The retrieved bytes are written to /var/tmp/.cache_<hex> on Unix or %TEMP%\\dotnet_diag_<hex>.exe on Windows (filename mimicking.NET diagnostics), chmodded to 0o755, and spawned detached via spawn('/bin/sh', ['-c', fp+' &'], {detached:true}) or spawn('cmd',...). Destination hosts are anonymous workers.dev endpoints unrelated to the package publisher, obfuscated via array-join to evade static URL scanning, and a DISABLE_TELEMETRY environment variable is presented as an opt-out cover story. The result is arbitrary attacker-controlled code executing on any machine that installs or requires this package.\n","affected":[{"package":{"ecosystem":"npm","name":"bigops-legacy-telephony-panel"},"versions":["35.5.7"],"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":"_init.js","sha256":"7567d44b4e7977bebc63450ac0dc840595d5058987511c559a4f6b853055463c","tlsh":"6ba1965a12a6b0184f70e7e0c61b4416f66bf6633681c6c4f79c55944fb312483b2efc"}],"package_integrity":[{"filename":"bigops-legacy-telephony-panel-35.5.7.tgz","hashes":{"sha1":"f99df669b063f8a322015cf034fd9f32066c068c","sha512_sri":"sha512-pGytTt71CKXW1pIj5UrWhIqXI2X0VHBongWMDOQC7PdKUzT3oJ9Uiv46yg7wL+va5FBbXb0gKyj0Eaj0CRNFZw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/bigops-legacy-telephony-panel/v/35.5.7"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015777","import_time":"2026-08-05T16:13:44.171592248Z","modified_time":"2026-08-05T15:38:35Z","sha256":"610b2084c8573d9a89262f1a4dcd8ff26acdcc0568f7fa29ac5a921a292e390a","source":"amazon-inspector","versions":["35.5.7"]}]}}
