Skill UI

Expert in developing complete, high-performance firmware and peripheral drivers for ARM Cortex-M platforms (STM32, Teensy, nRF52). Specializes in low-level hardware interaction, including implementing drivers for I²C, SPI, UART, and managing complex concurrency patterns using FreeRTOS/Zephyr. Provides critical guidance on optimizing for determinism, cache coherency, DMA transfers, and memory barriers to ensure reliable embedded system operation.

A comprehensive guide detailing the entire workflow for analyzing embedded firmware. It covers hardware-level extraction methods (UART, JTAG, SPI dump), filesystem analysis (SquashFS, JFFS2), binary reverse engineering using tools like Ghidra, and identifying common vulnerabilities (Buffer Overflow, Command Injection). Ideal for security researchers and embedded systems engineers.

This skill guides the comprehensive evaluation and selection of Threat Intelligence Platforms (TIPs). It assesses vendor capabilities, including STIX/TAXII support, workflow automation, SIEM/SOAR integration, and total cost of ownership. It is essential for procurement decisions, migrating between TIP solutions, or assessing whether the current CTI program meets required maturity levels.

This skill guides the design and implementation of security zones and conduits for Industrial Automation and Control Systems (IACS) following IEC 62443-3-2 standards. It covers risk-based zone partitioning, defining security levels (SL-T), deploying microsegmentation using industrial firewalls, and validating the architecture against the Purdue Model.

Pod Security Admission (PSA) is a built-in Kubernetes admission controller designed to enforce Pod Security Standards (Baseline, Restricted, Privileged) at the namespace level. It serves as a crucial replacement for the deprecated PodSecurityPolicy (PSP), allowing users to implement robust security controls and maintain compliance. By applying specific labels, administrators can set enforcement modes (enforce, audit, warn) to harden container environments against unauthorized privilege escalation and security risks.

This tool implements network segmentation based on the Purdue Enterprise Reference Architecture (PERA). It helps secure Industrial Control Systems (ICS) by mapping assets and data flows to specific Purdue levels (0-5), defining necessary firewall rules, and establishing DMZs. It ensures strict traffic control between IT and OT domains, adhering to standards like IEC 62443 and facilitating secure network retrofitting.

This skill provides a comprehensive framework for performing privilege escalation assessments post-initial compromise. It guides testers in identifying paths from low-privilege access to root or SYSTEM-level control on both Linux and Windows operating systems. Techniques covered include abusing SUID binaries, exploiting misconfigured services, leveraging kernel vulnerabilities, and harvesting credentials.

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.

A deep dive into advanced malware reverse engineering techniques. Learn how to utilize Ghidra's powerful disassembler and decompiler to analyze complex malware binaries. This guide covers identifying C2 communication protocols, extracting cryptographic routines, understanding memory injection, and analyzing low-level assembly code for core logic and evasion techniques. Essential for professional cybersecurity analysts.

A comprehensive guide for systematically assessing REST and GraphQL API endpoints against the OWASP API Security Top 10 risks. This includes practical workflows for testing critical vulnerabilities such as Broken Object Level Authorization (BOLA), broken authentication, excessive data exposure, and rate limiting, using tools like Burp Suite, Postman, and ffuf. Ideal for pre-deployment audits and authorized penetration testing engagements.

This skill analyzes accumulated usage logs from a complex research harness (ARIS) to propose structural optimizations. It identifies areas for improvement in SKILL scripts, default parameters, workflow ordering, and reviewer prompts. It is designed to automate the meta-level engineering process, ensuring that system efficiency is continuously improved based on real-world usage data.

Provides comprehensive, enterprise-level monitoring for all Power Automate flows across an entire tenant. Using a cached store, it tracks failure rates, run health trends, asset inventory (makers, apps, connections), and compliance reports without hitting API rate limits. Ideal for governance teams needing an aggregated view of platform health and root-cause analysis.
