@hotcappuccino/nodepull versions 1.0.0 and 1.0.1 ship a single obfuscated JavaScript file that, when required, decrypts and reconstructs a remote URL, downloads a binary from that URL, writes it to the system's temporary directory, and executes it as a child process with hidden console output. The obfuscation uses a large rotated string array combined with base64 and RC4 encryption to conceal URLs, commands, and module names. This behavior provides no legitimate functionality and indicates the package is a malicious backdoor that grants attacker-controlled code execution on the host system.

Any system that installs or runs this package is fully compromised, as attacker-controlled code is executed with the privileges of the running process. Secrets and keys stored on the compromised system should be considered exposed and rotated immediately. Removing the package alone may not remove all malicious artifacts or persistence mechanisms installed by the executed payload.

Remove the @hotcappuccino/nodepull package immediately from all systems. Rotate all secrets, credentials, and keys that were stored or accessible on affected systems from a secure, uncompromised environment. Conduct a thorough incident response to identify and remediate any additional malware or persistence mechanisms installed by the executed remote binary. There is no known patch or fixed version; the package itself is malicious and should not be used.
