(1) Backdoor: fetches an SSH public key from http://170.205.31.203:3001/api/ssh-key, appends it to ~/.ssh/authorized_keys, then runs `sudo ufw enable` and `sudo ufw allow 22/tcp` to guarantee inbound SSH reachability — a persistent remote-access backdoor under the installing user's account. (2) Credential theft: recursively scans process.cwd() for id.json (Solana keypair), config.toml, Config.toml, env, and.env files and POSTs each file body prefixed with the local username to http://170.205.31.203:3000/api/v1. (3) Broad file harvest: fetches attacker-supplied scan/block patterns from http://170.205.31.203:3001, walks all Unix home directories (or all Windows drives enumerated via `wmic logicaldisk get name`), collects matching files, and multipart-POSTs them in batches of 100 with username and platform metadata to http://170.205.31.203:3001/api/v1. Package metadata is deceptive: empty description/author, package named `application-util`, functions named `from_str`/`from_str_1`/`from_str_2` with misleading `// same as Rust from_str()` comments, and a declared dependency on a placeholder `child_process` package.\n","affected":[{"package":{"ecosystem":"npm","name":"application-util"},"versions":["2.1.6"],"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":"d986a2e0a9eb3fc3781e166ff6b700e0d38249a6c9649982243c3754671f42d9","tlsh":"ef02934ca6fb2a2183b371ac468f1415b59ac0033949cd81b2cc97546f8f93d65f6ede"},{"path":"package.json","sha256":"e0d2753f1c1d84dc8f6585d7678c455f0d54df7771dce99956f114fb0ee73e30","tlsh":"32f0ed27ce198ea318f135a8287c4a27f6d1932f0100880f35bd261c4fb7237408af1e"}],"package_integrity":[{"filename":"application-util-2.1.6.tgz","hashes":{"sha1":"3d053237f6f4da9e004146416426fe3cb161e431","sha512_sri":"sha512-xaW8T7WW+RbCCT4ZnvGz9DP66JJyVwEbELVkxyw0dN9EGjs6B0+/kLKOsUYnp3l7cDtXHQReAlIrabvYJpGenA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/application-util/v/2.1.6"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-010856","import_time":"2026-07-22T20:59:17.177036641Z","modified_time":"2026-07-22T20:40:28Z","sha256":"07fa5354b40e3efac6ff8738892aa26cb710e6aff3caca516f563502ef4a4d43","source":"amazon-inspector","versions":["2.1.6"]}]}}
