OS Analysis with HELK

Aaron Rosenmund

HELK provides machine learning and graph analysis to world class windows log collection and analysis across your enterprise not found in other tools, for free! In this course, you will learn to hunt adversary activity on endpoints using HELK.

Though many cyber attack techniques can be effectively and heuristically identified by analyzing the endpoint logs, there are surprisingly few capabilities that focus solely on parsing windows logs and OS data and providing a platform to perform advanced statistical analysis. In this course, OS Analysis with HELK, you’ll cover how to utilize Hunt ELK to detect adversary endpoint attack techniques in an enterprise environment. First, you’ll see the gap that HELK fills with Windows event log analysis. Next, you'll explore how to operate the advanced hunt features provided by HELK. Finally, you’ll learn how to analyze a live dataset to hunt for adversary activity. When you’re finished with this course, you’ll have the skills and knowledge to detect these techniques: Kerberoasting T1208, Bits Jobs T1197, and indicator removal on hosts T1070 using HELK.

Reviews summary

Helk for advanced os threat hunting

According to students, this course provides a positive and highly practical deep dive into OS analysis with HELK for cybersecurity professionals. Learners particularly praise the hands-on labs and real-world examples, which are directly applicable to threat hunting and detecting adversary techniques like Kerberoasting. The instructor's clarity in explaining complex concepts is frequently highlighted. However, some learners experienced challenges with lab environment setup and resource consumption, indicating a need for strong foundational knowledge in virtualization. A few also noted potential outdated content or sync issues with the latest HELK versions, though the core value remains high.

Good foundation, but advanced learners desire more in-depth content.

"I felt some parts could be more in-depth, especially regarding advanced queries or integrating with other security tools."

"My main feedback would be to maybe include more challenges or advanced scenarios for practicing detection rules."

"It covers what it promises, but an advanced module would be a great addition."

Highly relevant for modern cybersecurity and endpoint analysis.

"This course is a game-changer for anyone wanting to up their game in endpoint forensics and threat detection using open-source tools."

"Perfectly structured and extremely relevant for modern cyber defense."

"It's rare to find such focused and actionable content for security analysis."

The instructor effectively clarifies complex security topics.

"The instructor explains complex concepts around Windows event logs and HELK deployment with incredible clarity."

"The instructor breaks down complex topics into digestible chunks."

"I appreciated the clear explanations of Windows event IDs and how HELK leverages Elastic Stack."

Delivers highly practical experience in threat hunting.

"The hands-on labs are super practical and directly applicable to threat hunting in a real-world enterprise environment."

"The practical examples of detecting T1208 and T1197 were extremely valuable."

"The labs are the highlight – truly hands-on and reinforce the concepts beautifully."

"I found the hands-on exercises for detecting various MITRE ATT&CK techniques spot on and actionable."

Some course materials might be slightly out of sync with current HELK versions.

"Some of the older content (like specific versions of tools) might need an update..."

"It seems some instructions or versions in the course were a bit out of sync with the latest HELK release..."

"The practical exercises sometimes lagged behind, particularly with HELK updates."

Learners may face difficulties with HELK lab setup and resource use.

"I struggled with the lab environment setup. It felt a bit buggy and consumed a lot of resources..."

"I spent a lot of time troubleshooting my VM environment, which was frustrating."

"The content itself is good if I can get past the technical hurdles, but it's definitely not for beginners who aren't comfortable with virtual machines and networking basics."
