Evernote Security Compromised

starburst writes "Another online company has had its security compromised. Today Evernote posted on their blog that they're issuing a service-wide password reset because of suspicious activity on their network. They say an unknown intruder gained access to usernames, email address, and encrypted passwords. Even though the passwords were hashed and salted, they're doing the password reset as a precautionary measure. Nevertheless, it's a good reminder to keep a close eye on who you keep your data with in the cloud. Nothing is totally secure; it's always a compromise between security and convenience."

If it was something trivial and stupid like an SQL injection attack then they should give up on their business now for being a bunch of incompetent dickheads. If however it was something more sophisticated then fair enough, you can somewhat sympathise with them.

      But either way I think it's dangerous to try and make it acceptable that a company will get hacked by simply saying "Oh it happens to everyone, don't worry, as long as you clean up properly". That's bollocks, and it just gives companies an excuse "Yeah, we know all your credit card details got stolen because we had an open SSH port with root access available and password of 'password' but don't worry, we told you, and reset your password, consider us excused for the fact you will now be a victim of financial fraud!".

Those users could go on using the same password without being exposed to any additional risk. So why force them to change their strong password to something else?

    I am all for them going public with what they found. But sometimes you really need to have enough confidence in your own protection of the passwords to not go and force everybody to change their password.

    If the attackers had access to sniff the plaintext passwords at login, then it is a different story. But if there was only a leak of well protected hashes, then just let people know and let them decide if they want to change their password. It is not like a password reset is risk free either.

      Yes, thank you for saying this. I'm so sick of forced password resets. I can't remember all the passwords I use, and for some sites that I might actually need to remember them for, having to make a new one means I no longer remember the password for that site! It means I'm more likely to choose a weak password which is easier to remember and easier to crack.

      Thus my theory that forced password resets actually decrease security.

      With the passwords being salted and hashed, they are not easy to brute force. This means for any user who has chosen a reasonably strong password in the first place, a leak of the hashed password is not an issue at all. Those users could go on using the same password without being exposed to any additional risk. So why force them to change their strong password to something else?

      My guess would be the salt was either not unique per account, or was part of the compromised data. Either way it would make it (somewhat) easier to brute-force.

      There is only one salt per account, so of course it is unique per account. But that is probably not what you meant. Could it be that the salt is not unique? It could be, but once you are doing any salting in the first place, it is trivial to make it unique. All you have to do is let the salt be a sufficiently long string of random characters, and the probability of collisions will be negligible.

      or was part of the compromised data.

      Salts are stored together with the hash, so leaking one without the other is totally unlikely. But don't worry. Salts are designed such that they don't need to be kept secret.

      No, it is exactly what I meant. How do you know the salt is unique? Did you write the code? It's easier to use the same salt for every account rather than making it unique, since it can be hard-coded and doesn't need to be persisted with the hash.

      See here for a more thorough explanation.

      But don't worry. Salts are designed such that they don't need to be kept secret.

      Of course, but as I said, if you're using the same salt for all your hashes then it becomes less secure.

      I did not say that I know the salt is unique. I said the salt is unique per account, which is a tautology because there is only one salt per account.

      as I said, if you're using the same salt for all your hashes then it becomes less secure.

      Of course. If you are using the same salt for every account, you are not salting at all. You'd be reducing the salted hash down to simply an unsalted but non-standard hash function. That would not require much more computing power to brute force than an unsalted hash.

      But producing a good salt is easy. All you'd need to do was "head -c56 /dev/urandom | base64" or the equivalent in whatever language the system is written in.

      We will keep seeing these stories until we get more secure protocols for password authentication. What we need is a ZK protocol such that the password never leaves the client machine in the first place. And when the password is initially set up, there need to be one salt from the client and one salt from the server such that as long as one of them do it right, the salt will end up unique.

      People are deliberately designing computationally inefficient algorithms for password validation. Imagine if we could turn all of that CPU usage into some public key cryptography being part of a ZK protocol. We'd get something more secure and could possibly even reduce the amount of CPU time a server need to spend on validating a password.

  21. And how do they know no content was accessed? by petsounds · · Score: 1

    So the attackers were able to get what sounds like direct access to the user database, or best case a backup copy, and yet we're expected to believe that the attackers couldn't gain access to the content database? (assuming it's even a different database) Or at least crack some really weak passwords within the two days before this was reported to users?

    In this kind of attack, the baddies are after the content. The user accounts themselves are mostly worthless -- can't really use them for spam or phishing. But there's probably some dummies out there who have put sensitive information in Evernote, and that's what I'd guess the bad guys are after.

    My guess is, Evernote has no frickin idea whether content was stolen or not, but they DO know that if they said that publicly they'd be in hot water.

    A truly local note app is exactly what I want on my phone, for exactly the kind of security reason as this article highlights. I don't want my notes anywhere but in my pocket. That's why they're notes, not shared documents.

    But no. Most note apps out there automatically sync my private notes to some "cloud service" whether I want to or not. So far the best option I've found has been to install an app which wants to sync to a service I don't have an account on. But that's a dumb workaround to a dumber misfeature.

    Mobile and Cloud are two of the worst things that have happened to computer security at the moment. Far too many people are putting far to much data onto public storage with far too little privacy, and most of the time they're not even aware that it's happening. That's a problem, and eventually we're going to find out how much of a problem. But that will be long after the damage is done.

    I have looked into several open source alternate note-taking programs, but none of them worked for me as well as OneNote - some were too clunky, didn't have decent search, didn't do quick page hyperlinks, poor formatting, whatever. (Full disclosure: I used to work for Microsoft, which is where I started using OneNote - it was free for internal use - but I stuck with it after I left because it really is a great product.)
