Title: MTGox security was flawed
Post by: harmen on June 20, 2011, 11:37:11 AM
MTGox security was flawed: the API instructions where send using cleartext passwords in the URL.

With such security sense it was a matter of time.

Some unusual tips for creating very strong and very easily to remember passwords from grc.com:

It is not about randomness, it is about length and potential complexity.

Cheers!

thanks. there can never be too many posts about password security. so many people are under-educated in the subject.

Over https.

HTTPS Doesn't mean squat.  (http://www.thoughtcrime.org/software/sslstrip/)

That attack will only work if you have control of a network between MTGOX and their customers.

am I the only one who finds the Mt Gox hack, and this site going up/coming down... on top of that the whole process in general, to be suspect?

Mt. Gox looked like an amateur site, for some reason I question why should an auditor get a copy of their database?

So that means the data is encrypted the URL is not.

There's been a big jump in interest in bitcoin in a very short time - it's not surprising that some sites would go up and down as they sort out an appropriate level of hosting.

This attack does not apply as long as you browse completely over HTTPS. So just bookmark the https://www.mtgox.com/ url, use only that bookmark, and you'll be fine.

HTTPS encrypts also the URL and other request details.
I agree, to my understanding HTTPS sends a signal that we are doing a secure connection(with no data besides IP) and then after the key's have been exchanged it will then proceed to send necessary data after a secure connection has been established.
