The evaluated code cannot be safely determined from the published source. - **Trigger:** Import or load the package's default UMD entrypoint in a browser application. - **Impact:** The bundle can execute arbitrary browser-side code outside the readable SDK implementation. - **Evidence paths:** package.json, dist/index.umd.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T03:06:26.658Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated string construction followed by eval. - **Attack narrative:** The manifest directs default consumers to dist/index.umd.js. That bundle includes opaque, generated-looking control flow that evaluates a computed value with eval. Because the evaluated source is hidden behind the obfuscation and is not represented by the readable ESM implementation, importing the normal entrypoint creates an unreviewable arbitrary-code execution path. - **Rationale:** The UMD entrypoint is intentionally obfuscated and dynamically evaluates generated code. This is concrete opaque runtime execution in the package's normal import path. - **Files touched:** package.json, dist/index.umd.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The default package entrypoint is the UMD bundle., The UMD bundle contains deliberately obfuscated control flow that dynamically evaluates a constructed string. - **Evidence against:** The manifest has no install or lifecycle scripts., The visible ESM authentication code uses named Comein service endpoints, but it does not explain the opaque UMD evaluator. ## Public findings ### 1.
