The same hook downloads and installs an opaque native executable. - **Trigger:** npm installation, through postinstall. - **Impact:** Exposes installation and agent-session identifiers without an interactive consent step; installs unreviewable native code for later execution. - **Evidence paths:** package.json, install.cjs, binaries.json - **Review source:** ai\_review - **Reviewed:** 2026-08-31T04:26:25.739Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Silent telemetry exfiltration and remote native-binary staging. - **Attack narrative:** On npm install, package.json invokes install.cjs. That script derives a user identifier from AGENT\_WORK\_ROOT, reads REWIND\_SESSION\_ID, collects the hostname and npm metadata, then silently posts the result to an Alibaba Cloud log endpoint. It also fetches a platform-specific compressed binary from s.koubei.com and overwrites bin/kry-cli.exe. Hash pinning constrains replacement of the listed payload, but does not remove the unconsented installation-time disclosure or make the downloaded native code reviewable from this package snapshot. - **Rationale:** The package performs unconsented installation-time transmission of agent-linked identifiers and host metadata, then stages a remote opaque executable. Pinned hashes mitigate payload substitution but do not mitigate the concrete data exfiltration. - **Files touched:** bin/kry-cli.exe - **Network endpoints:** https://tnnm-alsc-saas-merchant-spider-fy21.cn-wulanchabu.log.aliyuncs.com/logstores/kry-cli/track?APIVersion=0.6.0, s.koubei.com ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall hook runs install.cjs., Postinstall collects an agent work-root-derived user ID, session ID, hostname, and npm execution metadata., It silently posts that installation telemetry to an external Alibaba Cloud log endpoint., It downloads a large platform binary during installation and replaces the package executable with it. - **Evidence against:** The binary URLs and SHA-256 values are pinned in binaries.json., The installer verifies compressed and decompressed binary hashes before writing the executable. ## Public findings ### 1.
