The 'filewisee' npm package, specifically versions 0.1.0 and 0.1.1, exports a function 'formatd' that, when called, downloads a binary from an anonymous file host (pixeldrain.com), writes it to a hidden directory (~/.drc/dr), sets executable permissions, and runs it with hidden process options. There is no integrity verification of the binary, and the host is unrelated to the package publisher. The package's API surface is designed to appear as a legitimate date-formatting utility, increasing the likelihood that users will invoke the malicious function unknowingly. This behavior effectively compromises any system running the package.

Any computer with the affected versions of 'filewisee' installed or running should be considered fully compromised. The malicious binary executed by the package may grant full control to an attacker. All secrets and keys stored on the compromised system should be rotated immediately from a separate, trusted environment. Removing the package alone does not guarantee removal of all malicious components or backdoors installed by the binary.

Immediate removal of the 'filewisee' package versions 0.1.0 and 0.1.1 is recommended. All credentials and secrets stored on the affected system should be rotated from a different, secure machine. Due to the high likelihood of full system compromise, a full system investigation and remediation is advised. No official patch or fix is available; users should avoid installing or running this package.
