Pre-Settlement Flash Audit for Perth Firm Principals: Detect Settlement Hijack Indicators Against ISO 27001 Controls

You are the principal. Your name is on the trust account, the practice certificate, and the firm’s letterhead. A single settlement that goes sideways — funds redirected, a buyer’s deposit landing in an attacker-controlled account — lands on your desk on Monday morning, not your settlement clerk’s. The Pre-Settlement Flash Audit gives you a one-shot, principal-level view of whether a specific high-value settlement file shows the structural indicators of a hijack attempt, scored against the information security controls your firm is expected to operate.

Why it matters now

Settlement hijack is the end-stage of a payment-redirection attack: an attacker who has observed or compromised the communication channel between buyer, seller, agent, lender and firm intercepts a payment instruction and substitutes attacker-controlled banking details, usually in the final two weeks before settlement. ISO/IEC 27001:2022 — the international standard for information security management systems — requires an organisation to identify, assess and treat information security risks across people, process and technology (ISO/IEC 27001:2022, Information security, cybersecurity and privacy protection — Information security management systems — Requirements). For a Perth firm principal, the practical test is not whether your firm holds an ISO 27001 certificate, but whether the controls the standard describes — access control, communications security, supplier relationships, incident management — are actually evident on the file. The Australian Cyber Security Centre publishes general guidance on payment-redirection and business-email-compromise threats at https://www.cyber.gov.au/, and the ACCC’s ScamWatch service at https://www.scamwatch.gov.au/ continues to track payment-redirection as one of the higher-loss scam categories against professional services.

The 5-minute view

• Settlement hijack typically presents in the final 7–14 days before settlement, when banking details are exchanged or amended
• ISO/IEC 27001:2022 frames information security as a management-system obligation: identify risks, apply controls, monitor effectiveness, improve
• Annex A of ISO/IEC 27001:2022 groups controls under four themes — organisational, people, physical and technological — all of which intersect a settlement workflow
• Control domains most relevant to settlement hijack include access control, communications security, supplier and third-party relationships, and incident response
• Out-of-band verification of payment instructions (a phone call to a previously known number) is the single most consistent recommendation across regulator guidance
• A principal-level audit looks at the file the way a regulator or insurer would: what controls existed, whether they were applied, and what evidence remains
• The Flash Audit is a one-shot diagnostic on a single nominated settlement file — it is not an ISMS certification audit and does not substitute for one

What DRMO does about it

The Pre-Settlement Flash Audit is a single-transaction diagnostic delivered at principal level against one nominated settlement file. You submit the file reference, the related correspondence chain covering payment instructions, and a short questionnaire on your firm’s existing controls. We run a fixed-scope review mapping the file against the ISO/IEC 27001:2022 Annex A control themes most relevant to settlement hijack — access control on the firm’s email and document systems, communications security on the inbound and outbound channel carrying payment instructions, supplier and counterparty verification, and incident-response readiness if an indicator is found. The deliverable is a 15-page PDF audit report identifying the specific indicators present, the control gaps the file exposes, and the recommended verification steps before funds release. This is the same diagnostic that runs as Step 2 of the Pre-Settlement Shield consulting engagement, productised for single-transaction principal use.

The deliverable

• 15-page PDF audit report scoped to one nominated settlement file
• Executive summary written for the principal: Red / Amber / Green status and the recommended next action before funds release
• Per-indicator review mapped to ISO/IEC 27001:2022 Annex A control themes (organisational, people, technological)
• Control-gap summary covering access control, communications security, and counterparty verification on the file
• Verification checklist for the settlement team to complete and sign before funds release
• Delivered via email within 1 business day of file submission and payment
