This is a huge misconception about GenZ. Unlike Millennials and GenX who had to hack around on PC's to figure out how to torrent, run games, build our own lans for local multiplayer, and generally avoid our parent's prying eyes. GenZ has grown up on devices. You don't modify the OS on devices. You don't hack around on devices; Apps tend to just work with little configuration. GenZ is entering the workforce with lower baseline computer / computer security skills than people think they have.

Same I just was talking with my daughter (16) about this because she hated her intro programming class in high school. No biggie if it isn't for her, slightly disappointing that I can't share knowledge, but she should pursue what she enjoys.
What irked me was she claimed "I just hate being on the computer", but her screen time on the phone easily crests 8 hours daily. Maybe we are just entering a similar phase to auto mechanics. In the 1950s anyone who owned a car was at least somewhat proficient in its inner workings, now many people need to consult the manual to figure out how to pop their hood.
drivers99
There's a reason for that. I ran across a video recently that talked about how his dad would replace an engine over the weekend. But then he showed what the old cars looked like under the hood (very simple with lots of empty space) and new cars (very complicated). More importantly, he showed the manuals that came with the car. The old car's manual showed how the engine was put together and explained what everything did, and how to rebuild it. The new manual was only full of warnings and told you to take it to the dealer for everything.
Think about how I (and probably you) learned computers. My IBM PC has a manual that has a page just to show where the power switch is and how to use your hand to flip it. It has a diagram for what the keyboard cable looks like when it's plugged in correctly. It continues on and on and tells you how to open it and what the dip switch settings do. People always thought I was a computer wiz kid when I all I ever did was read the manuals and try out what they said.
noduerme
That's a fun analogy to think about. One side of it holds up: People don't know how to pop their hood now because they don't need to.
But on the other hand, cars before the 1990s were infinitely simpler to grok and to fix than modern vehicles. The learning curve was much gentler, and really no specialized knowledge was required. Changing the timing on your engine was easier than putting together an Ikea cabinet. Now it requires specialized equipment.
The opposite is true of computers. It has never been easier to snap together a cross-platform app to do almost anything than it is today. Friendly scripting languages, APIs for access to every kind of sensor and data imaginable, and devices fast enough to run terrible code at reasonable speeds. Almost everything you would have had to do from scratch hand in the 1980s has been done for you; a huge amount of coding now is just plug and play. And basically everyone in the first world has access to the necessary equipment to write their own code.

Sorry to be the bearer of bad news, but auto manuals haven't included such technical information for close to two decades.
forgotoldacc
I never thought about that, but it's true. My dad and every guy his age in my hometown can talk about cars nonstop. They'll go on for hours about changing the oil, messing with the transmission, or whatever (I don't know what they're saying--I'm a millennial and I'm used to vehicles that Just Work™).
Meanwhile, my friends and I can go on about the most banal computer stuff and my parents have no clue what we're talking about or why it's interesting to us. Kids probably don't either.
freddie_mercury
I saw someone joke that there's only one generation in the history of mankind that knows how to set the time on a microwave. Our parents couldn't do it. And now our children can't do it.
Cthulhu_
We won't be able to do it either soon, as they will mandate connecting with it through an app and we're like fuck that. (if we're not already there)
jwiz
I have heard that told with “VCR” in place of microwave. We still have a microwave that needs clock set when power fails. We do not have a VCR.
Terr_
[Millennial take] When older generations say "the kids these days are so good with computers", it's because they are incorrectly inferring competence from confidence. In a way, the kids are more capable, but mainly because of attitudes rather than knowledge.
The devices the (grand-)kids are using are much more explorable and idiot-proofed. Nobody is going to make a single "dd" typo and erase their drive.
dijksterhuis
> Nobody is going to make a single "dd" typo and erase their drive.
Alas, how does one learn if one cannot dd the wrong hard drive, wiping all the films you've spent most of the summer illegally downloading at night because you only had a dial up connection at the time.
ksp-atlas
I mean, I'm considered gen Z and I've definitely dd-ed my fair share of drives...
jhbadger
Definitely. I recently taught a class with a practical computer component and many undergraduates seemed to have a hard time understanding where their files were saved -- even at a GUI level, not talking about the command line. But it makes sense if their primary tech experience was with phones and tablets. The idea of a file system may never have occurred to them (even if most phones and tablets really run a UNIX-derived OS behind the scenes).
tharkun__
So true. Fortunately I had my kids (well one of them anyway) recently complain to me about how their teachers "don't know anything about computers" and how they "cheated" by using actual computer software that was much better than the "mandatory to use" software on the school tablets.
Not all hope is lost.
Cthulhu_
> (even if most phones and tablets really run a UNIX-derived OS behind the scenes).
Key phrase being "behind the scenes", iOS completely obscured the concept of files to its users for a long time. I don't remember how downloading files off of a website worked though.
DaSHacka
It's unbelievably bad.
I know 3rd and 4th year IT/Cybersecurity students that don't understand how to ssh into servers and the different layers of the OSI model.
I hate to sound insufferable, but I really truly believe some people are just too stupid for this field.
I'm so sick of dealing with them.
Yay job security?

GenZ also grew up in an era where doing anything mildly interesting on a computer risks getting expelled and having the feds called. The shit I did to learn my trade as a kid would absolutely not fly today.
StayTrue
Yikes – this GenXer remembers being told the tools found in my account were grounds for expulsion but the meeting ended with employment.

In high school (2000) I had a course where I downloaded some (freely available) videos for my project. The wrong person caught wind and hauled me in under the computer policy that everyone signed that said “I promise not to download anything”. I made my case that it was 1) condoned by my teacher, 2) relevant to my project, and 3) literally going to websites downloads files (cookies were just stored in a folder back then, as well as temp files for caching) so everyone is in violation.
Had they actually found out about the fact that we bypassed security measures on a bootable CD-ROM that allowed us full system access, including a nifty Visual Basic launcher to install Quake and GTA, or that we figured out every computer used VNC and they all had the same password stored in plaintext in the registry (which we accessed via that bootable media), or that we figured out the same password accessed every networked printer in the county so we could print our school’s logo on that week’s rival school’s printers in barely off-white ink…they’d have had a good case.
jeffwask
The dark ugly places I travelled on IRC or BBS as a youngster. I saw a lot.
DaSHacka
Some can still learn in spite of that, however.
Arguably, that's even why some gravitate towards it in the first place.
RajT88
Well - kind of. PC gaming is bigger than ever before, and PC gaming was how a lot of my generation got into computers.
My nephew for a while was very much one of those "grew up on devices" kind of kids - until he got off of gaming on phones and tablets, and got a gaming PC. Now he's reading about technology and tinkering and stuff.
blueflow
Its not the same. Nowadays you press a button in steam and the game is installed for you and just works. It does not provide an entrance into technical layers like configuring the soundblaster irq in config.sys did.
starkrights
I've seen both sides- my nephew is large into pc gaming, but is woefully unaware of how to operate a computer in most capacities. I only realized this when trying to help him troubleshoot and realizing he didn't really understand the concepts of archives or even folders.
I don't even know how that's possible because he plays modded versions of some of his games- how you get by without knowing what a zip file works at the surface level is a mystery to me lol.
bombcar
I don't know if it's a "uses tech" issue or just not realizing the steps needed. Even we knew you had to go to the campus gate to meet Dominos after dark (when the gate would be automatically closed).
There was no fancy intercom ability to remotely open it.
giancarlostoro
I realized this while working as a tutor for programming students at my college back in 2013... When people would ask or say they didn't know or understand really basic computer things (I can't remember what it was) I still showed them what they were, but I realized, not everyone grew up with computers the way I did. Some explore, but most people don't necessarily explore.
I think people who grow up with computer games have a lot more exposure than normal users. Smartphones somewhat made computers irrelevant for most people.
lynx97
Ahh, the modern verson of the written note under the keyboard...
In my area, there is a universal access key (physical) for postal service and newspaper delivery people. So if you want access to a random building, all you need to do is apply as a newspaper delivery guy, or, find one that is willing to give you that master key. To add insult to injury, that type of job is extremely low paying, so much room for abuse.
Fact is, locks and closed doors are there to make the owners feel cozy and safe. If you ever needed a locksmith service and watched them do their job, you know your appartment door is just a prop.
evilduck
You can just go over to Amazon, search for "pentesting keys" and for a the price of a decent dinner you can order oodles of master keys for most everything out in public. Elevators, police and fleet cars, mailboxes, file cabinents, RV external storage compartments, lift gates, tractors, electrical panels, toiler paper dispensers, etc.

When I lived in town, on a street that was somewhat common for people to walk down, twice (that I know of) someone had walked up, tried to open my door, then walked off after finding it locked. The amount of work to break into that house was quite minimal, but apparently a locked door did help.
gosub100
That's not true. They raise the bar above the bare minimum. Lots of crimes are ones of opportunity. A gate is the difference between 0 effort and some effort. It makes it a bit harder for a petty thief to cruise through and find low hanging fruit.
kleiba
Also for insurance.
It doesn't matter if it took a guy 10 seconds to break your lock, if you didn't lock your house, chances are your insurance won't pay.
lynx97
I didn't propose to leave your door unlocked. It was a cynical take on how much hurdle most locked doors are when someone is determined to get access. Maybe I am that cynical because I attended a lockpicking tutorial once (CCC Camp summer 2003, fun with tech at 37C temperatures, good old times), and as a tech person with some interest in security, learnt my share about social engineering (mostly to pretect myself).

Modern apartment building. Low rise. Full visibility of courtyard. Cycle gone missing with a baby seat attached. Nothing anyone can do about it. How did they get the key, who let them in, how did they manage to pry open the lock in full visibility? I was seething for a week. But somehow I knew this wasn’t really that big a security challenge for the thief.
WalterBright
I bet you could examine the keypad for wear. The worn keys (or the shiny ones) are the ones for the code.
In the days before cell phones, a burglar alarm would dial the alarm company. The phone company likes to install the phone box on the outside of the building. The alarm is defeated by an axe to the cable going in the box.
I had a fight with the phone company at my house, as I wanted the box on the inside rather than the outside. They finally agreed on the condition that I maintain the wire to the box.
These days, of course, the alarms use wifi or a cell phone to call the alarm company.
blacksmith_tb
That only works if there's a single code? I would think many keypad systems assign a code to each apartment (so the one written on the side is not a master key, just Joe in #303).
dmurray
I've definitely worked somewhere they tell all the users they have individual codes, not to share them, and if there is unauthorized access it can be traced who leaked their code. Everyone gets told the same story and given the same code.
mattlondon
Do your alarms not have an actual - you know - alarm? Or won't the alarm go off if it can't phone home first?!
Here in the UK the alarms make a noise as the absolute minimum. Getting one that is "monitored" by a call center is not standard, especially one that calls the cops if it goes off or a panic button is pressed.
You can get those of course, but it costs extra. I pay something like £40-50 a month for the panic button service that will summon the police, but even then the police won't be summoned if just the alarm goes off without a panic button getting pressed (you can get that, but it is even more expensive)
walthamstow
In my area of London, burglary is a virtually abandoned trade.
Anyone with anything of value works from home at least part of the week. Why risk entering someone's actual house when you can make easy money on drugs, fraud, crypto, bicycle theft, phone snatching, or umpteen other hustles I don't even know about.
Bicycle theft especially. You could easily clear a grand or two a week with zero fear of prosecution.
bell-cot
> These days, of course, the alarms use...
And the crooks use RF jammers instead of axes.
miki123211
There's enough bandwidth to go around nowadays that alarms can send regular keepalives (which doesn't mean all of them do).
If the keepalives stop coming without a proper disarm signal, a fault is raised.
Some old alarms had a weaker version of this, where they would dial the security company whenever the door was opened, and then again when the alarm was disarmed. If the second call didn't come in time, the company would instantly know that something was up.
This protected against thieves that would enter the house and smash the alarm before it had time to activate.
EGreg
These days, alarms use quantum entanglement. Beat that :)
sidewndr46
It's far simpler than that. Ever gated community I've ever visited, press any digit 4 times. You're in. The only exception is community with a security guard. The guy obviously isn't just going to let some guy not on the guest list in
adamanonymous
Gated communities around me have 2 lanes, one with a sensor activated gate for residents and a guest lane next to the guard hut
If it's busy and you pull up in a nice enough car and just wait in front of the sensor gate looking annoyed, the guard will eventually just let you in
renata
911 or 9911 is usually a good shot too.
wildzzz
There's a door at work I regularly need to access. It used to be used for another purpose but now is just an extension of the work area. It's got a badge reader and simplex lock but I can't get badge access because I don't actually belong to that work area yet I'm there everyday anyway. However, someone wrote the simplex lock code on a sign in very small numbers for this exact purpose. Other simplex locks in the building use the default code you can find online. The whole building is secure so you'd never be able to walk up to these doors without proper credentials, they are mostly just there to keep out the curious or someone looking to borrow tools that they shouldnt.
atlanticaccent
> The whole building is secure
Given what you just said and the article you're commenting under, are you sure?
organsnyder
Anyone wearing a maintenance uniform and carrying a step-ladder could surely find a way in via an overly helpful victim.
paxys
The point isn't really for these communities to be Fort Knox. It is understood that if someone really wants to get in they will get in, similar to how if someone really wants to break into your house they will do it regardless of what brand of lock you have on your front door.
People live in gated communities because of what the gate represents – a very clear sign telling you and everyone else passing by that you don't belong here.
null
imadethis
In a similar vein, 0911 or 9111 will often work too for communities in the US. EMS and other first responders run into the same issue with automated calls or panicked people, so they’ll try that first while waiting for dispatch.
That code was also used at our (EMS) depots to secure the controlled drugs as well, as if none of us could have guessed it.
_fat_santa
My parents live in a very upscale country club community down in Florida and their gate security is laughable. They assign every household a 4 digit code to enter the community. Given how many homes are in this community, entering any 4 digit code > 1000 and < 2000 will work.
jimt1234
My girlfriend lives in an upscale, gated community. Her HOA has done the exact opposite. They change the gate code weekly as way to "protect" themselves from this situation. However, it's kinda had the opposite effect - tailgating has become totally acceptable, even the norm, as people can't keep up with the gate code changes. Amazon drivers usually just sit outside for a minute or two, then tailgate into the neighborhood.
reaperman
The only gated community / apartment complex's I've ever seen where that was not normal are a subset of the ones that have an on-duty guard - specifically the subset with guards who recognize all the occupants and take the information of anyone they don't recognize.
bell-cot
They're doing a great job of "protecting" themselves from feeling anxious about Bad Things somehow happening.
For an all-too-large fraction of humanity, that's the "protection" which actually matters.
zbrozek
My townhouse HOA decided it was totally worth money to replace our fob system with a system that's deliberately incompatible with Homelink. They claimed without evidence that used car sales were a severe security risk.
Nevermind that you can wave any conductor under the gate to trigger the egress wire loop sensor, or just wait a minute or two for someone else to go through. From 6AM to 10PM the other gate is simply open, too.
Now I have to pay more for crappier fobs with worse range. It's deeply disappointing.
bgirard
> Hirsch replies stating that these vulnerable systems are not following manufacturers’ recommendations to change the default password
These manufacturers’ recommendations are not acceptable. They should mandate a non-default secure password before allowing the system to be used.
pavel_lishin
Even my parents & grandparents modems/routers each have a unique password printed on the bottom! There's just no excuse for this.
robbiewxyz
Their routers only have this feature because the internet providers who sell those routers pay for bandwidth themselves lol. If residential internet plans sold on a pay-per-byte basis you can bet routers’d still ship with non-unique passwords.
schnable
Nah, it's to deflect customer support contacts. Which often in the case of ISPs, results in a truck roll which is hugely expensive.
jonathantf2
It's also the law in the EU.
prophesi
Oddly enough, these default unique passwords usually are in the format of word+word+digit+digit+digit. If you look up the model, it won't take long to find the word list they use and can trivially bruteforce it.
So even then, I'd recommend changing it, or push for these companies to provide generated passwords with a much larger key space.
Semaphor
German fritzbox routers (the most common non-isp routers here, and actually very capable) have a fully random password
jack_pp
Idk in Romania routers come with random passwords.
bongodongobob
That's usually the wifi password, not the admin password.
nottorp
Oh speaking of which. A lot of places i rented on holidays had internet access with that default unique password. Which is a pain to type on your phone and laptop when you get there.
Did anyone think to at least try to add OCR-ing those labels on our phones to automatically enter the wifi password?
happyopossum
>Did anyone think to at least try to add OCR-ing those labels on our phones to automatically enter the wifi password?
You can do that easily on iOS, I'd be surprised if Android didn't allow it as well...
Tap in the password field, tap Autofill from the popup, and tap Scan Text.
ghaff
A lot of inns and B&Bs in tiny towns etc. have these complicated passwords that seem like overkill. You're probably right that they're some sort of default. Even if they're not 12345, it seems as if they could be something pretty simple and that would be fine.

Viscount has hilariously bad security. I used to live in a building in Toronto that used Viscount infrared fobs for access control. They were no more secure than TV remotes; no rolling codes, no encryption, nothing. An attacker could easily sit nearby with an IR receiver and collect everyone's fob codes at a distance, allowing access to all floors.
Needless to say, I moved.
prometheus76
This was 30 years ago, so I'm sure a lot has changed since then. I was a missionary and the way we got into buildings in Toronto to knock on doors was to just pick the last name with the most letters from the directory, buzz them, and when they answered, we would just say "pizza delivery" and 95% of the time they buzzed the door open.
nosioptar
It'd be nice if missionaries weren't such hypocrites. Claiming to be the pizza guy when you're actually selling magic underwear is bearing false witness.
roguecoder
Technically it depends on the interpretation of "עֵ֥ד" and "בְרֵעֲךָ֖" whether that commandment is admonishing against telling any lie, just lies in court when making a legal accusation against another person, or somewhere in between.
Even if we accepted the premise that one book should be the basis of all morality, this one contains within itself contradictions, satire, sarcasm, and a community context we no longer have: with individual quotes I can make anyone look like a hypocrite.
To my mind the more interesting question is, does a singular community condemn a behavior in out-group members that they tolerate or even praise in in-group members?

Yes. I'm no longer a Mormon, but I baptized around a dozen people on my mission and they were all found from knocking on doors. But this was also thirty years ago, before the internet was a thing for most people.

I'm not going to especially defend but you have a way more sophisticated model of how most burglars work than is almost certainly the case.
reaperducer
Exactly. This article should be titled "I figured out a really obtuse way to break into apartment buildings."
A rock will get the job done in a fraction of the time.
It's like all those nobodies on HN who go through all kinds of software gymnastics to secure their phone against imaginary "threat actors," when a mugger is just going to keep twisting their arm behind their back until they enter their PIN.
badgersnake
This is way better than a rock. It raises no suspicion and leaves no trace. Maybe it doesn’t matter for burglary, as you’re probably going to take things anyway, but if you want access anyone knowing you were there this is gold.
Neonlicht
In fairness I think that these "locked doors" are to keep the homeless/drug users out or kids starting fires not really burglars.
ghostpepper
In a lot of modern buildings the elevator will not let you up to any floor unless you've been admitted, so the rock won't do you much good unless you also use it to smash the lock on the elevator control panel and override the security there.

> infrared fobs
Wait, what? You have to point a powered device at an IR receiver and press a button like a TV remote? I've never seen a building entry system like that!
psobot
Exactly that, yes! IR receivers outside every exterior door to the building, and IR receivers in the elevators to control access on a floor-by-floor basis.
The fobs were visible by an IR camera (including the average smartphone) and could trivially be decoded as a short bit sequence with an IR sensor wired into a microphone jack, as the bit pattern was transmitted at ~audio rates.
__MatrixMan__
That's probably because it's not so good as a building non-entry system.
malaya_zemlya
There was a time where somebody in SF has figured admin access code to older apartment intercoms (I believe they were manufactured by Linear and maybe other companies too). These intercoms would call the programmed in phone number whenever you type in the apartment access code at the door.
So what they did is add a new fake tenant with a premium 1-900 number and used the intercom to call it, earning themseleves a bit of cash. Naturally, landlords had to foot the bill.
ediwdlrow
That sounds like a fairly open/shut case of fraud/abuse if it can be proven.
At my last apartment my LL would only allow a single number per apartment... well I was sharing the apartment with someone else and I was sick of being the only person to get called. 30 seconds of Googling revealed the user manual for the intercom, and of course the default password of "5555" was still set on it...
I programmed both our lastnames and phone numbers to our apartment unit number. I did that in 2014 and I moved out in 2016.
To this day -- NINE YEARS AFTER MOVING OUT -- I am still getting calls whenever someone hits #25 on that intercom.
I should have done the 1-900 thing :D
gosub100
I did something similar to my highschool in the 90s. They had a free student phone in the office. It had long distance blocked on it, but I learned you could circumvent the block using those 1010-321 and other long distance prefixes. Some of them had $5 access fees, billed once, in addition to the per minute rate. I called several of these and prided myself on getting the phone removed from the office for a few months.
fourteenrhinos
Can you elaborate on why having the phone removed was itself a source of pride?
I do appreciate the hacking around aspect, particularly with respect to old phone systems, but having a free student phone removed seems like it would be a bad thing for everyone, no?

I was a rebellious teen. I'm not proud of it now.

Breaking the rules so bad that the ability to even interact with the thing the rule was made for was taken away?
miki123211
The Polish spin on this were unsecured office landlines that used radio for some reason, I don't remember if that was for cordless handsets or just an access technology.
People would walk around big cities, usually on Friday evenings, radio scanner out, trying to find one of these. They would then dial a premium-rate number, preferably on more than one line. In most cases nobody would realize that something was up until Monday morning, and if they had a way to disconnect the calls before then, not until the bill came.
You could do similar shenanigans with unsecured PBXs or insecure answering machines that had a "call my mobile if somebody leaves a message" feature.

Ah, yes. It's the children who are wrong.
0xbadcafebee
This is the kind of thing where responsible disclosure is really very important.
Let's say you're a woman. A woman who lives in one of these apartment complexes. A woman with a stalker. A stalker who has threatened to kill you, multiple times. Who has shown up at your apartment, but was rebuffed by the building security.
One day you wake up and find out that a "security researcher" found a way that anyone in the world can get into the building at any time, in addition to looking up who lives at each address. And it turns out the security researcher waited only two months (including over christmas break) to try to resolve the issue in a way that would not leave the existing buildings exposed.
If I were that woman, and something happened to me as a result of this disclosure, and assuming I was still alive, I would, at a minimum, sue the shit out of that security researcher.
Lanolderen
Tbh if someone's determined to kill you, enough to look up CVEs and so on on your security system, they might as well wait by the door to brick you in the head when you inevitably come out. It's even better for them since you're bound to be less armed than at home surrounded by kitchen knives, tools, chairs, etc.
autoexec
> assuming I was still alive, I would, at a minimum, sue the shit out of that security researcher.
If you wanted to stay alive you'd be wise to think twice about going after people who go out of their way to inform you that the security you are dependent on is not doing its job. You'd be much better off instead going after the company who was negligent enough to create the system with such obvious flaws or the landlord who subjected you to it without even bothering to read the manual.
The alternative is that researches will stop telling the public when they aren't safe and you stay ignorant while some attacker spends the 15 minutes it takes to find and try the default password.
The person who disclosed this was right to get the information out as widely as possible as quickly as possible because, as you said, some people are likely depending on those locks for their safety. Thankfully everyone who learns that this product has made them vulnerable can now take measures to protect themselves accordingly.
We'd probably agree that there could have been better ways to disclose this, ways that made it instantly clear that this product was putting people in danger, while also not making quite as easy for others to repeat the attack, but in this case you can bet that trying the default password was going to be high on the list of things people would try anyway. I think it's extremely unlikely that this security researcher was the first it.
The most important thing is letting as many people as possible learn about their risk so that vulnerable people can protect themselves ASAP and so that the negligent company/landlord feels a lot of pressure to fix the situation as quickly as possible. If you make security researchers think twice about doing that you'll only allow yourself/others to come to harm. Ignorance really isn't always bliss.
4gotunameagain
First of all there is no need in pointlessly gendering the risks involved.
Secondly, if a person is determined enough to look for vulnerabilities in the access control system, they are determined to do much more.
Thirdly, public disclosure more often than not leads to enhanced security down the line, protecting both men and women alike.
inetknght
I'm disappointed you're downvoted. I know a woman who is the exact situation you describe (sans hacker); their ex-husband has made threats to her life and has made attempts to act on those threats. She's extremely privacy sensitive as a result.
You are right. But remember you can be sued for anything, and further remember that suing someone doesn't mean you have good cause to win.

So it stands to reason that a white hat hacker who, in good faith, publicly releases information in an attempt to get things fixed shouldn't face negative repercussion.

But they should face consequences if they were irresponsible, regardless of intention.
If you found the nuclear launch codes, and you're pretty sure nobody else has found them, should you wait a week and then release them, because you had a good faith interest in exposing this hole? No, of course not, that'd be insane. What one should do in that situation is wait, and try to get the codes changed. You shouldn't wait forever, because someone else might find them. But you also should wait for as long as you reasonably can, because of how severe the risk of releasing is.
This risk analysis is the calculus of responsible disclosure. Any ethical security researcher should err on the side of avoiding harm, making every effort to ensure the disclosure doesn't harm unnecessarily. For most researchers, that means waiting more than 2 months over a holiday season, even if it was just a bug in a javascript library or something. Knowingly exposing the privacy and security of thousands of people is pretty fucked up, imo. I'm pretty sure they could have come up with a half dozen different ways to try and get the issue resolved, if not through the company directly, then through individual apartment complexes, law enforcement, etc.
Looking at this closer, it's actually worse than I originally thought. You can see what time everyone comes home every day, what their weekly routines are. So you know when they're gone, so you can rob their house. Or you know when they come home, so you know when you can attack them. This is fucking chilling.

The author contacted the current and former vendors, got a flippant answer, asked again, and was ghosted for two weeks.
I see here a desire for a random person to accept a staggering amount of your personal responsibility. Anyone under long-term active threat without defense-in-depth redundancy isn't someone I can save by waiting longer before disclosure. I am frankly amazed you expect so much from a stranger for so little benefit.
It is fucking chilling -- that the publisher would do this, in the first place, and blow him off now, too.
Why don't YOU pick up what you said, and start contacting apartment buildings and police? How many of those half-dozen ways you mentioned will YOU act upon?

> But they should face consequences if they were irresponsible, regardless of intention.
Intention is important.
If their intention is to highlight that a problem exists, then sure. They should be forced to participate in resolution (at the very minimum). As for liability? No, that definitely belongs on the owners of the insecure devices.
If their intention is to show to "the bad guys" where the spots are vulnerable? Then yes, they are partly culpable.
Again, being a good samaritan (showing that a problem exists) should NOT make you liable for the problems that already existed.
> you also should wait for as long as you reasonably can
That word, "reasonably", is loaded. I think waiting a couple of months is perfectly reasonable when being stonewalled by other parties, especially the owner.
> that means waiting more than 2 months over a holiday season
Yup, sure, because thieves definitely don't operate during holiday season. And please ask Russia and the US to hold off on their nuclear war. It's called Nuclear Winter, but that doesn't mean it has to happen during Winter, right?
> This is fucking chilling.
The problem existed before the announcement was made. You think it was chilling before? Just imagine that nobody who was capable of fixing it didn't know about the problem. So it could be abused without anyone being the wiser. That is fucking chilling. It's chilling that people would be more upset about the announcement and less upset about the apartment building owners not fixing the problem in the first place. That is fucking chilling.

Many many many years ago I worked at basically an MSP for telcos on the helpdesk. So customers would call their telco or isp for help and that would be routed to us. Anyways this one small isp with idk 10k customers had deployed their routers to customers with the default username/password and remote authentication enabled. A single script from a bad actor logged into all of the routers, changed credentials, and iirc updated dns settings so they lost internet, phone, tv. Cue 10k people calling as we had to basically walk through everyone one by one on changing the credentials and updating their config.
myself248
Was that enough pain to force some sort of change in how the things were deployed thereafter?
ecshafer
Sort of, they changed it to a different username password that was the same on every box. So it wasn't easily findable from the internet but the same issue could have potentially happened again.
Agingcoder
After watching a lot of tv series, my non techie wife has come to the conclusion that real life systems are trivial to hack : just click ‘skip password’, or ‘password override’, or just use ‘password’ as a password.
It seems she’s almost right !

I’ve always wondered: how do all these things end up in Google? What’s submitting the link, or public thing links to it?
userbinator
Google's own browser phones home with the URLs you put in it, presumably for malware scanning or some other "security"-excuse reason.
I don't remember if there was a setting to stop that from happening, or if there was, whether the setting may still exist today, but that would be a good way for them to get otherwise-private URLs.
MBCook
That’s all I can think of. That or perhaps emails (in gmail or another web mailed viewed by Chrome) that contained the links.

Breaking into an apartment building in 30 seconds without a phone:
Carry a brown paper (food delivery) bag. Stand by the intercom pretending to press buttons. When someone comes in or out, tailgate behind them and say "thanks". 9 out of 10 times they'll even hold the door open for you.

> Default credentials that “should” be changed, with no requirement or explanation of how to do so. Surely no building managers ever leave the defaults, right? And even if they did, they’d surely have no reason to expose this thing to the Internet, right?
My theory is this is one of the reasons so many internet-of-things devices nowerdays omit any sort of offline/local network control.
No default passwords, no ports you can forward without knowing what you're doing, all the credentials sorted out on a cloud server.
craftkiller
Consumer routers have had this issue solved for ages: you generate a random password and put it physically on the device.
ghaff
I don't want some complicated random password. At least where I live, my router password is a very modest security shim to protect against very random casual access. If I have a visitor who needs WiFi access, I want to give them an easy password to type in.
marsovo
So change it afterwards. Good defaults are important. If someone doesn't change it, it's important that they be on the right path instead of...this one.

You can always change the passwords. I was bringing this up as a solution to the default passwords issue. You don't want to have a static default password used by everyone, so you need the initial password to be randomized. People are dumb so you need to print it on the device. There is no need to default to cloud-based authentication to close the default password security hole.
wlesieutre
If it's too hard for a guest to type in a password, you can also have them join by scanning a QR code. Obviously this works better for phones and tablets with QR scanning built into the camera, but that's what guests are frequently using.

Wifi password != admin password. The admin password should be random and then you can change it when you take ownership of the device.
inetknght
> I don't want some complicated random password.
It doesn't have to be complicated. A random passphrase can be much simpler and include significantly more entropy: four to six words plus a six-digit number. Any password generator worth a damn can generate something like this.
huang_chung
OpenWRT, the crown jewel of open source firmwares for "insecure" consumer routers, uses a blank (null) password by default with full root access.
dylan604
No device comes off the shelf with OpenWRT. If you're the type of person that's aware of OpenWRT and then install it, it's not that far of a stretch to think you'd also be the type to know to check the password.

i worked as an engineer in an industry that required on-site access to buildings all over manhattan, some residential. all you have to do is hit a couple random buttons on the intercom and 100% of the time one of them would just buzz the lock
mvandermeulen
This is pretty much all it takes in any western country. Some areas might require a little more effort but nothing substantial.
In fairness, the blame for this kind of enabling attitude is mostly attributable to me locking myself out of the building and having to buzz my long suffering neighbours at all kinds of ungodly hours. Proud moments.
megous
Could you also lock out specific residents? Or get their daily home arrival patterns for the last few years? Or find unused flats to squat in? IoT still wins. :)
Road with a guy to visit a friend in a gated community. We didn't know the access code for the gate but the guy I was with is an Amazon delivery driver.
"Let's see if I can't get us in," he said. He got out of the car, walked over to the access panel and looked on top, bottom and sides. Then he punched in some numbers and the gate opened.
Turns out, so many people in gated communities and apartment complexes order things from Amazon, and other delivery services, and want front door delivery but don't give them any way to get in. Eventually, some frustrated driver who gets the code will write it on the side of the access panel to help everyone out.
"Apartments are awful," he said. "College campuses are the bane of our existence. You would think that college kids would be smart about these things but they are the absolute worst."
