对象存储(S3/OSS/COS/OBS)Bucket 误配利用。当发现 AWS S3、阿里云 OSS、腾讯云 COS、华为云 OBS 等对象存储服务,或在 HTTP 响应中看到 x-amz-*、x-oss-*、x-cos-* 等 Header 时使用。覆盖 Bucket 枚举、ACL 误配检测、公开读写利用、Bucket 接管、Object 遍历、任意文件上传、Policy 策略滥用。发现任何云存储桶相关的资产或 URL(*.s3.amazonaws.com、*.oss-cn-*.aliyuncs.com、*.cos.*.myqcloud.com 等)都应使用此技能。优先使用 coscli/tccli 操作腾讯云 COS,awscli 操作 AWS S3

From the source SKILL.md

对象存储是云上最常见的暴露面——Bucket 一旦配置公开读写,就等于把文件服务器直接暴露在互联网上。更危险的是 ACL 误配可以让攻击者接管整个 Bucket,进行钓鱼、供应链投毒、数据窃取。
