A TTL marker suppresses re-execution. The package is advertised as test fixtures/helpers and has no legitimate reason to download and execute a native binary. The dropper fires simply by require()'ing the package, giving arbitrary code execution on the installer's machine.\n","affected":[{"package":{"ecosystem":"npm","name":"devplatform-test-pvm-is-even"},"versions":["35.9.5"],"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":"_runtime.js","sha256":"dfd05aa72cb2c674f0b921cd3d63f170148741a1a3e1db17ea9c9c2df71f89d9","tlsh":"40a1975a05aa70198bb0d7e487174816f65bf6633381c298fb6c55981f7712883b2efc"}],"package_integrity":[{"filename":"devplatform-test-pvm-is-even-35.9.5.tgz","hashes":{"sha1":"1214d92ef371695b2e04819c2d61062a1802df7e","sha512_sri":"sha512-DuF4ojiKD7+zAc8oHmX2xzjBP35zPCBmoMJeGWb5upMiizYZjcAnhw5IUkB4IQl2FTyIoU5XfLFlA+avj4V7YQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/devplatform-test-pvm-is-even/v/35.9.5"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015734","import_time":"2026-08-05T16:13:37.848160346Z","modified_time":"2026-08-05T15:31:51Z","sha256":"4ab114c230ec1d462306a74f0eaaddf32474b1fae0087e1038ab2e280637d558","source":"amazon-inspector","versions":["35.9.5"]}]}}
