Javascript compiled or not? Check inside

Question

Note that I am not experienced with Javascript. If a javascript code starts like this:

javascript:var _0x89f8=[\"\\x69\\x6E\\x6E\\x65\\x72\\x48\\x54\\x4D\\x4         


        

Answer 1

Well, I have to admit, I was curious enough that I opened a new facebook profile to find out what this thing does...

after reading the un-obfuscated code you can determine that this script will automatically open your Friend's list, and suggest just this Facebook page to all your friends (the amount allowed, of course). Therefor sending out invitations (unknowingly) to all of your friends, which some will undoubtedly continue...

Simply put, don't copy any JavaScript lines without knowing who posted them in the first place. :)
