Is it likely that the deletion of libcrypto was the result of a successful intrusion attempt? I assume this is why you say not to "trust the box".Don't know. It's like when your Mom used to say, "Who took this" and no one answered. I'll assume that someone had access to your box on March 11 such as a contractor or how else did openssl even end up in that directory in the first place?
The file /export/home/admin openssl-18.104.22.168d was created Mar '11 so I'm guessing that wasn't via an attacker.
So my options are gmake install openssl again? or not use the box?I'm assuming that it was compiled and just left in that directory. If it was then gmake install would do it. If not then you're going to need to download if from somewhere and then move it onto the box, compile it, and then install it.
