Offensive Security

Pentesting & Blackbox Testing

Breaking systems ethically to make them stronger. A detailed look at my offensive security methodology, specializations and the tooling I rely on across web, network and cloud assessments.

Specializations

Areas of expertise

🎯

Penetration Testing

Goal-oriented, real-world attack simulation against applications, APIs, networks and cloud workloads to prove exploitability and business impact — not just theoretical risk.

📦

Blackbox Testing

Zero-knowledge assessment from an external attacker's perspective. Reconnaissance, attack-surface mapping, input fuzzing and control validation with no internal access or source code.

⚪

Greybox & Whitebox

Credentialed and source-assisted reviews to dig deeper into authorization logic, business-logic flaws and configuration weaknesses that blackbox alone cannot surface.

🌐

Web Application Security

OWASP Top 10 coverage — injection, broken access control, authentication flaws, SSRF, XSS, insecure deserialization and misconfigurations across modern web stacks.

🔌

Network & Infrastructure

Port and service enumeration, vulnerability validation, privilege escalation and lateral-movement analysis across internal and external network perimeters.

☁️

Cloud Security Testing

AWS & Azure configuration review, IAM policy analysis, exposed-asset discovery and workload hardening aligned to cloud security best practices.

How I Work

Penetration testing methodology

A structured, repeatable process aligned with industry standards (PTES, OWASP, NIST) to deliver consistent, high-signal results.

01 · Reconnaissance & Scoping

Define rules of engagement, gather OSINT, enumerate the attack surface and map in-scope assets. In blackbox engagements this is done with no prior internal knowledge.

02 · Scanning & Enumeration

Active and passive discovery of hosts, services, technologies and entry points. Fingerprinting versions and identifying potential weak points.

03 · Vulnerability Assessment

Identify and prioritize vulnerabilities through automated scanning combined with manual verification to eliminate false positives.

04 · Exploitation

Safely exploit confirmed vulnerabilities to demonstrate real impact — access gained, data exposed or controls bypassed.

05 · Post-Exploitation & Privilege Escalation

Assess the depth of a compromise: lateral movement, privilege escalation and the blast radius of a successful attack.

06 · Reporting & Remediation

Deliverable

Clear, prioritized findings with reproduction steps, risk ratings and actionable remediation guidance — plus re-testing to confirm fixes.

Deep Dive

Blackbox vs. Greybox vs. Whitebox

Choosing the right testing depth depends on your goals, timeline and threat model.

BLACKBOX

Outsider's view

No internal knowledge, credentials or source code. Mimics a real external attacker to reveal what's exploitable from the internet. Fast attack-surface validation.

GREYBOX

Partial knowledge

Limited access such as standard user credentials. Efficiently targets authenticated flows, authorization and business-logic flaws with realistic insider context.

WHITEBOX

Full transparency

Complete access to architecture and source. Deepest coverage — uncovering subtle logic flaws, insecure configurations and hard-to-reach vulnerabilities.
