2^256 Deep Space Vagabond

Where will it save keys it finds?

It saves all keys in a plaintext file called "dsv_bkp.txt", in the same folder as the executable.

What is the probability (per check) of finding a valid, activated credit card number and selecting the correct CVV, cardholder's name, and expiration date, assuming the expiration date is not beyond five years into the future?

Maybe just for a US Capital One MasterCard credit card, to keep things simple. Uses MOD 10 algorithm. http://en.wikipedia.org/wiki/Mod_10 The first six digits of these cards are 517805. Digits 7-15 are unknown - the account ID #. Digit 16 is the MOD 10 checksum number.

This means there is a total pool of 99,999,999 accounts. Assume 10,000,000 are activated.

Expiration date is simple. Most (all?) aren't valid for more than 5 years. That gives a 1/60 chance of getting only the expiration date correct per check.

Cardholder's name is more of a clusterfuck. Let's assume only looking at "black" and "white" names (we're looking for a US account, remember) gives you 85% of all total active accounts. Let's assume common names make up 60% of all total active accounts, and that there are 50,000 common name combinations.

CVV is easy, and we'll assume we don't know how Capital One comes up with these numbers, so it's a simple 1/999 chance.

So. We need to successfully correct all of them in one go, and we have one ~1/10 chance (account #), one 1/60 chance (exp. date), one ~1/83333 chance (cardholder name), one 1/999 chance (CVV).

I think the per-check probability of all this comes to .000000000020020100300621424707921073926538% (low confidence, someone smart should check this because I originally posted this post as a question but ended up giving enough data where I thought I could solve it).

Keep in mind, per-check chance of finding funded bitcoin address is ~0.0000000000000000000000000000000000000000034211388289180104270598866779539%.

To make the numbers a little easier to grasp, here is %chance of finding bitcoin address if "DSV-like software can check 5000 addresses (10M of which are funded or will be funded within 6 months) per second, and 100 botnets of 50,000 computers each":
Per century,
0.00000000000000000000053944517054379188413880293137978%
If 100 botnets of 50,000 computers could check only 1,000 addresses per second (5x slower than above stats for bitcoin), the chance of correctly guessing info on an activated credit card is:
Per century,
10.01005015031071235396%

ETA: I left out PIN number. Point still stands.

Although I still have tons of ideas to make Deep Space Vagabond more fun, I just don't feel motivated enough for implementing them and maintaining this project anymore. However, I don't want to see it die, so if anyone would like to take it over, let me know. Note that I will consider the online reputation of any interested parties as I wouldn't like this project to fall in the wrong hands.

Sad to here that
What is the used language? I may be interested in applying

Glad to see that you're interested!

It's mostly written in AHK (are you familiar with it?), as I wanted to experiment a little bit more with that language, and it allowed for real quick GUI prototyping...  Also, as stated in the original post, the actual address generation is delegated to vanitygen (with samr7's permission).

Could you elaborate on what you would plan to do with it?

[jackjack]

AHK? It's been a while I didn't use it
I'd like to: include the address generation inside the code, allow using an own private key or even a file as a starting point, allow chosing the algo privatekey(n) -> privatekey(n+1) (I didn't read all the pages yet, I hope this isn't already done)
Maybe making it python btw, from what I saw it could be possible

No, it currently doesn't have those features implemented.
And yes, I think Python would be a good option as well - actually the very first prototype of Deep Space Vagabond was a quick Python hack done in late 2011.

I say start from scratch

I'm very proficient in AHK; I'd be willing to help.

Thanks, I'll wait for a couple more days in case other potential candidates show up. 

[flatfly]

I've received 2 additional offers by PM. So, 4 users are currently interested in taking over this project.

As I'm still not sure who to transfer this project to, I will simply transfer it to the highest bidder. Starting bid is 0.3 BTC, minimum increment is 0.05 BTC. I would like to close this a week from now at the latest. If there are no bids at all, I will just transfer it to the candidate with highest activity.

[Edit] I reserve the right to turn down offers from proven scammers.

[...]I will just transfer it to the candidate with highest activity.

You couldn't just open-source it?

I don't feel too comfortable doing that. A little concerned about the potential for abuse, even if limited. That's why I'd rather transfer it to a trusted user.

Abuse?

If Bitcoin can't stand up to this program I'd really rather you let her loose now, before I waste further time

Not that kind of abuse... Rather something along the lines of repackaging the app and potentially abusing new gullible users.

They'd do better repackaging Bitcoin-Qt than a screensaver.

That'd be a little trickier to get away with since there's no reason not to download from the official site. You have a modified version of a "address cracker," though, and you could probably get a good number of people. God willing, they're all poor people. Or.... wait, that's worse, isn't it?

The Downloadlink doesnt work anymore.
Could you please reupp the latest Version of you tool ?

I would very appreciate it

Thank you

Best regards

Google Code started disabling binary downloads recently...

[talker2014]

There are a few other possibilities to upload the file 
It would be nice.
