Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package runs an obfuscated downloader that obtains and loads a native payload without an integrity check. It also runs a rebuild command with lifecycle scripts enabled. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-12T09:53:13.213Z - **Finished:** 2026-09-12T09:54:09.190Z - **Download time:** 512 ms - **Static scan time:** 1035 ms - **AI review time:** 54428 ms - **Total time:** 55977 ms The recorded confidence comes from the underlying analysis.

It also runs a rebuild command with lifecycle scripts enabled. - **Trigger:** npm installation - **Impact:** A package-controlled remote host can supply native code that executes during installation. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T09:54:09.190Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated install-time remote native payload download and execution - **Attack narrative:** The package registers postinstall, which runs an intentionally obfuscated script. That script fetches a better-sqlite3 archive from the vendor OSS endpoint, writes extracted files under node\_modules, and validates them by loading the module in a child Node process. Because the download has no visible integrity verification, the remote host controls native code executed during package installation; the script additionally runs npm rebuild with foreground lifecycle scripts. - **Rationale:** This is an automatic, obfuscated install hook that downloads and executes unverified native code from a remote host. Its dependency-repair purpose does not remove the install-time remote-code-execution risk. - **Files touched:** package.json, postinstall.js, node\_modules/better-sqlite3, node\_modules/better-sqlite3/prebuilds - **Network endpoints:** bd-acw.oss-cn-beijing.aliyuncs.com ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Installation automatically runs an obfuscated postinstall program., The postinstall code downloads a native archive from a vendor-controlled OSS host, extracts it into better-sqlite3, then loads it with Node., The install hook also invokes npm rebuild with foreground scripts, allowing further lifecycle execution. - **Evidence against:** No runtime self-dependency is declared., The downloaded artifact is named as a better-sqlite3 prebuild, consistent with the package's optional SQLite dependency. ## Affected versions and remediation This report applies to @bangdao-ai/acw-tools@1.13.73. - Avoid installing @bangdao-ai/acw-tools@1.13.73. 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.
