Retail & E-Commerce
Protecting every transaction and every customer.
Retail and e-commerce face a unique intersection of threats: financially motivated attacks on payment data, loyalty programme fraud, and brand-damaging web skimming campaigns that silently steal customer card details at scale. The pace of digital commerce — seasonal traffic spikes, rapid new feature deployment, third-party integrations — creates a constantly expanding attack surface that security rarely keeps pace with.
Threat landscape
Web Skimming (Magecart) Attacks
JavaScript-based payment skimmers injected into e-commerce platforms steal cardholder data at the point of entry — invisible to the shopper and undetected by server-side security controls. Magecart and its successors have compromised thousands of retail sites, often persisting for months before discovery.
Account Takeover & Loyalty Fraud
Credential stuffing attacks against customer login portals use breached password databases to compromise loyalty programme accounts at scale. Fraudsters monetise these accounts by redeeming points, reselling gift cards, and using stored payment methods for unauthorised purchases.
PCI-DSS Scope & Cardholder Data Exposure
Retail organisations frequently underestimate their PCI-DSS scope — discovering that third-party integrations, logging systems, and analytics platforms have inadvertently captured cardholder data. Scope creep creates compliance and breach risk simultaneously.
Seasonal Infrastructure Blind Spots
Rapid infrastructure scaling for peak retail periods (Black Friday, Diwali, Christmas) introduces new systems that lack hardening, skip security review processes, and are frequently left running beyond the peak period with reduced monitoring attention.
Supply Chain & Third-Party Integration Attacks
Retail platforms integrate dozens of third-party services: payment processors, analytics, recommendation engines, chat widgets. Each integration represents a potential supply chain attack vector — malicious code injected via a third-party script can compromise every visitor to your site.
Compliance & regulations
Mandatory for all merchants processing card payments. Level 1 merchants require annual penetration testing by a QSA-assessed firm and quarterly network scans.
Applies to all customer personal data processed by Indian retailers, including purchase history, loyalty data, and browsing behaviour — with consent, purpose limitation, and breach notification requirements.
Applies to any Indian retailer processing data of EU customers. Requires data protection by design, breach notification within 72 hours, and respects data subject rights.
Increasingly required by enterprise retail clients and payment processors as a condition of supplier onboarding and API integration agreements.

Sample engagement
Anonymised case study — Confidential — Online fashion retailer, 500,000+ customers
Challenge
The retailer's QSA identified a gap in their annual PCI-DSS penetration testing requirement. Additionally, a recent platform migration had introduced new third-party integrations that hadn't been security reviewed, and marketing were pushing to expand the loyalty programme API to mobile.
Approach
UnlockSec delivered a combined Application Security and API Security assessment. The application assessment included a specific focus on third-party script inventory and CSP header analysis to detect Magecart risk. The loyalty API assessment tested BOLA, excessive data exposure, and rate limiting against credential stuffing.
Outcome
A critical finding identified that a third-party product recommendation widget had unnecessary access to session tokens — a potential Magecart attack vector. Two High findings in the loyalty API allowed horizontal privilege escalation between customer accounts. The engagement report satisfied the PCI-DSS penetration testing requirement. All findings remediated before the mobile loyalty launch.
