defender for storage

Defender for Storage is Microsoft's cloud-native security solution for Azure Blob Storage, designed to detect and respond to active threats targeting object stores. Recent discussions on WindowsForum highlight that Azure Blob Storage is under escalating attack, with threat actors exploiting predictable names, leaked credentials, permissive shared access signatures (SAS), and weak network controls. The attack chain involves reconnaissance, persistence, lateral movement, and data exfiltration, often using legitimate Azure tooling like AzCopy. Defender for Storage provides alerts and signals to help defenders identify these malicious activities. Topics covered include attack chain analysis, practical defenses, and the importance of treating Blob Storage as a battleground. The tag focuses on cloud security, threat intelligence, and Microsoft's defensive capabilities for Azure storage workloads.
