The package becomes enabled across OpenCode projects without an explicit setup command. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.8.4 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Automatic installation modifies the global OpenCode TUI plugin list. Runtime initialization repeats that registration and can create a global package symlink. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T13:34:12.518Z - **Finished:** 2026-09-13T13:35:16.306Z - **Download time:** 501 ms - **Static scan time:** 2433 ms - **AI review time:** 60852 ms - **Total time:** 63788 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:** Automatic installation modifies the global OpenCode TUI plugin list. Runtime initialization repeats that registration and can create a global package symlink. - **Trigger:** npm installation runs postinstall; loading the plugin runs its initialization. - **Impact:** The package becomes enabled across OpenCode projects without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/plugin/index.js, dist/infrastructure/tui-self-register.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T13:35:16.306Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global OpenCode configuration and package-link mutation. - **Attack narrative:** Installing the package automatically runs postinstall, which creates or edits the user's global OpenCode TUI configuration and adds the package as a plugin. If lifecycle scripts are skipped, merely loading the plugin repeats the registration and may create a global node\_modules symlink. This is an unconsented, persistent mutation of a broad AI-agent control surface, causing the package to be activated for OpenCode use beyond the installing project. - **Rationale:** This package has a concrete automatic postinstall path that mutates a global OpenCode control surface, and an import-time self-healing path that repeats it. That meets the install-control-surface block boundary despite no evidence of credential exfiltration. - **Files touched:** ~/.config/opencode/tui.json, ~/.config/opencode/node\_modules/opencode-fractal-memory ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook runs automatically after installation., Postinstall adds this package to the user's global OpenCode TUI configuration., Plugin initialization repeats the global TUI registration and may create a global node\_modules link., The mutation loads this package into every OpenCode project without an explicit user command. - **Evidence against:** No credential harvesting or outbound exfiltration was found., The observed network code targets local Ollama services or model downloads, not a secret collection endpoint., The large GLB file is a valid glTF brain model, not an executable payload. ## Affected versions and remediation This report applies to opencode-fractal-memory@0.8.4. - Avoid installing opencode-fractal-memory@0.8.4. 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.
