Stop BEC Before Settlement Executes
JIL stopped a high-value BEC redirection attempt by requiring intent-bound attestations and enforcing corridor policy gates before execution.
Benchmark-based analysis
BEC succeeds when approvals are detached from instructions. JIL binds approvals to the payload, forces re-attestation on change events, and creates a defensible evidence trail.
A last-minute beneficiary change arrived through a compromised email thread. Traditional approvals could not prove that the instruction was legitimate.
- Blocked a fraudulent redirection attempt prior to execution
- Reduced manual verification loops from hours to minutes (target KPI)
- Generated an audit-grade evidence pack for compliance and incident response
Why this problem persists
BEC attacks win when approvals are detached from the instruction payload. Attackers exploit "approve the email" workflows that never cryptographically bind the approval to the actual settlement instruction. In this scenario, a sophisticated BEC actor compromised a vendor email thread and injected modified banking details into an otherwise routine payment approval chain. The treasury team had no way to distinguish the fraudulent instruction from a legitimate one - because the approval workflow validated the email, not the instruction payload.
The JIL approach
JIL enforced a corridor rule: no final settlement without sender + receiver intent attestations bound to the instruction payload. When the beneficiary details changed, the corridor required step-up verification and re-attestation. The fraudulent instruction failed the attestation check because the altered beneficiary could not produce a valid cryptographic binding. The system generated an evidence pack documenting the attempted redirection, the failed attestation, and the policy decision - all indexed by receipt ID for instant retrieval.
Every settlement event produces verifiable evidence
Before vs After
- Callback chaos
- Screenshot compliance
- Disputed approvals
- Hours of manual verification
- Enforced proofs
- Deterministic receipts
- Defensible evidence packet
- Minutes to verify
What Made the Difference
Corridor policy gates
blocked disputed instructions before execution
Step-up rules
for beneficiary changes and destination novelty
Portable evidence
reduces audit friction and dispute resolution time
Deterministic receipts
unify ops + risk + compliance around a single timeline
Deployment path
Expand to all high-risk corridors, add automated "change-of-bank" triggers, and standardize quarterly evidence exports for audit.
