HAWK is a multi-cloud antivirus scanning API that integrates CLAMAV and YARA engines for malware detection across AWS S3, Azure Blob Storage, and GCP Cloud Storage platforms. The tool operates as a microservice architecture that provides stream-based scanning capabilities using both YARA rules and CLAMAV signatures. It can automatically scan objects stored in S3 buckets and perform automated actions based on scan results. Key scanning capabilities include real-time stream scanning, S3 bucket object scanning, and support for custom YARA rule management. The system can automatically move clean objects to designated buckets while quarantining infected files to prevent further distribution. HAWK maintains up-to-date threat detection through automatic CLAMAV database updates and supports custom YARA rule functionality for specialized detection requirements. The system uses logrus for enhanced logging capabilities and provides comprehensive API endpoints for scanning operations, rule management, system metrics, and health monitoring. The tool is distributed through automated builds available on container registries and supports deployment across multiple cloud storage platforms through its unified API interface.
