A comprehensive guide for security professionals to detect data exfiltration by analyzing network telemetry (Zeek, Suricata) and logs. Techniques include identifying DNS tunneling, unusual cloud uploads, and detecting large/abusive data flows across various channels during incident response and proactive threat hunting.

A comprehensive guide to identifying covert data exfiltration channels using Zeek logs. This technique analyzes DNS traffic for high-entropy subdomains, unusually long query lengths, abnormal record types (TXT/NULL), and excessive query volume, which are key indicators of malicious DNS tunneling or command-and-control (C2) activity.

This tool analyzes Windows Event Logs (ID 4688, Sysmon ID 1) and WMI-Activity Operational events to detect suspicious lateral movement. It specifically hunts for WmiPrvSE.exe spawning child processes (like cmd.exe or powershell.exe) or identifying WMI event subscriptions, which are common indicators of remote code execution and persistence.

This method targets fileless and trigger-based persistence mechanisms on Windows hosts by monitoring WMI event subscriptions (MITRE T1546.003). It hunts for suspicious activity involving WMI Event Filters, Consumers, and Bindings, which are critical indicators during advanced threat hunting and incident response when standard persistence locations are clean.

A comprehensive guide for security professionals to proactively hunt for Indicators of Compromise related to Volume Shadow Copy deletion (T1490). This technique is critical for detecting ransomware preparation and anti-forensics activity. It details using SIEM/EDR platforms to query for specific commands (vssadmin, wmic, PowerShell) associated with deleting system recovery points and shadow copies.

This guide details a structured threat hunting methodology designed to proactively detect sophisticated spearphishing campaigns. It instructs users on correlating indicators across email logs, endpoint telemetry (EDR), and network data (SIEM) to identify targeted threats, supporting incident response and security posture improvement.

A comprehensive guide for conducting hypothesis-driven threat hunting against supply chain compromises (T1195). This skill focuses on querying SIEM/EDR logs to detect indicators of trojanized software updates, compromised dependencies, unauthorized code modifications, and tampered build artifacts. It is crucial when investigating suspected vendor compromises or scoping a build pipeline breach, requiring advanced knowledge of logging systems and threat intelligence.

This skill performs threat hunting for persistence mechanisms by parsing Windows System event logs (Event ID 7045). It specifically detects suspicious service installations, analyzing service binary paths, and correlating these events with advanced telemetry (Sysmon/EDR) to identify indicators of compromise (MITRE ATT&CK T1543.003). Ideal for incident response and security validation.

A comprehensive guide for deploying and managing network deception systems using industry-leading honeypot platforms like OpenCanary, T-Pot, and Cowrie. This skill helps security professionals detect unauthorized access attempts, trace lateral movement, and gather critical threat intelligence by simulating vulnerable services within a controlled environment. Ideal for enhancing network security architecture and creating early warning indicators for intrusions.

Learn how to build and share structured threat intelligence objects, including indicators, malware, and campaigns, using the stix2 Python library. This guide details publishing data via the TAXII 2.1 protocol, making it essential for developing threat intelligence platforms, automating IOC exchange, and creating machine-readable reports for ISAC/ISAO communities.

This skill automates the entire phishing incident response lifecycle using the Splunk SOAR REST API. It processes reported emails, extracts indicators of compromise (IOCs) like URLs and IPs, creates incident containers, attaches artifacts, and triggers automated playbooks for deep analysis and reporting. It is essential for security operations teams needing robust, programmatic incident handling and compliance alignment.

This skill provides a comprehensive guide on integrating Cyber Threat Intelligence (CTI) feeds using STIX 2.1 and TAXII 2.1 standards. It demonstrates how to build both consumer and producer capabilities in Python, covering server discovery, polling collections, and parsing complex STIX objects (Indicators, Malware, Threat Actors). Ideal for professionals building SIEM/TIP integrations or advanced security architectures.
