Because preinstall fires automatically on `npm install`, any machine that installs this package attempts to grant a remote party interactive command execution on the installer's host and unconditionally beacons install-time output over plain HTTP to a third-party tracking endpoint. The nip.io wrapper resolves the bare IP 147.93.157.202 without DNS registration, and the destination and token are hardcoded in the manifest with no caller configuration path.\n","modified":"2026-09-21T03:30:16.618339369Z","published":"2026-09-21T02:59:02Z","database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","versions":["1.1.0"],"id":"IN-MAL-2026-020196","import_time":"2026-09-21T03:24:20.4072804Z","modified_time":"2026-09-21T02:59:02Z","sha256":"537505221bc3cd73b0d5a60062d6ad127211b2d1be1f1cdfdac13053e2224a11"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@nimbusedge2/xa/v/1.1.0"}],"affected":[{"package":{"name":"@nimbusedge2/xa","ecosystem":"npm","purl":"pkg:npm/%40nimbusedge2/xa"},"versions":["1.1.0"],"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":[{"sha256":"16ed5daa76824511c01c620180afba0600b7f9380d8bc52a2f71a570341c11df","tlsh":"b9e0c0301510683b38c94bd5752243a93a74771f4ce05c1894d302492b1d9d93917e48","path":"package.json"}],"package_integrity":[{"filename":"xa-1.1.0.tgz","hashes":{"sha1":"7952554397c2191667df3f340336719beccbe7d4","sha512_sri":"sha512-KSxFPNnZFLp+/aYsjdqU6u3biGmjsnVFRIdjVVwcTQ2xQg2efixrTg7H4XNmtvh433HA60YB61hJlTlulHMXtA=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@nimbusedge2/xa/MAL-2026-16306.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
