Interesting Hack... the posibilities in simple tools

today my friend told me about an old program i once had installed on my system. it was about windows plus. i really liked the program because it allowed a greater variety of use compared to the regular msn. he told me that with the use of the scripts he was able to get files from other computers so long as they had the msn installed. this is because scripts had already been made that were able to take images from another user online. but he edited the script so as to be able to get the file itself. the script was not limited to only that file and it allowed the user to get any file from the other user. it is a really obvious back door but not many of us ever noticed. its just another interesting thing that can be broken down into evil with a few changes in code. what do you think about this and do you feel our files online are really safe from the grasp others?
