Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source, so a manually published version cannot be tied back to a reviewed commit.

source-diff obfuscated-file:build/modules/workbox-precaching.prod.v2.0.0.mjs AI (source-diff): Standard minified ES module production build artifact from Google's Workbox project; Apache 2.0 licensed, accompanied by source maps, contains only service worker caching logic. ai
source-diff obfuscated-file:build/importScripts/workbox-precaching.dev.v2.0.0.js AI (source-diff): Standard minified build artifact from Google's Workbox project; Apache 2.0 licensed, accompanied by source maps, contains only service worker caching logic. ai
source-diff obfuscated-file:build/importScripts/workbox-precaching.prod.v2.0.0.js AI (source-diff): Standard minified production build artifact from Google's Workbox project; Apache 2.0 licensed, accompanied by source maps, contains only service worker caching logic. ai

source-diff obfuscated-file:build/workbox-precaching.prod.js AI (source-diff): Production build artifact (minified browser JS) for a Google Workbox library. The code is clearly a service worker precaching implementation with no malicious patterns. Expected for this package type. ai
publish-pattern new-deps-added AI (publish-pattern): workbox-core is the official shared core of the Workbox ecosystem, published by the same Google team. Adding it as a dependency in v4.0.0 is part of the documented modular refactor. ai
source-diff large-new-source-files AI (source-diff): v4.0.0 was a major architectural rewrite of Workbox; new source files are expected and consistent with the legitimate release history. ai
source-diff obfuscated-file:build/importScripts/workbox-precaching.dev.v1.2.0.js AI (source-diff): workbox-precaching ships minified build bundles as its primary distribution format; these are standard bundler outputs with Apache 2.0 headers, not malicious obfuscation. ai
source-diff obfuscated-file:build/modules/workbox-precaching.prod.v1.2.0.mjs AI (source-diff): workbox-precaching ships minified build bundles as its primary distribution format; these are standard bundler outputs with Apache 2.0 headers, not malicious obfuscation. ai
provenance no-provenance AI (provenance): Package predates Sigstore provenance by years; no-provenance is expected for this vintage Google package. ai
source-diff obfuscated-file:build/modules/workbox-precaching.dev.v1.2.0.mjs AI (source-diff): workbox-precaching ships minified build bundles as its primary distribution format; these are standard bundler outputs with Apache 2.0 headers, not malicious obfuscation. ai
source-diff obfuscated-file:build/importScripts/workbox-precaching.prod.v1.2.0.js AI (source-diff): workbox-precaching ships minified build bundles as its primary distribution format; these are standard bundler outputs with Apache 2.0 headers, not malicious obfuscation. ai
maintainer-change maintainer-removed AI (maintainer-change): Removal of snugug alongside addition of tomayac reflects a routine maintainer handoff within Google's Workbox team, not a hostile takeover. ai
maintainer-change maintainer-added AI (maintainer-change): tomayac is a known Google engineer; addition is consistent with legitimate team transition within the GoogleChrome/workbox project. ai
provenance publisher-changed AI (provenance): tomayac is a known Google DevRel engineer; transition from tropicadri to tomayac is consistent with internal Google team rotation for the Workbox project. ai

2 findings
INFO No provenance attestation provenance

[Accepted risk] Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

INFO Publisher changed: tomayac → swissspidy (on 2025-11-19) provenance

[Accepted risk] This version was published by a different npm account than previous versions on 2025-11-19. This could indicate a legitimate maintainer transition or an account compromise.
