Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The Windows native addon automatically executes decoded content from .napi\_cache when the package is imported, behavior unrelated to the stated event-dispatcher purpose. The staged program itself is unreadable here, so the evidence supports a warning for an automatic payload carrier rather than a definitive malware finding. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-31T03:29:47.191Z - **Finished:** 2026-10-31T03:30:45.661Z - **Download time:** 257 ms - **Static scan time:** 9 ms - **AI review time:** 58203 ms - **Total time:** 58470 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 automatically loaded Windows native addon stages and launches decoded content whose purpose is not established. - **Trigger:** Importing the package on Windows. - **Impact:** The staged program can execute automatically with the importing process's privileges; its behavior is unknown. - **Evidence paths:** index.js, .napi\_cache, native\_win.node, .lpm-inspection-kWG3wG/1-8392fb2fbf79.txt, .lpm-inspection-kWG3wG/0-603b601b47d5.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-31T03:30:45.661Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The addon reads .napi\_cache, XOR-transforms the bytes, writes them under the Windows temporary directory, and invokes CreateProcessA. - **Rationale:** The Windows native addon automatically executes decoded content from .napi\_cache when the package is imported, behavior unrelated to the stated event-dispatcher purpose. The staged program itself is unreadable here, so the evidence supports a warning for an automatic payload carrier rather than a definitive malware finding. - **Files touched:** .napi\_cache, Windows temporary directory (PID-based path) ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** Importing index.js immediately loads a platform-specific native addon., The Windows addon refers to a .napi\_cache file., The Windows addon reads the cache file and XOR-transforms its contents., The Windows addon writes decoded bytes to a temporary file and calls CreateProcessA. - **Evidence against:** The package is described as a lightweight event dispatcher and exports a small EventBus implementation., package.json declares no lifecycle scripts or dependencies., The Windows analysis does not show a network API import; the Linux native artifact remains unanalyzed. ## Affected versions and remediation This report applies to evt-dispatcher@1.0.5. - Review the evidence and your use of evt-dispatcher@1.0.5 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
