The Outlier Lab

Fraud Analyst Onboarding Curriculum

A 30/60/90-day onboarding curriculum for new transaction fraud analysts, sequenced through this vault: money paths, mechanisms, signals, controls, regulation, QA and graduation criteria.

Core components

Design principles

  • Money path first. Every lesson connects back to where value enters, moves and leaves. See Payment Rails Map and Customer Lifecycle Map.
  • Mechanism → signal → control → playbook. The vault's structure is the curriculum's structure (see Start Here).
  • Graded practice before live decisions. Synthetic and historical cases with known outcomes come before production queues.
  • Gradual authority. Read-only, then recommend, then decide with second review, then decide independently, with value limits by stage.
  • QA as teaching. Early QA sampling is heavier and feedback is faster. See Fraud QA Program.
  • Defender perspective. Training explains how fraud works conceptually and how to detect it. It never trains people to commit it.

The 30/60/90 plan

Diagram: Days 1-30: Foundations + supervised decisions, Days 31-60: Independent on core queue + second mechanism family, Days 61-90: Breadth, investigations, pattern-raising, Graduation: QA accuracy, calibration, written pattern memo

Days 1–30: foundations

WeekTopicsVault readingPractice
1Company products, money map, rails and reversibility; policies, privacy and access rules; insider-risk expectationsStart Here · Payment Rails Map · Customer Lifecycle Map · Glossary · Privacy and Data Use in Fraud Prevention · Insider Access ControlsDraw your company's money map from memory; tool access and navigation exercises
2Account-level enablers: ATO and fake/farmed accounts, and how they turn into transaction lossAccount Takeover (ATO) · Account Recovery Abuse · Payout Redirection · Fake Account Creation (Bots) · Multi-Accounting20 graded historical cases (ATO vs legit account changes)
3Signals: device, network, identity, behavior; what each can and can't tell youDevice Fingerprinting · IP Reputation and Proxy Detection · Account Change Events · Velocity Signals · Customer Tenure and HistorySignal interpretation drills: given a timeline, list supporting and contradicting evidence
4Your primary queue's mechanisms and SOP; case notes; decision rightsQueue-specific mechanism notes (e.g., ACH Funding Fraud, Receipt Fraud (Cashback), Refund and Return Fraud) · Case Documentation Standards · Alert Review OperationsLive decisions with 100% second review; daily feedback

Day-30 checkpoint: ≥ 50 supervised live decisions; QA accuracy trending to target; can explain the money path for their queue and its reversal windows.

Days 31–60: independence on the core queue

WeekTopicsVault readingPractice
5Controls and friction: holds, limits, step-up, payee confirmation; the cost of false positivesWithdrawal and Payout Controls · Funds Availability Holds · Risk-Based Authentication and Step-Up · Friction and Customer Experience TradeoffsDecide with sampled second review (e.g., 25–50%); value cap on independent decisions
6Scams vs unauthorized; victim handling; vulnerable customersAuthorized Push Payment (APP) Scams · Impersonation Scams · Elder Financial Exploitation · Scam Victim Indicators · Customer Education and Scam WarningsRole-play customer calls; classify 20 cases as scam vs unauthorized with facts recorded
7Regulation in practice: Reg E clocks, SAR referrals and confidentiality, network/Nacha basics, broker-dealer holds where relevantUS Regulatory Overview · Regulation E and Unauthorized Transfers · BSA-AML and SAR Filing · Nacha Rules and ACH Risk · Card Network Dispute Rules · Broker-Dealer Obligations (FINRA and SEC)Clock quiz; draft a referral from a case; tipping-off scenarios
8Second mechanism family (pick by business: payments, rewards, marketplace or brokerage)E.g., Card-Not-Present Fraud · Chargeback and Friendly Fraud · Card-Linked Offer Abuse · Buyer Protection Claim Abuse (INR and SNAD) · ACATS Transfer FraudGraded cases in the second family

Day-60 checkpoint: independent on the core queue within value limits; QA accuracy at target for two consecutive weeks; zero critical errors (e.g., missed regulatory clock, tipping off).

Days 61–90: breadth and investigation

WeekTopicsVault readingPractice
9Organized fraud: mules, rings, collusion; link analysisMoney Mules · Fraud Rings and Collusion · Entity Link Analysis · Graph AnalyticsInvestigate a synthetic ring case; produce a link chart and narrative
10Emerging threats and how adversaries adaptGenerative AI and Deepfake Fraud · Agentic Commerce Fraud · Fraud-as-a-Service Ecosystem · Threat Intelligence and Horizon ScanningRead three recent public alerts or advisories; present implications for your queue
11Metrics and labels: how decisions become dataFraud Metrics and KPIs · Fraud Labeling and Feedback Loops · Loss Taxonomy and AttributionCode 30 closed cases with mechanism, actor, initiator; compare to QA
12Industry lens and case studiesRelevant Industries Index note · Case Studies Index (e.g., Case Study - Chase Infinite Money Glitch (2024), Case Study - DraftKings Credential Stuffing (2022))Pattern memo: one page on a pattern seen in your queue, with evidence and a proposed control

Graduation (day 90): QA accuracy at or above target over 4 weeks; calibration agreement with peers at target; zero critical errors in last 30 days; pattern memo reviewed by strategy; manager sign-off. Remove value caps per policy.

Members-tier extension

Vetted members can attach the matching playbooks for operational detail (detection logic, review checklists, QA criteria), e.g., Playbook - Account Takeover Members, Playbook - Payout and Withdrawal Risk Members, Playbook - Scam Intervention Members, Playbook - Receipt and Offer Fraud Members, Playbook - ACH Funding Fraud Members, Playbook - Chargeback Management Members.

How to build it

  • Owner: ops training lead or a senior analyst with QA partnership. Strategy contributes mechanism content; compliance reviews regulatory modules.
  • Assets: a case library of historical cases with known outcomes (anonymized for training use, access-controlled) and synthetic cases for edge conditions. Refresh quarterly with new patterns.
  • Mentors: one per new analyst, with protected time.
  • Cohorts: if hiring in groups, run cohort sessions for calibration and peer learning.
  • Continuous learning after day 90: monthly pattern reviews, quarterly calibration, annual regulatory refresh.

Artifacts and templates

Onboarding tracker (per analyst)

  • Access provisioned with least privilege; acceptable-use and confidentiality acknowledged
  • Week 1–4 readings completed; quiz scores logged
  • Graded case sets: ATO, primary queue, scams, second family, ring investigation
  • Supervised decision count and QA scores by week
  • Regulatory clock and tipping-off assessments passed
  • Pattern memo submitted and reviewed
  • Graduation sign-off and authority change logged

Graded case design checklist

  • Known outcome with matured label
  • Mix of fraud, legitimate and ambiguous (so analysts learn not to over-flag)
  • Includes first-party and scam cases as well as third-party
  • Timeline, device, transaction and contact data present
  • Answer key with reasoning as well as the outcome

Metrics

  • Time to independence (days to capped and full authority)
  • QA accuracy curve by week vs cohort benchmarks
  • Critical error rate in first 90 days
  • Calibration agreement with experienced analysts
  • 90-day retention
  • Patterns raised by new analysts that led to rule or SOP changes

Pitfalls

  • Using shadowing as the whole program. People copy habits, including bad ones.
  • Teaching only the SOP. Analysts who don't understand the money path can't spot new attacks.
  • Training only on fraud cases. Analysts then over-decline, so include legitimate look-alikes.
  • Skipping regulation. Missed Reg E clocks or tipping off are expensive errors made by well-meaning new staff.
  • Having no graduation criteria, so authority creeps without evidence of readiness.
