## Overview


---
_-= Per source details. Do not edit below this line.=-_

## Source: kam193 (79cc4c6495567fe7659e9e4bb5964727bf95cfc9f78d32209937d73457bd476b)
Packages contain hidden code that is effectively run during importing or using the library, and downloads second stage code. Then, a process running in background periodically connects to a remote host and waits for the next code to execute.

The malicious code was in version 1.3.0, but the package itself was clearly uploaded with malclious intentions.
