321  Economy / Auctions / AUCTION - RARE set of BitBills (20BTC, 10BTC, 5BTC, and 1BTC) on: April 30, 2013, 12:05:04 AM
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I am auctioning off a full set of BitBills: 20BTC, 10BTC, 5BTC, and 1BTC.
These are very rare collector's items. I believe they were the first physical bitcoins ever made. They even came before casascius coins.
The bitbills are intact and have been kept in my safe since I got them almost 2 years ago.
I make no guarantee that if you cut the private keys out, you will be able to redeem the bitcoins.
As far as I know, no one has had any trouble redeeming bitbills.
But if you are bidding on this auction, you likely want to keep these intact as collector's items.

The public addressed for these 4 bitbills are:
http://blockexplorer.com/address/1h6tSi7H1wgCP3ogBKPxESwejaxjBG7Tq
http://blockexplorer.com/address/1MQjzqi4NXnXZZRzADNX7cijKqKekaVSff
http://blockexplorer.com/address/1Lmm1yiDu2VnNQZmZKSvMXCBXez3ZqKkZ7
http://blockexplorer.com/address/14bEcpGrqhr8XbJ1LDaFFT8KADPUrqNb8z

Pictures:

http://i.imgur.com/s6UpxcUh.jpg

The starting price of the auction will be 40 BTC. Please bid in increments of at least 1 BTC.

The auction will end in a week on May 7th 9:00 PM GMT. Each valid bid will delay the end time by another hour.

When the auction is over, I will PM (GPG signed) the winner an address (or post here publicly if that's what the winner prefers) and I expect payment promptly (2 days).
I will offer to the next highest bidder in case of non-payment. The bitbills will be shipped and insured to the winner within 3 business days.
If you want to do the transaction in person (at Bitcoin2013 or something), I just ask for a 10% deposit until we meet and complete the transaction.

322  Economy / Auctions / AUCTION - 25BTC and 5BTC (Series1) Casascius coins on: April 29, 2013, 11:51:54 PM
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I am auctioning off 2 coins: a 5BTC casascius coin and a 25BTC casascius coin. Both of these are Series 1 coins.
So the hologram has the misspelled "casacius" and the public address is printed on the hologram

The starting price of the auction will be 35 BTC. Please bid in increments of at least 0.25 BTC.

The auction will end in a week on May 6th 9:00 PM GMT. Each valid bid will delay the end time by another hour.

When the auction is over, I will PM (GPG signed) the winner an address (or post here publicly if that's what the winner prefers) and I expect payment promptly (2 days).
I will offer to the next highest bidder in case of non-payment. The coins will be shipped and insured to the winner within 3 business days.
If you want to do the transaction in person (at Bitcoin2013 or something), I just ask for a 10% deposit until we meet and complete the transaction.

Mike Caldwell verified that he did indeed sell me a bunch of coins last year: https://bitcointalk.org/index.php?topic=186198.msg1936260#msg1936260

I'm sure that you won't buy best not to handle these without wearing cotton gloves or something similar as once brass gets touched by hand it can tarnish quite badly in time, if you don't have gloves then either don't touch them or if you must then only by holding the edges, please to excuse if this is all obvious anyway already.

Of course! I just took pictures. Uploading right now.
326  Economy / Auctions / Re: AUCTION - 30x 1BTC (Series1) Casascius coin on: April 29, 2013, 07:43:43 PM
I'm going to my safe to get these coins now. I will post some pictures later.

Does any of the ltc devs/coblee plan on updating the lite coin electrum client?

+1

We're focused on updating the qt client first. Once that's done, I will look into updating the electrum client.

Can you clarify which time you will be using for end of auction? Will it be UTC, EST, etc.? Thank you.

The auction ends at the end of April 30th at midnight GMT unless extended by a previous bid.

That's what I meant. Can't edit previous post.

The auction will end on May 1st 12:00 AM (right when April becomes May). Each valid bid will delay the end time by another hour.
Which timeframe ? UTC ?

Any leads on what could have caused this? Or who the thief is?

Will reimbursing affected users be considered?

I am collecting all the information I can, still not clear of the exact root cause. There are a number a blockchain.info wallets compromised in this transaction but i'm not sure it is exclusively blockchain wallets, some of the input addresses look like wallets from other clients (i.e. they use change addresses and transactions are not shown as being relayed by blockchain). More data points are needed.

I am not convinced this has anything to do with Android. I've seen some chatter about brute-forcing attacks against blockchain.info wallets. Is it possible some older wallets have passwords that aren't strong enough? The b.i KDF is SHA1 repeated only a handful of times, iirc, because JavaScript is slow.

I think it is possible to rule out an android problem, several users have stated they do not use an android app.

Brute forcing is a possibility but I remain sceptical about the feasibility of brute forcing 10 character passwords. A 10 character password, 10 rounds of pbkdF2 with 36 possible characters at 5 million guesses per second would take 80,000 days to search the entire key space. I'm not sure it even possible to achieve 5 million guesses per second http://arstechnica.com/security/2012/12/25-gpu-cluster-cracks-every-standard-windows-password-in-6-hours/ estimates rates significantly lower speeds (if  pbkdF2 can be considered close to bcrypt speed). That is for one wallet as well, this seems to be multiple wallets in parallel. All wallets have a unique salt so precomputed dictionary attack shouldn't be possible. Also I have setup several wallets with deliberately weak passwords that are unemptied.

All users affected so far have had JAVA enabled possibly this is the result of some malware spread through a java applet. I can't find the post now but there was a report of a malicious Java applet designed to collect wallet data.

Other possibilities are XSS or a leak of passwords from another site although there is is no direct evidence of this.

piuk, how are you generating keys for wallets? Is it possible it's not random enough and someone has just been able to find the keys by brute forcing the seed to your RNG? bitaddress.org uses mouse movements to add more randomness and it doesn't seem like you do something like that.
332  Economy / Auctions / Re: AUCTION - 30x 1BTC (Series1) Casascius coin on: April 26, 2013, 08:54:34 PM
I also started an auction for a tube of the Series2 casascius coins:

See this other auction thread for my auctioning of 30x Series1 1BTC casascius coins: https://bitcointalk.org/index.php?topic=186198.0
This auction is for a tube (30 coins) of the Series2 1BTC casascius coins. They will come in a square coin tube like this:
http://www.amazon.com/Square-Half-Dollar-Coin-Tubes/dp/B004DB1K2E
Series2 coins do not have the error spelling and has the address showing through the window in the hologram.

I bought these from Mike and put them straight into the coin tube and kept it in my safe.
So the condition of the coins should be mint, but I have not opened the tube so I don't know if the coins have tarnished at all.

The starting price of the auction will be 33 BTC. Please bid in increments of at least 0.25 BTC.

The auction will end in a week on May 3rd 9:00 PM GMT. Each valid bid will delay the end time by another hour.

When the auction is over, I will PM (GPG signed) the winner an address (or post here publicly if that's what the winner prefers) and I expect payment promptly (2 days).
I will offer to the next highest bidder in case of non-payment. The tube of 30 coins will be shipped and insured (free of charge of course) to the winner within 3 business days.
If you want to do the transaction in person (at Bitcoin2013 or something), I just ask for a 10% deposit until we meet and complete the transaction.

If you know me, you know that my reputation is on the line. If you really want escrow, I might consider it, but the buyer would need to pay for all the fees.

hi coblee, what country are you sending from pse & if it's the states would you be prepared to hold the paid for roll until I visit later this year, if I happened to bid & win any of your auctions, thanks.

This will be shipped from California. I can definitely hold it. I will be at the Bitcoin conference if you would like to trade in person. But I would ask for a 10% deposit if that's the case.

340  Economy / Auctions / Re: AUCTION - 30x 1BTC (Series1) Casascius coin on: April 25, 2013, 02:18:17 AM
So I'm trying to see if auctioning them would work well. Not sure if I will regret this as I've seen them go for >$2000 each on ebay:

Do your coins have the misprint?

Someone correct me if I'm wrong.
All series 1 coins have the misprint (casacius) and the firstbits printed on the hologram.
Series 2 coins do not have the misprint and have the firstbits showing through the window in the hologram.

This auction is for one of the series 1 tubes in the top half of the image.
So it will have the misprint.

Depending on how well this auction goes, I might create another auction for a series 2 tube or another series 1 tube.
