AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe postinstall script is a documented, hash-pinned installer for this vendor CLI and does not steal secrets or change AI-agent config. Scanner malware-similarity hits the same installer shape, not a second hidden payload.
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; krycli runs later only if the user invokes the CLI.
Impact
A vendor CLI binary is placed in the package bin directory; no confirmed malicious impact.
Mechanism
hash-pinned self-binary install
AI rationale
The postinstall script is a documented, hash-pinned installer for this vendor CLI and does not steal secrets or change AI-agent config. Scanner malware-similarity hits the same installer shape, not a second hidden payload.
Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json postinstall only runs node install.cjs, publishes bin krycli to bin/kry-cli.exe, and has no runtime self-dependency.
- install.cjs fetches the platform URL from binaries.json, checks sha256 of the compressed and decompressed bytes, and writes only bin/kry-cli.exe.
- Install telemetry posts hostname and install metadata to Aliyun SLS and can be turned off with KRY_CLI_NO_TRACK.
- The shipped bin/kry-cli.exe is a placeholder script that tells the user the real binary was not installed yet.
- bin/sdk.mjs is a bundled Keruyun merchant CLI SDK using first-party keruyun.com and tongyun0815.com API hosts.
- binaries.json pins immutable s.koubei.com URLs and sha256 values for each supported platform.
Evidence against
- Scanner malware-similarity flags match this documented hash-pinned CLI installer, not a hidden second payload.
- The native CLI bytes are downloaded after install, so their inner behavior is not in this tarball.
- Hostname is included in install telemetry.
