HackerNews 编译，转载请注明出处： 谷歌宣布推出一项名为“OSS Rebuild”的新计划，旨在增强开源软件包生态系统的安全性，防范软件供应链攻击。 谷歌开源安全团队（GOSST）的Matthew Suozzo在本周的博客文章中表示：“随着供应链攻击持续针对广泛使用的依赖库，OSS Rebuild能为安全团队提供强大的数据来避免遭受入侵，同时无需增加上游维护者的负担。” 该项目旨在为Python Package Index (Python)、npm (JS/TS) 和 Crates.io (Rust) 软件包注册表提供构建溯源（build provenance），并计划将其扩展到其他开源软件开发平台。 OSS Rebuild 的核心思路是结合利用声明式构建定义（declarative build definitions）、构建工具（build instrumentation）和网络监控能力，生成可信的安全元数据。这些元数据随后可用于验证软件包的来源，并确保其未被篡改。 谷歌表示：“通过自动化和启发式方法，我们确定目标软件包的预期构建定义并重建它。我们将结果与现有的上游制品进行语义比较，对两者进行归一化处理，以消除导致比特级（bit-for-bit）比较失败的不稳定因素（例如，归档压缩差异）。” 成功复现软件包后，构建定义和结果将通过 SLSA Provenance 作为证明机制发布。这使用户能够可靠地验证其来源、重复构建过程，甚至从已知功能基线定制构建。 在自动化无法完全复现软件包的情况下，OSS Rebuild 提供了可替代使用的手动构建规范。 谷歌指出，OSS Rebuild 有助于检测不同类别的供应链入侵事件，包括： 包含公共源代码仓库中不存在代码的已发布软件包（例如 @solana/web3.js 事件） 可疑的构建活动（例如 tj-actions/changed-files 案例） 通过人工审查难以识别的、嵌入在软件包中的异常执行路径或可疑操作（例如 XZ Utils 后门） 除了保护软件供应链，该方案还能改进软件物料清单（SBOM）、加速漏洞响应、增强软件包的可信度，并消除组织依赖 CI/CD 平台负责其软件包安全性的需要。 谷歌解释道：“重建工作通过分析已发布的元数据和制品来推导，并与上游软件包版本进行评估。成功后，将为上游制品发布构建证明，验证上游制品的完整性，并消除许多可能的入侵来源。”       消息来源：thehackernews； 本文由 HackerNews.cc 翻译整理，封面来源于网络； 转载请注明“转自 HackerNews.cc”并附上原文
