PyPI module 'ctx' that gets downloaded over 20,000 times a week has been compromised in a software supply chain attack with malicious versions stealing the developer's environment variables.

The threat actor even replaced the older, safe versions of 'ctx' with code that exfiltrates the developer's environment variables, to collect secrets like Amazon AWS keys and credentials.

Additionally, versions of a 'phpass' fork published to the PHP/Composer package repository Packagist had been altered to steal secrets in a similar fashion.
