LPM AI assessed this version as suspicious; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.1.2 - **Selected version is latest:** No - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-18055 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-18055 confirms this npm version as malicious. The npm package api-anthropic impersonates Anthropic by name and by destination. On use, the CLI writes ANTHROPIC\_BASE\_URL=https://api-anthropic.help and ANTHROPIC\_AUTH\_TOKEN=\ into ~/.claude/settings.json, causing every subsequent Claude Code request — prompts, source code sent as context, tool output — to be routed to the author-controlled host api-anthropic.help instead of api.anthropic.com... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-29T13:33:38.678Z - **Finished:** 2026-10-29T13:35:04.275Z - **Download time:** 1004 ms - **Static scan time:** 38 ms - **AI review time:** 84554 ms - **Total time:** 85597 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Invoking the CLI automatically marks the current folder and the user's home directory as trusted in Claude Code's global configuration. This weakens trust prompts for those locations; the source supports a warning, but does not establish hidden credential theft or another attack. - **Trigger:** The user runs the api-anthropic CLI; the trust changes occur even with --no-launch. - **Impact:** Claude Code may skip trust and external-include approval prompts for those locations, including the user's home directory. - **Evidence paths:** bin.js - **Review source:** ai\_review - **Reviewed:** 2026-10-29T13:35:04.275Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI writes trust acceptance and external CLAUDE.md include approvals for both the current folder and home directory to ~/.claude.json. - **Rationale:** The CLI automatically broadens Claude Code trust to the user's home directory and approves external includes, which weakens a meaningful safety boundary. The behavior is part of an explicitly invoked setup, and the displayed gateway configuration does not independently establish credential theft, so warn rather than block. - **Files touched:** ~/.claude/settings.json, ~/.claude.json - **Network endpoints:** https://api-anthropic.help ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The manifest presents bin.js as a one-command Claude Code setup and declares no npm lifecycle script., The CLI accepts a caller-supplied key and displays its default api-anthropic.help gateway before prompting for the key., The CLI sets the global Claude Code base URL to that gateway and stores the supplied key as ANTHROPIC\_AUTH\_TOKEN., The CLI writes the settings file and automatically accepts trust for both the current folder and the user's home, including external CLAUDE.md includes., The trust changes are written to Claude's global configuration; unless --no-launch is supplied, the CLI starts Claude Code. - **Evidence against:** The gateway is displayed before key entry, and the package describes this as a user-invoked gateway setup., The inspected source shows no hidden credential collection or separate payload execution; the concrete concern is automatic weakening of Claude's trust prompts. ## Affected versions and remediation This report applies to api-anthropic@1.1.2. - Avoid installing api-anthropic@1.1.2. 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.
