Detection details
[email protected] published to pypi, flagged by codelake scanners on 2026-08-20 09:41 UTC.
Detector rules that fired on this package:
- Source decodes a payload (base64/hex/zlib) and exec/eval's it in the same file — dropper pattern
behavior.pystatic.decode-and-exec - Source calls exec()/eval() — dynamic code execution
behavior.pystatic.exec-eval - File has high Shannon entropy — likely obfuscated / packed / encrypted payload
behavior.pystatic.high-entropy - Source contains a long base64 string literal — possible embedded payload
behavior.pystatic.long-base64 - setup.py overrides an install/build command via cmdclass — runs custom code at install time
behavior.pystatic.setup-cmdclass-override - Package name 'fastapii' is one edit from popular package 'fastapi' — possible typosquat
behavior.typosquat.near-popular-name - Assembled Python string (decode, 1 fragments) reconstructs to "import os, platform, subprocess, tempfile, urllib.request\n)f platform.system() == \"Linux\":\n t = os.path.join(tempfile…" — deobfuscated-code; fed to a dynamic-execution sink
mosaic.assembled-deobfuscated-code
OSV reference: MAL-2026-13486
