading a particular site is quite exploitable. There's plenty of software already available that makes use of this.
- sbierwagen 4y agoWhat percentage do you think of all network traffic that Edge handles is 1) Over wifi? 2) Over unencrypted wifi?
- itake 4y agoFrom my experience, tech people with non-default browsers can't use the internet :(
- kuekacang 4y agoWe had recently hired new programmers, 2 freshgrad and 1 junior. All of them use edge on their personal laptop and I didn't notice extension button anywhere.
