The script hex-decodes and concatenates a hardcoded destination hostname resolving to gwfqp5cm9r2jfs3d6mjpzt8y5pbkzanz.oastify.com (a Burp Collaborator subdomain), then sleeps a randomized 30-120 seconds and issues HTTP POSTs on port 80 carrying: os.hostname, platform, arch, cwd, whoami/id/uname output, the contents of package.json, the full process.env, the contents of ~/.npmrc (which normally holds npm _authToken values), `npm root -g`, local port scan results, and Windows recon (ver, tasklist, USERPROFILE). The payload exits silently when CI, GITHUB_ACTIONS, GITLAB_CI, JENKINS_HOME, npm audit/pack/publish flags, /.dockerenv, or docker/kubepods cgroups are detected, and exports a benign-looking function as a facade. The exfiltrated ~/.npmrc auth tokens and environment variables give the operator credentials to publish malicious versions of the installer's other packages and to access CI cloud secrets.\n","affected":[{"package":{"ecosystem":"npm","name":"coin-fees"},"versions":["20.1.1"],"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":"index.js","sha256":"723a872c1dbe3eec92d37841ce093baa8f9c946e04c2621b5b37efed162ba8ef","tlsh":"85b1949272fb9e70362261e583a3d0277726f0073508eac0ba4c9b46df9f60595d28f9"}],"package_integrity":[{"filename":"coin-fees-20.1.1.tgz","hashes":{"sha1":"1d7c6c8d9e94e12fd59a4c7010ce6c793e51541a","sha512_sri":"sha512-Mi60G1hgndIMcIcClVAu72KQrA/7mVuPPiLgA7kje+FGsrI7k0Gj/zTPL87wvVd+zYX8Myr63aQwKx8eud++Xw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/coin-fees/v/20.1.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-018490","import_time":"2026-08-21T03:26:10.350501272Z","modified_time":"2026-08-21T03:07:50Z","sha256":"f47c61fd59fb65dc8c8932e3e913dd83f18fc8af1d5f06b03cae327228821703","source":"amazon-inspector","versions":["20.1.1"]}]}}
