The decoded loader only goes on if it looks like a physical Android device running Termux (it turns away x86, emulators and VMs), installs requests and cryptography if they are missing, downloads encrypted code from https://goxtools.shop/api/admin/storage.php, decrypts it with AES-256-CBC and runs it in memory. The README only calls it a runtime engine for Termux. I decoded the loader statically and did not see what the downloaded code does. I read 1.0.0 and did not run it.\n\n---\n_-= Per source details.

The visible wrapper has no other functionality; all actual behavior of the package is contained in that concealed blob. Before decoding, the module performs anti-analysis checks: it calls sys.exit(0) if sys.gettrace() returns a tracer, if the process environment/cwd/argv contain substrings such as 'uncompyle', 'pycdc', 'decompyle', 'deobfuscate', 'hook', or 'frida', and it tampers with references to builtins.exec/eval/compile. The combination of a hidden exec-of-decoded-payload reached automatically on import and explicit evasions against debuggers and decompilers is deliberate concealment of code execution from the installer and from reviewers.\n\n## Source: kam193 (780638a0747103eb44a85312a2cfb552981e498655f638c5baf86eb4a5f74042)\nPackage hides obfuscated code aimed to avoid analysis and downloading the remote stage.
