Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% ai-sdk-helpers@1.2.1 is a typosquat impersonating the Vercel AI SDK ecosystem (homepage ai-sdk.guide, author 'AI SDK Guide \'). On npm install, scripts/postinstall.js reads installer-owned identity files it did not create — ~/.gitconfig, ~/.config/git/config,./.git/config (for the developer's git email) and ~/.config/gh/hosts.yml (for the GitHub CLI login and email) — and collects os.hostname(), os.userInfo().username, process.cwd(), and CI environment variables. The collected data is POSTed in plaintext JSON to https://npm-package-logger-228835561205.europe-west1.run.app/ (scripts/postinstall.js line 147 / line 163). Comments in the script claim the data is 'anonymous' and 'one-way hashed', but the traced payload ships the raw scmEmail, githubLogin, githubEmail, hostname, username, and cwd fields. The tarball additionally ships scripts/publish-versions.sh, whose comment 'This creates the appearance of an active, maintained package' documents a republish loop of 21 fake versions to manufacture apparent activity. The combination of typosquat naming against Vercel's AI SDK, install-time harvest of developer→employer identity from installer-managed git/GitHub config, exfiltration to a third-party Cloudflare Run endpoint, and the shipped version-spam script establishes a coordinated install-time identity-exfiltration campaign targeting AI/LLM developers. \#\# Source: ghsa-malware (e33e9e9c454638a63c5ef112aeb9e9abc2d805effd5dc0ceebf54746cf7ef327) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## 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:** ai-sdk-helpers - **Ecosystem:** npm - **Version:** 1.4.5 - **Version published:** 2026-07-07T13:22:25.324Z - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-07-09T17:45:08.964Z - **Known versions:** 25 - **Latest version:** 1.4.5 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
