Planting a lookalike address in your history so you copy the wrong one.
The attacker generates an address whose first and last characters match one you use often, then sends you a zero value transaction so it appears in your history.
Later you copy an address from your transaction list, glance at the first and last few characters, and send funds to the attacker instead.
Always verify the full address, or use an address book and name service names rather than copying from history.
That the attacker somehow accessed your wallet. They did not. They sent you a worthless transaction from an address that looks like one you use, so that later you copy it out of your own history. The defense is never copying from transaction history.

Some of these land faster in conversation than in writing. Sessions are one to one and you can ask anything, including the things that feel too obvious to ask.
