GCVE-110-OSM-2026-12871

py-0requests is a homoglyph typosquat of the PyPI package `requests` (letter `o` replaced with digit `0`). On `import py_0requests`, top-level code in the package's `__init__.py` scrapes `os.environ` for keys prefixed with SECRET, API, TOKEN, or KEY and sends the collected dictionary over a TCP socket to a host/port read from `TS_HOST`/`TS_PORT` (defaulting to 127.0.0.1:9999). The same import path spawns a Python subprocess that opens a TCP connection to the same destination, sends a `SHELL` marker, and holds the socket open, providing a reverse-shell handshake to whichever operator controls the destination. The package's CLI banner self-identifies as `targeting requests` and ships no HTTP-client API. During import, the code exfiltrates potentially sensitive env variables. In all analyzed versions the exfiltration target was a localhost, suggesting it was just a test.
