Hunt Hypothesis

This hypothesis targets adversaries leveraging malicious ELF (Executable and Linkable Format) binaries hosted on known malicious URLs to execute Linux-based payloads, a common tactic for compromising cloud workloads and containerized environments. Proactively hunting for these indicators in Azure Sentinel is critical to identify compromised hosts or data exfiltration attempts before the ELF binaries can establish persistence or lateral movement within the Azure infrastructure.
