Malicious code in uitil (PyPI)
Details
--- _-= Per source details. Do not edit below this line.=-_ ## Source: kam193 (ff0b75197d8e7cd361d61461260811fba8920c54b8538cb5f21ec2fc1c885ec3) The package implements an undocumented way to execute code hidden in image files, and a function that searches for images in the current directory and attempts to execute the code. It's used in the GitHub repository https://github.com/OR-6/PassCheck/blob/main/main.py#L190 to silently execute the command hidden in the image https://github.com/OR-6/PassCheck/blob/b09b3f1ec5d7345c614b1d956840ee2774f7131b/demo.png when the user interacts with the repository code. The decrypted command attempted to download and execute code from hxxps://or-6.github[.]io, which at the time of analysis didn't host any code. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-01-uitil Reasons (based on the campaign): - typosquatting - steganography - The malicious code is intentionally included in a dependency of the package - action-hidden-in-lib-usage - The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.
