AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe postinstall hook is a readable Keruyun CLI installer that downloads hash-pinned binaries from s.koubei.com into this package's own bin path and optionally reports install metrics to Aliyun SLS. Scanner malware-fingerprint and native-binary labels are noisy: the tarball kry-cli.exe is a placeholder stub, and there is no foreign agent-config write, secret harvest, or self-dependency chain.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
npm install runs postinstall; the krycli binary and SDK run only after that install or an explicit import.
Impact
No confirmed credential theft, foreign agent hijack, or consumer-project mutation.
Mechanism
hash-pinned CDN binary install plus optional install telemetry
AI rationale
The postinstall hook is a readable Keruyun CLI installer that downloads hash-pinned binaries from s.koubei.com into this package's own bin path and optionally reports install metrics to Aliyun SLS. Scanner malware-fingerprint and native-binary labels are noisy: the tarball kry-cli.exe is a placeholder stub, and there is no foreign agent-config write, secret harvest, or self-dependency chain.
Decision evidence
public snapshotAI called this Clean at 86.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- postinstall runs node install.cjs, which fetches a remote brotli binary and overwrites this package's bin/kry-cli.exe
- install telemetry POSTs hostname, npm metadata, AGENT_WORK_ROOT user id, and REWIND_SESSION_ID to Aliyun SLS
- sdk.mjs is a large minified bundle, and scanners flagged installer similarity to a previously blocked package
Evidence against
- CDN URLs and sha256 hashes are pinned in binaries.json; the installer writes only bin/kry-cli.exe inside this package after verifying both the compressed and decompressed bytes
- the shipped bin/kry-cli.exe is a text placeholder stub, not a native implant
- network hosts are Keruyun, Koubei, and Aliyun product endpoints; telemetry is opt-out via KRY_CLI_NO_TRACK
- no foreign AI-agent config writes, no secret-file harvest, no runtime self-dependency, and no obfuscated install script
