I had exactly the same security concern. It seems it would be quite easy to slip in an attack via brew. I had an experience years ago where I discovered the lack of quality control: a typo (presumably) caused a package to regress back a couple of years. My issue used wording like "Are you serious?" which was taken as offensive and I was banned, unable to even apologize or defend myself from resulting attacks. brew is convenient and I still use it, but I have a much higher degree of trust in packages shipping with OS distributions.
