Key Responsibilities and Required Skills for Infiltration Technician

🎯 Role Definition

An Infiltration Technician is a highly specialized offensive security professional who acts as an ethical hacker to strengthen an organization's defenses. Functioning as a sparring partner for the defensive security team, this individual proactively identifies, exploits, and helps remediate vulnerabilities before malicious actors can. They simulate real-world cyberattacks across networks, applications, and human elements to provide a realistic assessment of security posture. The core purpose of this role is not just to find flaws, but to provide actionable intelligence and context that enables the organization to build a more resilient and robust security program. They are the critical thinkers and creative problem-solvers who test the limits of technology and process to ensure the fortress is secure.

Core Responsibilities

Primary Functions

Plan and execute comprehensive penetration tests on web applications, mobile applications, and APIs, meticulously documenting exploit chains according to frameworks like OWASP.
Conduct in-depth network penetration testing on both internal and external infrastructures, including cloud environments (AWS, Azure, GCP), to identify misconfigurations and pathways for lateral movement.
Perform rigorous vulnerability assessments using a combination of automated scanning tools and manual verification to eliminate false positives and prioritize genuine threats.
Develop and launch sophisticated social engineering campaigns, including phishing and vishing, to test the effectiveness of security awareness training and incident response procedures.
Simulate the Tactics, Techniques, and Procedures (TTPs) of known Advanced Persistent Threats (APTs) in full-scope Red Team engagements to test detection and response capabilities.
Analyze and reverse engineer malware samples or suspicious binaries to understand their functionality, indicators of compromise, and potential impact on the organization.
Perform physical security assessments of corporate facilities, attempting to bypass physical controls like locks, sensors, and access card systems to identify weaknesses.
Author detailed, high-quality engagement reports that clearly articulate identified vulnerabilities, potential business impact, and pragmatic, step-by-step recommendations for remediation.
Develop custom scripts, tools, and exploits to automate testing processes and bypass unique or complex security controls that off-the-shelf tools cannot handle.
Conduct thorough security source code reviews to identify vulnerabilities like injection flaws, insecure cryptographic storage, and logic errors early in the development lifecycle.
Lead purple team exercises, working collaboratively with Blue Team (defensive) analysts to test, validate, and improve detection and response playbooks in real-time.
Assess the security of wireless networks by attempting to crack encryption, exploit rogue access points, and intercept sensitive data in transit.
Evaluate the security posture of operational technology (OT) and Industrial Control Systems (ICS) environments, understanding the unique risks and protocols involved.
Safely exploit vulnerabilities in Active Directory environments to demonstrate the impact of misconfigurations, weak permissions, and credential theft.

Secondary Functions

Present findings, attack paths, and strategic recommendations to both technical engineering teams and senior business leadership to drive security improvements.
Maintain and contribute to a curated knowledge base of adversary TTPs, attack vectors, and remediation strategies for internal team use.
Provide expert security consultation to development and infrastructure teams throughout the system development lifecycle to embed security from the start.
Mentor junior security analysts and technicians, sharing knowledge of offensive security tools, methodologies, and the attacker mindset.
Research emerging security threats, zero-day vulnerabilities, and innovative attack techniques to ensure testing methodologies remain current and effective.
Support ad-hoc data requests and exploratory data analysis to uncover hidden security trends.
Contribute to the organization's data strategy and roadmap, particularly around security metrics and threat intelligence.
Collaborate with business units to translate data needs into engineering requirements for security tooling.
Participate in sprint planning and agile ceremonies within the data engineering team and security department.

Required Skills & Competencies

Hard Skills (Technical)

Penetration Testing Toolkits: Deep proficiency with industry-standard tools such as Metasploit, Burp Suite Pro, Cobalt Strike, Nmap, and Wireshark.
