The script shells out via child_process.exec to collect host reconnaissance — hostname, whoami, id, uname, pwd, /etc/os-release, HOME, SHELL, container indicators, /proc/1/cgroup, network interfaces, and running process list — base64-encodes the data, and sends it via HTTP GET to a hardcoded Burp Collaborator subdomain at pwpzhsrbtvmfqrqr7onqcwnrcii960up.oastify.com/ing?d=<base64>. The stated purpose of the package does not require any shell execution or network activity; the install-time reconnaissance beacon is unrelated to the advertised functionality.\n","affected":[{"package":{"ecosystem":"npm","name":"date-utils-light"},"versions":["1.0.1"],"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":"postinstall.js","sha256":"7b4573190bb073f2fe5e455e012fa2ee4a6547d0641ca49d30e38485e1bc6348","tlsh":"320189f8b978d970324ad0f6b95d191738835a9f21b4ffb808478cb5819d5c410be572"},{"path":"package.json","sha256":"f8da84b39ece6ab2b13c469c348898418c13c20b56483deab8a954d94127e22b","tlsh":"e6e0263888019d232ac00aa6496a8906ae509e074114781933a7201c879f67f84ff35d"}],"package_integrity":[{"filename":"date-utils-light-1.0.1.tgz","hashes":{"sha1":"173b407b350c463ecf40f4a8029879fc94b868e2","sha512_sri":"sha512-sHUlc2YQpugflgUhgrw9LZUoT5igdbmbLTRLRXfXiDMEA5m7Yb2QU6pXkJMd9/ms9w4/WqkEUrWbld383FcgFg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/date-utils-light/v/1.0.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-010721","import_time":"2026-07-16T18:54:01.154484939Z","modified_time":"2026-07-16T18:37:41Z","sha256":"99bd644fd9a59518d6f77e8d76c077ffef8a2afdc7ae2b00a6ca87299879a671","source":"amazon-inspector","versions":["1.0.1"]}]}}
