A counterattack method against a hacked node in a controller area network (CAN) bus physical layer includes: setting node IDs (NIDs), which are different unique IDs, for each of a plurality of nodes connected to a CAN bus line; determining that an error frame is generated when at least one of a node using a forged NID, a node using a different NID, and a node using a non-existent NID is found; increasing counts of a transmit error counter (TEC) and a receive error counter (REC) of a transmitting node and a receiving node whenever the error frame is generated; and allowing a node of which the count of the TEC or REC is greater than a set threshold value to enter a bus-off state to block the node.
