Securing Your E-commerce APIs: Preventing insecure memory deallocation leading to information disclosure in C Implementations

Understanding the Vulnerability: Insecure Memory Deallocation and Information Disclosure In C-based e-commerce API implementations, a common yet insidious vulnerability arises from insecure memory deallocation. This often manifests as a use-after-free (UAF) bug, where a program attempts to access memory that has already been freed. If this freed memory is subsequently reallocated and populated with sensitive […]

How We Audited a High-Traffic Shopify Enterprise Stack on OVH and Mitigated Cross-Site Scripting (XSS) in custom themes

Understanding the Threat Landscape: XSS in Enterprise E-commerce High-traffic Shopify enterprise stacks, especially those heavily customized with bespoke themes and third-party applications, present a complex attack surface. While Shopify’s core platform offers robust security, custom code, particularly within themes, can introduce vulnerabilities. Cross-Site Scripting (XSS) remains a persistent threat, capable of stealing session cookies, defacing […]

Top 5 ModSecurity Exceptions and Security Auditing Plugins for Apache to Double User Engagement and Session Duration

Tuning ModSecurity: Essential Exceptions for E-commerce Stability While ModSecurity is a powerful Web Application Firewall (WAF) for Apache, its default rulesets can sometimes be overly aggressive, leading to legitimate user actions being blocked. This is particularly detrimental in e-commerce environments where user experience directly impacts conversion rates and session duration. Instead of disabling ModSecurity entirely, […]

Mitigating OWASP Top 10 Risks: Finding and Patching Cross-Site Scripting (XSS) in custom themes in WordPress

Identifying XSS Vulnerabilities in WordPress Custom Themes Cross-Site Scripting (XSS) remains a persistent threat, and custom WordPress themes, often developed without rigorous security scrutiny, are prime targets. These vulnerabilities arise when user-supplied data is not properly sanitized or escaped before being rendered in the browser, allowing attackers to inject malicious scripts. Our approach to mitigating […]

How We Audited a High-Traffic WordPress Enterprise Stack on DigitalOcean and Mitigated Remote Code Execution (RCE) via insecure file uploads

Initial Reconnaissance and Attack Vector Identification Our engagement began with a deep dive into the existing WordPress enterprise stack hosted on DigitalOcean. The primary concern was a recent uptick in suspicious outbound traffic and intermittent performance degradation, hinting at a potential compromise.
