How is something like this even possible? It just sounds so incompetent.

HTTPS form submissions should be encrypted while the data travels between the user's computer and the server, but the server will still need to decrypt them to perform the hashing. It's possible, and probably even common, for inexperienced or forgetful developers to add request logging for debugging or diagnosing service outages without adding extra logic to scrub sensitive fields.

>Due to a bug, passwords were written to an internal log before completing the hashing process. Hate to speculate, but it sounds possibly like perhaps a debug statement/log level had been enabled for testing and forgotten about?

Pretty much. Apparently github did something similar and now people are curious about the library/framework. Why is it so obvious that they both used the same library?

We need a regulatory rulebook codified in law by congress that fines companies that make these "mistakes". Enough of a fine will force companies to take these "mistakes" seriously. In Yahoo's case, that might have forced Marissa to actually keep a cybersecurity team and not cut them when she knew the systems were in danger of being compromised. We aren't getting any jail time, but hefty fines that don't stifle growth…

Why? I have a small app with a few thousand users that generate almost no money but contain sensitive data - if I were to be fine because of a leak, I would be dead financially. Where do you draw the line between the companies that should be fine and those which don't? No matter how advance our technology is or the security measures we take, any system connected to internet somehow will have a leak or an intrusion or…

Are you arguing that you should be allowed to be reckless because you cannot afford the cost of being careful?

The "right" way to handle this is to revoke access to all logged-in devices, revoke all previous passwords, send an email notifying users of the revocations, and force a password change upon next login. But Twitter won't do that because a non-trivial percentage of their user base would never jump through the hoops to get things up and running again and Twitter's MAU numbers would sink.

That that is “right” is subjective. Twitter isn’t banking or ATC or healthcare.

I'm curious if anyone has details on using bcrypt/scrypt at scale. Specifically one way I could see this happening is something like login requests go to a load balancer that puts the requests on a queue to be picked up and validated by some hasher service, and the queue ends up writing the requests to logs to recover from certain kinds of failures.

Earlier quoted context omitted.

Superior technologies such as...?

The obvious one is public-private keys. Servers only ever get your public key.

That's a solution I do like. I was expecting to hear biometrics, email login tokens, or social account logins.

Twitter's CTO had an odd tweet about this disclosure (emphasis mine): > We are sharing this information to help people make an informed decision about their account security. We didn’t have to, but believe it’s the right thing to do. https://twitter.com/paraga/status/992135139994943488

He literally could have said just the first sentence and been applauded. Adding the second sentence adds nothing but arrogance.

These comments are everything from eliminating passwords (good luck) to “congress should fix it with law” (lol).

Having been in the identity space for a while and seen how various companies think about it, these kinds of problems will keep coming up...mostly at companies for whom identity is commodity. These companies will always give account security the minimum requisite attention. No one at Twitter gets excited about working on the login form.

I know OpenID was a bust and everyone hates Facebook Connect, but as an industry we need to figure out how platforms that view account security as a necessary evil can vendor that to people who take it seriously. Trying legal avenues to get people to take it seriously or finding alternative methods is what we’ve been trying for the last 15 years and it hasn’t worked.
