Disqus Confirms Over 17.5 Million Email Addresses Were Stolen In 2012 Hack of Its Comments Tool (zdnet.com)

Disqus, a company that builds and provides a web-based comment plugin for news websites, said Friday that hackers stole more than 17.5 million email addresses in a data breach in July 2012. "About a third of those accounts contained passwords, salted and hashed using the weak SHA-1 algorithm, which has largely been deprecated in recent years in favor of stronger password scramblers," reports ZDNet. From the report: Some of the exposed user information dates back to 2007. Many of the accounts don't have passwords because they signed up to the commenting tool using a third-party service, like Facebook or Google. The theft was only discovered this week after the database was sent to Troy Hunt, who runs data breach notification service Have I Been Pwned, who then informed Disqus of the breach. The company said in a blog post, posted less than a day after Hunt's private disclosure, that although there was no evidence of unauthorized logins, affected users will be emailed about the breach. Users whose passwords were exposed will have their passwords force-reset. The company warned users who have used their Disqus password on other sites to change the password on those accounts.

      It wouldn't be a big deal, except that people generally have terrible password habits. The main issue here will be people who tend to use the same password in multiple places.

      The risk is if the hashes are cracked (which is doable if someone thinks it's worth the effort). If that's done, then there will be a sizable percentage of people who use the same email address combined with the same password on other sites too. Potentially banking sites, ebay accounts, etc. Thieves know people do this, and look for it.

      Those people are at severe risk and need to know.

    Sigh. If you're going to pick a quote, pick one that states a meaningful fact. SHA-1's flaw is that it allows a pre-image attack, where an attacker can craft a duplicate message that yields the same hash value as a different message, which is very useful for forging signatures on certificates. But that flaw is utterly useless for more efficiently brute force attacking a password that was hashed with SHA-1.

    All the information I gleaned from this quote is that the author doesn't understand what he's talking about, and his writing isn't worth reading. Oh, and that my password on Disqus is still safe.

    The problem with oauth and the like is that they are a bit like keeping all your eggs in one basket. If the auth provider is breached, it is theoretically possible for credentials to be forged. Unlikely, but possible. It's generally better to compartmentalize, so a breach at one place won't make you vulnerable anywhere else.

    On the other hand, people really don't like doing passwords in a secure way. It is, admittedly, a real hassle. If you aren't going to do passwords securely, then you're much better off using an auth provider.

  13. Passwords are special. SHA-1 is much too fast by raymorris · · Score: 3, Interesting

    You are absolutely correct for SHA-1 hashes of random data, of significant length. Passwords, however, are neither random nor long. I'll describe the attack for you and you can try it out yourself. The fact that an ordinary consumer PC can compute SHA-1 password hashes at the rate 10 billion per second is why SHA-1 is no longer appropriate for passwords. Here's how the attack is done:

    Download two large lists of passwords, any "combined list" from your favorite haxor site will do. It doesn't matter what sites the passwords are from. If you run a comparison, you'll find that given two lists of a million passwords, about half of the passwords will be on both lists - with different accounts. That is, there is about a 50/50 chance that your password is in the list because somebody else used the same password. You probably know it's not too hard to find lists totaling many millions of passwords (we don't need fresh ones). If we put together a list of 10 million passwords, most of the Disqus passwords will be on our list, because SOMEBODY used the same password (not necessarily the same person).

    So we take the first, most common password on our list of previously seen passwords and try it against each of the 17 million hashes from Disqus. Because SHA-1 is so fast, our $100 GPU can check all 17 million hashes in one millisecond. In one second, we can try the top thousand most common passwords. In 24 hours, we can test out 10 MILLION passwords that somebody, somewhere, has used before, and thereby crack perhaps 8 million of the Disqus passwords - which gives us the email addresses to match those passwords.

    For passwords, therefore, you need a hash that can't be easily computed at the rate of billions per second with commodity hardware. Bcrypt and scrypt are appropriate choices. To avoid certain problems with particularly long or particularly short passwords, you first take a SHA-2 hash of the password, then scrypt it.*

    * In the general case of random data, hashing a hash doesn't add security. Passwords, however are not the general case.

      And that in no way defends the incorrect assertion of the article's author that associates SHA-1's flaws with this attack, which was the entire point I was trying to make.

      Regarding the security of the password hash database that was stolen, I was assuming a few things: that the attackers are lazy, and while they might try a rainbow table, they won't bother brute-force hashing salted passwords; and that when disqus says they used a salted hash, that they actually used a proper per-user salt algorithm, and not a common-to-all-users salt.

      And yes, any scheme can still be bruted force attacked with a limited list of common passwords. Even PBKDF2() hashed passwords can be brute force attacked with a very limited number of common passwords (perhaps the top 10, like "password", "abc123", etc.) and no doubt more than a few user accounts will fall. This being disqus (not exactly a high security site), I have to wonder how many of their users reused their same passwords on their banking or other high value shopping sites? Account Take Overs that exploit a common password across multiple sites seem to be the most damaging form of attack in use today, so I suppose it's prudent to assume that this database is no exception, and that the attackers aren't as lazy as I had assumed.

      Of course if they used a common-to-all salt, you can bet that Troy Hunt will start building a rainbow table soon (if he hasn't already begun to do so.) And I'd be even more concerned about the security of that password.
