Using LLMs and ESRE to find similar user sessions
In our previous article, we explored using the GPT-4 Large Language Model (LLM) to condense Linux user sessions. In the context of the same experiment, we dedicated some time to examine sessions that shared similarities. These similar sessions can subsequently aid the analysts in identifying related suspicious activities.
Using LLMs to summarize user sessions
In this publication, we will talk about lessons learned and key takeaways from our experiments using GPT-4 to summarize user sessions.
Forget vulnerable drivers - Admin is all you need
Bring Your Own Vulnerable Driver (BYOVD) is an increasingly popular attacker technique whereby a threat actor brings a known-vulnerable signed driver alongside their malware, loads it into the kernel, then exploits it to perform some action within the kernel that they would not otherwise be able to do. Employed by advanced threat actors for over a decade, BYOVD is becoming increasingly common in ransomware and commodity malware.
Detect domain generation algorithm (DGA) activity with new Kibana integration
We have added a DGA detection package to the Integrations app in Kibana. In a single click, you can install and start using the DGA model and associated assets, including ingest pipeline configurations, anomaly detection jobs, and detection rules.
