Like the other comments say, RBF intends to replace the pending, original tx with better fees. You can’t replace the original tx once it’s been mined, since the blockchain is immutable

Yeah I was thinking about those ransomware cases that have been averted by redirecting transactions before confirmation, thus saving the money and the data

Meaning the attacker returns the stolen data before the transaction is confirmed in the blockchain? Nice move, morons… lol

No no, I mean if the victim could broadcast another tx with the original utxo but with a higher fee, so miners will look for that transaction instead of the earlier one, and that way the funds can be kept by the victim, and still the ransomware unlock the data. I do not know if this is possible. That is what I want to know.

You can broadcast a replacement transaction directly to a miner if you know their IP address.
Whether any mining pools would consider that transaction, I've no idea. The standard bitcoin core client would reject the transaction (i.e., not add it to the mempool) since it would be considered invalid it includes one or more UTXOs that have already been spent.
And the fee for that replacement transaction, to be sufficient incentive for a miner/pool to consider it, would need to be at least as much as the next upcoming block could be. So ... currently 6.25 BTC + possible fees that would be mined.
And how does invalidating a transaction with just one confirmation and mining of a replacement transaction help you? Most exchanges and such are a minimum of 3 confirmations, no?

Yes, thanks. Indeed 3 or more confirmations are required. Maybe after 5 more halvings (0,19 btc of subsidy) that strategy could be affordable.

NO, before it’s confirmed (mined)

Its to replace the fee so it will be mined if your TX is way back in the mempool
