Hunt Hypothesis

The hypothesis is that the detected URLs are likely used by adversaries to deliver elf malware, which can execute malicious code and establish persistence. SOC teams should proactively hunt for these URLs in Azure Sentinel to identify and mitigate potential compromise of endpoints and data exfiltration.
