Successful attack was successful. Difficulty just went down when it was supposed to rise.
[/quote]This was really nifty how they did this.
It took less than than the target time to get to the next difficulty adjust so the difficulty should have gone up. Because the attacker overwrote the starting block with one from a day before it looked to the network like it took an extra day. This made the difficulty go down.
This is the first time that I have ever seen this sort of attack. We currently have an unexpected easy batch of coins to mine. Perhaps this is the attackers way of compensating miners for the orphaned blocks :)

[/quote]I tried to say it yesterday (it was not received well) but you said it far better than I.

Haha well, the attacker(s) helped get us a lot of attention, now we must capitalize on that attention. Plus, they have not achieved their goal, Feathercoin is still alive and kicking.

We really should capitalize on that! Not many coins survived such attacks.
“51% attack” sounds pretty cool for some media noobs. Maybe they can write a story about that - and mention “Feathercoin” a few times.

There is a Coindesk article on the attacks today. I spoke to Danny the interviewer earlier today.

[/quote]The difficulty was NOT SUPPOSED to rise. That prediction was based on 60 blocks. 47 was based on 504 blocks.

Can we get the IP address of the attacker that submitted the fake blocks please?I don’t know how to extract it from the chain.
It would also be nice to know which hosts first accepted the bogus chain.
[/quote]You can’t. Thats the whole point with Cryptocurrency.

Nonsense, the BTC block chain explorer has IP and Whois information for every transaction, is just that the feature has been omitted from the FTC explorer.
[/quote]It can be implemented, but I doubt it’s going to help us. Block orphaning isn’t illegal. I know the attackers took their hash rate from the Litecoin network. It can be narrowed down to particular pools and maybe even particular top miners. We cannot terrorise them, they cannot destroy us, so let’s live with it. More we succeed, more they suffer.

$10K a day vs $5K a day will make people do crazy things.

[/quote]I had to laugh at someone in the trollbox last night saying that with the 51% attack, there’s only 49% of the coins left to mine.
Oo
As we come through this, it should prove to people that you may knock it, but it’s not going down that fast. So many people waving their arms and yelling that it’s all over… they’ll be hushed up when the air clears.

I see. Well that service combined with the crypto currency concept makes it impossible to find them.Our focus will need to be on IPS for now.
[/quote]“impossible” is a strong word …

The only way you will catch them is if someone who is involved, was involved or was part of a group decides to brag about it , then maybe you will figure it out. Someone able to pull this off may have a huge farm(s) in a data center(s) somewhere on a anonymous proxy.
With a lot of GPU farms becoming open from asics being released I would say expect some people to have some free hash time to expend.

I’ve been talking to Bushstar throughout the day on possible solutions. I look forward to touching base with him later tomorrow. Mitigating these attacks is priority 1, everything else is basically on hold.

I don’t know if this will help, but this was posted on BTC-e Trollbox earlier today. This is a screencap of messages to him from IsmailTM. Don’t know if it’s legit at all, but who knows, might be something.http://tinypic.com/view.php?pic=35m2vr8&s=5

[/quote]I saw another screenshot of a conversation with IsmailTM. In that one he said he was running the attacks on FTC and ultimately they would take down Litecoin and Bitcoin. He said he could do this because he is building and has arrays of Fusion ASICs running at 200KH a chip and that the budget for this project is $3.2 billion. Eventually they are going to send the send the Bitcoin difficulty up by a factor of ten.
The most likely explanation is that this is complete rubbish :)

[/quote]Indeed. Scrypt ASICs at 200KH/s per chip, 3.2 milliard USD budget… Who is going to provide them with such a huge investment? What’s the profit if they succeed in taking down all major cryptos?

IPtables wont stop a DDoS on this or any other site.
All you need is a few botnets mashing the page refresh and the DB server will crap itself. Or have the same botnets send extended pings and the wan links will flood etc.
True DDoS protection (if there is such a thing) costs 100s to 1000s per month.
