https://gist.github.com/epixoip/a83d38f412b4737e99bbef804a27... Looking at phpass (one of the md5 algorithms), a high-end GPU can do 7M hashes per sec.

nowhere in these benchmarks anyone said the MD5 were salted. am i reading it wrong?

Unless you're operating under the (likely incorrect) assumption that the salts aren't leaked than salting the password doesn't matter for attacking a single user - it just means you can't reuse your results for other users.

Look up benchmarks for cracking MD5 hashes. You can crack an MD5 hash of an average length password (and StockX only requires an 8 character password), even with a salt , within seconds with a single consumer grade GPU. A hacker group with any serious setup for hash cracking has almost certainly already cracked most, if not all, of these hashes.

Unless you presume that you know the salt your comment is utter nonsense. The fact that the article says “believed to be” strongly suggests that things are not as simple as they’re “believed to be”, because if the passwords were easy to crack that’d be trivial to prove.

If the hash has been leaked then why is there reason to believe the salt _hasn't_ been leaked?

> ...The company “robbed their users of the chance to evaluate their exposure” by not informing customers of the breach when it happened... StockX is valued at $1B and aside from their cataclysmic choice of using MD5 + salt as their way of hashing passwords (They obviously don't take security seriously) the company failed to inform their customers of this security breach as soon as it happened and left it very late f…

Jeez. Even coding bootcamps teach developers to use at least bcrypt for passwords.

I had a similar experience, but I made the mistake of taking the job. I spent several months in denial about how smart people who act so... not smart. At one point, I asked the CTO for guidance on how to work with the team architect whose feelings I kept hurting. For example, I wrote a constructor for a class, and the architect asked me what "def initialize" was for, and got upset when I asked if they knew how OOP in…

I used to work closely with Quicken Loans and other FoCs and can attest that this behavior is commonplace. There is this strange culture within the Family of Companies where non-tech leaders think that tenured Quicken engineers and tech people are these sort of super-geniuses. Many years back I was a part of a company in the Quicken led start-up space. We were often "encouraged" to meet with Quicken or FatHead senior…

What on earth is a ‘family of companies’? Googling for it just gets me some sort of crane conglomerate.

I very nearly worked there in their engineering department, but once I got through the initial HR interview into the technical stuff, there were so many red flags that I got outta there as soon as I could. A few higher level people who were all let go with me ended up going there, and having met up with them a few times, I've heard some absolute horror stories about everything ranging from dev workload, to security,…

Discussions regarding use of MD5 hashing is missing the point, Capital One and Equifax had plain text data exposed. The hashing strategy is irrelevant.

"Discussing one company's bad security is irrelevant because a totally separate company had even worse security"? I don't see where you're coming from at all.

There are two topics that are HUGELY overrepresented in discussions of computer security: password complexity and password hashing.

MD5 hashes is not good. But it also isn't catastrophe level security. If you aren't reusing passwords then the hashing choice doesn't matter since the system has already been breached. If you are reusing passwords you don't exactly want to rely on bcrypt hardness to keep you safe.

If I could make the web services I use switch to MD5 hashes and spend more time on other relevant security posture, I'd very seriously consider that.

Huh, that’s a bit of a random collection of stuff.

I expect a lot of downvotes for this post from people who have not had experience working with people in fashion. Investors should be weary of people from the fashion industry. I say this as someone who has both a computer science degree and a fashion design degree, and 90% of my friends were in the fashion industry at some point. Coming from tech, you'll find people here are much flakier and just unreliable. In the…
