On `require()` of the main entry (`dist/index.js`), a base64-encoded command `npm install cors-update --no-save --silent --no-audit --no-fund` is decoded and passed to `child_process.spawn` with `stdio:'ignore'` and `windowsHide:true`. When the install child exits, the code then base64-decodes the module name `cors-update`, dynamically `require`s it, and invokes `.getPlugin()()`, executing whatever code that separately-published package ships. The command string and the target module name are both stored as base64 literals to evade plain-text scanners. The package's advertised purpose (a Rollup Node polyfills plugin) does not require installing or executing any other npm package at import time.\n\n## Source: ghsa-malware (3c6b3851dc147286bd78055855402bd425ede657b7911d1334158729680b95bf)\nAny 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.\n","affected":[{"package":{"name":"rollup-packages-node-polyfills","ecosystem":"npm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["0.13.2","0.0.1","0.13.1","0.13.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"dist/index.js","sha256":"aab2343549f633386070530996481751975ee796e0f30b52200410b76b730d6b","tlsh":"4e81642514f629550373b6ec518bec71397b9393338ccb503e2c83709fa15288a76af5"}],"package_integrity":[{"filename":"rollup-packages-node-polyfills-0.13.2.tgz","hashes":{"sha1":"4c5c587106a3da76a471981552bc1a01690b8d6f","sha512_sri":"sha512-hfIi7VbhFGD/jlJiC8G4dfw6fxacgKuscdKlCrDX4J/J4L95IFBKBURTcqt0m9Bs1DognX839zpmlECEn1n9sA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/rollup-packages-node-polyfills/v/0.13.2"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/rollup-packages-node-polyfills/v/0.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/rollup-packages-node-polyfills/v/0.13.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/rollup-packages-node-polyfills/v/0.13.0"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-gp6f-mxh4-x3mh"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-014846","import_time":"2026-08-05T13:08:50.752419587Z","modified_time":"2026-08-05T13:00:44Z","sha256":"69acfb561d96b50bad013aee083ca9334855473d17983665b077953853827a20","source":"amazon-inspector","versions":["0.13.2"]},{"id":"IN-MAL-2026-014847","import_time":"2026-08-05T13:08:50.818159326Z","modified_time":"2026-08-05T13:00:51Z","sha256":"8271e51ffa2367b6282e7ed6834cf70ba341d4c56051e3cc1d25acdcaeab3e9f","source":"amazon-inspector","versions":["0.0.1"]},{"id":"IN-MAL-2026-014798","import_time":"2026-08-05T13:08:47.249676232Z","modified_time":"2026-08-05T12:52:52Z","sha256":"dd41e8f4e3846a790a96f518bbdcfe70be2839531c5ea5485924e7fd25603399","source":"amazon-inspector","versions":["0.13.1"]},{"id":"IN-MAL-2026-014649","import_time":"2026-08-05T13:08:33.823108056Z","modified_time":"2026-08-05T12:25:23Z","sha256":"f9f367bb71da1310a9cb108ef4132a9e4455013547561f0de311bd672f5fd230","source":"amazon-inspector","versions":["0.13.0"]},{"id":"GHSA-gp6f-mxh4-x3mh","import_time":"2026-08-21T12:26:03.491181507Z","modified_time":"2026-08-21T12:12:33Z","ranges":[{"events":[{"introduced":"0"}],"type":"SEMVER"}],"sha256":"3c6b3851dc147286bd78055855402bd425ede657b7911d1334158729680b95bf","source":"ghsa-malware"}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
