Malicious File Detection

Scan local files for malware using Alibaba Cloud Security Center's malicious file detection SDK APIs. Supports single file scanning and batch directory scanning.

Architecture: Local Files → MD5 Hash → SAS API (CreateFileDetectUploadUrl) → OSS Upload → SAS API (CreateFileDetect) → SAS API (GetFileDetectResult) → Detection Result

Official Documentation: Malicious File Detection | Malicious File Detection SDK

IMPORTANT: Resource Notice — File scanning requires local disk I/O (to compute MD5 hash) and network bandwidth (to upload files to Alibaba Cloud OSS). Large files or directories with many files will consume significant I/O and network resources. Always inform the user before starting a scan.
