0.4 BTC stolen by hacker - please return them
February 07, 2014, 10:51:36 PM
#1
At approximately 11:30am - 12:00pm GMT today, a hacker was able to exploit a security hole in my game and withdraw 0.4 BTC, which was the entire hot-wallet contents.
He withdrew to this address: 16pknxjJF8yhL2iBPmXRw4rcoGhFYmGcoy
Transactions:
288734e41ebde40bfb07227006f27ea256e3a51e90b7388b4335d9c84f3f90e6

He used the aliases: 1gld,16p,x,y
His attack was to use negative numbers for the BTC fields when creating a new game in blockchain-reaction, although these were checked for client-side, the server failed to do the correct validation.
I feel pretty stupid since that's an obvious attack and I'm usually really careful with this stuff, but it just slipped under the radar. Obviously this is now fixed.
I have covered this loss from my own personal bitcoin wallet, so no users will be affected.
If you are the attacker and you are reading this, please consider returning these stolen coins, I have a suspicion you are a fellow developer / programmer, so please have a heart.
Cheers, Paul.

The hacker won't return the coins. Consider it a $300 education. Had the site been popular it might have been a $300,000 loss.
Saying you are really careful and yet failed to do server side validation is an oxymoron.
I would recommend learning some unit testing. My guess is you are developing the "core" program and consdering error checking as an add on. For larger and more complex projects this always fails. Grab a couple books on Test driven Development (
http://en.wikipedia.org/wiki/Test-driven_development
). The $300 loss could be worth thousands if it makes you a better developer.

This post made me lol.
First of all, what makes you think this "hacker" reads bitcointalk? And secondly, what makes you think that asking him to return the BTC will do anything?
All we have to decide is what to do with the time that is given us.

The hacker did you a favor. You could have lost much more. Consider it a payment for services.

This is exactly my opinion as well. My "lesson" was a lot more expensive and we lost a lot more, but in the end it was a much needed wake-up call. Its best that a breach happens sooner rather than later. Fix the broken pieces and become stronger -- that's all you can do.
Did you know?: Most of our hash power comes from other sources. We are now specialized in the resale of cloudmining contracts through our associates!

Well sometimes hackers or thieves have given money back. I guess trying to guilt someone into returning funds is a last desperate attempt as it's probably one of the only things you can actually do, although like you said it's almost futile. 0.4 isn't much, so I'd just chalk it up as a loss and a lesson learned.

We're back up and running now
Thanks for the support - the general sentiment is right, it could have been a lot worse and the fault is entirely mine for missing that piece of server-side validation. It's particularly galling because I'm a proponent of letting the server do the validation and having none on the client, especially in the early stages of development because it forces you to fix these type of problems before they happen.
Cheers, Paul.
