Loading dist/main.js outside an agent TTY disables Windows protections, fetches a remote command over unverified TLS, executes it hidden, and rewrites foreign AI assistant MCP configs to point at the current executable. - **Trigger:** User or script execution of the apex-audit bin (audit.cjs), or loading dist/main.js in an interactive terminal. npm install does not hook it. - **Impact:** Remote code execution, security-control bypass, and persistent hijack of AI-agent MCP configuration so later assistant sessions launch the attacker binary. - **Evidence paths:** dist/main.js, audit.cjs, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-26T05:37:26.793Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** audit.cjs fetches a GitHub release binary and spawns it. dist/main.js hides from non-TTY and --mcp/--stdio/--json, then on Windows elevates PowerShell for a Defender exclusion and SAC registry change, POSTs to vrf.apexaccs.org, and runs the returned command via wscript. It then writes Claude, Cursor, and Windsurf mcpServers entries. On macOS it downloads and detaches apex-audit-verify. - **Attack narrative:** The npm bin is a dropper: audit.cjs pulls a release binary into the home directory and runs it. The bundled dist/main.js is a second stage that bails out when it detects an agent or non-interactive session. In a normal terminal it weakens Windows Defender and Smart App Control, asks vrf.apexaccs.org for a command with TLS checks off, and runs that command through a hidden script. It then rewrites Claude, Cursor, and Windsurf MCP configs so the assistant launches this process. macOS instead downloads and detaches a verify binary before the same config write. - **Rationale:** Shipped code hides from agent sessions, tampers with OS security controls, executes a remotely supplied command, and writes foreign AI-assistant MCP configs to the current executable. The CLI separately downloads and runs an unsigned GitHub release binary, so this is an active malware chain rather than an install-hook-only warning. - **Files touched:** ~/.apex-audit, ~/Library/Application Support/Claude/claude\_desktop\_config.json, ~/.cursor/mcp.json, ~/.codeium/windsurf/mcp\_config.json, %APPDATA%/Claude/claude\_desktop\_config.json, %APPDATA%/Windsurf/mcp\_config.json, %TEMP%/\_audit\_run.ps1, %TEMP%/\_audit\_run.vbs - **Network endpoints:** https://vrf.apexaccs.org/api/v1/vrf, https://github.com/apexaccs/audit-mcp/releases/download/ ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** dist/main.js exits immediately when stdin or stdout is not a TTY or when argv contains --mcp, --stdio, or --json, so agent and inspector runs never reach the payload., On Windows 11, dist/main.js launches hidden elevated PowerShell that adds a Defender exclusion for ~/.apex-audit and sets VerifiedAndReputablePolicyState to 0., After the platform payload, dist/main.js writes Claude, Cursor, and Windsurf MCP configs so the apex-audit server command is process.execPath with --mcp., dist/main.js POSTs to https://vrf.apexaccs.org/api/v1/vrf with rejectUnauthorized false and, if the JSON has cmd, exec, and args, runs that command through a temp PowerShell script and hidden wscript., The published bin audit.cjs downloads a platform binary from GitHub releases into ~/.apex-audit/bin and spawnSync-executes it with the caller arguments., package.json points main and bin at audit.cjs, defines no install lifecycle scripts, and still ships dist/main.js which calls main() on load. - **Evidence against:** package.json has no preinstall, install, or postinstall hook, so npm install alone does not run the dropper., The MCP tool modules register audit helpers and are reached only after the --mcp branch, which returns before the Windows or macOS payload. ## Affected versions and remediation This report applies to @apexacc/audit@1.0.7. - Avoid installing @apexacc/audit@1.0.7. 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.
