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. An automatic install hook contains an opaque staged payload. It decompresses hidden data, writes generated content, and starts a child process during installation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-28T06:06:06.269Z - **Finished:** 2026-09-28T06:06:48.710Z - **Download time:** 260 ms - **Static scan time:** 171 ms - **AI review time:** 42009 ms - **Total time:** 42441 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:** An automatic install hook contains an opaque staged payload. It decompresses hidden data, writes generated content, and starts a child process during installation. - **Trigger:** npm preinstall execution. - **Impact:** Installing the package can execute concealed code and modify the consumer environment before the package is used. - **Evidence paths:** package.json, preinstall.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-28T06:06:48.710Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated code dynamically loads system modules, decompresses embedded data, writes it to a generated path, and invokes a child-process function. - **Attack narrative:** The package causes npm to run a very large obfuscated preinstall script. That script hides its operational strings, decompresses an embedded payload, writes generated content, and launches a child process. This is concealed install-time execution with filesystem mutation and command execution, independent of the advertised API client. - **Rationale:** The automatic lifecycle hook combines deliberate obfuscation, staged payload handling, filesystem writes, and process execution. This meets the install-hook abuse boundary for blocking publication. ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package registers an automatic preinstall hook that runs preinstall.cjs., The preinstall file is a large, deliberately obfuscated Function payload that dynamically obtains module loading., The hook loads file, path, compression, and child-process modules, decompresses data, writes a generated file, and launches a child process. - **Evidence against:** The exported client uses a caller-supplied API key and base URL for ordinary API requests. ## Affected versions and remediation This report applies to api-nebula@1.0.0. - Avoid installing api-nebula@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.
