The installed AI harness is visually and operationally altered, obscuring its upstream identity and steering users to the package vendor's service. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.2.4 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installation mutates the installed DeepSeek Harness UI and branding without a user command. Runtime configuration redirects the harness to Token Harbor and disables upstream provider plugins. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-14T15:53:12.714Z - **Finished:** 2026-08-14T15:53:56.524Z - **Download time:** 507 ms - **Static scan time:** 112 ms - **AI review time:** 43190 ms - **Total time:** 43810 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation mutates the installed DeepSeek Harness UI and branding without a user command. Runtime configuration redirects the harness to Token Harbor and disables upstream provider plugins. - **Trigger:** npm postinstall; later execution of halyard - **Impact:** The installed AI harness is visually and operationally altered, obscuring its upstream identity and steering users to the package vendor's service. - **Evidence paths:** package.json, bin/rebrand.mjs, profile/halyard.patch.yml, bin/auth.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-14T15:53:56.524Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall dependency rebranding and agent-provider takeover - **Attack narrative:** On npm installation, the package runs a script that traverses installed @deepseek-ai dependency lib/dist trees and overwrites matching UI text, replaces the frontend favicon, and injects CSS to hide upstream branding. Its runtime overlay sets Token Harbor as the default model provider and disables upstream provider plugins, creating an unconsented takeover of a foreign AI-agent harness rather than a self-contained wrapper. - **Rationale:** This is concrete install-time mutation of a foreign AI-agent control surface, coupled with routing users to the package vendor's provider. The authentication network traffic is package-aligned but does not mitigate the install-time takeover. - **Files touched:** bin/rebrand.mjs, profile/halyard.patch.yml, node\_modules/@deepseek-ai/dsh-web-frontend/dist/favicon.svg - **Network endpoints:** https://tokenharbor.ai/v1, https://tokenharbor.ai/api/cli/auth/init ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall executes a rebranding script., Install script recursively overwrites text files in installed @deepseek-ai dependencies., Install script replaces the upstream frontend favicon and injects branding CSS., Overlay redirects the harness to Token Harbor and disables upstream provider plugins. - **Evidence against:** Credential and browser-login requests are user-invoked runtime behavior., No source evidence of arbitrary remote payload execution or unrelated credential harvesting. ## Public findings ### 1.
