Training Course on Web Shell Detection and Analysis

Training Course on Web Shell Detection and Analysis

Introduction

In today's evolving threat landscape, web shells have emerged as one of the most insidious tools used by cybercriminals to exploit vulnerable web applications. These malicious scripts provide persistent backdoor access to compromised servers, enabling unauthorized remote control, data exfiltration, lateral movement, and stealthy attacks. As digital infrastructure expands, web shell detection and analysis have become a critical skillset for cybersecurity professionals, penetration testers, SOC analysts, and incident responders. Training Course on Web Shell Detection and Analysis provides comprehensive, hands-on knowledge required to identify, analyze, and mitigate these hidden threats using advanced tools and real-world techniques.

This instructor-led and lab-intensive course covers everything from code obfuscation patterns and command-and-control behavior to machine learning detection models and YARA-based threat hunting. Participants will develop an in-depth understanding of how attackers deploy web shells across various platforms such as PHP, ASP, JSP, and Python environments. By the end of the training, learners will be able to proactively hunt for and neutralize web shells, understand attacker TTPs (Tactics, Techniques, and Procedures), and integrate detection mechanisms into SIEMs, EDR, and cloud security solutions.

Course Objectives

1. Understand web shell fundamentals and attack vectors
2. Identify commonly exploited web vulnerabilities leading to web shell deployment
3. Detect obfuscated malicious code in web environments
4. Analyze live and dormant web shell behavior using forensic techniques
5. Develop and deploy YARA rules for web shell detection
6. Use machine learning models for anomaly-based detection
7. Integrate web shell detection into SIEM and XDR systems
8. Perform memory and disk forensics to trace web shell activities
9. Conduct threat hunting using open-source intelligence (OSINT)
10. Automate web shell analysis using Python and custom scripts
11. Respond to web shell incidents using IR playbooks
12. Assess server hardening and mitigation best practices
13. Evaluate cloud-hosted application security against web shell threats
