Create Double Spend TX to trick CryptoWall?

[Jude Austin]

Hello,

I was curious, is it possible to create a double spend transaction to trick the Cryptowall 3.0 virus?

I imagine the creator of the virus was smart enough to wait for confirmations...but who knows?

Thank you,
Jude

Bitcoin intentionally makes it very difficult to double spend transactions even when they are not yet confirmed.

While you could certainly attempt a double spend of some sort, there is no way to guarantee that the attacker will see a different transaction than will be confirmed, unless you could arrange cooperation from a significant percentage of the mining hash power on the network.
