The loader queries Ethereum RPC/blockscout endpoints for transactions from the hardcoded address 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, extracts an IPv4 address from the transaction's `to` field, fetches an XOR-encoded payload from http://<resolved-ip>:443/0x/cls and /0x/ls (XOR key delivered via the x-payload-b64 response header), eval()s the decrypted payload, and spawns a detached `node -e <payload>` child process with stdio:'ignore' and windowsHide:true. Sensitive strings (`http`, `https`, `child_process`, `spawn`, endpoint paths) are hidden behind \\u unicode escapes. The malicious code executes automatically at require/import time on any consumer of the package.\n","affected":[{"package":{"ecosystem":"npm","name":"devpack-conf"},"versions":["5.0.0"],"database_specific":{"cwes":[{"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":"ac54ffef7ef6d8f59e47a0983c974f35e64f7550e14e1a91d0f1a06610f1252a","tlsh":"37522eaa4692bb9bcb1b2673fc87570d237840b67a9c2b45310fd874b389c55748e60f"}],"package_integrity":[{"filename":"devpack-conf-5.0.0.tgz","hashes":{"sha1":"2f3d7eccc5f76ce2479eeed9c446aef3fc6e0ea0","sha512_sri":"sha512-G4bcVVD0T3ZxhG4fH1O+Yh1QsHJhsaEzbk4iusUENg1YmWiDgBzeHGqVg6CBthMHLdWycIuUEc34Pv3hOI3ZBA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/devpack-conf/v/5.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-014434","import_time":"2026-08-05T09:28:10.642709711Z","modified_time":"2026-08-05T08:49:50Z","sha256":"fabc4baeb912d72d08ef42d8b6b5e147b1f7dc18fc01e796bc6ac17f1c7dff68","source":"amazon-inspector","versions":["5.0.0"]}]}}
