While I use Homebrew on my Mac — it is a major risk. I am afraid that the project is not following strict security policies and will be compromised at some point. Evil package or evil version of brew can steal or modify my data. I think this will also hurt the Mac platform. I wish Apple would invest some effort into building an App Store for cli programs. While it may be complicated for the community(require signing,…
This is a genuine question: what is your threat model, and what security policies would you like to see? It's hard to imagine a threat model that assumes an "evil version of brew" that doesn't also prevent you from installing any third-party software on your machine. Malicious packages are always possible, but Homebrew's integrity checks do an adequate (but improvable!) job of making such attacks auditable; I'm not aware of any successful supply-chain attacks mounted against Homebrew users.
I have a lot of experience with various package managers, and Homebrew is not particularly out of band with its peers (which should be read, partially, as a general indictment of packaging practices).
