I understand what you are saying, and what you want… but admitting fault publicly is a huge liability, as they have then stated it was their negligence that caused the issue. (bear with me and read this wall of text – or skip to the last paragraph)
I’ve worked in the Sec Ops space, and it’s an arms race all the time. There are tools to help identify issues and breaches quickly, but the attack surface is just not something that can be managed 100%. Even if you know there is a problem, you probably have to send an issue to a developer team to update their dependency and then they might need to change their code as well and get a code review approved and get a window to promote to production. A Zero-Day vulnerability is not something you can anticipate.
You’ve seen the XKCD of the software stack where a tiny peg is propping up the whole thing? The same idea applies to security, but the tiny peg is a supply chain attack where some dependency is either vulnerable, or attacked by malicious actors and through that gain access to your environment.
Maybe your developers leverage WidgetX1Z library for their app, and the WidgetX1Z library just updated with a change-log that looks reasonable, but the new code has a backdoor that allows an attacker to compromise your developers computer. They now have a foothold in your environment even with rigorous controls. I’ve yet to meet a developer who didn’t need, or at least want, full admin rights on their box. You now have an attacker with local admin inside your network. They might trip alarms, but by then the damage might be done and they were able to harvest the dev database of user accounts and send it back home. That dev database was probably a time-delayed copy of prod, so that the developer could be entirely sure there were no negative impacts of their changes.
I’m not saying this is what happened to Plex, but the idea that modern companies even CAN fully control the data they have is crazy. Unless you are doing full code reviews of all third-party libraries and changes or writing everything in-house (which would be insane), with infallible review, you cannot fully protect against a breach. And even then I’m not sure.
The real threat here is what data do companies collect about us? If all they have is a username, password and company-specific data, then the impact of a breach is not that big – you, as a consumer, should not re-use a password. When they collect tons of other information about us such as age, race, location, gender, sex, orientation, habits, preferences, contacts, partners, politics, etc, then those details become available for anyone willing to pay. We should use breach notifications like this to push for stronger data laws that prevent companies from collecting, storing, buying or selling personal data about their customers. It is literally impossible for a company to fully protect that information, so it should not be allowed.
I fully agree: Companies and their leadership should be held accountable when they cut corners and disregard customer data security. The ideal solution would be that a company is required to not store any information beyond what is required to provide the service, a la GDPR, but with a much stricter limit. I would put “marketing” outside that boundary. As a youtube user, you need literally nothing, maybe a username and password to retain history and inferred preferences, but trying to collect info about me should be punished. If your company can’t survive without targeted content, your company should not survive.
In bygone days, your car’s manufacturer didn’t know anything about you and we still bought cars. Not to start a whole new thread, but this ties in to right-to-repair and subscriptions for features as well. I did not buy a license to the car, I bought the fucking car; a license to use the car is called a lease.
