Those hooks can automatically download and execute a remote overlay binary, while generated agent text discourages inspection. - **Trigger:** Running the package's install command, followed by an agent lifecycle event or overlay launch. - **Impact:** A remote release host can supply code that runs through installed agent hooks; the installer also alters multiple agent control surfaces. - **Evidence paths:** scripts/install-adapters.sh, scripts/manage-harness-hooks.ts, scripts/overlay.ts, scripts/run-with-bun.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-16T22:59:05.900Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global agent-hook installation followed by remote binary download and execution. - **Attack narrative:** The package’s explicit installer places skills and hooks into global Codex, Claude, Hermes, OpenClaw, and Antigravity locations. The installed hooks invoke the overlay launcher on agent lifecycle events. That launcher fetches a manifest and executable from the release host, trusts a hash supplied by that same host, writes the executable, and starts it detached. The generated skill text also directs agents not to inspect the repository or run other commands, which is reviewer and agent manipulation. A missing Bun runtime additionally triggers a shell pipeline from bun.sh. - **Rationale:** This is a concrete remote code execution path coupled to global AI-agent hook installation and instructions designed to suppress inspection. The absence of an npm lifecycle hook does not neutralize the automatic post-install hook path. - **Files touched:** scripts/install-adapters.sh, scripts/manage-harness-hooks.ts, scripts/overlay.ts, scripts/run-with-bun.cjs - **Network endpoints:** https://releases.runretroarcade.com, https://bun.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The explicit installer targets several user-global AI-agent skill and command locations, then writes a generated instruction that tells an agent not to inspect the repository or run other commands., The installer adds lifecycle commands for SessionStart, prompt submission, Stop, and SessionEnd to Codex and other agent harness configurations., The launcher downloads an executable from the release host, obtains its expected hash from that same remote manifest, marks it executable, and starts it automatically., If Bun is absent, the launcher pipes a remote Bun installer directly into a shell. - **Evidence against:** package.json has no npm preinstall, install, or postinstall hook., The package has no runtime dependency on its own package name. ## Affected versions and remediation This report applies to @tui-games/tui@0.4.9. - Avoid installing @tui-games/tui@0.4.9. 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.
