>For the double spend to occur, you would need access to the seed ( private key) which the victims had and are trying to outrun the attacker in the case you were describing.

So it works a bit like replace-by-fee on bitcoin? There is no mining on IOTA so what is the possible time frame? do you have more detailed technical information how this works? Thanks

New transactions are selected randomly to be verified. So in case the attackers transaction is still not confirmed there is a chance to outspend him by having the private keys. I find this useful in understanding the confirmation/consensus mechanism. https://forum.iota.org/t/iota-consensus-masterclass/1193
