My standard practice is to use command line unzip to list the contents of zipfiles (unzip -l), even those from a so-called trusted source, before extracting them. I like to know what I'm putting onto a system.

Also on Unix and their clones such as Linux you can do 'file' on it - it will tell you what type of file it is;
