Seems like you guys are in a good track, and have lawyers that can help you... The future is starting to look brighter, good luck Smiley

Awesome indeed, but not sure if they're from the owner... The pictures come from the old Gridseed website and from a chinese forum Grin One of those pictures is from a guy who said he had, if I'm not mistaken, 800 5 chip's...

Even 13,09 euro you're not going to earn back with that thing Wink

Yeah, pretty bad! Good old days when you made a nice buck with a few of these units Smiley
3163  Bitcoin / Bitcoin Discussion / Re: SARUTOBI Returns!! on: April 09, 2015, 02:44:45 PM
Didn't even realised it was gone, never uninstalled it Grin Glad it's back on, it's quite fun. Usual stuff from Apple to remove apps out of the blue, nothing unexpected or strange...

Great news. This is what all other exchanges should follow. Multi-sig is essential and a minimum requisite to run an exchange nowadays, in my opinion...

Very good move Smiley

3166  Economy / Services / Re: I'm BIP38 curious, please help me out! on: April 09, 2015, 11:07:51 AM
Code here -> https://github.com/Dirbaio/bip38-cracker
I've put installation instructions in the readme. Tested with Ubuntu 14.10.

Actually there was this other repo that was linked earlier ( https://github.com/cscott/bip38-cracker ) that is quite faster, probably because it uses scrypt-jane. I fixed it up to read the passwords from stdin so I can either crack from a wordlist or a generated list. Stuff's explained in the README.

It took ~20 hours on three n1-highcpu-16 machines on Google Compute. Each one did ~50 passwords per second, 150 total.
It cost around $38 overall.

So yes, cracking 5-char passwords is definitely feasible for relatively cheap. Would be way cheaper if I had used my own hardware.

The password? The cracker sent me the coins and then I destroyed the instances without writing down the password, silly me. Sorry! Sad


Well... you seem to have a lot horsepower Tongue Quite a bit more than my modest 4 cores.

I'm using this https://github.com/cculianu/brute38 as it's easier to setup the wordlist, allows stopping and resuming and it allows to split the work for several computers. I don't know if the tool you linked is capable of the last two.

Meanwhile, I tested your tool. It has about the same performance as the tool I'm currently using on my devices (about 1 password/second/per core). It would be pretty cool to measure both tools face to face, but the differences in hardware are just too big Smiley

PS: the tool I linked is also outdated. If you need updated files and help setting up, feel free to send me a PM.
3167  Economy / Services / Re: I'm BIP38 curious, please help me out! on: April 09, 2015, 05:12:26 AM
And I added the Fourth one with 5 random characters using only lower case letters from "a" to "z".
That sounds more affordable than the 6-char one Wink
Will give it a try now.

What tool did you use? Any good tutorials around?

I used this one: https://github.com/notespace/bip38-cracker
It's quite broken though, I had to fix it. I'll try to clean it up and post it to my github soon. Here's a quick summary of what has to be fixed:

- picocoin submodule broken -> point it to https://github.com/jgarzik/picocoin
- Fix build scripts
- (This one drove me nuts) EC point conversion is broken, it should convert the passpoint as compressed and the pubkey as uncompressed, it was doing both compressed. I made a quick ugly hack in picocoin to workaround this.


Seems like you have quite a bit of processing power. Congratulations, what was the pass on this one?

Has everyone been paid? Still waiting for my payment. Meanwhile, the bot is counting the posts for this next week already...

Well, didn't know this service, pretty interesting, thanks for posting!

I guess it would be nice to not have your information sold constantly though.

If that is your issue you can join Ello Smiley they do not seem to be monetizing our content, so far.
3171  Other / Meta / Re: 'Recruiting' Participants? on: April 07, 2015, 08:31:41 PM
I don't see how could that be harmful. I wouldn't mind receiving such PM's. I'm fan of simply deleting a PM if I don't like it or don't find it useful. But there are people who aren't definitely going to like it. Not worth doing it, one might have a few reds thrown at him...
3172  Bitcoin / Bitcoin Discussion / Re: Neobase decentralised social network! on: April 07, 2015, 08:00:40 PM
This doesn't really fit Bitcoin discussion Smiley

Anyways, how is this safer than any other social network? How is this serverless? How does it connect between devices, do they all have unique ID in the network? Pretty hard to run such system without main servers Smiley
3173  Bitcoin / Bitcoin Discussion / Re: Fingerprint private key on: April 07, 2015, 07:50:59 PM
I don't see how could this be useful. I only see fingerprints useful to access funds, and we already have that (things like TouchID).

For key generation it would probably be more useful to use things that aren't easily accessible, such as a retina scan. Now that would be nice, either for generation or accessing funds Smiley

Too bad the article is incomplete. This is great news, nevertheless, in my opinion Smiley
3175  Bitcoin / Press / Re: [2015-04-07] Boston Globe: Their data held hostage, Tewksbury police pay... on: April 07, 2015, 06:03:33 PM
Things like these have been happening constantly in the last few months. I don't know what's worse: hackers taking advantage of Bitcoin to do these things or police and justice departments without basic malware protection... That's what happens when you cut corners while building systems with sensitive data. And when you have people accessing things they shouldn't.
3176  Bitcoin / Press / Re: [2015-04-07] ARS - Bitcoin Foundation is “effectively bankrupt” on: April 07, 2015, 06:00:00 PM
One thing is they're bankrupt, the other thing is wasting 4.7 million. How is this even possible? Wasn't outraged with the news, but now I am with the numbers... It definitely isn't possible to keep having a Foundation...

Shame on them. If this is the PR we have for Bitcoin, might as well not have it.
3177  Economy / Services / Re: I'm BIP38 curious, please help me out! on: April 07, 2015, 05:52:45 PM
Trying the second one with all 5-letter english words right now... All lowercase, I hope there's no uppercase letters Smiley

EDIT: Found it! The password was 'grAce'. and DAMMIT someone beat me by ~2 hours Sad

EDIT2: And I'm not even going to try the 3rd one. I can try ~20 passwords per second with my current setup, and I've calculated cracking it will take ~30 years...

Thanks for the fun challenge! Smiley

What tool did you use? Any good tutorials around?
3178  Local / Portugal / Re: Exchanges on: April 07, 2015, 05:44:56 PM
Obrigado pelo feedback. Estava em dúvida entre Bitstamp ou Kraken. Creio que vou optar pelo Bitstamp.
3179  Bitcoin / Bitcoin Discussion / Re: BIP38 and metal bitcoin wallet solutions on: April 06, 2015, 11:06:56 PM
Well, https://bitcoinpaperwallet.com/ can also do what you need. Go to validate or decrypt, put your private key there, click on print and activate BIP protection Smiley

Or simply make a new address and sweep your funds there! Probably safer Smiley
3180  Bitcoin / Bitcoin Discussion / Re: Bitcoin takes the west coast! on: April 06, 2015, 10:59:53 PM
Well, guess you lived the dream Cheesy I wish it was like that around Europe... Not many places accepting Bitcoin, except in Holland and some in France, for example... But it's not an utopia anymore to think that many places will accept BTC soon Smiley
