Its postinstall.js runs on npm install and collects host identity (os.hostname, os.userInfo, process.cwd), reads /etc/hostname, /etc/hosts, /etc/resolv.conf, and /proc/version, filters process.env for credential-shaped keys matching a broad regex (token/secret/key/pass/aws/db/jwt/auth/etc.), and walks parent directories to read.env and config.* files. Each payload is base64-encoded and transmitted via three HTTPS GET beacons to akko.requestcatcher.com, with an additional hex-encoded DNS beacon of hostname+user to the same domain. A README/comment self-labeling the code as a 'HARMLESS PoC' does not change the observed behavior: credential-shaped environment variables, dotenv files, and internal network configuration leave the installer's build host to a third-party request-catcher.\n","affected":[{"package":{"name":"@umschool/analytics","ecosystem":"npm"},"versions":["999.0.1","999.0.0","999.0.2","999.0.4","999.0.3"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"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":"9fa1a2280370830680e73bb23c8185c40e442d46a60bbd845a2f98e48f590edb","tlsh":"0b21e5b524b4f37c18b20ac194a6985b6163e3013102f8c0b86d136d5bddee528a74fe"},{"path":"package.json","sha256":"e9214653648775a79e85ef9c5afc609da0b57468667660e343084da49951135e","tlsh":"64e02659242412332cd282a6083260096524ce064145b91c17d72284828eb6345fa39d"}],"package_integrity":[{"filename":"analytics-999.0.1.tgz","hashes":{"sha1":"63a69e7156d323b4bc8cc3b7f0629e0b9d304744","sha512_sri":"sha512-fztSb711q5a4YnMdbkProlUm88aO/URGtUzg+nhf3iiTfpOg5rCAgsmAqe0t7UC2uOjNwb6CLbngKJ+sO71dBg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@umschool/analytics/v/999.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@umschool/analytics/v/999.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@umschool/analytics/v/999.0.2"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@umschool/analytics/v/999.0.4"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@umschool/analytics/v/999.0.3"}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-019715","import_time":"2026-09-08T21:14:30.933342582Z","modified_time":"2026-09-08T21:04:35Z","sha256":"730be45f4ca0d1b8df021cbd506e8ee293c8e9bc4a8ad3854b42408bd80e3162","source":"amazon-inspector","versions":["999.0.1"]},{"id":"IN-MAL-2026-019716","import_time":"2026-09-08T21:14:30.998808771Z","modified_time":"2026-09-08T21:04:44Z","sha256":"7ce44bf9d1ffcc0a63fbc4e955c97cbd45f928e90ba052c49d4cce211b7fed96","source":"amazon-inspector","versions":["999.0.0"]},{"id":"IN-MAL-2026-019737","import_time":"2026-09-09T01:51:47.650395877Z","modified_time":"2026-09-09T01:32:34Z","sha256":"b97a13f964bb64cd1a38a1e31b247917d6cea8f7aeae7bba3a6b7e6aa1feb4ef","source":"amazon-inspector","versions":["999.0.2"]},{"id":"IN-MAL-2026-019736","import_time":"2026-09-09T01:51:47.500023483Z","modified_time":"2026-09-09T01:32:23Z","sha256":"da14c2843514d3c9103335648bc81a8bce18fc173b27c2ab39ebe2c6c0abe028","source":"amazon-inspector","versions":["999.0.4"]},{"id":"IN-MAL-2026-019738","import_time":"2026-09-09T01:51:47.823483096Z","modified_time":"2026-09-09T01:32:41Z","sha256":"979621128350544996205e9516804472bf66eec1ff9f22a57111756158e9af8b","source":"amazon-inspector","versions":["999.0.3"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
