Topic: Don't buy "wallet.dat" files with lost passwords; EXCHANGE THEM. - page 20. (Read 19245 times)

It's not a problem of sharing wallet.dat hash itself, the problem is to share cracking resources with someone you don't trust.

For the reference: https://github.com/hashcat/hashcat/blob/master/docs/hashcat-brain.md
Just a simple example:
you run an attack on some hash (no matter which type 3 or 0):
1. hashcat -m 11300 -a 0 myholywallet.hash some_dictionary.txt -r very_cool_rules.rule
2. it fails, and you decide to make another attack then another and another
3. you execute again attack #1 because you've already forgot about it
4. hashcat brain checks if it already done it in it's database, and if so - rejects all password candidates.
5. You earn the time of not doing the same work twice (or more)

Well, actually, only the wallet hash is shared. Correct me if I'm wrong but it can't be exploited to recreate a wallet.dat file.
Actually, I didn't configure hashcat brain. For a bruteforce attack, it is not necessary.
I don't believe brute force attacks are the way to process but let see how it goes.
Meanwhile, I'll try to configure a dictionary attack with brain and prince to check if it goes better.

Hey, it's definitely bad idea to share resources with someone you don't trust.
A better idea might be to share dictionaries and open private (known to specific people) hashcat brain server to the internet.
It will reject password candidates based on attack type and it's position. Of course one who attempt to guess a password should not send password hashes to the brain server, but only attack positions (--brain-client-features=2) otherwise network bandwidth and brain server resources will become a bottleneck.
I don't know if there are some kind of vulnerabilities in brain server, and if it's secure to open it to the internet, but it may be a solution to distributing the cracking power.

I'm interested in contributing in such process, so PMs are welcome by the way of making this happen we could learn to work with each other and build a trust.

I was following this topic for a while and decided now to jump in.
I don't know if I am allowed to post link here so I will provide it through private messaging.

I am sitting here on an old wallet.dat with 50 BTC.
After reading all the comments in this thread I decided to set up a solution to share wallet hashes (not the wallet file).
This solution also splits the brute force tasks among a hashcat connected network of computers.

The only knowledge required is to be able to install python (as well as 2 extensions) to run the client.
It downloads by itself the necessary files (hashcat, the hash files and, if necessary the dictionary files) and share online the resources with the others.

For me the wallet is lost, so if peoples are interest to jump in, they only need to contact me and I'll configure them an account to share the resources.

If we are able to find the password, I will share the 50BTC to all involved participants.

I suggest you use more than 11 passwords to crack the password, most of the wallet files in this post were exchanged to me, at least in the past 3 years or more, the low number of passwords should have been tried, no sense.

Hi everyone!

About a week ago I started working on wallet.data files. Even though I got a private key and it was password protected.
I only set 2 TITANV GPUs on the break to test.

The thing works!

What I am sharing now is for skeptics that it is not impossible to do!

At the moment it seems that I am going for a 5 word experiment and the number of possible variations = 7737809375.
It can also be seen that there are only 2 days 11 hours left.
The 1,2,3,4 word option had already been tested and it wasn’t that hard.
If the password is not 5 words, I will continue to look for the 6,7,8,9,10 ... character options.
Since it would be hard enough with 2GPU there I will already be using a 40 X RTX3090 GPU.
I think in about a couple of weeks you will have quite a bit of BTC and the rest of the altcoin.

Great question!
I don't really have an answer.
To be fair we should think about trust only when we'll get to the point of actual transfer BTC out of cracked wallet.
For now, to start cracking i need only wallet hashes which doesn't reveal any private keys.

Let's crack first and then think about trust

Wow!

I congratulate you mikecolins for the speed you get.

If I could get something like that ...


That would be perfect; the problem is trust. How to trust someone you don't know?

A greeting.

Hey guys, what do you think about combining cracking power and making different hashcat attacks together in parallel?

Benchmark of my setup:
~/hashcat -m 11300 -b

All we need to share is a wallet hash in hashcat format.

What I don't understand is, when I check some of those address, it seems there are some activities on it. How can it be, if the persons really lost their password and continue to receive money there ?
Well, maybe worth though to give a try... Where to find the wallet.dat of those address?

It is not necessary to exchange wallets, but to exchange information about the dictionaries with which these wallets have already been verified.

I would really want to know if someone with a mining farm actually tested with hashcat,and if there would be any results post them here.

Yes this is true statement if you talk about Bitcoin in 2020, in 20k price range.  All of the wallets (most of them anyway) are from 2010-sh period when BTC was at $200 , password standards were a bit easier 10 yrs ago as compute power potential was a LOT less than today, so considering all this, I'm really surprised that besides all those fake wallets, non of the real ones were actually cracked.

All wallet passwords are supposed to be long or very complex to build. As far as I know, only one wallet with more than 30 bitcoins was opened.

So, any of these have been actually opened? Ever?

Hello, I hope you can provide more information about the wallet.

This is yet another good deals for the greedy people, why would I want to buy something I don't work for? BTC that costs up to 22k per one today can be earned by buying a wallet.dat? Either real or not I don't care because it's never my own sweat that gave me those BTC, I don't want such money

Thank you for a good job.
Yes, wallets with 150, 99, 78, 70, and 57 BTC are suspicious and moved to a special table with fix price.
I faced various fake files of 150 and 78 like watch-only, and HEX edited too. Files with Password: "12aVP18cd5XsbcGQy8u6eywQ6UuA6Q319s" are fake.

On my site - AllPrivateKeys, original files only. I check, synchronize, and do screenshots before publishing for sale.
Also, I give a replacement or a full refund till two days if something wrong.

With some luck and skills, you may recover lost passwords and would be able to access the coins. The power GPU farm is good but not enough. I know persons who recover lost passwords using a laptop. Don't forget about luck, skills, and hints for passwords mask.

PS: Beware of scams on forums and just registered sites!
Rare files can't cost cheap. Scammers always sell cheap. They need money here and now, then they run to "sell" to others, and drop contacts with you forever. You are not interesting anymore.

Good Luck!
Merry Christmas and Happy New Year 2021

Thank you avfedorov.

I've tagged the first two "Doubtful".

Greetings.

Hi!

I have these files and looks like all three is fake - they contains same transactions in history.
