This hypothesis targets adversaries leveraging the ELF file format to distribute malicious payloads or execute code via URLs listed in the URLhaus threat intelligence feed. Proactively hunting for these specific indicators in Azure Sentinel allows the SOC to identify compromised endpoints or suspicious web traffic before the ELF-based malware can establish persistence or exfiltrate data.
