The script collects host reconnaissance (os.hostname(), os.userInfo().username, home directory, DNS servers, __dirname) and reads the contents of /etc/passwd and /etc/hosts from the installer's machine, then HTTPS-POSTs a JSON payload to the hardcoded Burp Collaborator subdomain 5tzh3l2e1cetr1chf6osh4tg57b0zqnf.oastify.com. The behavior is unrelated to the package's advertised purpose as a React app template and is characteristic of a dependency-confusion exfiltration payload.\n\n## Source: ghsa-malware (5730446a57eddb68dce69772a61c937fdf59edbe7da88fdc2def5383aea446cf)\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.\n","aliases":["GHSA-wvfj-f49f-7vqw"],"modified":"2026-09-09T03:30:11.048001052Z","published":"2026-07-28T13:32:08Z","database_specific":{"malicious-packages-origins":[{"sha256":"844a2ac73b588b6c0c7c370dd647685768992ff3e6b5ef492e6fc6dc6be240ce","source":"amazon-inspector","versions":["1.0.1"],"id":"IN-MAL-2026-010888","import_time":"2026-07-28T14:19:57.593525625Z","modified_time":"2026-07-28T13:32:08Z"},{"modified_time":"2026-09-07T16:17:42Z","ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"sha256":"5730446a57eddb68dce69772a61c937fdf59edbe7da88fdc2def5383aea446cf","source":"ghsa-malware","id":"GHSA-wvfj-f49f-7vqw","import_time":"2026-09-08T00:15:11.432899618Z"},{"sha256":"168645cb7d79fb14fc92cbfa3644498542e9231231f0d468036c86430795c343","source":"amazon-inspector","versions":["1.1.1"],"id":"IN-MAL-2026-019820","import_time":"2026-09-09T03:21:57.153359432Z","modified_time":"2026-09-09T02:50:40Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/jobber-app-template-react/v/1.0.1"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-wvfj-f49f-7vqw"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/jobber-app-template-react/v/1.1.1"}],"affected":[{"package":{"name":"jobber-app-template-react","ecosystem":"npm","purl":"pkg:npm/jobber-app-template-react"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["1.0.1","1.1.1"],"database_specific":{"indicators":{"evidence_files":[{"path":"index.js","sha256":"2afb1d416ef5f5bc9005a931402bc4f998499fdb1f71b8193ecc71d170a1fd5f","tlsh":"d041259562d917330de110c06a0c70812359fa777159a99077cf42d69f869f8b7316f3"}],"package_integrity":[{"filename":"jobber-app-template-react-1.0.1.tgz","hashes":{"sha512_sri":"sha512-SnbjtkTkFtq8grR44J7L2PKebeo7BWWEci8D46Qk+l8iZMrkO/Gj+QIUHZlQn5JmwhE4Y7WDAQc8owqZEu0wXA==","sha1":"9d68aa385477667bc205333cf7f26c183d6c2194"}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/jobber-app-template-react/MAL-2026-11137.json","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"},{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}]}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
