This guide details the exploitation of the critical Zerologon vulnerability (CVE-2020-1472) in Active Directory Domain Controllers. It demonstrates the methodology for resetting the DC machine account password to empty, achieving full domain compromise. Subsequent steps include dumping domain credentials using DCSync. Essential for authorized red-teaming and security validation.

A comprehensive guide and toolkit for extracting, parsing, and analyzing Windows Event Logs (EVTX). This method utilizes industry-leading tools like Chainsaw and Hayabusa, along with Sigma rules, to perform deep digital forensics. It is specifically designed to detect critical security indicators such as lateral movement, persistence mechanisms, privilege escalation, and unauthorized access attempts on Windows systems.

This comprehensive guide details security best practices for hardening Docker containers and their underlying infrastructure (daemon, runtime, images). It aligns with standards like the CIS Docker Benchmark v1.8.0, enforcing least privilege through non-root users, capability dropping, read-only filesystems, and advanced security profiles (seccomp/AppArmor). Essential for building highly secure, compliant, and production-ready container environments.

This guide details how to harden the Docker daemon configuration using daemon.json. It implements critical security measures such as user namespace remapping, disabling inter-container communication (ICC), enforcing no-new-privileges, and setting up TLS client authentication. Use this when aiming to prevent container breakout, privilege escalation, or meeting CIS benchmark compliance requirements.

Detects data-staging activity (MITRE ATT&CK T1074) by analyzing EDR/Sysmon process-creation and file-system telemetry. This skill monitors for archive creation (7-Zip, RAR, tar), unusual file consolidation from multiple directories, and suspicious activity in temporary or hidden paths. It is essential for threat hunting, building robust detection rules, and validating security monitoring coverage against data exfiltration attempts.

This guide details how to hunt for DCSync attacks (MITRE ATT&CK T1003.006) in Active Directory environments. It focuses on analyzing Windows Security Event ID 4662, specifically looking for DS-Replication-Get-Changes requests originating from non-domain-controller accounts. This technique is critical for incident response, purple teaming, and detecting unauthorized credential theft via Active Directory replication abuse.

This skill provides a structured methodology for threat hunting DNS-based persistence mechanisms. It detects unauthorized changes such as DNS hijacking, dangling CNAME records enabling subdomain takeover, wildcard DNS abuse, or unauthorized NS delegation modifications. By utilizing passive DNS history (e.g., SecurityTrails API) and auditing cloud DNS logs (Route53, Azure, Cloudflare), users can identify persistent attack vectors that survive traditional remediation efforts.

This skill detects command-and-control (C2) traffic hidden using domain fronting techniques. It analyzes proxy and web gateway logs by comparing discrepancies between the TLS SNI field and the HTTP Host header. By inspecting these mismatches and correlating them with known CDN provider properties, it helps security analysts hunt for sophisticated network evasion tactics.

This skill helps detect NTLM relay attacks (T1557.001) by analyzing Windows Security Event ID 4624 (logon type 3) for NTLMSSP usage. It flags critical anomalies such as IP-to-hostname mismatches, evidence of LLMNR/NBT-NS poisoning, rapid cross-domain authentication, and verifies SMB signing status. It is essential for proactive threat hunting and security incident investigation in Active Directory environments.

This comprehensive guide outlines a structured methodology for threat hunting and incident response, focusing on identifying adversary persistence mechanisms across Windows endpoints. It covers critical areas such as Registry Run/RunOnce keys, services, scheduled tasks, WMI event subscriptions, and COM hijacking. Use this workflow to proactively detect unauthorized backdoors, strengthen detection rules, and assess overall security posture against MITRE ATT&CK techniques (T1547).

This guide details a threat hunting technique for detecting persistence mechanisms utilizing Windows Registry Run keys (T1547.001). By analyzing Sysmon Event ID 13 logs, it identifies suspicious auto-start entries pointing to temporary directories, encoded PowerShell commands, or abused LOLBins. Essential for SOC analysts and security engineers investigating incidents and developing robust detection rules.

A comprehensive guide for hypothesis-driven threat hunting focusing on Windows Scheduled Task persistence (T1053). This methodology guides the creation of advanced SIEM/EDR queries against critical events like task creation (Event ID 4698), suspicious actions, and unusual scheduling patterns. Essential for incident response, proactive threat hunting, and security assessments.
