A comprehensive guide for advanced threat hunting, focusing on detecting DLL side-loading and search-order hijacking (MITRE T1574). It instructs users to analyze Sysmon Event ID 7 logs, validate file signatures and hashes, and identify path anomalies to uncover APT persistence mechanisms. Essential for incident response and proactive threat detection in enterprise environments.

A comprehensive guide and workflow for detecting Mimikatz and similar credential-dumping activities. It utilizes command-line pattern matching, LSASS memory access signatures, binary indicators, and in-memory analysis. Ideal for threat hunting, scoping compromises during incident response, or validating detection coverage in purple team exercises using EDR/SIEM data.

Deploy Zeek for passive network analysis to generate structured logs (DNS, HTTP, etc.). This tool detects behavioral anomalies like DNS tunneling or beaconing, complementing traditional signature-based IDS tools. It is ideal for threat hunting and incident response, feeding rich protocol metadata into SIEM platforms.

This skill provides comprehensive guidance on detecting network reconnaissance and port scanning activities using industry-standard IDS/IPS systems like Suricata and Snort. It covers various scanning techniques (e.g., SYN, FIN, NULL, Xmas scans, UDP sweeps) and advanced detection methods, including signature matching, threshold-based alerting, and traffic anomaly analysis to identify tools like Nmap and Masscan.

A comprehensive skill for detecting early-stage ransomware indicators before data encryption occurs. It utilizes advanced network detection tools such as Zeek and Suricata, combined with SIEM correlation rules and threat intelligence feeds. This method monitors the entire pre-encryption kill chain, identifying precursor behaviors like initial access broker activity, Cobalt Strike C2 beaconing, credential harvesting (e.g., Mimikatz signatures), and data staging attempts, enabling timely incident response and containment.

This skill demonstrates how to exploit vulnerabilities in JWT implementations, specifically algorithm confusion. It targets APIs that fail to strictly enforce the signing algorithm, allowing attackers to downgrade signatures (e.g., RS256 to HS256) or bypass signature verification entirely (alg:none). Use this for authorized penetration testing of API security and cryptographic integrity.

Scans web server roots for high-entropy files, suspicious PHP/JSP/ASP payloads, and recent modifications to flag obfuscated webshells via entropy thresholds, regex signatures, and file metadata.

This skill covers the implementation of Ed25519 digital signatures, a high-performance algorithm utilizing the Curve25519 structure. It details key pair generation, message signing, and signature verification. Ed25519 offers superior performance, determinism, and side-channel resistance compared to RSA and ECDSA. Use this skill for establishing robust authentication, ensuring data integrity, and securing system components like code or APIs.

This guide details the process of file carving using the Foremost tool in digital forensics. It demonstrates how to recover deleted or fragmented evidence (such as documents, images, and archives) from raw disk images or unallocated space by analyzing file headers and footers, independent of the file system's index. It also covers advanced techniques using custom signatures and high-performance alternatives like Scalpel.

A specialized tool for authorized penetration testing and security assessments. It exploits the vulnerability of JWT libraries that accept tokens with the "alg": "none" header, bypassing cryptographic signature verification. Users can craft tokens with arbitrary claims (e.g., elevated privileges, impersonation) to validate that a target server correctly rejects unsigned JSON Web Tokens.

A comprehensive guide detailing how to perform rapid malware triage and classification using YARA rules. Learn to write sophisticated rules that match file patterns, unique strings, byte sequences, and structural PE characteristics. Ideal for automating signature-based scanning, developing custom detection rules for zero-day threats, and building robust analysis pipelines.

This skill demonstrates how to craft and inject custom, malformed, or spoofed network packets using tools like Scapy and hping3. It is designed for authorized cybersecurity assessments to rigorously test firewall rules, Intrusion Detection/Prevention Systems (IDS/IPS) signatures, anti-spoofing controls, and overall network stack resilience against protocol anomalies and fragmentation attacks. Use only in controlled, authorized environments.
