Skill UI

This skill provides a comprehensive workflow to extract Indicators of Compromise (IOCs) from malware samples and analysis reports. It covers file hashes (SHA256, MD5), network artifacts (IPs, domains, URLs from strings and PCAPs), and host-based indicators (registry keys, file paths, mutexes) from sandbox reports. It is essential for threat intelligence sharing, building blocklists, and creating detection signatures (YARA, Snort).

This guide details how to hunt for DCSync attacks, a technique used to steal password hashes from Active Directory. It involves analyzing Windows Event ID 4662 to identify unauthorized DS-Replication-Get-Changes requests originating from non-domain-controller accounts. Essential for incident response and threat detection.

This skill guides security analysts through advanced threat-hunting methodologies focused on detecting DNS-based persistence. It analyzes passive DNS history, zone file audits, and API data (like SecurityTrails) to identify unauthorized record modifications, subdomain takeovers, and DNS hijacking attempts that bypass traditional security controls. Ideal for SOC analysts and threat hunters.

A comprehensive guide and detection methodology for identifying covert communication channels utilizing DNS records. This technique analyzes Zeek dns.log for indicators such as high-entropy subdomains, excessive query volume, unusually long query lengths, and abnormal record type distributions, which suggest data exfiltration or Command and Control (C2) activity.

This skill detects domain fronting, an advanced technique used by attackers to mask Command and Control (C2) traffic. It analyzes proxy/web gateway logs for mismatches between the TLS SNI field and the HTTP Host header, combined with deep TLS certificate inspection using pyOpenSSL. This is crucial for security teams investigating sophisticated network threats and validating detection coverage.

This guide details the implementation of SPF, DKIM, and DMARC—the three core pillars of email authentication. It provides a comprehensive workflow, including DNS record setup and best practices, to prevent domain spoofing, validate message integrity, and enforce strong anti-phishing policies across your organization's email system. Essential for building robust email security architecture.

Audits a domain’s email authentication by querying SPF, DKIM, and DMARC DNS records using dnspython, validating syntax/counts, flagging common spoofing risks, and producing remediation guidance.

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 guide details the implementation of a robust, ransomware-resilient backup architecture following the extended 3-2-1-1-0 rule. It covers critical steps such as classifying assets, defining RPO/RTO, implementing immutable or air-gapped storage, and isolating backup credentials from the production domain. Use this knowledge to design a multilayered defense against data loss and ensure reliable recovery points.

This guide details how to implement NextDNS as a zero-trust DNS filtering layer. By utilizing encrypted resolution (DoH/DoT) and real-time threat intelligence, it blocks malicious domains, prevents data exfiltration, filters ads/trackers, and enforces granular security policies across all endpoints, aligning with Zero Trust principles and enhancing overall network security.

BloodHound is an open-source reconnaissance tool that leverages graph theory to analyze Active Directory relationships. This guide details the process of collecting AD data using SharpHound and visualizing complex attack paths. It helps identify potential privilege escalation chains, trust abuses, and misconfigurations necessary for an attacker to move from a low-privilege user account to Domain Admin, making it essential for advanced red-teaming and security auditing.

Conducts a comprehensive Active Directory penetration test, covering domain enumeration, misconfiguration discovery, and attack path analysis using BloodHound. Techniques include exploiting Kerberos weaknesses (Kerberoasting, AS-REP Roasting) and escalating privileges via DCSync and constrained delegation, culminating in domain compromise demonstration.
