Hunt Hypothesis

This hunt detects adversary behavior characterized by the presence of fifty-two unknown malware indicators that may signal early-stage infiltration or zero-day threats within the environment. Proactively hunting for these IOCs in Azure Sentinel is critical to identify and isolate potential malicious activity before it escalates into a confirmed incident, given the high severity associated with unidentified malware signatures.

IOC Summary

Malware Family: Unknown malware Total IOCs: 52 IOC Types: ip:port, url, domain, sha256_hash
