The attacker would have wanted to entry your non-public key to signal a legitimate transaction. If that occurred and also you noticed the transaction in a mempool then you would broadcast a competing transaction with the next payment charge. It might then be a race to see which transaction acquired mined and included in a block and the attacker’s transaction would have had a headstart (it could have been propagated throughout the community for an extended time period).
This is not technically RBF, RBF typically refers to bumping the payment for a transaction spending to the identical vacation spot.

Sure. All bitcoin transactions that sign RBF (Tx1) will be cancelled (exchange output with yours) utilizing some wallets with Tx2.
Wallets that assist cancellation by RBF:
- Bluewallet
- Electrum
- Sparrow
Tx2 might be changed with Tx3 if the attacker has entry to entire pockets as a substitute of only one key. Attacker may additionally do CPFP for Tx1 with or with out entry to entire pockets. You are able to do CPFP if there was change within the transaction that belongs to your pockets.
Cancellation of unconfirmed RBF transactions would even be attainable in Bitcoin Core if PR #25344 is merged.
