Hunt Hypothesis

This detection identifies adversary behavior where endpoints access newly identified malicious URLs classified with the ELF (Executable and Linkable Format) signature, indicating potential delivery of Linux-based malware or command-and-control traffic. The SOC team should proactively hunt for these indicators in Azure Sentinel to rapidly isolate compromised workloads before they establish persistence or exfiltrate sensitive data within cloud-native environments.
