Need a way to crack bitcoin wallet password

[Destined2bGreat]

So a family member thought it would be a funny "prank" to put a password on my bitcoin wallet.  Now they can't remember.  I was searching the web and found several methods of cracking the wallet password via dictionaries or typos/variants, but I'm looking for a way to crack via bruteforce.  I have little to no scripting abilities, that is why I am posting here.  I am running a dual boot of windows 7 and ubuntu 12.10, so if anyone could link me to a script for such a thing (if it exists), I'd greatly appreciate it.  Thanks.

Also, when looking at this: https://bitcointalk.org/index.php?topic=117022.0  I was wondering just how I would run the script in multiple instances.  Again, I'm quite a novice scripter.

If this was a viable option I feel as if a lot of people would be unfairly losing their bitcoins

Do you have any backups of the wallet? If they never sent anything after encrypting the wallet, the backup should still work.

[Destined2bGreat]

I never made any backups, unfortunately..  To the above person saying "that's what you get", I obviously didn't play a prank on myself -.- this is clearly doable, simply not by me.  But thank you for your pseudo-concern (in other words, thanks for nothing).  The reason I was asking for a bruteforce method, specifically a GPU intensive one, is that I have access to enough GPU, or I'm okay waiting a month.  It's not really a viable solution, but it's the only one that will work 100%

Whoa, take it easy. What I posted above is really all there is you can do. How many btc did you have?

The post was directed at the other person "gweedo", I appreciated your post, thank you. I had about 5 at the time, which is a fair amount of money but nothing to buy a super computer for cracking over.

Was this on Windows 7? Try right-clicking the wallet file and selecting "Previous Versions". Otherwise, try this:

If you know nothing about the password, even a dictionary attack might not be enough - unless the password is weak, which might be the case since it was supposed to be a "prank".

Honestly, if this "prankster" has a minimum of honesty, you should push him/her every fucking day to pay you back. This is theft/vandalism, not a prank.
Once s/he pays you, you give him/her the encrypted file, and it's up to the person to decrypt it, not you.

That assuming the prankster has a minimum decency, of course.

now thats a funny prank . . .

Don't blame me for your stupidity.

I'm not responsible for the ignorance of others.  That includes you.  Nice to know this is a community with inhabitants that have over 4000 posts of pure unintelligent spam.  Do go waste your life elsewhere, as I'm sure you have other threads to post unintelligent, incorrect responses to  (Tells someone they are stupid after claiming that you can't bruteforce a wallet.  Makes sense).

I've made sure they were aware that it wasn't funny.  Unfortunately, even if they would pay it back, they aren't able to.

Bitcoin is installed on ubuntu, I will look at that thread though, thanks.

Unless he's lying, he was the victim of vandalism. Stop blaming the victim, this is disgusting.

Thank you, I'm glad this community does have a majority of normal members.

Currently downloading a wordlist, then switching to ubuntu to see if I can try and recover via maged's method.

I've made sure they were aware that it wasn't funny.  Unfortunately, even if they would pay it back, they aren't able to.

It's not just "not funny". That's the equivalent of breaking into pieces a $500 TV or something.
But anyway, I don't know how close the person is to you (your child, perhaps?) so I'll no longer say anything. It's your life.

My advice: try to make the prankster remember the most he can about the password. Length, some characters, what words were in it etc. With enough information you can try to break it.

hello,

just wondering how this worked out? have sort of the same problem.

kind regards

You have money on your computer and you let your family used it, then YOUR STUPID! This what you got, you learned a lesson, and now your calling me unintelligent LMAO at least I have access to my bitcoins Also just to rub it in your face, I get paid by going on this forum, so yeah not wasting my life.

Don't blame me for your stupidity.

Vandalism LMAO, no he a victim of his stupidity, he should have had it encrypted it before this, and he learned a lesson Thank you, my ignore button is to the side please press it now.

Makes a post to call another person stupid, doesn't spell "you're correctly", never mind 50% of their words.  You seem to be quite the intellectual.  I was unaware you had your laptop sewn to your chest, carrying it wherever you went to make sure nobody else has 30 seconds to touch it.  You clearly don't have any family members that you care about/care for you, or you would realize that not everyone has their laptop in a dungeon in their mother's basement.  You don't get "paid" to spam.  You most likely get paid for your mediocre, high school leveled coding abilities.  Nobody is paying you to post on this thread.  You're posting here because you have nothing better to do, and are thinking "Hmm, I'm most likely 17 and this will help me feel better about my incredibly low self-esteem!".  By all means, do continue to post and demonstrate to everyone else just how much of a loser you are though, as it does not do me any harm.  I'm sure loads of people will be more likely to contact you for work due to these posts.

I'm currently working on that, but it seems bruteforcing will be my only option.

What a disgusting jerk...

Leaving your car open with the keys on the contact are no justification for theft. Walking with short skirts on a shady neighborhood is no justification for rape. Reacting to an armed robbery is no justification for murder. And leaving your wallet unencrypted is no justification for destroying it.

The person in the wrong is always the one that commits the crime. The one that did not see it coming (even if according to your rushed judgment, "was so obvious")  is the victim.

I'm currently working on that, but it seems bruteforcing will be my only option.

Pure brute-forcing only works against very weak passwords. You should attempt at least a dictionary attack first. There's no much point in trying totally random strings.

Then he should call the police and have them arrested, if it is over $5,000 value it is felony and can do time. Instead of putting it on a forum. But no crime was committed. It was stupidity.

Yes because I'm going to call the police on a younger family member.  You just have all the answers!  Too bad none of them are intelligent or make any sense.  When your paper wallet/phone/whatever gets stolen, I do hope the police tell you it was due to your stupidity  Though you'd have to actually leave your basement for such a thing to happen.  Might be a stereotypical thing to say, but when you accumulate over 4k posts in a year of absolutely nothing productive, it's the truth.

Shouldn't you be paying BTC to watch girls online or something?

If anyone actually has any idea what they're talking about, do feel free to join the conversation!  I'm still unsure as to how one would run multiple instances when using a wordlist, seeing as the words would most likely overlap.  I have the GPU required, this just isn't as simple as inputting the hash into hashcat.

It is my bitcoins if I want to watch girls online I can LMAO I don't see how this is a problem or anything? It is actually a pretty ingenius site, that WW created uses P2P stream the video.

I would call the police on a younger family member, that would tech them a lesson. Considering my paper wallet is valued at high 6 figures, yes I would call the police and press charges if it got stolen cause it be a felony and that person would go to jail. And just to debunk this "basement thing" I actually brought an apartment that over looks the hudson river on the NJ side. I can see the city at night and it did cost me a pretty penny but it was worth it.

Also in over a year of being in bitcoin, I have helped launch some of the biggest sites, I have created and licensed technology to help manage multiple bitcoind's to act as a single bitcoind. I have create many sites. I have also raise my net worth to over a $1 million dollars. This last year was a pretty productive, I would say. And I have graduated from a top school in the USA. So anymore jabs at me? or you content with your shitty life with your brother/sister breaking your wallet which probably had $20, I could lost that all day LMAO.

That's quite a claim coming from someone who pays for porn and just misspelled/used improperly 80% of the words in their statement, and who made over 4000 posts of stupid in a little more than a year.  Good thing you're so wise and informed, that must be how you know that children are sent to jail.  Anything else you'd like to tell a forum of people who couldn't care less

What does paying for porn have to do with anything? and you didn't read all my post, maybe you can actually learn something. See you think these people don't care, but I have an email inbox that shows a different story but that is ok.

Yes forum people that don't care, don't be a stupid newbie and let your stupid siblings or kid play with your bitcoin-qt wallet. It is real money and it should be kept as such. No one has every been locked out a paper wallet.

Fat slimy greeseballs (people who call themselves "guidos" and live in new jersey) pay for porn cams, that's the relevance.  But do keep on talking.  I could tell you that I'm batman all day long.  At the end of the day, nobody is going to believe anyone, and I'm not batman and you're still an extremely unintelligent e-thug on a forum.  Because I know lots of successful college graduates with terrible wu-tang songs in their signature, who can't spell a sentence to save their life, and post over 4000 times on a forum in a year.  That's what all of the wealthy and intelligent people I know do.  Said nobody.  Ever.
