No integrity pin or signature verification protects that remote payload. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-22T22:26:46.807Z - **Finished:** 2026-08-22T22:27:27.287Z - **Download time:** 759 ms - **Static scan time:** 61 ms - **AI review time:** 39656 ms - **Total time:** 40480 ms ## Security analysis ### Published attack-surface review - **Summary:** At postinstall on Android, the package fetches a mutable upstream native executable and executes it for a smoke test. No integrity pin or signature verification protects that remote payload. - **Trigger:** npm postinstall on Android/Termux, or explicit CLI use when vendor files are absent - **Impact:** A compromised or substituted upstream artifact can run during installation. - **Evidence paths:** package.json, install.mjs, bin/opencode.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T22:27:27.287Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads and executes a mutable upstream native binary - **Rationale:** The reviewed source establishes an install-time unverified remote-native-payload chain but no concrete malicious action. Treat it as a staged payload carrier and warn rather than block. - **Files touched:** package.json, install.mjs, .build, vendor, vendor/opencode, vendor/ld-musl.so - **Network endpoints:** https://registry.npmjs.org/opencode-ai/latest, https://registry.npmjs.org/opencode-linux-${ARCH}-musl/-/opencode-linux-${ARCH}-musl-${V}.tgz, https://dl-cdn.alpinelinux.org/alpine/${AV}/releases/${A}/alpine-minirootfs-${AL}-${A}.tar.gz, https://dl-cdn.alpinelinux.org/alpine/${AV}/main/${A}/${f} ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall automatically runs install.mjs., Installer resolves mutable upstream latest, downloads its native tarball, and later executes it without an integrity check., Installer replaces package-local vendor/ and executes only the downloaded binary with --version. - **Evidence against:** Network destinations are explicit npm registry and Alpine hosts., Source contains no credential harvesting, exfiltration, eval, or AI-agent configuration writes., CLI execution is a Termux loader wrapper; Android bundle installation is platform-gated. ## Public findings ### 1.
