The HTML mimics a Cloudflare 'Just a moment...' challenge and contains obfuscator.io-style control-flow-obfuscated JavaScript that constructs a redirect URL from a rotated string array and calls window.location.replace(targetUrl). There are no lifecycle scripts (preinstall/install/postinstall/prepare) and `main` pointing at an HTML file means `require()` cannot load it, so nothing runs on `npm install` or on import in a Node.js developer/build environment. The harmful behavior only fires when the HTML is fetched by a browser via an npm-backed CDN (unpkg/jsdelivr) and rendered — i.e., abuse of the npm registry as a hosting/CDN for a phishing or malvertising redirect page targeting browser end-users, not developers who install the package. Under this system's installer-centric threat model, installing or requiring this package produces no exfiltration, no code execution, no credential access, and no persistence on the installer's machine.\n\n## Source: ghsa-malware (0ec0ff2d2bfc91e5432374bb1673cdb2a9de424bcfc1474052593f16607d6320)\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":"csbcldfvivwfgd4","ecosystem":"npm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["1.0.0"],"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"}],"indicators":{"evidence_files":[{"path":"index.html","sha256":"a61892f2cd9e041d3ed9e5937dbb97e88b91c034e1a66081fe958f873ae7a001","tlsh":"dbd2939163c03c51120b9f72771fe2e1e52d1ae97688048bf14cbe98efe9649dbd0a70"}]}}}],"references":[{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-5pjw-x44v-j286"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/csbcldfvivwfgd4/v/1.0.0"}],"database_specific":{"malicious-packages-origins":[{"id":"GHSA-5pjw-x44v-j286","import_time":"2026-08-12T10:39:02.375831715Z","modified_time":"2026-08-12T10:29:53Z","ranges":[{"events":[{"introduced":"0"}],"type":"SEMVER"}],"sha256":"0ec0ff2d2bfc91e5432374bb1673cdb2a9de424bcfc1474052593f16607d6320","source":"ghsa-malware"},{"id":"IN-MAL-2026-017534","import_time":"2026-08-12T12:51:48.459104313Z","modified_time":"2026-08-12T12:35:04Z","sha256":"f6d7db017a0499c0fca67cc331c44fa736fe52568177990823cb17bd03ceee21","source":"amazon-inspector","versions":["1.0.0"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
