A money trail is the path stolen funds take after a fraud, moving through bank accounts, payment services, wallets, cash-out points, and transfers. Criminals often split payments across many hops to hide the source, delay detection, and make recovery harder.
In cyber security, following the money trail is a key investigation method because it can connect technical activity to real people and infrastructure. Even when attackers use fake identities, mule accounts, or crypto services, the payment record may reveal patterns, shared intermediaries, or final cash-out locations. Defenders and investigators use transaction monitoring, account freezes, and cross-border cooperation to trace funds quickly before they are dispersed. A strong money-trail analysis can turn a suspicious login, scam message, or ransomware payment into actionable evidence.
