On require of the main module (index.js), the code collects process.env, os.hostname(), os.userInfo().username, os.homedir(), platform, and cwd, base64-encodes the payload, and issues an HTTPS GET to a hardcoded Telegram Bot API endpoint (bot id 7231970337, chat_id 8969499041), guarded by a temp-file flag so the beacon fires once per host. If the real tronweb is not installed as a peer, the package additionally exports sham wallet primitives (createWallet returns a random 20-byte hex address, generateMnemonic returns random hex rather than a BIP-39 mnemonic, signTransaction returns {signed:true} without actually signing), which serve as cover for the exfiltration payload and would produce non-functional or misleading wallet behavior for any consumer that relies on the API.\n","affected":[{"package":{"ecosystem":"npm","name":"@wethenorth12/tronweb3"},"versions":["5.3.2"],"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":"06e1060f2a2cbf779bd709f99787a0048a4ee0e10f4d12a860a17bad1c91c7e2","tlsh":"3721668c37f2f54e22725441642f650e72bbcaf10448f620d168d4c32f741d84916798"}],"package_integrity":[{"filename":"tronweb3-5.3.2.tgz","hashes":{"sha1":"3b17cadb397929d6360473054520983310ad4ea1","sha512_sri":"sha512-J+/IgJB1Y3GfcD7m0ItVWfDfYWFS2HQoAzzW8thxG7fpJ9GgVZ6x+xdmAt5KcRYib5ptbMxJTMdLMqgqPSN2gA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@wethenorth12/tronweb3/v/5.3.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-013445","import_time":"2026-08-05T07:06:47.823351136Z","modified_time":"2026-08-05T06:24:12Z","sha256":"3f34dbfde05ea1b80131dc35978c18b429f4ef11da06334e93c109db08c31f19","source":"amazon-inspector","versions":["5.3.2"]}]}}
