It extracts and installs the archive's executable and asset directories. - **Trigger:** Installing the npm package when its platform package is absent. - **Impact:** A network attacker or endpoint compromise can supply a replacement native executable that runs when the user invokes onecode. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-08-09T22:32:47.310Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** insecure remote native-payload download and installation - **Rationale:** The package has a concrete install-time insecure native payload chain, but source inspection does not establish malicious intent or a completed malicious payload. It should be warned as a critical vulnerability rather than blocked as malware. - **Files touched:** .platform-bootstrap-work/, node\_modules/onecode-linux-x64/, bin/.onecode, .platform-version, .opencode/, .oneskills/ - **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz ### Review decision - **Verdict:** Suspicious - **Confidence:** 98.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall.mjs during npm install., platform-bootstrap.mjs downloads a platform archive from https://218.90.133.98:4443/onecode\_tgz., HTTPS download explicitly sets rejectUnauthorized: false., Downloaded archive is extracted with tar and its native binary is installed into node\_modules., postinstall links downloaded .opencode and .oneskills directories into the package root. - **Evidence against:** The inspected JavaScript contains no credential harvesting or exfiltration., The launcher only executes the installed binary after an explicit onecode command., No source evidence of deletion outside its own package/install paths. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node ./postinstall.mjs ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node ./postinstall.mjs ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 5. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 6. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 7. High: Unverified Remote Native Payload Install - **Category:** Source - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() Install-time source downloads a native archive from a fixed external host without transport verification, extracts it, and installs an executable payload. Public source snippet (untrusted): ```json scripts.postinstall = node ./postinstall.mjs Install-time code downloads an unverified remote native archive, stages it locally, activates an executable path, and exposes it to process execution.

L99: return new Promise((resolve, reject) => { ``` ### 8. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 9. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** platform-bootstrap.mjs - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review.
