Most Common Threats in E-commerce
Online stores are targeted by thousands of automated and manual attacks every day. We help detect and fix vulnerabilities before cybercriminals can exploit them.
Customer Data Breaches
E-commerce systems process data from hundreds of thousands of customers. SQL Injection, Broken Access Control, and Insecure Direct Object Reference can lead to massive leaks of personal data, addresses, and order history. GDPR fines up to EUR 20 million.
Business Logic Flaws and Fraud
Price manipulation, reuse of discount coupons, race conditions in payments, bypassing order limits. Business Logic Flaws are the most costly vulnerabilities in e-commerce — averaging 50-200k in monthly losses.
Payment Gateway Vulnerabilities
Improper implementation of PayU, Przelewy24, Stripe, or PayPal can allow payment interception, replay attacks, amount manipulation, or payment bypass. We test compliance with provider documentation and PCI-DSS.
User Account Takeover
Credential stuffing, brute force, session hijacking, CSRF, XSS, and weak password reset mechanisms allow attackers to take over customer accounts. They gain access to order history, saved payment cards, and loyalty programs.
Insecure Plugins and Integrations
WooCommerce plugins, PrestaShop modules, and Magento extensions often contain critical CVE vulnerabilities. Integrations with ERP, WMS, couriers, Google Analytics, and Facebook Pixel are additional attack vectors (supply chain, JS skimming).
Poorly Secured Admin Panels
The admin panel is the key to the entire store. Missing 2FA, weak passwords, internet accessibility without IP whitelisting, lack of login rate limiting, and unpatched CMS vulnerabilities lead to full store takeover by attackers.

FAQ – Penetration Testing for E-commerce
Answers to the most common questions from online stores about penetration testing and security audits.
Why does an online store need penetration testing?
Online stores process customers’ personal data, payment card information, and handle financial transactions. A data breach leads to loss of customer trust, GDPR fines (up to EUR 20 million), chargeback liability, and reputational damage. Penetration testing detects vulnerabilities before cybercriminals can exploit them.
Is penetration testing required by PCI-DSS?
Yes. PCI-DSS Requirement 11.3 mandates penetration testing at least once a year and after every significant change to the infrastructure or application handling payment card data. Tests must cover both the network and application layers.
Which e-commerce platforms do you test?
We test all major platforms: Magento (Adobe Commerce), WooCommerce, PrestaShop, Shopify, Shoper, IdoSell, Wix, BigCommerce and custom e-commerce solutions built on Laravel, Symfony, Django, or Node.js. We have experience testing both standard installations and heavily customized versions.
How long does a penetration test of an online store take?
The duration depends on the store’s size: small WooCommerce/PrestaShop store (3-5 days), mid-sized store with customizations (5-8 days), large Magento platform/marketplace (10-15 days), store plus mobile app (7-12 days). For stores with integrations (ERP, WMS, couriers) the timeline may extend by 2-4 days.
Can testing be performed on the production environment?
Yes, we typically test the production environment during low-traffic hours (e.g., nighttime, early morning) using techniques that are safe for store operations. We avoid DoS tests and actions that could affect availability. Alternatively, we can test a staging/dev environment if it is identical to production.
What do you test in an online store?
We test: authorization and authentication, payment processes and gateway integrations, shopping cart and checkout flow, admin panel, discount and promotion mechanisms, APIs (REST/GraphQL), third-party plugins and modules, anti-fraud mechanisms, OWASP Top 10, business logic flaws (price manipulation, payment bypass).
Do you test payment gateway integrations?
Yes. We test integrations with: PayU, Przelewy24, Stripe, PayPal, Dotpay, Tpay, Paynow, Adyen, Klarna. We verify the correctness of payment protocol implementation, protection against replay attacks, signature validation, callback handling, and compliance with provider documentation.
Do you help with achieving PCI-DSS compliance?
Yes. We offer PCI-DSS compliance audits covering all 12 requirements of the standard. We deliver detailed reports compliant with QSA (Qualified Security Assessor) requirements, identify areas of non-compliance, and advise on remediation. We can also help prepare for PCI-DSS certification.
Do you test for fraud and scam vulnerabilities?
Yes. We specialize in detecting business logic flaws such as: product price manipulation, reuse of discount codes, order limit bypass, loyalty program abuse, race conditions in payments, and cart amount manipulation. These are often the most costly vulnerabilities for e-commerce.
What does a penetration test report include?
The report includes: executive summary for management, detailed description of vulnerabilities with CVSS risk ratings, proof-of-concept (screenshots, HTTP requests), step-by-step remediation recommendations, mapping to OWASP Top 10 and PCI-DSS, prioritization of fixes, and testing timeline. Format: PDF plus optionally Excel with a vulnerability list for tracking in JIRA/Redmine.
