No thanks, I can find it myself.   

What - the auditor lost his laptop you mean? 

for a small fee, and the promise of not being persecuted, I can send your apache config file.

P.s.: If, as I suspect, that there has been an injection and possibly a root escalation on mt. gox, expect to see this problem happening soon.

To be safe, Mt. gox need a complete rewrite of their code, plus the use of a stronger infrastructure. But they wont do this, because it would cost them Millions to keep the server offline for 1 month.

Yes, security is important.
FYI: Their site was not even hacked.

It appears that someone who performs audits on our system and had read-only access to our database had their computer compromised. This allowed for someone to pull our database. The site was not compromised with a SQL injection as many are reporting, so in effect the site was not hacked.

Dear Bitcoiners,

I'm sorry to hear that some people have had their account stolen, but I was expecting it.

The problem of Mt. Gox is that it grown too fast, without the correct investment in customer safety. The design of the site is not thought for security, and it is evident even from the API. Basic cornerstones like input validation, or safe data exchange are omitted, as if that was a blog and not a sensitive web application. Luckily Mt. Gox makes enough money to pay admins to control the money-flow.


The bigger problem anyhow, is that other exchanges have blatantly copied the design of mt. Gox, along with its flaws, and with a smaller budget. Thus I expect more security breaches. And this is a big problem for the credibility of bitcoins. Thus I invite exchange owners to:


1) Use the right software. IIS is a big no-no Also Linux should frowned upon. Unix is the way to go.

2) Update the software. You cant leave a known root escalation bug for 6 days!!!!

3) Have your code reviewed by a third party.

4) PHP security isnt too difficult, http://phpsec.org/projects/guide/ , still you missed most of the BASIC guidelines.

5) For god sake, you're moving hundred of thousand of dollars. Use a fucking dedicated server for the database. Accessible only by a local IP. If you wonder why I know this, then you should fire your admin.

If you own an exchange and would like to be safer, for a small fee (in the 5 figures) PM me, and I will tell you if your site is flawed, and if it is I can show you how I can have root access on the webserver at least.
