This hypothesis targets the initial access and persistence stages of the Mozi malware family, which leverages malicious URLs to establish a backdoor for remote command execution and data exfiltration. Proactively hunting for these indicators in Azure Sentinel is critical because Mozi often propagates via phishing campaigns and compromised domains, allowing attackers to maintain a foothold in the environment before traditional endpoint detections can trigger.
