Quora Data Breach Exposes 100 Million Users' Personal Info (cbsnews.com)

schwit1 shares a report from CBS News: Information sharing website Quora has announced a data breach which has exposed "approximately 100 million users'" personal data. The company said in a statement released Monday that it discovered the "unauthorized access to one of our systems by a malicious third party," on Friday. Chief Executive Adam D'Angelo wrote in the blog post that Quora had alerted law enforcement authorities and was "working rapidly to investigate the situation further and take the appropriate steps to prevent such incidents in the future." D'Angelo said Quora was working to alert the affected users of the site, whose names, email addresses and encrypted passwords, and public content such as their questions, answers and comments, were exposed through the breach. Those users would be required to reset their passwords, D'Angelo said.

    Even if you're not going to contribute anything, you're forced to create an account to keep browsing. I wonder how many of those 100 million accounts are throwaways used to browse the site. I know mine is!

    Websites shouldn't force read-only users to create accounts. Not only is it annoying, but it wastes resources on your servers and now you have more accounts to potentially get hacked.

      Except that they collect browsing habits/history that are attached to an email address, which is a saleable commodity.

      Probably cuts down on robots indexing their data and selling it or doing whatever with it, too.

      Annoying, I agree, but the evil empire has its reasons.

  2. Encrypted passwords? by viperidaenz · · Score: 1

    I hope not. That implies they're not one-way hashed and if they've stolen the encryption key too, they can obtain the actual password.
    That would be an amature security mistake on Quora's part.

      I'd posit that a mistake that's already exposed that much data, undetected until now, is an amateur security mistake. If they get the data and the key, that's more like infantile.

      It's possible that the term "encrypted" is being used loosely to encompass the process of salting and hashing passwords.

      For users, the problem is that it's hard to know whether any particular site is using good security practices to keep data secure. I use is a password manager (mSecure) that runs locally on my phone, and generate unique random passwords for each site. That way, a breach like this wouldn't allow my data to be compromised on other sites, where I might have reused the password. I don't upload the data from mSecure anywhere, though I keep backups on SD cards. The data and backups are stored with 256-bit Blowfish encryption and a unique passphrase. I know, there's a single point of failure, where all my passwords are stored in one place and protected by a single passphrase, and phones aren't particularly secure. But if I moved the password manager to a laptop or desktop computer, I wouldn't as readily have access to my passwords when I need them. It's relatively convenient, simple to use, and it seems better than many of the alternatives.

      Unfortunately, there's no way for a user to know which sites are secure. It seems like everything should be treated as highly vulnerable, and users should protect themselves accordingly.

    So many data breaches lately, makes me wonder if eventually everyone's data will be worthless. And then what??? Most of the propellant of today's society has to do with gathering personal data.

      I personally *try* to make sure my data is worthless. I mean, they know I like math and science questions, but that's hardly news. I lie about nearly everything personal they ask me; I just make sure my age is over 18. I use a shitty password because I couldn't care less if they crack it and use it to log onto some other shitty site where I have a forum account or something. Personal questions? I tell them that I grew up on Dingleberry street, and my first pet was named "flame retardant banana". (Note: I made those answers up on the spot. See how easy it is?)
