About the programme
Course Overview
Subscription fraud rarely announces itself: a fraudulent application looks almost identical to a genuine one until the device is used for bypass fraud, the handset is resold, or the account is used to intercept a one-time passcode meant for someone else's bank. This course focuses on stopping subscription fraud at the point where it can be prevented most cheaply, the application and activation stage, by combining identity verification with behavioural and device-based fraud scoring. Participants examine document verification and biometric matching techniques used to confirm an applicant's identity, and design decision rules that route uncertain applications to manual review rather than auto-approving or auto-rejecting them. Sessions cover SIM swap and porting fraud, including the social engineering and insider-assisted attacks used to hijack a number, and the verification steps that make hijacking harder without frustrating legitimate customers. The course also covers device fingerprinting, velocity checks across applications, and building a fraud scoring model that improves over time as confirmed fraud cases feed back into the rules.
Expected Learning Outcomes
Build fraud scoring rules that route high-risk applications to manual review without blocking genuine customers.
Identify SIM swap and porting fraud patterns and design verification steps that resist social engineering.
Apply device fingerprinting and velocity checks to detect coordinated fraudulent application attempts.
Investigate confirmed fraud cases and feed findings back into scoring rules to reduce future losses.
Balance fraud control friction against genuine customer conversion and onboarding experience.
Report fraud detection performance and loss trends to risk and commercial stakeholders.

01Identity Verification at Application
2 sessions · 8 points
Session 1Document Verification and Biometric Matching
- Evaluate document verification techniques for detecting forged or manipulated identity documents.
- Configure biometric matching between a live selfie capture and the presented identity document.
- Set confidence thresholds that determine automatic approval, rejection or manual review.
- Handle edge cases such as damaged documents, low-quality images and expired identification.
Session 2Risk-Based Decisioning for New Applications
- Design a risk-based decision engine that weighs identity confidence against application characteristics.
- Set manual review workflows for applications that fall into an ambiguous risk band.
- Track approval, rejection and review rates to detect drift in the decision model over time.
- Balance verification friction against genuine applicant drop-off during onboarding.
02SIM Swap and Porting Fraud Defences
2 sessions · 8 points
Session 1Understanding SIM Swap and Account Takeover Techniques
- Analyse how social engineering and insider-assisted attacks are used to execute SIM swap fraud.
- Map the customer journey from initial contact through verification to SIM replacement or porting.
- Identify the account takeover consequences of a successful SIM swap for downstream services.
- Review real attack patterns to understand where existing verification controls typically fail.
Session 2Hardening Verification for SIM Swap and Porting Requests
- Design step-up verification for SIM swap and porting requests that resists coached social engineering.
- Configure out-of-band confirmation and cooling-off periods for high-risk account changes.
- Set alerts to notify customers immediately when a SIM swap or port request is initiated.
- Train frontline staff to recognise pressure tactics used during fraudulent swap requests.
03Device and Behavioural Fraud Signals
2 sessions · 8 points
Session 1Device Fingerprinting and Application Velocity Checks
- Apply device fingerprinting to detect the same device used across multiple suspicious applications.
- Configure velocity checks that flag unusual bursts of applications from related identities or locations.
- Cross-reference application data against known fraud indicators such as reused addresses or emails.
- Distinguish coordinated fraud rings from legitimate high-volume application sources such as retail partners.
Session 2Building and Tuning a Fraud Scoring Model
- Combine identity, device and behavioural signals into a single weighted fraud score.
- Backtest scoring rules against historical confirmed fraud cases to measure detection accuracy.
- Tune score thresholds to balance false positives against undetected fraud losses.
- Establish a feedback loop where investigation outcomes retrain and refine the scoring model.
04Investigation, Governance and Reporting
2 sessions · 8 points
Session 1Investigating Confirmed and Suspected Fraud Cases
- Build a case investigation workflow that captures evidence, decisions and outcomes consistently.
- Coordinate with law enforcement and industry fraud-sharing schemes where legally appropriate.
- Recover losses where possible and document write-off decisions for finance reporting.
- Close the loop by updating watchlists and scoring rules based on investigation findings.
Session 2Fraud Performance Reporting and Stakeholder Alignment
- Report fraud detection rates, losses avoided and false positive rates to risk committees.
- Present the commercial trade-off between fraud control strictness and customer conversion.
- Track regulatory obligations around identity verification and data retention for fraud cases.
- Align fraud, compliance and commercial teams on acceptable risk appetite for new channels.
