Today we’ll see How to perform and prevent Dos-Attack by rejecting Ether.
I’ll show a practical example of a contract vulnerable to dos attack by rejecting ether and how to prevent this attack by using a design pattern called pull over push pattern
we’ll perform dos attack where the currentLeader is a contract address (the attacker contract) that cannot receive ether.
And when anyone else tries to become the current leader they can’t because the transaction will revert because our contract cannot receive ether(forever).
