I was recently browsing my Fedora's /bin
folder and noticed a binary named [
.
I did try to search the internet for more information on that, but I couldn't find anything useful. Running it through strace

What is that? Should I be alarmed? Could it be the result of a system compromise? Should I run it? Does it belong to any package?
