There once was an amazing culture (and a sense of community) around the curation of tools. Just as I was browsing cybersectools, I remembered exetools(.com), which amazingly still seems to exist. There are even some aesthetic similarities to this submission, I think.

I also vaguely remember a very large registry that specialized in packers for executables, but I can't remember the name. Those were great for reducing the size of executable files, among other things. I don't think that's even a thing anymore. Still good times.
