Overview

In an era where software underpins every business operation, hidden vulnerabilities in source code—from insecure third-party libraries to flawed business logic—can silently expose organizations to data breaches, supply chain attacks, and regulatory penalties. Many teams rely solely on automated SAST tools or assume “shift-left” DevOps pipelines catch all risks, overlooking critical issues like hardcoded secrets, race conditions, and access control bypasses. Our Source Code Review combines manual expertise with advanced analysis to dissect your codebase line-by-line, exposing vulnerabilities that automated scanners miss and transforming your SDLC into a security-first pipeline.

What is Source Code Review?

Source Code Review is a meticulous, human-driven examination of your application’s codebase to identify security flaws, anti-patterns, and compliance gaps. Our certified code auditors analyze programming logic, data flows, and dependencies across repositories—spanning custom code, third-party libraries, and CI/CD configurations—to uncover risks like insecure API integrations, cryptographic weaknesses, and logic flaws that automated tools cannot contextualize.

Key Focus Areas

We prioritize vulnerabilities aligned with OWASP Top 10, CWE Top 25, and language-specific risks, including:

✅ Injection Vulnerabilities (SQLi, OS command, template engines)
✅ Insecure Authentication/Authorization (JWT mishandling, broken access control checks)
✅ Cryptographic Failures (Weak hashing algorithms, hardcoded keys, improper IV usage)
✅ Business Logic Flaws (Race conditions, payment bypasses, workflow manipulation)
✅ Unsafe Memory Management (Buffer overflows, use-after-free in C/C++/Rust)
✅ Third-Party Risks (Vulnerable dependencies via npm, PyPI, or NuGet)
✅ Hardcoded Secrets (API keys, passwords, tokens in plaintext)
✅ Insecure Deserialization (Java/Python/.NET object exploitation)
✅ Input Validation Gaps (XSS, SSRF, path traversal vectors)
✅ CI/CD Pipeline Misconfigurations (Exposed build secrets, insecure Jenkinsfiles)

How We Execute Source Code Review

Our hybrid manual/automated approach ensures depth and accuracy:

1. Pre-Engagement Scoping

   • Define target repositories, branches, and languages (e.g., Java, Python, Go, Solidity).

2. SAST Tooling Baseline

   • Run industry-leading tools (Checkmarx, Semgrep, CodeQL) to flag common vulnerabilities.

3. Manual Line-by-Line Analysis

   • Audit critical modules (auth, payment, data processing) for logic flaws and anti-patterns.

4. Data Flow Tracing

   • Map user input from entry points (APIs, forms) to sensitive sinks (DB queries, OS calls).

5. Business Logic Testing

   • Identify loopholes in workflows (e.g., “add to cart” logic, coupon code abuse).

6. Third-Party Dependency Audits

   • Pinpoint vulnerable libraries using OWASP Dependency-Check and Snyk.

7. Secrets Detection

   • Scan for exposed credentials using GitLeaks, TruffleHog, and custom regex patterns.

8. Compliance Checks

   • Validate against PCI DSS 6.3.2, HIPAA §164.312, and GDPR Article 32.

9. Exploitability Assessment

   • Rank findings by real-world impact (e.g., PoC for remote code execution).

10. Remediation & Retesting

    • Provide secure code snippets, dependency upgrade paths, and post-fix validation.
