From Exploit Attack Detection till to the fix in less than 3 hours. That is really good.

I bet you just made the Attacker upset. He/she/it sure has hoped to gather more coins. Smiley

Well, I'm still getting more coins. All network should be updated, it isn't enough to just commit a fix.
Money is not my motivation anyway. Probably will donate this to some open source project.

Just now:

<evan82>  I found out what's going on, I'll have an update out in a few minutes

Edit:

<evan82>  props to whoever figured this out, pretty cool hack
<evan82>  I could use some help programming whoever you are Smiley
Not interested. I'm not so good at C++, really.
Btw, you should hire some real penetration tester, not me or what was the name of that guy?

Ok, could the person who found the bug post here, I promise no one's gonna hate on you. Would be interesting to hear how long it took to find it, and how did you approach it? And also, would you help testing DRK in the future? Smiley

About 6 hours to look through the code to get the main idea of darksend, 2 more hours (got lucky) to find this vulnerability and about 8 hours to code and deploy the exploit.
I will definitely run some more tests with darksend. Will I help or just going to abuse it? Dunno lol. It seems to be more vulnerabilities in darkcoin. Code looks terrible (nothing personal  Smiley)
