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. npm postinstall runs an installer that mutates the consumer OpenCode control surface and then fetches a remote signed bundle into the same agent and command directories. That is unconsented install-time hijack of a foreign agent runtime, with network-served files as the thin-package payload. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-18T19:21:12.045Z - **Finished:** 2026-09-18T19:23:16.912Z - **Download time:** 513 ms - **Static scan time:** 161 ms - **AI review time:** 124192 ms - **Total time:** 124867 ms The recorded confidence comes from the underlying analysis.

That is unconsented install-time hijack of a foreign agent runtime, with network-served files as the thin-package payload. - **Trigger:** npm install of @tera-system/pro, which runs the postinstall script node scripts/install.js - **Impact:** OpenCode in the consumer project can load package- and server-supplied agents, commands, and MCP config without a separate user setup command - **Evidence paths:** package.json, scripts/install.js, scripts/lib/bundle.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-18T19:23:16.912Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented postinstall write of OpenCode agents, commands, and config, plus remote bundle apply - **Attack narrative:** On npm install, postinstall runs scripts/install.js against the consumer workspace. It seeds OpenCode agent and command directories and, if missing, writes .opencode/opencode.json from a bundled MCP template. In thin mode it then fetches a signed bundle from teranoo.com and applyBundle writes those files into .opencode/agents and .opencode/commands without the ownership checks used for local copies. That is unconsented install-time mutation of a foreign OpenCode control surface, with a remote payload as the content source. - **Rationale:** The postinstall hook mutates a foreign OpenCode control surface in the consumer project and then applies a remotely fetched bundle into the same agent and command paths. That matches unconsented install-time AI-agent control hijack and is not saved by README text or local ownership checks. - **Files touched:** .opencode/agents, .opencode/commands, .opencode/opencode.json, .opencode/tera.manifest.json, .tera/license.state.json, .tera/sync.state.json, tera-system/, tools/, project-control/, scripts/ - **Network endpoints:** https://teranoo.com/api/tera-system/bundle, https://teranoo.com/api/license ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** postinstall automatically runs scripts/install.js against the consumer workspace (INIT\_CWD or cwd)., The installer copies agents and commands into the consumer .opencode directory., If missing, it writes .opencode/opencode.json from the bundled MCP template., After local copies, it downloads a signed bundle from teranoo.com and applyBundle writes those files into .opencode/agents and .opencode/commands., applyBundle writes bundle files with no ownership check, despite comments claiming otherwise., This is a thin package with no local agents directory, so install-time network content is the OpenCode payload. - **Evidence against:** Local installGroup skips unowned differing files and backs up owned updates., Existing consumer opencode.json is not overwritten., Remote files are Ed25519-signed before apply., No Cursor, Claude, or Copilot config writes were found., README describes the OpenCode layout, which does not grant install-time consent. ## Affected versions and remediation This report applies to @tera-system/pro@0.2.26. - Avoid installing @tera-system/pro@0.2.26. 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.
