Definition

A fraud risk assessment for digital businesses systematically identifies fraud schemes relevant to online and platform business models — account takeover, refund abuse, synthetic identity, insider data exfiltration, and payment redirection — maps them to existing controls, and prioritises analytics tests and audit procedures to detect gaps. It applies ACFE Fraud Risk Assessment Standards (2023), IIA Standard 2120.A2, and aligns to SAMA AML/CFT controls (Chapter 3) and UAE Federal Decree-Law 26/2021 on anti-money laundering.

Why it matters

The pressure on Internal Audit programmes is shifting in specific, observable ways:

• IIA Standard 2120.A2 requires internal audit to evaluate fraud risk exposures; failure to document a formal fraud risk assessment is cited by EQA assessors as a Standards non-conformance.
• UAE Federal Decree-Law 26/2021 (AML/CFT) and SAMA AML Rules impose personal liability on CAEs and compliance officers if fraud risk is not documented and controls validated annually.
• Digital platform fraud losses in MENA average 1.8–3.2% of gross merchandise value (Kroll 2023 MENA Fraud Report); a structured FRA and targeted analytics tests reduce this to 0.4–0.9% within 12 months.
• Regulators (CBUAE, SAMA) are conducting targeted reviews of digital lenders and fintechs; organisations without a documented FRA receive mandatory remediation notices with 90-day compliance deadlines.

Evidence sources to capture

What an auditor or reviewer will sample for — wire each source into your evidence repository before the next review cycle:

• Fraud incident log — internal fraud cases (confirmed and suspected) from the last 36 months with scheme type, loss amount (AED/SAR/INR), and detection method.
• Transaction monitoring system alerts (NICE Actimize, Oracle FCCM) — alert volume, false positive rate, and cases escalated to SAR filing.
• User behaviour analytics (UBA) platform (Splunk UBA or Microsoft Sentinel UEBA) — anomaly detections by risk category and case status.
• Chargeback and dispute log — chargeback rate by payment method and merchant category; rates >0.9% flag potential card-not-present fraud.
• Insider threat indicators from DLP tool (Forcepoint or Microsoft Purview) — data exfiltration alerts by user, volume, and destination.

Recommended next actions

A 90-day plan, sequenced so each step produces evidence the next step depends on:

• Day 0-30: Fraud Risk Officer and Internal Audit co-facilitate a scheme identification workshop using the ACFE Fraud Risk Assessment template; document ≥20 schemes relevant to the digital business model.
• Day 31-60: Rate each scheme on likelihood and impact; map to existing controls (preventive and detective); calculate residual risk score; flag schemes with residual score ≥12/25 for immediate audit.
• Day 61-90: Design analytics tests for top-5 residual risk schemes (e.g. refund-to-original-payment-method ratio >15%, dormant account activation + large withdrawal within 24h).
• Day 90+: Run analytics tests; present FRA report and test results to Audit Committee and CISO; agree control enhancements for high-residual schemes.
• Ongoing: Update FRA annually and after material business model changes; run analytics tests on highest-risk schemes monthly; report fraud KRIs to Board Risk Committee quarterly.

Example metrics

Instrument these and report them monthly to the executive sponsor; sustained adverse trends become board-level conversations:

• FRA updated and Audit Committee-approved annually — 100% of cycles.
• High-residual fraud schemes (score ≥12/25) with compensating controls in place ≥90%.
• Digital fraud loss rate as % of gross transaction value ≤0.9% (target within 12 months of FRA implementation).
• Transaction monitoring false positive rate ≤30% (industry benchmark 60–90%; lower rate indicates better model tuning).
• Time from fraud scheme detection to control implementation ≤45 days for critical schemes.

A the next two quarters working plan

MAST Consulting Group runs this Internal Audit work in four moves. Each move is short, evidence-producing, and signed off by a Lead Practitioner before the next begins.

• Frame (week 1). Confirm scope, regulators in play, and the decisions the work has to enable — referenced against the audit universe. Without that framing, the rest becomes a documentation exercise the audit committee will not read.
• Diagnose (weeks 2–4). Walk through three-year audit plan and engagement letter and scope as they exist today. Capture not just gaps but the design decisions behind every existing control — those are usually where audit findings hide.
• Design (weeks 5–8). Make the contested choices early and pre-clear them with external EQA reviewers (every 5 years). Document the rationale; Internal Audit reviewers care more about reasoned decisions than perfect ones.
• Operate (weeks 9–12). Move evidence collection into issue trackers that the auditees actually use and TeamMate+ / Workiva / Galvanize for audit lifecycle. A control that depends on a separate GRC tool nobody opens will fail within two cycles.

Pitfalls we keep seeing

Across MAST Consulting Group's Internal Audit portfolio, the same recurring failure modes show up cycle after cycle. None are exotic; all are expensive when they reach the audit report.

• Pattern: plan utilisation skewed to easier engagements. What good looks like: the same control evidenced inside the workflow it governs, not separately for the audit.
• Pattern: quality-assurance and improvement programme that is paper-only. What good looks like: the same control evidenced inside the workflow it governs, not separately for the audit.
• Pattern: follow-up that loses momentum after 90 days. What good looks like: the same control evidenced inside the workflow it governs, not separately for the audit.
• Pattern: a universe that lists processes but not the underlying risks. What good looks like: the same control evidenced inside the workflow it governs, not separately for the audit.

Tooling we actually reach for

MAST Consulting Group is deliberately tool-agnostic, but in practice the same shortlist keeps appearing on Internal Audit engagements because the integrations are cheap and the evidence is defensible:

• Power BI for audit analytics — used not because it is fashionable, but because the audit trail it generates is one the reviewer accepts on the first ask.
• issue trackers that the auditees actually use — used not because it is fashionable, but because the audit trail it generates is one the reviewer accepts on the first ask.
• TeamMate+ / Workiva / Galvanize for audit lifecycle — used not because it is fashionable, but because the audit trail it generates is one the reviewer accepts on the first ask.
