Compromises dependency integrity and deceptively rebrands a foreign AI-agent control surface. - **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:** 0.2.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm installation, the package mutates the installed DeepSeek AI harness rather than only its own files. It recursively changes upstream server/UI artifacts and replaces the upstream web favicon. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-14T14:42:17.146Z - **Finished:** 2026-08-14T14:43:06.543Z - **Download time:** 520 ms - **Static scan time:** 79 ms - **AI review time:** 48797 ms - **Total time:** 49397 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm installation, the package mutates the installed DeepSeek AI harness rather than only its own files. It recursively changes upstream server/UI artifacts and replaces the upstream web favicon. - **Trigger:** npm postinstall - **Impact:** Compromises dependency integrity and deceptively rebrands a foreign AI-agent control surface. - **Evidence paths:** package.json, bin/rebrand.mjs, bin/auth.mjs, bin/daemon.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-14T14:43:06.543Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Recursive postinstall rewrite of a foreign AI-agent dependency - **Attack narrative:** Installing the package silently runs bin/rebrand.mjs. That script searches for @deepseek-ai dependencies in node\_modules, recursively rewrites their lib and dist files, and replaces the dsh-web-frontend favicon with this package's asset. This alters a separately supplied AI-agent harness outside the package's ownership and hides its identity/integrity from users. - **Rationale:** The concrete postinstall mutation of a foreign AI-agent dependency meets the install-control-surface block boundary. Network and credential code is package-aligned, but does not mitigate the unconsented dependency rewrite. - **Files touched:** package.json, bin/rebrand.mjs, node\_modules/@deepseek-ai/dsh-web-frontend/dist/favicon.svg - **Network endpoints:** https://tokenharbor.ai, https://registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Install hook executes a rebranding script., The hook locates foreign @deepseek-ai packages up to six parent directories., It recursively rewrites installed lib/dist files and replaces the upstream frontend favicon. - **Evidence against:** No credential harvesting or unrelated exfiltration was found; authentication requests are user-invoked., The runtime service and model endpoint are package-aligned. ## Public findings ### 1.
