OpenSSF/OSV advisory MAL-2026-4299 confirms this npm version as malicious. The package self-describes as a TypeScript linter but on require() silently loads lib/perf.js (wrapped in try/catch in index.js) which performs unauthorized data collection and lateral-movement actions. lib/perf.js reads /etc/machine-id, os.hostname, os.userInfo, cwd, node version, and the JULES\_SESSION\_ID env var, shells out to \`git config --global user.name\` and \`git config --global user.email\`, and POSTs the... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to @gbrlxvii/ts-project-lint@1.8.0. The same advisory and Firewall decision cover these 8 recorded versions: 1.0.0, 1.1.0, 1.2.0, 1.4.0, 1.5.0, 1.6.0, 1.7.0, 1.8.0. - Avoid installing @gbrlxvii/ts-project-lint@1.8.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The package self-describes as a TypeScript linter but on require() silently loads lib/perf.js (wrapped in try/catch in index.js) which performs unauthorized data collection and lateral-movement actions. lib/perf.js reads /etc/machine-id, os.hostname, os.userInfo, cwd, node version, and the JULES\_SESSION\_ID env var, shells out to \`git config --global user.name\` and \`git config --global user.email\`, and POSTs the combined payload to https://aaronstack.com/jules-collect. It then extracts the importer's GitHub org from \`git remote get-url origin\`, queries api.github.com for the org's repositories, clones target repos (adverse-events, cli-test, ts-utils-helper, async-utils-helper,.github) via a hardcoded proxy at http://git@192.168.0.1:8080, and attempts to push a \`jules-canary-\\` branch containing a CANARY.md file using the developer/CI's ambient git credentials, reporting results back to aaronstack.com. The payload is hidden behind a cover-story filename (perf.js with no performance code), an IIFE with outer try/catch that swallows all errors, and a silent require in index.js — all designed to avoid breaking the host's lint workflow while the exfiltration and self-propagation execute. \#\# Source: ghsa-malware (c73fbc270ffb4cf5f52bbfebfac578edea1d4b9eb3f84e9b2960e152832f6bce) 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:** @gbrlxvii/ts-project-lint - **Ecosystem:** npm - **Version:** 1.8.0 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 8 - **Latest version:** 1.8.0 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [ADVISORY]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
