High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% scripts/postinstall.js is heavily obfuscated (obfuscator.io with rotated base64-RC4 string array and a self-defending regex tamper check that infinite-loops on debuggers/beautifiers). On \`npm install\`, the postinstall hook walks up from process.cwd() to fingerprint the parent project, selects a remote URL based on os.platform() (linux/darwin/win32), fetches the response body via http(s).get into a Buffer, writes it to a file under os.tmpdir(), then spawns it via child\_process.spawn(process.execPath, \[tmpFile\], {detached: true, stdio: 'ignore', env: {...process.env,...}}).unref() — a classic detached install-time remote code dropper that ships the installer's full environment to the spawned process. The package's library surface is non-functional (declared main \`dist/index.js\` only re-exports \`../src/index.js\`, but no \`src/\` directory ships in the tarball), and the publisher identity (\`welcome-onboarding-web.io\` with fabricated jira/docs/github/npm subdomains) does not correspond to a real organization. The package's only effect on install is execution of the obfuscated dropper. ## 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:** @welcome-onboarding-web/mobile-focus-account-beta-merging - **Ecosystem:** npm - **Version:** 4.28.7 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 4.28.7 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]()
