This skill provides a comprehensive method for detecting kernel-level rootkits on Linux systems. It leverages memory forensics using Volatility3 on physical memory dumps, combined with cross-view analysis (comparing /proc vs /sys) and live system scanning (rkhunter). Techniques include identifying hooked syscall tables, discovering hidden kernel modules, and detecting tampered system structures.

Comprehensive digital forensic analysis guide for Linux systems. It covers the collection and examination of critical artifacts such as authentication logs, shell histories, user configurations, system files (passwd, shadow), and persistence mechanisms to effectively detect security compromises, unauthorized access, and malicious activity.

This skill outlines the comprehensive process of memory forensics on compromised Linux systems. It guides users through acquiring volatile memory using the LiME kernel module and analyzing the resulting image with the Volatility 3 framework. Key artifacts extracted include process lists, network connections, bash history, and loaded kernel modules, making it an essential technique for incident response, threat hunting, and security investigations.

A comprehensive skill for cybersecurity threat hunting and incident response. This tool systematically scans Linux systems to detect various persistence vectors used by adversaries, including suspicious crontab entries, unauthorized systemd units, LD_PRELOAD hijacking, profile modifications (.bashrc), and SSH key backdoors. It correlates findings with auditd logs to build a detailed timeline of compromise.

A comprehensive guide for deploying and configuring CrowdStrike Falcon EDR agents across diverse endpoints (Windows, macOS, Linux). This skill covers silent installation via SCCM, Intune, GPO, and command-line methods, alongside establishing robust prevention and response policies. Ideal for onboarding endpoints, enhancing threat detection capabilities, and integrating Falcon telemetry into SIEM platforms for advanced security operations.

A comprehensive guide to deploying and configuring osquery across diverse endpoints (Windows, macOS, Linux). This tool allows security teams to gather deep, SQL-based insights into endpoint state, including running processes, network connections, system configuration, and installed software. It is essential for threat hunting, compliance auditing, and building centralized fleet visibility.

This skill provides advanced runtime security rules using Falco, a CNCF-graduated tool. It monitors Linux syscalls to detect container escape attempts in real-time, identifying techniques such as mounting host filesystems, unauthorized namespace access (nsenter), and privileged container launches. It is crucial for SOC analysts and security teams enhancing cloud-native security coverage.

A guide for security professionals and threat hunters to proactively detect advanced privilege escalation techniques across Windows and Linux environments. It covers critical attack methods including token manipulation, UAC bypass, unquoted service paths, and kernel exploits, utilizing EDR and SIEM data sources for comprehensive incident response and security assessments.

This skill addresses advanced threat detection for critical infrastructure (OT/ICS). It monitors sophisticated, multi-stage cyber-physical attacks, focusing specifically on PLC logic integrity monitoring, detecting unauthorized modifications, and analyzing process anomalies. It covers the entire attack chain, from initial USB-borne access (IT) to process manipulation (OT).

A comprehensive guide for threat hunting designed to detect various forms of privilege escalation abuse, including UAC bypass, setuid/setgid manipulation, and exploiting auto-elevating processes on Windows and Linux. It provides specific monitoring workflows, detection queries (Splunk, KQL, Sigma), and key indicators related to MITRE ATT&CK T1548.

The Metasploit Framework is the industry standard platform for penetration testing and vulnerability validation. It provides numerous modules (exploits, payloads, auxiliaries) used to confirm if identified security weaknesses are genuinely exploitable. This guide details using Metasploit in a structured, risk-based workflow for authorized testing, including vulnerability checking, post-exploitation assessment, and patch verification.

This skill automates the hardening of Linux endpoints (Ubuntu, RHEL, CentOS) by implementing industry-standard security best practices guided by CIS Benchmarks. It systematically secures various layers, including filesystem permissions, network parameters (sysctl), SSH configuration, user access controls (PAM), and integrates deep auditing using auditd and OpenSCAP. It is essential for achieving compliance with standards like PCI DSS, HIPAA, and SOC 2.
