Its single exported function validated(e) in index.js issues axios.get against a hardcoded destination and appends the caller-supplied argument to the URL, causing whatever the consuming application passes in (EVM addresses, keys, or arbitrary user data) to be transmitted to a remote host the caller never configured. The destination is deliberately hidden: a scrambled string array is joined, ROT13-transformed, and reversed at runtime to reconstruct https://api-ivalidte.vercel.app/app/api/ — a typosquat-shaped Vercel host that does not correspond to any documented service for this package. The obfuscation of the destination combined with the mismatch between the advertised purpose (local validation) and the actual behavior (remote relay to an author-controlled endpoint) is the silent-relay shape.\n","affected":[{"package":{"name":"evm-validation","ecosystem":"npm"},"versions":["1.0.3","1.0.2","1.0.4"],"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"}],"indicators":{"evidence_files":[{"path":"index.js","sha256":"7e8f2f7d89a2be5e706545121edc8362b6ae926842ecfc1dfea25bebd372b90b","tlsh":"8fe0682f3988227b4c71b0e37e9b403958edc744636052e0122c9a6718edd991577f34"}],"package_integrity":[{"filename":"evm-validation-1.0.3.tgz","hashes":{"sha1":"398c4242cc87c9474c58636d005912f3ccb09eda","sha512_sri":"sha512-s57y/HJ1w/nwHnmYwdy/4oCmYJvVeuDYLMjwodhhUNCbzeCXTP0LB+hRMBJn/Rrwh4aOHuB4/0WXLzUgh/qQLg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/evm-validation/v/1.0.3"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/evm-validation/v/1.0.2"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/evm-validation/v/1.0.4"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-018422","import_time":"2026-08-19T10:44:44.76090745Z","modified_time":"2026-08-19T10:14:53Z","sha256":"8b39d83a94d652f10bd7e87a7680ce70d197876379fcaf6de4b11546289d344f","source":"amazon-inspector","versions":["1.0.3"]},{"id":"IN-MAL-2026-018421","import_time":"2026-08-19T10:44:44.733350557Z","modified_time":"2026-08-19T10:14:45Z","sha256":"d3c551a6031e48a54b550a604e2198a4491cf935407744bba8ef0c11c54086c4","source":"amazon-inspector","versions":["1.0.2"]},{"id":"IN-MAL-2026-018689","import_time":"2026-08-25T06:50:12.712027786Z","modified_time":"2026-08-25T06:44:57Z","sha256":"20ae4591662c60c5a105ccb48bf8fcf1948c36b84ffedb7e9a0be43921346a34","source":"amazon-inspector","versions":["1.0.4"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
