BinaryAlert is an open-source serverless AWS pipeline that provides automated malware detection capabilities for files uploaded to S3 buckets. The system operates by automatically scanning any file uploaded to a designated S3 bucket using a configurable set of YARA rules. When a file is uploaded, BinaryAlert immediately processes it through the scanning pipeline without requiring manual intervention. The tool generates alerts as soon as any YARA rule matches are detected in the scanned files. This immediate notification system enables incident response teams to quickly identify potential threats and take containment actions before malware can spread throughout the environment. BinaryAlert leverages AWS serverless architecture, making it scalable and cost-effective for organizations that need continuous file monitoring. The YARA rule configuration allows users to customize detection capabilities based on their specific threat landscape and security requirements. The system includes documentation and community support through unofficial Slack channels, providing resources for implementation and troubleshooting.
