// The Case for Testing

Your application is your attack surface.

Web applications are the most targeted entry point for attackers. Complex authentication flows, business logic, third-party integrations, and API backends create a vast attack surface that automated scanners miss. HackLabs' senior testers combine the latest tooling with deep manual analysis to identify vulnerabilities that matter — the ones that lead to data exposure, account compromise, and business logic abuse.

// Deep Manual Testing

Beyond automated scanning

We systematically test authentication, session management, access controls, business logic, and data handling — finding what scanners miss.

// OWASP Aligned

Comprehensive coverage

Testing covers OWASP Top 10, OWASP ASVS, and custom attack scenarios tailored to your application's functionality and threat model.

// Developer-Friendly Reporting

Built for remediation

Findings include proof-of-concept payloads, CVSS scores, CWE mappings, and step-by-step remediation guidance your development team can act on immediately.

// What We Cover
  • Authentication and session management flaws
  • Injection vulnerabilities (SQL, XSS, XXE, SSTI, SSRF)
  • Broken access control and privilege escalation
  • Business logic and workflow abuse
  • File upload and path traversal vulnerabilities
  • Insecure direct object references (IDOR)
  • Security misconfigurations and information disclosure
  • Third-party component and dependency analysis
  • OWASP Top 10 and ASVS coverage
  • API endpoints embedded in web applications
// Capabilities

What we test

Authentication & Session Management

Testing of login flows, password reset mechanisms, MFA bypass attempts, session token entropy, and cookie security attributes.

Injection Attacks

SQL injection (blind, error-based, time-based), XSS (stored, reflected, DOM), XXE, SSTI, SSRF, and command injection testing.

Access Control Testing

Horizontal and vertical privilege escalation, IDOR vulnerabilities, role bypass, and forced browsing against protected resources.

Business Logic Testing

Application-specific logic flaws including price manipulation, workflow bypass, race conditions, and function-level abuse.

Configuration & Disclosure

HTTP security headers, TLS configuration, error message disclosure, directory listings, and exposed sensitive endpoints.

Client-Side Security

DOM-based XSS, client-side storage abuse, postMessage vulnerabilities, CORS misconfiguration, and Subresource Integrity.

// Methodology

Our testing process

01

Scoping

We define the engagement boundaries, objectives, and rules of engagement. Clear scope means focused testing and accurate results.

02

Testing

Senior consultants conduct both automated and manual testing, replicating real-world attack techniques against your environment.

03

Reporting

Detailed technical findings with risk ratings, proof-of-concept evidence, and clear remediation guidance for both technical and executive audiences.

04

Remediation Support

We stay engaged beyond the report. Our team answers remediation questions and offers a complimentary re-test on critical findings.
