Vulnerability from ossf_malicious_packages
-= Per source details. Do not edit below this line.=-
Source: amazon-inspector (5414e9956c915ef34d422d9eba09177fb667bba375c43e9d9b54d4f87b628712)
During pip install goodoldtoulas, setup.py invokes setup_helper() which downloads main.exe from https://cold-eu-par-1.gofile.io/download/web/deb39e07-da2d-4081-a86b-6380e555788c/main.exe (anonymous file host) into C:\MALWARE_DELETE and executes it via os.system('main.exe') (setup.py lines 6, 21, 33). The fetch is unpinned, has no hash verification, the destination is an opaque Windows binary, the host is not the publisher's domain, and the staging path name is self-incriminating. Any installer running pip install of this package on Windows fetches and executes an attacker-controlled binary at install time.
