Abstract: Embodiments may include receiving a request including transaction data to evaluate a transaction as part of a charge path that processes at least a portion of the transaction; processing, by a set of blocking machine learning models, a portion of the transaction data to generate a set of blocking scores for the transaction; retrieving, from a memory, a set of card testing attack (CTA) scores associated with the transaction, the set of CTA scores indicative of an occurrence of a card testing attack, and the set of CTA scores retrieved based on the transaction data; adjusting a set of default blocking score thresholds based on the set of CTA scores to generate a set of adjusted blocking score thresholds; and determining to allow the transaction based on comparison of the set of blocking scores with the set of adjusted blocking score thresholds.
