Description
The PyPI package 'anthropy' is a malicious typosquat of the legitimate 'anthropic' SDK. It contains code that opens a reverse shell to a remote attacker upon import or when its CLI is invoked. This allows an attacker to execute arbitrary commands on the victim's machine. The package provides no legitimate functionality and is purely designed for unauthorized remote access.
