Check the user that I've just linked to here and also read the whole thread that I've just linked.
The user claims that he doesn't use bitcoins and as I see it, is a pro-bankster.
Cool, right? He seems to have a lot of knowledge regarding that certain attack vector on bitcoin.

1) I use bitcoins. But I do not hold them. Sorry for some misunderstanding. My English is not perfect.
Let me give an example:
I eat watermelons. But I do not buy watermelons for investing.
Because I do not think that I would be able to sell the watermelon tomorrow with profit.
And I advise to everyone not to invest and hodl watermelons.

2) I am not pro-bankster.
I just say, that keeping money in pockets is better than investing in watermelons

From what I can see, it's somebody who is out to destroy bitcoin. What is there to gain by carrying out the attack only to cause inconvenience to the users. Obviously it is the trust and reputation factor that is at risk here because people see bitcoin as a reliable payment system. I'm also surprised that after so many years there is still loophole in the system that can be exploited.

The problem is that a known bug in the bitcoin protocol has festered for years. If the "core" developers had been doing their job, this problem would have been fixed long ago.

The attacker can't steal your money. All the attacker can do is change your transaction ID, then re-transmit it very quickly to send Bitcoins to the same address they were originally intended to be sent to. One of the transaction IDs has to be accepted by the network,and the other has to be discarded. Your Bitcoins still get sent to the address they were intended to go to, but sometimes they arrive with a different transaction ID than you were expecting if your transaction gets attacked.

Yes that's all they can do but it affects certain transaction which rely on the transaction ID, for example if you're live betting and you send in a bet, it gets accepted but then the other one is sent with different ID and the 2nd one gets confirmed and by that time the odds have changed, one other affect of it is, someone I know reloads his mobile using BTC, so he sended the BTC and waited but never received his reload because his transaction under original ID was never confirmed and the other one did but the website didn't recognize that as it relies on the Tx ID.

And OP it is still going on, I did many transactions today and couple of those were resent using different ID and thankfully it didn't affected anything, other than the Blockchain.info warning saying that this address has double spends.

I find it strange that all these technical loopholes have been found recently, and not a lot before that. I wonder how all of this fits into the Bitcoin Core vs Bitcoin XT debate.

It's pure speculation, but things has gone crazy, since this whole split has happened. The person doing this malleability attack has a lot of technical information of the inner

workings of Bitcoin, so it's probably a engineer or a developer?

Isn't this the same old transaction malleability that has already happened last year? Markets have then reacted much wilder and we have seen major drops in price. I thought this is the same old problem.

As I know a BIP 62 is here to solve this problem but this BIP 62 still hasn't been finished and deployed successfully!

Bitcoin has been growing extremely rapidly the past few years, and this brings a lot more pressure to any faults and flaws within the code.
More eyes and more incentive these days.

It is still ongoing as of this moment, and the certain user who performed it is this one: https://bitcointalksearch.org/user/amaclin-197593

Anybody with a little bit of programming/bitcoin knowledge can easily perform this; hence there are many people doing it in an attempt to force improvement through the bitcoin network because it has already proven to be detrimental.
It is still occurring.
