This behavior is unrelated to a Rollup polyfill plugin. - **Trigger:** Any runtime require/import resolution using package.json main (dist/index.js). - **Impact:** Unconsented dependency installation and remote code execution in the consumer environment. - **Evidence paths:** package.json, dist/index.js, dist/es/index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-24T12:35:45.658Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated child-process npm install followed by dynamic plugin execution. - **Attack narrative:** When the CommonJS package entrypoint is loaded, it decodes an npm command and spawns a silent install of \`ambera\` without saving it. On completion, it dynamically loads that newly fetched package, obtains a plugin, and invokes it. The fetched dependency is not declared in package.json, and the base64 encoding conceals both the command and module name. - **Rationale:** The entrypoint contains a concrete, obfuscated import-time chain that installs and executes an undeclared remote package. No lifecycle hook is needed for this behavior to affect consumers that load the CommonJS entrypoint. - **Files touched:** dist/index.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** dist/index.js decodes and spawns \`npm install ambera --no-save --silent --no-audit --no-fund\`., dist/index.js invokes ValidateSvgModule() at CommonJS import time., After installation it dynamically requires \`ambera\` and calls its getPlugin() result., The install command and module name are base64-obfuscated., package.json exposes dist/index.js as the main entrypoint. - **Evidence against:** package.json has no npm lifecycle hook., dist/es/index.js lacks the injected installer code. ## Public findings ### 1.
