The `addToStartup` routine then writes an HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Run entry pointing at `~/.react-pul/DOContentCacheMgr.exe`, autostarting the dropped binary on every user login. The package name and description present it as a generic React utility, unrelated to the shipped behavior.\n","modified":"2026-07-28T14:37:07.939922847Z","published":"2026-07-28T13:39:15Z","database_specific":{"malicious-packages-origins":[{"sha256":"a3ac07c0f6c79714a7b1f6bfd1272f9f7942cf0473875ca5276a1034c084f06d","source":"amazon-inspector","versions":["1.0.0"],"id":"IN-MAL-2026-010939","import_time":"2026-07-28T14:20:00.140878431Z","modified_time":"2026-07-28T13:39:15Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/react-puller/v/1.0.0"}],"affected":[{"package":{"name":"react-puller","ecosystem":"npm","purl":"pkg:npm/react-puller"},"versions":["1.0.0"],"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":[{"tlsh":"5be1a54e25f2617557a320f8971b952ab65b8803310ddc94fa5c43847f8a6aac2f2bcd","path":"index.js","sha256":"27b9d3e11df59a06fe44933601a8856dab28e18dd3ddb7a51fd28824cba0709f"}],"package_integrity":[{"filename":"react-puller-1.0.0.tgz","hashes":{"sha512_sri":"sha512-kX6oSRqJ76iBZGQQu65qTmvQmc1gvQVcGFSizj4ncXqa8v1QJndlUwQEP6nZpe/JVn0gpGGBwINs12Dgzbga9w==","sha1":"19b7fb7be2bb4e8ac586bb1f8e7f70c50be76b4c"}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/react-puller/MAL-2026-11144.json"}}],"schema_version":"1.7.5","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
