Real-time A2A fraud: are siloed controls still enough?

TL;DR: Real-time account-to-account fraud is outpacing siloed bank controls because criminals exploit instant payment rails, social engineering and fragmented visibility, according to Feedzai, while ACI Worldwide projects over 575 billion real-time payment transactions by 2028. Shared intelligence and milliseconds-level decisioning now matter more than isolated detection in fraud programmes.

Editorial analysis by NHI Mgmt Group, based on content published by Feedzai: “How Network Intelligence Is Reshaping Real-Time A2A Fraud Prevention”.

Key questions

Q: What breaks when fraud controls are built for batch review instead of real-time payments?

A: Batch-oriented controls lose effectiveness when payment decisions complete faster than human queues can react.

Q: Why do social engineering attacks bypass many traditional fraud controls?

A: Social engineering succeeds because the real user is still on the real device, using valid credentials and a normal location.

Q: How should banks measure whether network intelligence is actually improving fraud prevention?

A: Look for reduced time-to-decision, earlier detection of suspicious beneficiaries, fewer false negatives across receiving banks and faster adaptation to new scam patterns.

Practitioner guidance

• Prioritise outbound transaction scoring Score both sending and receiving activity before settlement, not only the transaction that originates inside your own environment.
• Build shared-signal workflows with network partners Exchange risk indicators, beneficiary patterns and mule signals in a privacy-preserving format so cross-institution patterns are visible in time to act.
• Add beneficiary risk to payment decisions Include high-risk beneficiary monitoring, mule detection and repeat-recipient analysis in the decision path for instant transfers.

Bottom line: Real-time A2A fraud exposes a control gap where instant settlement outpaces the ability of single-bank defenses to judge trust in time.
