High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% brioche-apl-dev-env is a dependency-confusion package: it takes a name that looks like an internal project, uses an inflated version (100.0.0) so it outranks private-registry versions, and runs \`node setup.js || true\` as a preinstall script on npm install. setup.js sends the hostname, username, working directory, OS, architecture, Node.js version and configured npm registry, with a per-package tracking token, in an HTTPS POST to \`https://s85r5k14qk.execute-api.us-east-1.amazonaws.com/prod/hook\`. The npm account amel10 published brioche-apl-dev-env and 9 similar packages within two minutes on 2026-09-30, all with the same setup.js. --- \#\# Source: amazon-inspector (637c99e6cd2bd8e143f01f5f522a7497375a24072fca131057cfd40ae0bb0d3e) The package declares a \`preinstall\` script that runs \`setup.js\` during \`npm install\`. That script collects installer host identifiers (hostname, OS username, current working directory, platform/arch, Node.js version, configured npm registry) together with a static per-package token, serializes them as JSON, and POSTs them to a hardcoded endpoint at https://s85r5k14qk.execute-api.us-east-1.amazonaws.com/prod/hook. The package is presented as a small utility (vowel-counting) but its only install-time effect is this outbound beacon to an author-controlled AWS API Gateway URL. The version number (100.0.0) and package naming are consistent with a dependency-confusion lure targeting an internal \`brioche-apl-\*\` namespace, and the transmitted fields (internal hostname, username, cwd, configured registry) are exactly the reconnaissance data used to identify successfully hijacked internal builds. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** brioche-apl-dev-env - **Ecosystem:** npm - **Version:** 100.0.0 - **Version published:** 2026-09-30T07:05:00.241Z - **Package first seen:** 2026-10-04T23:40:06.263Z - **Package last seen:** 2026-10-04T23:40:06.263Z - **Known versions:** 1 - **Latest version:** 100.0.0 - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]()
