Skill UI

Provides comprehensive methodologies for planning, executing, and validating complex, zero-downtime system migrations. This skill covers critical patterns across data (Schema Evolution, CDC), services (Strangler Fig, Canary), and infrastructure (On-Prem to Cloud). It ensures minimal business impact, data consistency, and reliable rollback strategies.

This skill acts as an SLO (Service Level Objective) expert, specializing in implementing reliability standards and error budget-based engineering practices. It guides the design of comprehensive SLO frameworks, establishment of meaningful SLIs, and creation of monitoring systems. Use this to balance product feature velocity with required service reliability, ensuring all engineering decisions are data-driven and aligned with business objectives.

This skill provides a comprehensive methodology for simulating privilege escalation attacks on compromised Linux and Windows environments. It guides the user through identifying vectors—including SUID abuse, misconfigured services, kernel vulnerabilities, cron job exploitation, and credential harvesting—to elevate initial low-privilege access to root or SYSTEM control. It is crucial for deep-dive penetration testing and assessing system security hardening.

This guide details advanced techniques used in red teaming and penetration testing to elevate user privileges from a low-level account to root access on a compromised Linux system. It covers exploiting misconfigurations, vulnerable services (like SUID/SGID binaries), improper sudo rules, kernel vulnerabilities (e.g., Dirty Pipe), and abuse of system services like Cron jobs and Systemd. Essential for authorized security assessments.
