This guide provides a comprehensive methodology and technical approach for detecting malicious email forwarding rules. It is crucial for threat hunting, incident response, and proactive security assessments to identify persistent access mechanisms used by adversaries for intelligence collection and Business Email Compromise (BEC) attacks. It outlines necessary prerequisites, workflow steps, and key threat indicators (T1114).

This skill provides a methodology to detect data exfiltration attempts hidden within DNS queries. By analyzing Zeek dns.log files, the agent computes Shannon entropy of subdomains, flags unusually long labels, and monitors unique subdomain counts per parent domain. This technique is crucial for identifying malicious tunneling tools like dnscat2 or iodine that bypass traditional security controls.

This script detects and analyzes sophisticated fileless malware techniques that operate entirely in system memory. It specializes in identifying threats that utilize Living Off the Land Binaries (LOLBins), WMI event subscriptions, and registry-resident payloads, bypassing traditional file-based security controls. It is ideal for forensic investigations, threat hunting, and building advanced detection rules in modern enterprise environments.

This skill guides the detection of Golden Ticket attacks within Active Directory by analyzing Kerberos logs (Event IDs 4768, 4769, 4771). It hunts for critical anomalies, such as mismatched encryption types (e.g., RC4 in AES environments), impossible ticket lifetimes, or service tickets appearing without a prior ticket grant request. This is essential for post-breach assessment and advanced threat hunting in domain environments.

This skill provides structured procedures for detecting Golden Ticket attacks, a severe threat involving forging Kerberos Tickets in Active Directory. It analyzes Windows Event ID 4769 for indicators such as RC4 encryption downgrades, abnormal ticket lifetimes, and inconsistencies in TGS/TGT requests. Designed for SOC analysts and threat hunters using SIEM platforms (Splunk/Elastic) to enhance security monitoring coverage against credential theft.

This skill provides structured procedures and Python examples for detecting internal data exfiltration. It analyzes endpoint, cloud, and email logs by establishing behavioral baselines and performing statistical anomaly detection. Use cases include investigating insider threats, monitoring DLP policy violations, and building robust User and Entity Behavior Analytics (UEBA) rules for SOC teams.

This skill implements User and Entity Behavior Analytics (UEBA) to detect sophisticated insider threats. It builds behavioral baselines from diverse log sources (authentication, file access, network) using Elasticsearch/OpenSearch. It calculates anomaly scores and performs peer group analysis to identify deviations indicative of data exfiltration, privilege abuse, or unauthorized access patterns.

This guide outlines a comprehensive threat hunting methodology for detecting Kerberoasting attacks. It focuses on monitoring for anomalous Kerberos TGS requests targeting service accounts with SPNs, which are indicators of brute-force or offline password cracking attempts. Use this workflow during proactive security assessments, incident response, or when analyzing SIEM/EDR telemetry to identify potential lateral movement.

This guide outlines a comprehensive threat hunting methodology for detecting adversary lateral movement within a network environment. It utilizes Splunk SPL queries against rich Windows event data, including authentication logs (4624, 4625), SMB traffic, and Sysmon telemetry. By correlating source-to-destination activity and identifying unusual logon types (RDP, WinRM, SMB), users can proactively track an attacker's path after initial system compromise, fulfilling MITRE ATT&CK T1021 techniques.

This skill provides a comprehensive framework for detecting Living Off the Land Binaries (LOLBAS) abuse, such as misuse of certutil, regsvr32, and mshta. It leverages process telemetry from Sysmon and Windows Event Logs, combined with advanced Sigma rule-based detection and parent-child process anomaly analysis. Ideal for SOC analysts and threat hunters investigating sophisticated adversaries aiming to evade traditional security controls.

This skill provides a structured methodology for detecting persistence and lateral movement via malicious scheduled tasks. It utilizes Sysmon Event IDs (1, 11) and Windows Security Events (4698/4702) to correlate process creation, task file writes, and task registration details. Ideal for threat hunting and building robust detection rules for T1053.005.

This guide details advanced threat hunting techniques to proactively detect Mimikatz execution. It focuses on identifying command-line patterns, unauthorized access to LSASS memory, binary indicators, and known credential dumping techniques (e.g., DCSync, Golden Tickets). Ideal for security analysts, threat hunters, and incident response teams during proactive assessments or active compromise investigation.
