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:** external-osv-malicious-v1 - **Verdict:** Malicious - **Confidence:** 100.0% - **Started:** 2026-08-23T03:40:05.646Z - **Finished:** 2026-08-23T03:40:05.646Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available ## Security analysis No additional public attack-surface or AI-review details are available. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% 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 package. The install target is unpinned and installed with \`--no-save\`, so the dropped code is not recorded in the consumer's lockfile. Both the shell command and the target module name are stored as base64 strings (\`Buffer.from(..., 'base64').toString('utf8')\`) to hide them from static review. The package name \`rollup-packages-polyfill-core\` typosquats the legitimate \`rollup-plugin-polyfill-node\`, whose repository it also declares. \#\# Source: ghsa-malware (9b4d6b267c6acf02bfba1366c8d1fe3e3285f2fd492a34d2c499e33d7d2efcff) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** rollup-packages-polyfill-core - **Ecosystem:** npm - **Version:** 0.13.5 - **Version published:** 2026-06-05T16:15:04.553Z - **Package first seen:** 2026-07-10T17:30:20.244Z - **Package last seen:** 2026-08-23T03:40:05.646Z - **Known versions:** 9 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
