4. The malicious actor removes an extra signature from the vulnerable transaction.
Unlike creating a signature for different transaction instructions, this does not require a large amount of computational work. It can be done in much less time than it takes to generate a signature in the first place.
Alternatively, an authorized signer whose signature is not already part of the transaction could add their signature to the vulnerable transaction's list of signatures. Depending on the sender's multi-signing settings, this can be in addition to removing other signatures from the transaction.
Alternatively, an authorized signer whose signature is not already part of the transaction could add their signature to the vulnerable transaction's list of signatures. Depending on the sender's multi-signing settings, this can be instead of or in addition to removing other signatures from the transaction.
The modified list of signatures results in a different identifying hash. (You do not have to calculate the hash before you submit to the network, but knowing the hash makes it easier to check the transaction's status later.)
