My fellow crypto hackers. I've been into finding BTC private keys for a little more than a year. I have slightly less than 18k private keys in my own database.

As some sort of proof, here are 50 privkeys - try importing them in for example Electrum

...and you will get something like (sorry, seems like I don't have the required rank to embed images):

The vast majority of the privkeys I've discovered are NOT from brainwallets (i.e. weak SHA256 hashes). Image search for QR-codes was nice for a while though, but those days are over. I have a couple of other techniques that I'm fairly sure anyone else hasn't thought of.

Every privkey in my database corresponds to a BTC address with at least two transactions on the blockchain. I throw away all "empty" privkeys.

I have a large Bitcoin Core wallet containing all my discovered privkeys. Five smaller transactions happened within the past week.

Anyways.... I was thinking maybe someone here has the same hobby as I do? Care to hook up and share some thoughts and strategies?

Ah, we need to connect. Been doing this for a while too. Our database is bigger than yours. Also only with active privkey/address pairs.

Here are 50 privkeys from our database as proof:

We didn't include the juiciest ones here, but there are a couple of tx from the end of last year.

And we - on the other hand - are able to insert images  Wink Using the privkeys our list above gives:



We agree that Electrum is the wallet of choice for these matters.

Sooo...... where do we go from here?

First of all, there has to be more people here who are into this kinds of research. Make some noise! Or silently join us Smiley

Good stuff: BTCLeak <<< my blockchain hacker friends

As a company, we obviously hit all aspects of BTC, and we have had a great amount of success with collision.  We run these for our investors and we have a strong set of rules about importing the funds, but we have seen more than 1000 BTC in wallets that we found using private key harvesting, so it is a viable method, although morality is a nice sidebar for the use of these techniques.

I found privkey hunting vulnerability when analyzed Bitcoin source code at 2010. I found new ways for vulnerabilities & bug hunting when research my own practical PoW that defends from brutforce & AI attacks. I joined to RSA-576 Factory Challange when nobody knows about crypto future.

That's interesting. What are the sources of your private keys ? How do you come across them ? What do you do if you find a key with addresses with some notable amount of bitcoins ?

I know you wouldn't share but makes me a little insecure if you have established 'ways' to discover private keys online.

Anyways.... I was thinking maybe someone here has the same hobby as I do? Care to hook up and share some thoughts and strategies?
Me too.I'm a rookie though.Started collecting private keys just 2 minutes back.

Me too.I'm a rookie though.Started collecting private keys just 2 minutes back.

It's difficult to talk in general terms about my sources of private keys. I'm not sniffing networks or breaking into other peoples' machines. Nothing illegal. It's more math than  networks, if that makes any sense. And I did mention one of my early methods in the first post - searching for images of QR-codes. In 2014, people would post pictures of their paper wallets on Instagram. Don't do that.

I have so far never had access to a private key with a life-changing balance on it. The vast majority have a zero balance (but all have been active on the blockchain and MAY therefore be used again), and say 1-2% have some dust in them. I've never moved funds from any of them. But honestly, if I stumble over a privkey gives me access to say 50 BTC or more, I don't know what I'm gonna do. They say whoever has the privkey owns the coins.... quite a moral dilemma.

I once found a privkey that had held close to 530 BTC only a month earlier. In one way I'm glad the funds had been transferred before I came in. In one way not.

Hoping to connect with others like me. I'm sure you're out there. I'm not entirely sure what we're gonna do Smiley

BE CAREFUL! If you accidentally use that wallet later on, someone else can access your funds!

How did you find that key? Of course, anybody can just post private keys, and I've done that in the past (see here to add a few to your collection). If they're used and you don't care anymore, it's not that special to share it.

Yes - BE CAREFUL - never use privkeys found online!

Such as these 100 privkeys I just generated with vanitygen

Nice thread, I'm a treasure hunter myself Smiley And yes, like everyone here i know is 100x time more possible i end up fucking scarlett johansson than actually finding anything by bruteforcing.

I have however, found some keys with balance using unconventional methods. Thats the key (no pun) to find private keys. Methods come and go (Bruteforced brainwallets for example). Lots of other methods are dead and so will be a lot more in the future, just a matter of innovating!

Right now i thought, for fun, to develop a script to do old school bruteforcing, shooting in the dark without any specific order, just to see what pops up.

I began by running directory.io clone on a vps, modifying it a bit to display keys so a python script can pick them up and compare it with around 2m known addresses with funds. This beta version is doing around 6000 kps (keys per second) so its quite trashy at the moment, as it does around 500m keys per day

Currently modifying it to:
use 100% cpu, its using barely 30% atm. Multiprocessing, etc.
Convert the golang script to python so it can generate/check on the fly instead of retrieving an html page with the keys
Once this is done, modify the script to become a sort of botnet/pool that can check and upload to a server once it opens in a computer.

The funniest thing is that even that way, i wont find anything Grin!!!

I found privkey hunting vulnerability when analyzed Bitcoin source code at 2010. I found new ways for vulnerabilities & bug hunting when research my own practical PoW that defends from brutforce & AI attacks. I joined to RSA-576 Factory Challange when nobody knows about crypto future.


How to learn this brute forcing method?

Forgot to mention one of my earliest methods. Worked until 2013 or so. Google:

Code:
site:dropbox.com "wallet.dat"

Found more than 10 wallets with a positive balance without any password protection. Not entirely sure how or why you come up with the idea to put your wallet.dat in your public Dropbox folder. Those were the days...

I then guess you are aware of the Large Bitcoin collider. At the time of writing, running at 673.11 Mkeys/s. They've found a few collisions. The odds are not in your favor, diplomatically.

Pure bruteforcing is a dead end.

Think of ways that significantly reduce entropy is my tip. There are a number of ways. People have posted a few, and I have come up with one or two methods myself. Overall however, mining is still much more profitable than going after dust* bruteforce-stylee.

* Yeah, MOST addresses with a positive balance on the blockchain contain dust, hardly worth the effort.

Did any of you try to access wallets by guessing the seed? I think it might be easier to create a program that randomly checks various seed combinations than trying to find a private key with a positive balance. As time goes by there will be so many seed combinations that a modified password guesser linked to a dictionary might do the job. And this time if you'll able to find something it might not be a single address but a bunch of them. You might even get lucky and get into a wallet owned by a treasure hunter like yourself Wink

Electrum has a dictionary size of 1626 words and uses 12 of them randomly, producing 1626^12 possible combinations, which is close to 10^38 combinations. Good luck finding a collision. It will take quite a while. Example:

If somehow could test 1 billion combinations per second (arbitrary number I just came up with), we need 10^(38-9) = 10^29 seconds to try them all. That is approximately 3.17*10^27 years.

The universe has existed for about 13.8*10^9 years.

You see where this is going... right?

No, they haven't found a collision, and they never will find one.
To prove a collision,k you need to show two different private keys that create the same address.

Why are people still doing this, if the probability of finding a private key that is used, is almost zero? Just look at the numbers involved with this in the following thread : https://bitcointalk.org/index.php?topic=104461.0

There are exactly 2^160 possible addresses and 2^96 private keys and there are only 2^63 grains of sand on all of the beaches of the Earth.

The odds in definitely not in your favour.  Wink

-snip-
Yup, by brute-forcing the key, the chance to hit a collision is close to 0.0000000000000000000000000000001%. Wait,

No, what they talking about (in this thread) are those neglectfully stored wallet.dat files, private key backups, paper wallet images or other forms of backups which potentially have funds.
History can tell that some people are stupid enough to store those (not only wallets but passwords and sensitive info too) directly in the internet without "hiding" the files with a disguised file name, file type, etc.

This one for example:
Found more than 10 wallets with a positive balance without any password protection. Not entirely sure how or why you come up with the idea to put your wallet.dat in your public Dropbox folder. Those were the days...

@OP, this isn't "hacking" and... use this to display the image (the link must be the image's direct link that ends with ".png/.gif/.jpg"):

The universe has existed for about 13.8*10^9 years.

You see where this is going... right?

Of course, but it's the same when you're trying to bruteforce a private key. The combinations are endless, but that's not what this is all about. Nobody is trying to test all possible combinations, but find a couple that are in use and give access to active wallets. There's a quite high possibility that if you'll start picking 12 random words out of those 1626 and start messing with them in different combinations you will get a single hit. Isn't that what those "treasure hunters" are hoping for?
Why did I ask about the seeds? Because finding a single one can lead to unlocking a wallet with multiple private keys instead of a single one which the collision dudes are trying to find.

No, what they talking about (in this thread) are those neglectfully stored wallet.dat files, private key backups, paper wallet images or other forms of backups which potentially have funds.
History can tell that some people are stupid enough to store those (not only wallets but passwords and sensitive info too) directly in the internet without "hiding" the files with a disguised file name, file type, etc.

Just recently there was a case of a guy being robbed of his coins because he was storing his passwords in a gmail account and had a backup email connected with it. The backup got hacked and through it they managed to gain the password to his main account.

I managed to scale it to 1Mk/s with some tweaks on a few spare vps's I have, they aren't doing anything so is not like im investing on it or anything, it was a fun project to make though. I'm aware of the LBC, i ran it for a few minutes but preferred to make my stuff instead ;P

But of course, its better to find human-fault keys. I have had luck with ETH keys too Smiley

My fellow crypto hackers. I've been into finding BTC private keys for a little more than a year. I have slightly less than 18k private keys in my own database.

As some sort of proof, here are 50 privkeys - try importing them in for example Electrum

The vast majority of the privkeys I've discovered are NOT from brainwallets (i.e. weak SHA256 hashes). Image search for QR-codes was nice for a while though, but those days are over. I have a couple of other techniques that I'm fairly sure anyone else hasn't thought of.

Every privkey in my database corresponds to a BTC address with at least two transactions on the blockchain. I throw away all "empty" privkeys.

I have a large Bitcoin Core wallet containing all my discovered privkeys. Five smaller transactions happened within the past week.

Anyways.... I was thinking maybe someone here has the same hobby as I do? Care to hook up and share some thoughts and strategies?

Why are people still doing this, if the probability of finding a private key that is used, is almost zero?
-snip-
Yup, by brute-forcing the key, the chance to hit a collision is close to 0.0000000000000000000000000000001%. Wait,

No, what they talking about (in this thread) are those neglectfully stored wallet.dat files, private key backups, paper wallet images or other forms of backups which potentially have funds.
History can tell that some people are stupid enough to store those (not only wallets but passwords and sensitive info too) directly in the internet without "hiding" the files with a disguised file name, file type, etc.

This one for example:
Found more than 10 wallets with a positive balance without any password protection. Not entirely sure how or why you come up with the idea to put your wallet.dat in your public Dropbox folder. Those were the days...

@OP, this isn't "hacking" and... use this to display the image (the link must be the image's direct link that ends with ".png/.gif/.jpg"):
Code:
[img alt=img height=420]https://i.imgur.com/PrBSxN8.png[/img]
Winning a big lottery also has a small chance, you will never know unless you try. The numbers do not work always like that, technically you have two options you can find one with balance or not. Why there are doing this? Because they can.

Did any of you try to access wallets by guessing the seed? I think it might be easier to create a program that randomly checks various seed combinations than trying to find a private key with a positive balance. As time goes by there will be so many seed combinations that a modified password guesser linked to a dictionary might do the job. And this time if you'll able to find something it might not be a single address but a bunch of them. You might even get lucky and get into a wallet owned by a treasure hunter like yourself Wink

Electrum has a dictionary size of 1626 words and uses 12 of them randomly, producing 1626^12 possible combinations, which is close to 10^38 combinations. Good luck finding a collision. It will take quite a while. Example:

If somehow could test 1 billion combinations per second (arbitrary number I just came up with), we need 10^(38-9) = 10^29 seconds to try them all. That is approximately 3.17*10^27 years.

The universe has existed for about 13.8*10^9 years.

You see where this is going... right?

I think that the last few words are a checksum, so your chances are slightly better than that (but still impossibly low).

I'm having an existential crisis right now. Maybe it's because I have a poor understanding of math, but the chances of winning the Powerball lottery are something like 1 in 300 million and it happens all of the time. Statistical improbability does not equal impossibility, in fact it's tangibly the opposite. I could type random keys on my keyboard and potentially end up with an old Satoshi address at my disposal. The chances that someone pops a Private Key increases each time more people are attempting to do so, and increases exponentially when any of these attackers is using a method more effective than simple random generation or brute-force. Sophisticated hacks have a better chance than these figures would suggest.

~ the chances of winning the Powerball lottery are something like 1 in 300 million and it happens all of the time.
People win all the time because the chance to win is equal to the number of tickets sold. It's not rare that someone wins, it's rare that you win.

Back to Bitcoin: I can generate a random private key right now. The chance of me finding that key: 1 in 1461501637330902918203684832716283019655932542976 !
But the chance of me finding a key: 100%.

When comparing Bitcoin to the Powerball lottery, I think it's safe to say you're more likely to win that lottery without buying a ticket, than finding a collision on a private key.

No you can't! It's easy to confuse a theoretical chance with a real chance.
Example: You can randomly generate my phone number, call me, and tell me my creditcard number. Although this sounds far fetched, it's still 1461501637330902918203 times more likely than finding a private key collision.

That's why it's very important to generate your private keys at random. If your random isn't random, someone else can reproduce it.

We just found a really interesting ETH private key:

Code:
Privkey: 64e604787cbf194841e7b68d7cd28786f6c9a0a3ab9f8b0a0e87cb4387ab0107
Address: 0xf46b6b9c7cb552829c1d3dfd8ffb11aabae782f6

https://etherscan.io/address/0xf46b6b9c7cb552829c1d3dfd8ffb11aabae782f6

What's cool about this one?

It received 21 ETH from the genesis block! Check the first transaction on the blockchain (link above).

How did we find it? Wordlists, math and blockchain APIs (our own scripts).

Pseudocode:

keccak-256sum("ABC123*") = 64e604787cbf194841e7b68d7cd28786f6c9a0a3ab9f8b0a0e87cb4387ab0107

(* The phrase is actually NOT "ABC123", but you should be able to reproduce this one quite swiftly, with a basic wordlist.)

From there, it's two relatively simple operations, including elliptic curve, to derive the public address.

Pretty awesome, no?

People win all the time because the chance to win is equal to the number of tickets sold. It's not rare that someone wins, it's rare that you win.

Then I misunderstand the Powerball, because I'm talking about matching the numbers randomly pulled. Your chances of matching random numbers would be unaffected by the random numbers that others have chosen. Their "guesses" do not make your guess any more or less likely to be correct. Again, I might not understand how lotteries work I guess, but this is how I understand it. How are the chances equal to the tickets in a lottery of random numbers? More tickets makes it more likely that someone wins, but it wouldn't make your chances vary.

When comparing Bitcoin to the Powerball lottery, I think it's safe to say you're more likely to win that lottery without buying a ticket, than finding a collision on a private key.

You're over exaggerating, unless we're operating on the assumption that you can win with a stolen ticket, or something? I do see your point though.

Humans are very bad at creating random keystrokes.

Bee Boop.

It's easy to confuse a theoretical chance with a real chance.

Apparently, because I do not know the difference. I've thought on this for hours and I cannot figure out the riddle. Help me understand theoretical chance Vs. real chance, genuinely, I am interested.

Example: You can randomly generate my phone number, call me, and tell me my creditcard number. Although this sounds far fetched, it's still 1461501637330902918203 times more likely than finding a private key collision.

Show your work for this math problem. What are the odds of me randomly generating your phone number, credit card and catching you at a good time for a phone call?  Wink
Since I'm illiterate on vocabulary and semantics, collision = randomly generating a previously randomly generated Private Key, right?

That's why it's very important to generate your private keys at random. If your random isn't random, someone else can reproduce it.

Humans are almost as bad at programming random number generators as they are typing random numbers.

More tickets makes it more likely that someone wins, but it wouldn't make your chances vary.
I clearly don't live in a Powerball country, I was assuming it uses tickets.
Anyway, the same applies: the chance that you win is small, but the chance that someone wins is quite large (I don't know the details of the lottery).
For the sake of argument, let's say the chance that someone wins is 10%.
For Bitcoin, even if a billion people search for collissions, the chance that someone finds one is stil 0.00000000......0001%.
That's what makes it so unlikely to ever find one.
In the Powerball lottery, a large part of the search space is covered. In Bitcoin, only a very small fraction is covered.

Quote
You're over exaggerating, unless we're operating on the assumption that you can win with a stolen ticket, or something? I do see your point though.
I was thinking about finding a ticket. I think it's a safe assumption that some tickets are lost, out of millions of tickets. Let's put the chance of finding a ticket at 1 in a million, that still makes it billions times more likely to win with that ticket than finding a collision.

Quote
Apparently, because I do not know the difference. I've thought on this for hours and I cannot figure out the riddle. Help me understand theoretical chance Vs. real chance, genuinely, I am interested.
I may have made up the difference for the sake of argument. Real chance: it won't happen. Theoretical: it might happen. But the chance is so low that you can safely say it won't happen anyway (I read someone else explain this better once).

No, you can never prove you found them independently. A collision means having two private keys that both produce the same address.

I figured this is what you were getting at, point taken.

I was thinking about finding a ticket.

That's not very fair, in our context! That would be similar to leaking your Private Key, and the person using it claiming to have found it randomly (seems to be the case more often than not).

I may have made up the difference for the sake of argument.

Blasphemer!
If a concept is valid and unaccounted for, then I have no problem with you "making it up". I was just genuinely puzzled at the concept.

Real chance: it won't happen. Theoretical: it might happen.

I was unaware of your prophetic abilities, Mr. Loyce. Shocked Help me peer into the nether and see what is and is not to happen.

1 in 10^11 if you don't know my country
1 in 10^16 for my creditcard

Easy enough, credit cards are 16 digits with 10 possibilities per digit. Maybe the math is easier than I thought, fair enough.

About 100% for calling at the right time.

Are you hitting on me, Loyce?

No, you can never prove you found them independently. A collision means having two private keys that both produce the same address.

Oh, well than that changes everything. I'm talking more about acquiring a Private key, rather than a collision; I'm not technically inclined enough to comment on that, yet.

Wait a minute. I'm not talking about randomly generating private keys like

Code:
openssl rand -hex 32

and luck out a la (Powerball)^128. We all know the odds for finding a positive balance address that way is practically close to infinity, even if you had the computational power to check a billion addresses per second.

I'm talking about way to significantly reduce the entropy. Or completely remove it, such as finding images of paper wallets that people frequently - those were the days - used to share on Instagram, Imgur, Flickr and so forth.

Take this one, for example. It had more than 2 BTC in October 2015:

https://www.washingtonpost.com/wp-apps/imrs.php?src=http://img.washingtonpost.com/blogs/innovations/files/2014/11/IMG_20141027_185706.jpg&w=1484

Another way is (was) brainwallets, maybe the stupidest contribution to the bitcoin ecosystem. A famous example is sha256sum("mike") that gives (I'm by no means taking credit for this one):

Code:
64b4d0f47c93ce23d157e68a58767356283dc9b63c459d45d0e0e39b3a64b9b9
5JadzKfQLiM4v5dpqE3J5knhkZdnug6FRmjiCxpnPMAWix11rWR
144BBhjaTofkGJzCG7opHyG5t5HP2boUXc

https://blockchain.info/address/144BBhjaTofkGJzCG7opHyG5t5HP2boUXc

After the 2016 release of brainflayer and this instructional video (recommended viewing!), I assume every possbile and impossible wordlist has been used to sweep the blockchain clean of brainwallets, in a global script kiddie joint venture.

However, I might take credit for Smiley

Code:
echo -n "8" | keccak-256sum -l | tr -d ' -'

which leads us to this Ethereum address

Code:
e4b1702d9298fee62dfeccc57d322a463ad55ca201256d01f62b45b2e1c21c10
dc39020c132047dbff55bcb81aeadccc2b042b35becdd9e6a97f0e86a84785e6c96f252986cdb081103612617754ff45122e34a0c3023e26587ac1a0eba7508e
0xe0fc04fa2d34a66b779fd5cee748268032a146c0

https://etherscan.io/address/0xe0fc04fa2d34a66b779fd5cee748268032a146c0

which was active only 57 days ago.

Ethereum is perhaps even more interesting than bitcoin, because of tokens and smart contracts, some of which you can easily dump on exchanges. I simply assume lots of people are sweeping low entropy ETH addresses for such tokens.

My main point is that there are other and much less explored methods, that I work on for time to time when I have some spare time. I'm done with brainwallets and Google Image, but still have one or two aces up my sleeve.

It would be cool to hook up with others who are into the same thing. I'm fairly certain you are out there. Step forth!

What I don't get though, is why it confirmed the transaction with 152.47 sat/B, and not the older transaction with 446.43 sat/B! Miners are supposed to take the highest fee.

For sure there are still people who do strive and hoping to get some jackpot into those wallets who do have balances but i do think

that most of them completely stop yet its pointless on hunting out btc private keys that do have corresponding balance considering on the odds.

I just started private key hunting a few days ago when I realized that BTC key generation is only pseudo random. It instead generates similar keys based on what keys have already been generated and used (this is where I realized it can be exploited). Why it does this I'm not sure, but it does nonetheless. Not going to give much more information until I make a large profit myself as I said I only realized this a couple of days ago. I've already found hundreds of keys with transactions in the past, and a couple with actual balances (dust).

take the odds of winning a lottery, divide them by millions. then divide that result by millions, and continue calculating that for the rest of your life. you still haven't come close to the odds of finding a private key with a balance in it.

@Flangler  - Not pointless? Well I do hope you have enough computing power, and the lotto comparison? Nah, finding a BTC private keys is way more difficult so the odds is far more difficult as compare to winning a lotto.

What are you going to do with there private keys?
You should not think that you can steal any coin from just guessing other people private keys because in wallet generators, after number one is not number two. So that this kind of action is such a waste time.

Everything that can happen, will happen. And finding a private key with a balance can happen, however small the chances are. Therefore it will happen. The odds are small but that doesn't make it impossible, I don't think that people seem to understand that just because the odds are greatly against the possibility of it happening it doesn't mean that someone on their first try on keys.lol can type in a random number and find a wallet with a huge balance attached to it. I personally have created a webscraper running that randomly check private keys so if I never find anything major it's cost me basically nothing but the time it took to create the scraper which was only a few minutes. Not even electricity as my pc runs 24/7 anyway

Is it possible? Yes
Is it probable? No

You clearly don't understand :
1. How big is 2^256 possible private key and 2^160 possible bitcoin address. Please calculate how long it'd took to get all possibility with today's supercomputer.
2. Most wallet uses CSPRNG which won't let people guess your private key easily.

Simply brute-force all possible permutation won't get you anywhere, you must reduce space search either by finding flaws on CSPRNG used by a wallet or knowing whether a user use insecure way to generate his bitcoin address/seed.

The point isn't to brute force in attempting to crack a single address, it's to use an algorithm that generates random private keys and the possibility is still there that on the very first try the key can be one that is tied to a large bitcoin address. I've done it and am doing it and have generated some addresses that match with already created addresses that have been used and a couple that have had small balances in them so it's not like it never happens. The only thing that makes it not so noteworthy is that it hasn't been tied to an account with 50+ btc or something, but the odds that I and others even reached one with an already used balance proves that private key collision is a common occurrence even given the trillions to 1 odds.

Yeah it can happens but it's not common (how do you define common btw?).

Phishing give you better odds than looking for private key. But for sure if it's just for fun, let's try to find an address with 0.11111 BTC in it!

There's only one way to prove a private key collision: show 2 different private keys that both produce the same address. Nobody has been able to do that yet.

You can't brute-forcing a random private key. The only way to find it, is if it's not really random (or if someone leaks it).

That's not what a collision is, a collision is two separate generators generating the same private key that points to the same address. Not two different keys pointing to the same address. The private key is the root of an address. The address is simply the hash of that private key.

address is not hash of private key, it is hash of public key. and what you explained (2 different entities find the same address with 2 different keys) is only one type of collision. the other type is indeed 2 different entities finding the same private key. the space they are in are different. the first one is in 160 bit and second is in 256 bit and both of them are huge enough to be considered impossible.

that topic is only solving a puzzle, it has nothing to do with collision despite what the name suggests! they have been basically searching from private key = 1 and incrementing it 1 at a time checking whether the result matches the puzzle addresses that were placed there to be found.

That is NOT what I explained, two different private keys will never link to a single address. But two different scripts can and have on several occasions generated identical private keys that have been tied to already used, and in some cases wallets with balances.

Secondly, It's a hash that roots from the private key, same difference.

Shouldn't there be, theoretically, a "tipping point", i.e. mining difficulty becomes so high that it would make more sense to try to find a private key instead to mine?

Wrong, there are 2^256 possible private key permutation, but there are only 2^160 possible address permutation.
Even though i never see any cases where 2 different private keys leads to same address, it's possible since there's less possible address permutation than possible private key permutation.

If my calculation is right, 1 address has about 2^96 corresponding private key.

But two different scripts can and have on several occasions generated identical private keys that have been tied to already used, and in some cases wallets with balances.

Only applies if the script uses weak random algorithm/function. Wallet these days use more random algorithm/function which is cryptography secure.

Also not true, BTC addresses can and do vary in length. There will never be two private keys that match the same address.

e.g

Two Valid addresses {

15PLdWhPDFCyAwMF78SebDAeRRMva8Tgop

1SArTJ5PBwq69x9NHdpGVcBqv9eCmYcYg

}
Also it is no more likely to crack a weak private key than a 'strong' private key through 'RANDOM PRIVATE KEY' generation, not brute forcing. We are not speaking about brute force attacks.

I find this really hard to believe, especially since you imply it's happened more than once. Are you generating truly random numbers, between 0 and 2^256? There's (almost) no way you could coincidentally generate a random private key which matches a funded address. Can you provide proof by showing the addresses and a signed message?

Here's a random private key generator. Feed the output to brainflayer -x -t priv, or a suitable tool that takes a raw private key.

Code:
// output random hex digits as a 256 bit priv key

#include <stdio.h>
#include <stdint.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/time.h>

uint64_t timeuseconds() {
        struct  timeval thistime;

        gettimeofday(&thistime, NULL);
        return((thistime.tv_sec * 1000000) + (thistime.tv_usec % 1000000));
}

int main() {

        int i;

        srandom(timeuseconds() );

        while (1)
        {
                for (i = 0; i < 16; i++)
                {
                        printf("%04lx", random() & 0xffff);  /* not cryptographically secure */
                }
                printf("\n");
        }

Like Keys.lol / Privatekeys.pw and thegalacticlottery I don't know some coding that's why I only use this website. 3 days of hunting and still nothing. Open about 60 browser in my pc and 40 browser in my laptop running with script to auto refresh and if it read an transaction it auto stop with message and alarm. but thegalacticlottery I only open 1 browser in my pc and laptop. and while searching for browser I use my PC to play games Cheesy only the laptop is wasting energy.

So whats your conclusion? Searching for wallets that do have balance is pretty hard eh?

Any Hunter here. I saw a lot of good hunter here. I am just using a lottery system. Like Keys.lol / Privatekeys.pw and thegalacticlottery I don't know some coding that's why I only use this website. 3 days of hunting and still nothing. Open about 60 browser in my pc and 40 browser in my laptop running with script to auto refresh and if it read an transaction it auto stop with message and alarm. but thegalacticlottery I only open 1 browser in my pc and laptop. and while searching for browser I use my PC to play games Cheesy only the laptop is wasting energy.

You're really just wasting electricity. Even if your computer was able to search a thousand or a million times faster, the chances of ever finding a match within your lifetime are effectively zero. You'd have more chance of winning a (real world) lottery.

Is it possible to find addresses with balances or (more likely) which have had balances in the past? Yes: look up SHA256 brain wallets, broken key generator code, deliberately weak keys, user mistakes, etc.

Can you find them by generating random keys via a website? No. (The code I posted above generates random keys - it was meant to be a joke. Smiley )

if you want to waste electricity and lower the lifespan of your computer hardware by putting a lot of continued pressure on them then  at least start mining altcoins! that way you can at least earn something for real instead of wasting your time on something that obviously not going to work not just in a couple of days or years or decades,... it won't work for a million years!

Why don't you try to find the next Bitcoin block? There's an instant 12.5 BTC reward waiting for you!
The chances of finding it with your computer are of course practically zero, as ASICS made GPU mining useless years ago, but it's still much more likely than finding a random private key.

Lol I mess around with Keys.lol for like 1 hour one time. I stumbled upon it by accident. I would have to say, In the little time that I have tinkered around with it. I would have to say it IS PRETTY HARD LMAO,

From the math I have read here it's probably not even worth the time. lol

The program that I posted here https://bitcointalk.org/index.php?topic=4345245.msg51294948#msg51294948 will, when paired with brainflayer, search random private keys at a rate of about 120,000 Bitcoin keys per second on a single i7 core. That's just over 10 billion per day.

The chances of ever finding a match for a random 256 bit key, even when checking 10 billion keys a day, even if you're using multiple cores to double/triple/quadruple etc that rate, even if you're using a GPU assisted program that focuses on a small set of addresses and runs at 500 times that rate, is still virtually zero.

It's absolutely not worth the time.

23trillion pupkey / s
check out my profile

the thing you are trying to sell seems to be only working for that puzzle transaction and when you have the public key not in general which is the case of the comment you quoted and also is the general theme of this topic. not to mention that OP started this topic mainly as a brainwallet stealer!
