Region

Scope

Storefront, checkout, customer + seller APIs, admin console, mobile apps, payment and logistics integrations

The Challenge

What the team was up against

Challenge 01

Magecart-style skimming risk on checkout pages

Storefront loaded 30+ third-party marketing and analytics scripts on the checkout route, creating a wide supply-chain surface for client-side card skimmers and failing PCI DSS 4.0 requirements 6.4.3 and 11.6.1.

Challenge 02

Account takeover exposure across web and mobile

Customer login lacked rate limiting, used SMS OTP without device binding, and shared session tokens between web and mobile, enabling credential stuffing and OTP relay attacks at festive-sale scale.

Challenge 03

IDOR and privilege drift in seller admin console

Multi-tenant seller console exposed numeric order, refund and payout IDs without object-level authorization, while RBAC had drifted across 40+ internal roles, risking cross-merchant data exposure under DPDP.

Our Approach

How we solved it

Step 01

PCI DSS 4.0 aligned checkout and CSP hardening

Mapped every script on PAN-handling pages, enforced a strict Content-Security-Policy with SRI, and validated client-side change detection against PCI DSS 4.0 req 6.4.3, 11.6.1 using Burp Suite Pro and custom DOM-tamper probes.

Step 02

ATO red team simulating festive-sale attacker traffic

Ran a CERT-In-aligned ATO simulation using credential stuffing replay, SIM-swap OTP relay, and proxy-rotated traffic against login, guest-checkout and wallet endpoints, evaluated against OWASP ASVS 4.0 V2 and V3 controls.

Step 03

Authorization matrix audit of seller admin APIs

Built a per-role authorization matrix for 40+ seller and ops roles, then fuzzed every order, refund, payout and report API for IDOR, BOLA and BFLA using a custom Postman + Burp Autorize harness.

The Results

What changed after the engagement

Vulnerabilities surfaced across stack

Including 4 critical IDORs in seller payout APIs, 2 high-risk skimming vectors on checkout, and 11 ATO-class issues across web and mobile login.

100%

Remediation verified before peak sale

Every critical and high finding retested and closed three weeks before the festive sale window, with CERT-In safe-to-host letter issued for the merchant domain.

Card-skimming or ATO incidents in 18 months

Post-engagement monitoring across two festive sale cycles recorded zero confirmed Magecart, ATO or seller-data-exposure incidents on the hardened platform.
