Skill UI

This skill covers advanced techniques used in red teaming and penetration testing to elevate privileges from a low-level user to root access on a compromised Linux system. It details how to enumerate and exploit various vectors, including SUID/SGID binaries, misconfigured sudo rules, kernel vulnerabilities (e.g., Dirty Pipe), Cron job abuse, and abusing system services. Essential for comprehensive security assessments.

This expert system is designed to act as an Arch Linux specialist, diagnosing and resolving complex system issues using best practices for rolling-release distributions. It guides users through step-by-step triage plans, leveraging native tools like pacman, systemctl, and journalctl. It provides actionable, copy-paste-ready commands for remediation, verification, and cleanup, ensuring stable system recovery.

A comprehensive playbook detailing advanced techniques for post-exploitation security bypass on Linux systems. Covers escaping restricted shells (rbash), evading noexec/read-only filesystems using in-memory execution (DDexec, memfd_create), and circumventing mandatory access controls like AppArmor and SELinux. Essential for penetration testing and red team operations.

A comprehensive guide for diagnosing physical and logical network failures, such as CRC errors, packet drops, duplex mismatches, and flapping. It teaches users how to analyze interface counters and trends across routers, switches, and Linux hosts to pinpoint the root cause of connectivity issues.

Pi-hole is a powerful, network-wide DNS ad blocker solution that runs on Linux hosts (like Raspberry Pi). It automatically blocks ads, trackers, and malware domains for every device on your network without requiring browser extensions. This guide details installation via Docker or bare-metal setup, configuring it as the primary DNS server for a home network, managing blocklists, and implementing advanced features like DNS-over-HTTPS (DoH) for enhanced privacy.

A comprehensive guide to setting up a fast and secure WireGuard VPN server for remote access to your home network (homelab). Learn keypair generation, advanced Linux firewall (iptables) rules, and how to manage different tunneling modes (split vs. full tunnel) for optimal performance.

A comprehensive guide detailing the systematic workflow for analyzing malicious Linux ELF binaries. It covers essential techniques including static analysis (using readelf, elftools), dynamic tracing (strace, ltrace), and deep reverse engineering (GDB) of various threats like botnets, cryptominers, and ransomware targeting Linux environments, containers, and cloud infrastructure.
