    ”Finally, the company should have enforced a strong password policy that would have prevented our heroes from finding dozens of accounts with “winter2023!” as the password.”

    Capitalize that “w”, and you’ve got a password that will pass most PWD policies. Why do they think it was “winter2023!” to begin with? In 90 days when the PWD expires, well, it will be spring of the next year, so…

    The better idea is to require passwords with some real entropy, and get rid of expiring passwords. It’s not 1999 anymore.

      1. Open a web browser and do a search

      2. Read until you find a sentence that you like.

      3. Use it as your password

The experience is so nice with key pair exchange for ssh. Its just that there i have thr security of knowing exactly where my secret is and how i can manage it, its just a file and i can move it like a file

                          Letting users pick their own passwords has always been a mistake. If passwords are needed, the system should choose them.

                                  Expiring passwords and length limits. Why can't my password be a 5KB long? My password manager has no limits. Are people storing them in plain text in 2026?

                                      And content limits. Why can't my password contain the % character? No special characters? What makes a character "special"? Why can't it contain emoji? So many password systems go to great lengths to remove potential entropy and randomness from passwords with their rules. The usual excuse is "blah blah blah legacy systems" which is not a good reason.

                                        Personally, I wouldn't use anything beyond ASCII in a password. I don't want encoding bugs to lock me out of my encrypted partition or bank account, thank you very much.

                                          Probably because there is some mildly decent reason (or very good, I don't know) to avoid them and it really doesn't matter enough to worry about getting around it.

                                          Why would you want emojis in your password? It's a piece of text not meant to be seen, emojis are meant to be seen. Just randomly generate some characters and get on with your life. I don't understand why you care about this at all, it's such a pointless thing to complain about.

                                            To me it signals bad engineering in the underlying system which doesn’t exactly encourage trusting the system with my data.

                                              I think simplicity is good engineering. Bending over backwards to support pointless usecases isn't good engineering. Almost nobody would use this and the ones who would don't need to. Why put in the effort?

                                            I ran into a website for work that would let you create a long password, but silently truncate it to 12 characters before saving. Mind boggling.

                                            • halJordan · 5 days ago

                                              This is the best. Especially when the password is being autotyped by the pw manager and so you never see the truncation and now have a bad pw saved in your manager. Alongside a restrictive password policy with no ui explaining what the policy is.

                                                This happens on some HP printers too, the web interface lets you happily enter lengthy passwords, but doesn't bother telling you it truncated the entry at 16 or 12 characters.

                                                    I unfortunately had the infuriating experience dealing with a (government, of course) site that did this. To add to the experience, not only did it silently truncate at registration, but it did NOT truncate on the login fields. And of course, it has a lockout after several failed attempts. UX gore at it's finest.

                                                      Happened to me a few times. And then your password never works and you can’t understand why.

                                                      Probably because that's just unnecessary. A few dozen characters is plenty, anything beyond that is just excessive.

                                                          Unbounded length anything is a denial of service vector, even if they do hash. I can assure you that even if your password manager doesn't impose limits, you can most certainly hit some if you try hard enough. It is also completely pointless. Two dozen or so ASCII letters and numerals will let you encode all the entropy you could possibly want.

                                                          Expiration is self-evident. Long lived tokens you can just whip around will whip around. The number one group of people who are hurt by expiration are those not using a password manager anyways. Autogenerated and autofilled passwords can expire all they want, it's a non-issue.

                                                          Special characters are dumb and unnecessary. They also pose a fun challenge when you happen to run into a situation where you can't input them anymore all of a sudden.

                                                          People cannot participate in cryptographic schemes, only machines can. These gimmicks do not help fix that. It's "theatre", as they say.

                                                            Good security policies should have an upper bound on password length, but also those upper bounds should maybe be like 100 characters or so. There's a couple reasons for this. First being is that hashing does take some compute resources, second being that there is some security/usability tradeoffs here, etc, and third being that after like 30 characters or so, the effective (key phrase here) security gains become marginal.

                                                              Because that opens you up to an entirely new class of attack. You have to set the limit somewhere and if you set it at INT_MAX, then a malicious user could find a O(n^2) path in your password validator and input a 4GB password that locks up the machine. Or they could create 1000 users in a row with 4GB passwords and fill up your storage.

                                                                Due to corporate IT working its fingers into everything vaguely computer related, I now have to annually change the passwords that operators use to log onto the HMIs on my OT network (which has no connection to the greater Internet.)

                                                                That means I now get calls after hours for a couple weeks (allowing for all shifts to cycle through) from operators who are locked out of their ops stations. I can't send the password via email, obviously, and word-of-mouth is inconsistent at best. So I'm left with the sticky note under the keyboard or stuck to the monitor, which the operators won't read anyway.

                                                                • wildzzz · 5 days ago

                                                                  • ornornor · 3 days ago

So what we were doing is that when it was time to rotate password, we would change our password 3 times in a row and on the fourth time we would just use the same password as before. This way our password never changed (the requirements for passwords were ridiculous) and the box could be checked in the audit.

                                                                    Also the same company: we ran a version of our artifact repository that had a 10.0 CVE for almost a year. It was too much work to update it, couldn’t spare the resources.

                                                                  • mikestew · 5 days ago

Oh, because "dozens" of people are tired of changing their password every 90 days, and someone piped up on an email thread (with the subject line: "Changing passwords all the time is bullshit!", I'm sure) and said, "I just set it to $SEASON$YEAR'!'. Easy to remember, fits the policy."

                                                                    And now you have a system that is far less secure than if you just ditched the expiration policy to begin with.

                                                                        So, if your machine does nothing, it's on the guest vlan and has limited access. If it presents a valid certificate that network port is reassigned to the staff vlan and you get full access.

                                                                        If someone leaves, you just revoke the certificate and they have guest access again.

                                                                        Not rocket science once you know it :)

                                                                            Edit: oh wait, you mean have the applications check the certificate? Yes, but then you need support from the application. Does your printer do that, for example? You need to make sure everything does. You can of course do both.

                                                                              That's great when you have control of your applications. For most corporate IT you're stuck with COTS applications and whatever their built-in auth functionality is. Sure, you can probably bolt a reverse proxy in front (if you're lucky enough for it to be a web app and not a thick native code client) but you get to argue with the vendor when they refuse support because you're not using their recommended configuration.

                                                                              802.1x certificate-based authentication at layer 2 is a good defense in depth strategy.

                                                                              • lokar · 5 days ago

                                                                                • lima · 2 days ago

                                                                                  • EvanAnderson · 2 days ago

                                                                                    How is an overlay network "much better" (or meaningfully different) than a device-based certificate and 802.1x when the user is accessing an application delivered over HTTPS using a publicly-verifiable certificate authenticating via SAML w/ MFA (Entra ID)? The source subnet attests successful device authentication in the 802.1x example but that's irrelevant beyond, perhaps, a firewall granting access for the device to terminate a TCP connection to the server's TCP port 443. That's no different than the request coming to the server from an authenticated overlay network, to my eye.

                                                                                    I guess if you want to tie the network layer authentication to the user make it 802.1x with a user certificate. Either way you know the request is coming from authenticated endpoint and the user still authenticates to the application independent of the network layer. In all cases HTTPS protects the traffic from MiTM end-to-end.

                                                                            • lima · 5 days ago

                                                                          • z3ugma · 5 days ago

                                                                            My company sent an internal phishing test last week. Several people immediately reported it to a cybersecurity engineer, posted about it in Slack, saying they were surprised that such a sophisticated phishing attack was happening.

                                                                            I too was surprised - Google is usually much better about catching these kinds of things in the GMail filter before they get through. Oh well, sometimes one slips though. Reported it and moved on

                                                                            Come to learn that the only reason it made it through is because we let it through _on purpose_.

                                                                            By analogy to these red team attacks: _theoretically_ someone could rent a car, pose as an employee, and set up a Raspberry Pi in the network.

                                                                            But who would go to all that trouble?

                                                                            Theoretically, someone could craft a perfect phishing attack, but who would go to all that trouble? Spray-and-pray, low precision, high surface area, attacks are the ones I end up reading about.

                                                                            The only reason this attack vector was open is because the red team stood to gain a massive benefit from succeeding in the attack. What real-world actor would go to the trouble and stand to benefit as much?

                                                                            • lnsru · 5 days ago

Nicha can kidnap some scientists and torture them to get all the secrets. But it’s not elegant. Nicha can pay a lot for hacking and get the result in anonymous way. I guess 8 figures can be paid easily for these secrets. With that money “red team” can launch very nice multifaceted social hacking attack.

                                                                              • Volundr · 5 days ago

The original breach (or at least the breach of this executives account) involved a very targeted phish. When the potential payout is millions it justifies a lot of effort.

                                                                                • lokar · 5 days ago

I'm surprised the pen testers didn't craft such badges. Perhaps it was difficult to get a sufficiently high res image of a real badge from an employee entering or leaving the facility (although, if the front desk is manned, it might be possible to walk up to the desk with an innocuous question and snap a pic of the receptionist's badge if it's visible)?
