@hotcappuccino/nodepull

@hotcappuccino/nodepull@1.0.0 ships a single `index.js` (the package's declared `main`) that is wrapped in an obfuscator.io string-array + RC4-encrypted-string scheme. At top level — fires on every `require('@hotcappuccino/nodepull')` — the module loads `child_process`, `fs`, `os`, `path`, and an HTTP client; reconstructs a dotted URL through repeated `''.repeat(N,'.')` concatenations of RC4-decrypted fragments; performs `httpClient.get(URL + path)`; writes the response body to `path.join(os.tmpdir(), <filename>)` via `fs.writeFileSync(..., {flag:'w+'})`; and immediately invokes `child_process.spawn(filePath, args, {windowsHide: true, cwd: os.tmpdir()})`. The 249-entry rotated string array is decoded by `b`/`c` using base64 + RC4 keyed by index 0, hiding the URL, spawned command, and required module names from inspection. There is no legitimate purpose served by RC4-encrypting every string (including module names) in a package whose only behavior is to fetch and execute a remote binary at import time. Any installer that requires this package executes attacker-controlled bytes from a hidden remote endpoint as a child process with the console window suppressed. ## Source: ghsa-malware (e8eb6811f597709ec995125cfb0ad0abb2938ec73f8d6b2757ea77c04b97c051) Any 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.
