Summary: Malicious code in aitextkit-py (PyPI)

Details: Source: amazon-inspector (47e96f519e8acba48a6f7760b37a9ad70b94bfbf79fb5eac4fc682849b2837e3) The package presents itself as a small text-cleaning utility library, but both shipped implementation modules (text.py and system.py) consist of a single-line pyobfuscator.com loader of the form `_ = lambda __: __import__('zlib').decompress(__import__('base64').b64decode(__[::-1]));exec((_)(b'...'))`, which reverses, base64-decodes, zlib-decompresses, and exec()s an opaque blob at module import. __init__.py imports from.text, so `import aitextkit` runs the decoded bytes on the installer's Python interpreter. __init__.py also re-exports an undocumented `setup` symbol whose body lives inside the obfuscated blob and which is not mentioned in the README, tests, or public API documentation - a common stager entry-point shape. system.py, which backs the documented `get_os_version()` helper, uses the identical loader and its tests reference `platform`, `release`, and `arch` fields, so the decoded code at minimum performs host enumeration inside code that is not inspectable from source. The declared text-utility purpose has no legitimate need to ship its entire implementation as an exec-decoded blob; the loader shape matches that used by PyPI credential-stealer families.

The remote stages are hosted on a domain presenting a suspicious-looking corporate website. The downloaded code establishes persistence e.g. as "anymeetly-cameradriver" systemd service. The discovered artifacts suggest strongly it acts as an infostealer and RAT. Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-09-aitextkit-py Reasons (based on the campaign): - obfuscation - Downloads and executes a remote malicious script. - persistence - infostealer - exfiltration-browser-data - rat - The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.
