Muskan Sureka

I’m a Senior Fraud Analyst with 5+ years across fintech startups and large-scale e-commerce, specializing in transaction fraud, card program risk, and fraud rule implementation. I thrive in fast-paced, remote-first environments—building forensic fraud cases from raw data and driving systemic fixes under pressure.

At Neu Money, I uncovered a card number predictability vulnerability using statistical analysis, producing evidence that led to a processor-level internal security review. I’ve investigated bust-out fraud involving returned payments, designed and implemented 10+ processor-level fraud control rules (including CNP merchant category blocks and BNPL platform restrictions), and removed a misconfigured rule responsible for ~60% of false-positive card declines. I’ve also escalated systemic rule failures backed by full account-level evidence and secured engineering root-cause investigations.

Before that, at Amazon, I investigated account takeovers and payment abuse at scale, partnering with engineering to improve detection accuracy by 30% while reducing manual review volume by 25%. I developed fraud prevention SOPs, trained 25+ analysts, and earned Investigator of the Quarter (Q4 2024) for automation and chargeback optimization work—plus I previously led KYC/AML reviews and risk dashboarding at a financial services firm, cutting turnaround time by 20%.
