Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. A hidden payload is extracted from a bundled JPEG and executed as an encoded PowerShell command. No user action beyond importing the package or starting its CLI is required. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-21T10:35:42.888Z - **Finished:** 2026-09-21T10:45:42.055Z - **Download time:** 510 ms - **Static scan time:** 138 ms - **AI review time:** 598517 ms - **Total time:** 599167 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A hidden payload is extracted from a bundled JPEG and executed as an encoded PowerShell command. No user action beyond importing the package or starting its CLI is required. - **Trigger:** Importing the CJS package entrypoint or running the dot2env CLI. - **Impact:** On Windows, package import or CLI use can run an opaque embedded PowerShell payload without the caller's consent. - **Evidence paths:** package.json, dist/decode.js, dist/index.cjs, dist/cli.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-21T10:45:42.055Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The dispatcher reads dist/stest.jpg, builds a PowerShell EncodedCommand invocation, writes a temporary self-deleting VBScript, and starts wscript detached with its window hidden. - **Attack narrative:** The package embeds executable content in a JPEG, extracts it at runtime, and launches it through a hidden detached VBScript. Both the library entrypoint and CLI call the dispatcher automatically, making this an import-time and CLI-start payload execution path. - **Rationale:** This is concrete concealed code execution, not environment configuration behavior. The automatic entrypoint calls and hidden encoded PowerShell launcher warrant blocking publication. - **Files touched:** package.json, dist/decode.js, dist/stest.jpg, dist/index.cjs, dist/cli.cjs ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest exposes the bundled CJS module as the package entrypoint and the bundled CLI as an executable., Code reads a payload from a JPEG file located beside the module., The payload is assembled into a PowerShell command with the EncodedCommand switch., The code writes a self-deleting VBScript that launches the command hidden and detached., The CJS library invokes the payload dispatcher during module initialization., The CLI also invokes the payload dispatcher before processing its normal command logic. ## Affected versions and remediation This report applies to better-envforge@1.0.0. - Avoid installing better-envforge@1.0.0. 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.
