Description
The spellcheckpy package versions 1.1.0 and 1.2.0 on PyPI contain hidden malicious code that executes upon import or use. This code downloads and runs a second-stage payload, which then runs a background process that periodically connects to a remote host to receive further commands. The package is designed to execute remote commands on the victim's machine, indicating clear malicious intent.
