I just hacked this Adress in a second: 12AKRNHpFhDSBDD9rSn74VAzZSL3774PxQ

Private Key is:
5JdeC9P7Pbd1uGdFVEsJ41EkEnADbbHGq6p1BwFxm6txNBsQnsw


Oh, you mean it was a brain-wallet address generated by a simple phrase.

Yes. The simple phrase was 1 Cheesy


I hate brain wallets people always think they're smart and being unique. They aren't.

Has this ever happened before?

Private Key Hacked by brute force

We are working on this now.  We are devising an algorithm that exploits certain weaknesses to get to address keys.  More on this later. 

The scientific answer to your question is 'Yes'.  But it is challenging.

The Master troll at work again, so just ignore him. The next thing he will do is to direct you to his master list of hacked private keys. ^fake^ Just test him and create 100 or 1000 bitcoin addresses and send it to him, so that they can prove that they found 1 single private key out of the lot. You will wait forever, because it cannot be done.

The logical answer to your question is `No` because it is basically impossible.

The day when they break ECDSA or SHA256 or RIPEMD160 algorithms, the whole financial system will collapse, because most of their systems are based on it too. ^smile^

It is a pretty terrifying thought, literally everything could be easily hacked then.

Encryption is based on using prime numbers only and guessing the right combination of the key is like reading 1 billion numbers and words and then typing them exactly in the same order from your memory, that's how hard it is for even super computers of today to brute force a key.

However if quantum chips start to scale in Qbits and be able to for example, a pin code 3 digits and they are 371 now QC can calculate all the possible combinations in one try without actually trying them but imagine if you have 101 digits do you know how long it'll take for a CPU to put out and try all the possible combos? and the QCs that we have today aren't powerful enough to do the job.

forget about 10000+ years think o present days because mode of currency and value exchange keeps changing every 200to 500 years. take example of past. at early we have nothing but exchange took place with rice and wheat, mango and orange but after that came metals, then came metal coins and paper, then paper currency and we have digital currency for which we need internet
but may be in future we will have someother mediumof value exchange.

probably not possible to find the private key of any certain bitcoin address because it consist of 26 alphabets(a-z) + 26 capital alphabets (A-Z) and ten digits(0-9) so combining all the would produce about I order of billion trillions of possible combination and to find the exact private key would few years then even with super fast bandwidth.

Has this ever happened before?

Follow-up questions:
If there becomes 100 trillion wallets in use, do you think finding a wallet with a balance will become common? Is the current private key secure enough to last 10,000+ years?

Is there a way to scale up the security of the generated private keys somehow if needed someday?



If you have a huge volume the just store it on a flask drive or external hard drive that way the hacker will no longer have an access to your bitcoin since it is not connected online. There are many ways on how to store your bitcoins especially for big time holders. If you are just doing your research then you can find many alternatives on how to avoid hacking and some of it are on this forum.

This was already happened before, that many bitcoin wallets in blockchain has been hacked by someone and $100 million worth of bitcoin has been stolen, but, this hacking was not because of using bruteforce. Hacking a bitcoin wallet using its private key and using bruteforce to know this private key is impossible, maybe it is, if someone would develop this bruteforce up to something that can hack any kind of passwords. Private key contains a 64 character compose of numbers and letter, big and small letters, so it is impossible to do this thing.

I remember using bruteforce to hack someone's facebook and it failed, but sometime it works. Note, the facebook password is more weaker than the private key on every bitcoin wallet, that is why for me it is impossible to hack this by just using bruteforce.

The chances of a private key getting hacked are smaller than you getting killed today in a traffic accident on your daily commuting for your job. Actually way higher odds than you die in a traffic accident than your keys getting hacked (or any keys whatsoever).

So yeah, you got better things to worry about.

You will never Brute force it... Breaking a symmetric 256-bit key by brute force requires 2128 times more computational power than a 128-bit

key. 50 supercomputers that could check a billion billion (1018) AES keys per second (if such a device could ever be made) would, in theory,

require about 3×1051 years to exhaust the 256-bit key space. So... stay calm, it will never happen.  Wink

If you have a huge volume the just store it on a flask drive or external hard drive that way the hacker will no longer have an access to your bitcoin since it is not connected online. There are many ways on how to store your bitcoins especially for big time holders. If you are just doing your research then you can find many alternatives on how to avoid hacking and some of it are on this forum.

I don't think this is accurate. If there's anything "in your wallet" then that means the address has already been entered into the blockchain and is now a matter of public record, so if there were a way to hack someone's private key from their public address it would be easy to find. Even if you have an "empty wallet," which is kind of a nebulous term since at that point it's just a generated key, the question the OP was asking is whether or not someone could hack or randomly generate a duplicate key which corresponds to someone else's wallet - the answer is yes, whether the key has ever been used or not. As other people have said, though, the chance is ridiculously small. It would take far more than the $100 billion market cap of all cryptocurrencies to even come close to the computing power necessary to generate, test and transfer out large amounts of bitcoin from other people's randomly-generated wallets. At that point we'd be better off devoting a supercomputer to spend 7 million years coming up with the Answer to Life, the Universe and Everything... though we'd probably come up with 42.

As far as security for keeping your bitcoin personally safe, yeah, keeping your private keys in an encrypted paper wallet that's been generated on a new, freshly-formatted computer with no network connections and then putting the paper wallets in a lead box and storing them in an underground bunker is probably safe enough. The hacks that I've read about weren't instances of people's wallets actually being hacked, but of the private keys being found when their PC's security was compromised.
