Workshop: Rapid Endpoint Investigations for Linux and Mac

Together, through hands-on labs and demonstrations, we’ll walk through gathering artifacts from Linux and Mac endpoints using Velociraptor Offline Collectors, CatScale, and UAC (Unix-like artifact collector) scripts, rapidly searching and analyzing artifacts, and identifying indicators of compromise!

Course Length: 4 Hours

Includes a Certificate of Completion



Description

You’ve received a “true positive” security alert for a Linux or Mac endpoint. This is not a drill! This is war and you need to take rapid, decisive steps to determine:

  • Has the endpoint been compromised?

  • Have other systems been impacted?

  • What actions should come next?

Together, through hands-on labs and demonstrations, we’ll walk through gathering artifacts from Linux and Mac endpoints using Velociraptor Offline Collectors, CatScale, and UAC (Unix-like artifact collector) scripts, rapidly searching and analyzing artifacts, and identifying indicators of compromise!

FAQ

Labs:

All labs will be completed through cloud VM via web browser.

You will need to register via SkillBit (MetaCTF), to pay a small fee for Virtual Machine resource utilization (approx. $5 for a four-hour workshop), and a modern web browser to access the workshop Cloud VM.

Who should attend:

This workshop is intended for security analysts who review and respond to security alerts and perform endpoint investigations.

Audience skill level:

Beginner/Intermediate

To maximize the value of this workshop, attendees should be comfortable using Windows and have basic familiarity with Linux command line (shell).

Key takeaways:

  • Developing a rapid endpoint investigation workflow

  • Selecting the most useful investigative artifacts for Linux/Mac endpoint investigations

  • Building, deploying and executing triage collections on Linux/Mac endpoints

  • Understanding and analyzing key investigative artifacts

  • Analyzing MacOS unified log (UL) for investigations

  • Customizing rapid endpoint investigations for your environment
