Abstract: A fraud remediation tool includes a memory, a network interface, a fraud detection engine, and a clearance engine. The memory stores a plurality of fraud detection rules. The network interface receives a first transaction and a second transaction. The fraud detection engine determines, based on the plurality of fraud detection rules, that the transaction is fraudulent. In response to the determination that the transaction is fraudulent, the fraud detection engine stops the transaction, blocks use of the first card, and communicates a first message to the user indicating that the card is blocked. The clearance engine receives, from the user, a response to the message indicating that the transaction is not fraudulent. Based on the response, the clearance engine releases the block on the second card and the block on the first card.

Abstract: In an embodiment, a system contains a payee data database configured to store payee data that contains intended payee information and a fraud marker engine configured to determine a fraud marker based on the payee data, wherein the fraud marker identifies an activity including performing a transaction benefiting a payee account, wherein a plurality of payor accounts have, within a defined time frame, changed their intended payee information to include the payee account. The system also contains a fraud marker scoring engine that determines a fraud score for the fraud marker based a likelihood that the activity is fraudulent or a severity of the activity, and an activity monitoring and matching engine configured to monitor activity of a first payee account and a first payor account, determine that the monitored activity matches the fraud marker, and institute a block, cancellation, or hold on the monitored activity based on the fraud score.
