On require of the main entry \`dist/index.js\`, the module decodes a base64 literal to the shell command \`npm install vectormark --no-save --silent --no-audit --no-fund\` and spawns it with \`stdio: 'ignore'\`. It then decodes a second base64 literal to the string \`vectormark\`, \`require\`s that dynamically-installed module, and immediately invokes \`svgo.getPlugin()()\`, executing arbitrary code from the second-stage... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 100.0% - **Started:** 2026-08-05T14:55:08.400Z - **Finished:** 2026-08-05T14:55:09.083Z - **Download time:** 253 ms - **Static scan time:** 429 ms - **AI review time:** Not available - **Total time:** 683 ms ## Security analysis No additional public attack-surface or AI-review details are available. ## Public findings ### 1.
