- Reconnaissance: Enumerate cloud assets.
- Exploitation: Leverage misconfigurations and vulnerabilities.
- Post Exploitation: Establish persistence and pivot.
Why is Container and Kubernetes Security important?
Container and Kubernetes security testing identifies vulnerabilities within containerized environments and orchestration platforms. This includes assessing Docker for escape risks and Kubernetes for misconfigurations in access controls or secret management. Robust security here prevents unauthorized access and compromise of critical applications.
- Docker: Test for container escape and socket abuse.
- Kubernetes: Assess API access, RBAC, and secret extraction.
How is Thick Client and Desktop Application Testing conducted?
Thick client and desktop application testing analyzes standalone software for security vulnerabilities. This involves reverse engineering executables, analyzing network communication, and identifying local privilege escalation opportunities. The goal is to uncover weaknesses leading to unauthorized access or data manipulation on user workstations.
- Reverse Engineering Executables: Analyze compiled code.
- Network Communication Analysis: Intercept and examine traffic.
- DLL Hijacking: Exploit dynamic link library loading.
- Local Privilege Escalation through Clients: Gain higher privileges.
What does Wireless and IoT Testing entail?
Wireless and IoT testing evaluates the security of Wi-Fi networks and Internet of Things devices. This involves assessing wireless protocols for cracking vulnerabilities and analyzing IoT firmware for weaknesses. The aim is to prevent unauthorized network access, data interception, and compromise of connected devices.
- Wireless Networks: Test WPA/WPA2 cracking and evil twin attacks.
- IoT Devices: Perform firmware extraction and hardware debug analysis.
What are Active Directory and Windows Deep Attacks?
Active Directory and Windows deep attacks exploit vulnerabilities within Windows environments, especially Active Directory. This involves advanced enumeration, credential theft, and sophisticated lateral movement. The goal is to gain domain-wide control, demonstrating the impact of compromised credentials and misconfigurations on enterprise networks.
- Enumeration: Map Active Directory structure.
- Exploitation: Utilize Pass the Hash/Ticket and Golden Ticket.
- Post Exploitation: Establish persistence and perform DCSync attacks.
How is Linux Post Exploitation performed?
Linux post-exploitation involves maintaining access and escalating privileges on compromised Linux systems. This includes exploiting misconfigured cron jobs, leveraging LD_PRELOAD hijacking, and abusing NFS root squashing. These techniques deepen control and achieve persistent access within the Linux environment.
- Cron Job Abuse: Exploit scheduled tasks.
- LD_PRELOAD Hijacking: Manipulate library loading.
- NFS Root Squashing Misconfigurations: Leverage file system permissions.
- Capabilities Abuse: Exploit granular permissions.
How do attackers bypass security controls?
Bypassing security controls involves techniques to circumvent defensive measures like WAF, RASP, and AV/EDR systems. Attackers employ various methods to evade detection and execute malicious payloads. This highlights the need for multi-layered and adaptive security strategies to protect systems effectively.
- WAF Bypass: Circumvent web application firewalls.
- RASP Bypass: Evade runtime application self-protection.
- AV EDR Evasion: Avoid detection by security solutions.
- Sandbox Evasion: Escape virtualized analysis environments.
What is Red Team and Adversary Simulation?
Red Team and Adversary Simulation exercises mimic real-world threat actors to test an organization's defensive capabilities. These engagements cover the entire attack lifecycle, from initial access and command-and-control to data exfiltration. The goal is to identify gaps in detection and response, improving overall security resilience.
- Initial Access: Gain initial entry.
- C2 and Persistence: Establish command and control.
- Data Exfiltration: Steal sensitive data.
- OPSEC and Detection Avoidance: Operate stealthily.
What are common Defensive Evasion Techniques?
Defensive evasion techniques are methods attackers use to avoid detection by security systems.

Frequently Asked Questions
What is VAPT?
VAPT combines vulnerability assessments to identify weaknesses and penetration testing to exploit them, providing a comprehensive view of an organization's security posture. It helps proactively defend against cyber threats.
What is the difference between passive and active reconnaissance?
Passive reconnaissance gathers information without direct interaction with the target, like OSINT. Active reconnaissance involves direct engagement, such as port scanning, which may be detectable by the target.
Why is post-exploitation important in VAPT?
Post-exploitation demonstrates the potential impact of a breach by showing how an attacker can escalate privileges, move laterally, and exfiltrate data after initial access, revealing deeper risks.
What are common web application vulnerabilities?
Common web application vulnerabilities include SQL Injection, Broken Access Control (IDOR), Cross-Site Scripting (XSS), and Server-Side Request Forgery (SSRF), often listed in the OWASP Top 10.
How does cloud penetration testing differ from traditional network testing?
Cloud penetration testing focuses on cloud-specific misconfigurations, IAM issues, and service vulnerabilities unique to platforms like AWS, Azure, and GCP, rather than solely on on-premise network infrastructure.
