On macOS it downloads and executes apex-helper-darwin without integrity verification; failed binary-hash verification is non-fatal. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-07-22T15:30:34.461Z - **Finished:** 2026-07-22T15:31:11.593Z - **Download time:** 509 ms - **Static scan time:** 36 ms - **AI review time:** 36587 ms - **Total time:** 37132 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall downloads platform binaries. On macOS it downloads and executes apex-helper-darwin without integrity verification; failed binary-hash verification is non-fatal. - **Trigger:** npm install (postinstall); --mcp-stdio for runtime npx fallback - **Impact:** A compromised or substituted release asset can execute code with the installing user's privileges. - **Evidence paths:** package.json, install.cjs, apex.cjs, README.md, bin/apex - **Review source:** ai\_review - **Reviewed:** 2026-07-22T15:31:11.593Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote binary download and execution - **Rationale:** The package contains an unsafe remote executable loader at install time, but no inspected source establishes credential theft, destructive behavior, or AI-agent configuration hijacking. Treat as a critical vulnerability requiring warning rather than a confirmed malicious package. - **Files touched:** install.cjs, bin/apex, bin/apex.sha256, ~/.apex/apex-helper, ~/.apex/natives/16.3.6/pi\_natives.win32-x64-baseline.node - **Network endpoints:** https://github.com/Apex-Foundation/copilot/releases/download/v1.0.0/apex-helper-darwin, https://github.com/Apex-Foundation/copilot/releases/download/v1.0.0/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for:** package.json runs install.cjs as postinstall., install.cjs downloads and executes an unverified macOS helper during install., Hash-download failure only warns, leaving the downloaded executable in place., apex.cjs runs npx -y @apexfdn/copilot-mcp in explicit MCP mode. - **Evidence against:** No source reads credentials or exfiltrates local data., README.md only documents MCP configuration; package code does not modify agent configs., Network URLs are fixed GitHub release URLs, not attacker-supplied input. ## 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 install.cjs ``` ### 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.

High: Runtime Package Install - **Category:** Source - **Confidence:** 86.0% - **Path:** apex.cjs - **Public source:** [View source]() Package source invokes a package manager install command at runtime. Public source snippet (untrusted): ```javascript L15: } catch { L16: const result = spawnSync('npx', ['-y', '@apexfdn/copilot-mcp'], { L17: stdio: 'inherit', ``` ### 9. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 10. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 80.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 11. Critical: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** install.cjs - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = @copilot-mcp/apex@1.0.16 matchedIdentity = npm:QGNvcGlsb3QtbWNwL2FwZXg:1.0.16 similarity = 0.500 summary = stored previous version shares package body but lacks this dangerous source file ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @copilot-mcp/apex - **Ecosystem:** npm - **Version:** 1.0.18 - **License:** MIT - **Version published:** 2026-07-22T15:27:56.910Z - **Package first seen:** 2026-07-22T15:31:11.593Z - **Package last seen:** 2026-08-05T14:00:09.662Z - **Known versions:** 14 - **Latest version:** 1.0.19 - **Appeal under review:** No ## References - [HTML security report]()
