Bitcoin Forum

thanks

Although I kinda doubt you're the owner of this Bitcoin address, do you not remember even approximately how many characters the password had? Any clues, something it might've referred to? Or was it just a random string? Running a code to recover a password is useless and a waste of time if the password was a long string of random characters.

Edit: looks like my doubts were right.

You have posted different "Bitcoin bounties" on many websites, do you really think anyone is going to help you decrypt someone else's wallet? Get a job, you're wasting your own time.. and ours. Earn your bitcoine on your own.

@OP Do you have the list of addresses holding this 500 bitcoins?

How about the wallet file or wallet.dat?

Just in case you don't have the budget, to begin with, Why not try to rent VPS from Amazon or Google cloud they are offering free for 1 year and use the VPS to brute-force your wallet using hashcat.

If you have the encrypted wallet file backup you can recover your password by using the BTCrecovery tool you can find it from this link below.

- https://github.com/gurnec/btcrecover

Then follow the instruction from here https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#btcrecover-tutorial

Sorry we can't use the command you posted above because we don't know if it safe or not(My doubt the script can steal data)

Hi
Thank you for your positive reply.
Yes I do have the wallet.dat file and it is encrypted and protected by a password. Unfortunately, I can’t remember my password. I tried to use hashcat with different dictionaries and masks but still can’t recover it. And my only solution is brute force now.

This is why I raised my reward to 100 bitcoins for anyone who can crack it. You just need to have a large number of GPUs to be able to crack it.
I am familiar with BTCrecovery but I think hashcat is more efficient as it uses the GPUs of your system automatically.

The code that I provided is very safe, basically it is the hash of my wallet password, not the address. Hashcat is an open source tool and does not send information.

Thanks
Alex

I just think it's a bit weird to "raise the reward" since one of your other threads was posted on 27th and the other on 28th. 10BTC is close to $100k, just saying..

it doesn't matter how much you raise this supposed reward, you might as well raise it to a million bitcoin and it still remains impossible to crack something that you know nothing about. because it is like wanting to find a single grain of sand on the planet earth because you don't know which country and which beach the sand was on! even if you had all the GPUs in the word you still wouldn't be able to crack it.

that is how brute force works. you want to find a single grain of sand in all the sand in the world, it is impossible unless you limit your search to a bucket of sand. that means knowing number of characters in the password, type of characters used (letter, upper/lower, symbol, numbers), if the pass was long then at least some part of it,... and someone that actually owned the wallet has some idea what its password was specially if it contained 500 bitcoin in 2016 which was worth approximately $250k!

If your password was generated by a random generator, why would you check dictionaries for your password? Surely you should know at least the composition of your password (is it words, random characters, random numbers?).

Despite your promise, it will not be possible for anyone to enforce your promise to pay 100 btc to anyone who brute forces your password. 

Hi Alex,

First of all, I would recommend you NOT to include the full hash of your wallet as you are not sure whats included. Some hashes include more than just the password.

Second seeing you have posted this on multiple sites, you should avoid exposure and instead contact a few trusted recovery services.

Looking at your hashcat command, there are a few things you should take into account.

8 characters or above using ?a will not solve it in your lifetime
hashcat64 is a hashcat 5.1 command, you should try the beta which is more optimized
-w4 command is not very good either, try w3

Also, before doing a bruteforce attack, you should make a list of password you used in the past and find a pattern. Brute forcing this wallet
with random characters will not do it. You will need to narrow down the search
1) any words used
2) combination of words or numbers
3) narrow down special characters, maybe the most common 3-4

Finally, exposing yourself like this you are basically begging for scammers and hackers to send you harmful code.

Except of the standard dont run any software people send you, dont open PDF or WORD documents, they do most likely include keyloggers and
trojans that will steal your wallet file or even worse, encrypt your drive.

Therefor, dont store your 500BTC wallet on any computer connected to the internet.

Having experience from multiple wallets I would say this version is the most optimized https://hashcat.net/beta/

If this is indeed your wallet after someone will crack or find the password you agree to send wallet.dat to a trusted escrow and Escrow will send 100 bitcoin to the cracker and also will hold their fee for this service?

First of all, this won't ever be cracked. Secondly, if it ever were to be, I'm sure the person who cracked it would just go ahead and take the 100 BTC out of the wallet before sending the password back to OP. If not just go ahead and keep the whole thing since it will probably be worth trillions by the time it's cracked. If you don't know anything about the password and it's several characters long, you may as well forget about it.

There's no proof that this wallet is owned by this guy for all we know, it comes randomly from someone else, and if ever it can be cracked which is not really that easy I don't think the cracker will give him all the Bitcoin, the general rule here is if you don't have the key you don't own the coins that are on that wallet.

There are three possibilities or outcomes of this.

1- You do not own this wallet and want to get free 400 bitcoins if someone do crack it.

2- Even if you own and someone crack it, why would he give you the bitcoins and get 100 bitcoins free. He would run away with your all 500 coins.

3- If this is cracked and it was easy to crack wallets, would you think people would trust bitcoins ? Never, it wouldn't be worth anything if this gets cracked  ;)    

Thanks you everyone for your reply.
However, unfortunately most replies come from people who obviously don’t know what they are talking about (except KeychainX).
The hash that I provided, is a hash of the password only (I.e. you can only recover the password that is used to encrypt the wallet, not the private keys!). If I get the password, I will be able to decrypt it and find the keys...
Also, given the fact that I provided the hash of the password, means that I own it.

KeychainX, you are right, most of the replies that I received so far is from scammer. I really regret posting this, obviously there are no experts here, just amateurs and negative replies I am  afraid.
Cheers
Alex

What did you expected?
How many blockchain 'experts' can you find in the whole world?
Only a few of them.

Bitcointalk is NOT some secret place of hidden blockchain experts and hackers that wait for someone to come.
It is the same as every other service offerings, you need to ask and wait.

Let me get this straight. You want random strangers to help crack the password of a BTC wallet which is close to impossible with current technology and we have no idea whether the wallet belongs to you or someone else. Absolute insanity.

Did you really expect people here to simply shower their blessings and help you get rich all of a sudden? On top of all this, you have the audacity to say that majority of the posters who replied are scammers and amateurs. Ironic that you say this while behaving like a scammer yourself. You are hilarious!

OP, I advise you to use this program
https://www.thegrideon.com/bitcoin-password-recovery.html

The best advice that was in the Russian forum is hypnosis. You may remember your password :)

already touch that program, it used for GPU really big resource, just careful it can made your PC get hang after 3 hours run continuously.

this OP using johntheripper for BTC for extracting password for his wallet i think. last year made an attempt to break my wallet password and it successfull since i only know the pattern. Hope u can remember your portion of the pass and guess it right . ;D ;D

Any solution that for this software to run more than 3 hours without PC get hang?

Very suspicious. In this thread you posted that you have a wallet that contains 500 bitcoins which is not bad amount but in this site that you posted too stated that "Hi Everyone I have a bitcoin wallet that contains 50 bitcoins. Unfortunately, I can’t remember the password as the wallet was created in 2016. I will offer you 10 bitcoines if you can recover my password. You need to run the code below on a large GPU or CPU cluster using Hashcat. If you can find the password, please send it with your bitcoin wallet address to (alexwallet49@gmail.com) to get the reward. About the password, It was generated by a random generator. I don’t know the number of characters.). Even if this is true you still won't be able to crack the random generated password for your wallet. First, your wallet contains 50 bitcoins and you'll give 10 btc to whoever cracked it and then you have 500 bitcoins in your wallet  and you'll reward 100 bitcoins. It's like that your bitcoins stored in wallet and the reward are multiplied by 10.

Good job at finding it, OP increased the reward to 100 from 10 and also the total amount wallet contains from 50 to 500.
Pretty smarty but now he's guilty of two things.
-Attempt to scam
-Plagiarism
I wonder if he cares about the ban.

Here you have 50 bitcoins.

Same here.


https://i.ibb.co/Tr5WX0m/image.png



On this forum you already have 500.
Are you a magician, Learn to propagate bitcoins please.

Thanks all for your reply.
Actually, both of the posts are mine and I did increase the reward as I spent more than a month trying to find the password without any luck.  This is not a scam.
If you think it is a scam, then you definitely don’t understand how to find the password.

Any comment about how to find the password (please don’t ask for the wallet file please or send me a link) will be highly Appreciated
Regards
Alex

Do you remember the site or app you used to generate the password?

If you really have this amount of bitcoin I would go for hypnosis for sure.

You had a lot of good posts here.

any clue is going to be better than nothing
