OpenSSF/OSV advisory MAL-2026-5716 confirms this npm version as malicious. The package advertises itself as a credential-transfer CLI but implements transfer by reading the user's Anthropic Claude Code credentials (\`~/.claude/.credentials.json\`, \`~/.claude.json\`) and POSTing them to a single hardcoded author-owned endpoint, \`https://tfer.jha-anurag2017.workers.dev\`, with no end-to-end encryption. The same request body includes a precise host fingerprint built in \`cmdPush\`... ## 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 beamz@1.0.8. - Avoid installing beamz@1.0.8. 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 advertises itself as a credential-transfer CLI but implements transfer by reading the user's Anthropic Claude Code credentials (\`~/.claude/.credentials.json\`, \`~/.claude.json\`) and POSTing them to a single hardcoded author-owned endpoint, \`https://tfer.jha-anurag2017.workers.dev\`, with no end-to-end encryption. The same request body includes a precise host fingerprint built in \`cmdPush\` (index.js:88-108): \`os.hostname()\`, OS username, local IPv4/IPv6, MAC address, public IP, country/city/ISP/timezone (resolved via ipapi.co), CPU model and core count, and total RAM — far more than is necessary to move credentials between a user's own machines. The Worker URL is set in index.js:9 (\`const WORKER\_URL = process.env.BEAMZ\_URL || "https://tfer.jha-anurag2017.workers.dev"\`) and the credential read+POST sits in \`cmdPush\` (index.js:62-65, 121). The package ships an empty README, so installers have no disclosure that third-party Anthropic credentials and machine identifiers are passing through author infrastructure. The harm fires when the user runs the CLI (\`beamz push\`, also the default action), so the trigger is on user invocation rather than at install time, but the destination is hardcoded, author-controlled, and not the user's own server — the silent-relay shape: callers believe they are using a credential-sync tool, and the tool quietly delivers their secrets and a machine fingerprint to the author. ## 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:** beamz - **Ecosystem:** npm - **Version:** 1.0.8 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 6 - **Latest version:** 1.0.8 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
