Wow. Coinbase's userbase is almost exclusively male. Just an interesting observation.

It's possible that is pattern isn't exclusive to coinbase. Perhaps bitcoin users in general are predominately male

Or since there's no evidence that this list is at all representative of Coinbase's userbase, perhaps the "attacker" had a predominately male list of emails.

I got two requests already. What kinda morons works at Coinbase to allow this?

Silent downvotes are cowardly! Yes, they are morons as the issue was reported to them and they refused to address it - it clearly shows that they don't rate-limit the API, which is moronic! Just because Coinbase is a YC company, it doesn't mean we should put up with their crap again and again! Just recently had to get bitcoins and they cheated on the rate again and again! I really don't like that anybody can pollute my history with fake requests like this either! Poor design choice, that what it is! Just like storing transactions in MongoDB, just because it's cool and "first" in the financial industry!

So, users opt-in to providing their names to be used with Coinbase transactions, then are unhappy when said names are used?

Perhaps yesterday's "bug" reporter was unhappy at being dismissed (and he paid for Burp Suite, too!) so perhaps he decided to cause, in his words, "panic".

There's good reasons to dislike Coinbase but this isn't one of them. And of course the "full list" is bigger - the list just contains some previously-known emails and their associated, optional, Coinbase name.

Does anyone know where or if the full list can be found? I have a Coinbase account but I don't see my name on the abbreviated list. I suspect that the person who made this Pastebin just ran a huge list of known leaked emails, or dictionary based emails through the minor information leakage vulnerability discussed yesterday ( https://hackerone.com/reports/5200 ). I would be willing to bet that this brief list is actua…

Fred from Coinbase here. There is no full list, and there is no leak. We're drafting a more formal response now.

Fred, some advice: make your public notice more sympathetic than that post.

Earlier quoted context omitted.

It gives the full name associated with an email address. A more dramatic but analogous situation would be if an attacker were able to attain password info or credit card info associated with an email address. Just because email address is known does not imply that other personal information should be given away.

Does it leak the fact that you have a coinbase account? That seems private as well.

If someone has your email address it is impossible for coinbase or any service to stop that person from checking if you have an account. All they have to do it try registering a new account with your address and see if it lets them (as most services don't allow multiple accounts to use the same email address).

They're now "morons" to allow people to send payment requests? Perhaps you're not quite familiar with their business model.

I am well-familiar as I'm an early adopter (and sufferer), but how about having a button "report spam/scam"? If I "decline", the attacker will get a confirmation I'm logged into my account and my email and account are verified!

There is no full list. The "exploit" doesn't give you email addresses you don't already have. This is why it was not considered a vulnerability.

It does confirm email addresses you can guess though (which are not necessarily email addresses you have, until they're confirmed), along with leaking other information about that user.

Same. It seems like it can't happen until it happens, and then you face the reality that it happened. It sucks, and there's absolutely no protection for consumers from it. There's not even any insurance policy that exchanges can purchase yet, which is pretty much the only hope at this point.

xapo.com is insured by Meridian group. There's also one in the UK that's insured Lloyd's that I'm drawing a blank on. Have you looked into either of them?

But how can outsiders confirm that they are really insured and not just bluffing?
