Jackpotting is a type of cyberattack where criminals target automated teller machines (ATMs) to make them dispense all their cash. Attackers typically gain physical access to the ATM and install malicious software or hardware, allowing them to override security controls. Once compromised, the ATM is instructed to release its cash reserves on command. This method can result in significant financial losses for banks and is a growing concern in the cybersecurity industry.
