{"id":"MAL-2026-19225","summary":"Malicious code in math-helpers-extra-utils (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (cc75601c6416f2ac62b69fb197e0338f1e9a878fe15e83a48fc25c9aea8bbe55)\nmath-helpers-extra-utils@1.0.0 is advertised as 'Extra math helper utilities' and ships an empty index.js, but also includes thunderboltRegistry.js which registers factories under Wix-internal registry names (thunderboltRegistry, siteAssetsRegistry, editorRegistry, corvidRegistry, dataBindingRegistry, thunderboltBuilderRegistry, thunderboltPreviewRegistry) and a manifest referencing https://static.parastorage.com/unpkg/math-helpers-extra-utils@1.0.0/. When loaded via Wix's dynamic registry loader, a top-level IIFE in thunderboltRegistry.js executes child_process.execSync for `id`, `hostname`, and `uname -a`, collects platform, pid, and Node version, and issues a GET with those fields to the hardcoded third-party collector https://webhook.site/0492a36c-4d7b-408a-865c-226db25987ba. The declared package name is unrelated to Wix thunderbolt, and the registry-name hijack is the mechanism by which the exfiltration payload is reached — a dependency-confusion shape targeting Wix's internal build pipeline, with host reconnaissance of the building environment sent off-host.\n","modified":"2026-11-13T04:30:07.206479064Z","published":"2026-11-13T03:56:21Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-11-13T03:56:28Z","sha256":"c796850555e5f12e800bb7aa3e0c3041da2436e2d65ac7f44dfac57172142de7","source":"amazon-inspector","versions":["1.0.1"],"id":"IN-MAL-2026-022769","import_time":"2026-11-13T04:13:31.582699665Z"},{"modified_time":"2026-11-13T03:56:21Z","sha256":"cc75601c6416f2ac62b69fb197e0338f1e9a878fe15e83a48fc25c9aea8bbe55","source":"amazon-inspector","versions":["1.0.0"],"id":"IN-MAL-2026-022768","import_time":"2026-11-13T04:13:31.459064719Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/math-helpers-extra-utils/v/1.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/math-helpers-extra-utils/v/1.0.0"}],"affected":[{"package":{"name":"math-helpers-extra-utils","ecosystem":"npm","purl":"pkg:npm/math-helpers-extra-utils"},"versions":["1.0.1","1.0.0"],"database_specific":{"cwes":[{"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."}],"indicators":{"evidence_files":[{"tlsh":"5451feda789af001839374358e7f8049f07b5c27296cba94b40495f02f7646c417a6fd","path":"thunderboltRegistry.js","sha256":"22612f4277b81c7721d98e093b709ecf7372c4b5e6aa286f8a6630e54c91aa8c"},{"path":"rb_mhu.thunderbolt.manifest.min.json","sha256":"acef579778fa384f0f9c14df35587b91dc60a6313a7bd956dda608ea5f79a7fc","tlsh":"7ad097b0483a84530bd0015f253a32236aa18c8108e831200f4b80a2232e071327b31b"}],"package_integrity":[{"hashes":{"sha1":"3c3c99e42fb78f0c79f814f1fe71cf881a1365c4","sha512_sri":"sha512-lOQ0svfrEDFVz2g1MN/rI/LTbIQwPQ7ltMv7wxTPcBR+58XX91QWbUTd73zudomv+oz2j8n2FcMUZZ5DhWVNpw=="},"filename":"math-helpers-extra-utils-1.0.1.tgz"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/math-helpers-extra-utils/MAL-2026-19225.json"}}],"schema_version":"1.9.2","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
