python-module-installer @3.15.10

Summary

The package clones a legitimate webdavclient3 library and modifies it to be an installer utility. During installation, the package exfiltrates the current working directory to a remote WebDAV server or Telegram Bot. Additionally, the package targets cryptocurrency operations in another suspicious project, https://github.com/fewcatltd/zkSync/ The install_modules() method injects code into two files, which are characteristic for this repository, and causes exfiltrating configuration files during cryptocurrency exchange operations. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
