This detection rule identifies Magecart malware activity by monitoring for malicious script injections into legitimate e-commerce websites, which adversaries use to exfiltrate sensitive payment card data through compromised third-party services and supply chain vectors. A proactive hunt in Azure Sentinel is essential because these attacks often bypass traditional perimeter defenses by leveraging trusted vendor relationships, requiring continuous visibility into web traffic anomalies to prevent undetected financial data breaches.
