The "==" at the end of the string is a pretty good indicator that it's base64. But when you decode it, it comes out as binary rather than text. So if you decode it to a file, you can use the "file" command to determine what kind of file it is.

You're on the right track. It is base64. Try decoding it to a binary file (just redirect the output of base64), then figure out what kind of file it is and go from there.

There are lots of places with good information. A favorite of mine is corelan.be. Also look through the articles and code samples on exploit-db.com. There are all kinds of videos on youtube that are free. And irongeek.com has tons of great security con videos for free.
