Bitcoin Forum

hello i am a hirosika and i am mechanic engineer.

I tested a bitcoin wallets and i found a security weakness.

i copy wallet with a modified code.

normally, other net hash denied fake coin remittance, but i make a forced admission with closed fake net hash.

and i succeed deposit to exchanges my fake coin.

i will do not open this method to the public but i think some crackers already knew this way.

i am not used an english so i am immature. sorry about that.

well...i think bitcoin need a softfork.

how i contact bitcoin developer?

I don't understand the nature of the vulnerability, but if you found a security issue in Bitcoin Core wallet, you can contact them at security@bitcoincore.org

Otherwise, the problem might be in the exchanges you were using, so you should contact them.

thank you. i send a message to that address.

Please post transaction ID.

Please post more info then you will get an answer from Bitcoin Core development team.

I call bullshit on this one, such vulnerability of faking coins can not be broadcasted on the Bitcoin Network, if I am understanding what he's saying.

this assertion it is too generic.
If you can plz post more infoes and if you have, post transaction id, so we can check on block chain what are you saying.

We can produce fake Bitcoin? I hope it is not real... It would destroy Bitcoin.

This is scary what the actual fuck. But I don't think that is possible though. Blockchain wont accept it

You can submit the bug here: https://github.com/bitcoin/bitcoin

That might a security flaw from the exchange, or are you able to send 'fake bitcoins' to other wallet?

there hasn't been a flaw like this for many years, can you post transactions that show this?

I dont think its easy to make fake transactions, and i think its not possible.
We dont ask to tell us the method you used, but give some proofs, like transaction

The fact that he hasn't come back should say something.  Almost assuredly FUD.

i guess you are on testnet mode .

because you cant just make coins out of nowhere, i mean such coins only come from mining.

and only inputs can be outputs.


send 1000 bitcoins to my wallet 14jp1tXiXbWJE8pxXR9oPhv7kQZqMWZddK
and PM me your paypal address.

to do what is talking about wouldn't you need 51% control over the net?  ???

bitcoin developer is dead already

I bet 1 BTC, that OP's fake transaction "with closed fake net hash" has no more than 0 confirmations.

Haha, it's unfortunate that Op didn't mention about txid from his cracked wallet to exchange but he stated it works which mean it has more than 0 confirmations. Well, I am not sure about his fake coins but at least he tried to contact core developers.
I am wondering how is it going, whether this problem really serious as a leak in blockchain system or not.
