## Source: amazon-inspector (6d316a35a6fe335032b2c59e47627c0af28bec9688cba40585f1365cab4f4452)
getpubip/__init__.py runs exec() on an approximately 2KB opaque payload produced by reversing a string literal, base64-decoding it, and zlib-decompressing it (lambda __: __import__('zlib').decompress(__import__('base64').b64decode(__[::-1])); exec(_(b'...'))). The package advertises itself as a three-line helper that returns the host's public IP by calling ipify, and a clean implementation of that functionality exists in core.py; __init__.py does not re-export get_ip and its only effect on import is to execute the hidden blob. The payload is reached whenever a consumer runs `import getpubip` or `python -m getpubip`, so any installer that uses the package executes the concealed code with no further user action. The triple-layered obfuscation (string reverse, base64, zlib) and single-character identifiers are deliberately chosen to hide the executed code from reviewers; whatever the decoded bytes do runs in the installer's process on first import.

During import, obfuscated code downloads and executes an infostealer. Campaign shares some similarities with the campaign 2026-10-fontcase.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.


Campaign: 2026-10-getpubip


Reasons (based on the campaign):


 - Downloads and executes a remote executable.


 - infostealer


 - exfiltration-browser-data


 - obfuscation
