Hello Guys

My parents have a bit of a dilemma, yesterday my parents neighbour approached them, and complaining that my young sister had added his address and hacked him. He was not very happy as she is only 12!

The problem that I have is how could she hack him as she is only 12, and I know for a fact she has limited knowledge of computers and hacking! She not one of them script kiddies, unless she has a friend who may be one?

Also if she didnít hacking him, how does he have her name in his contact list and how does she have his name in hers! Now the only thing that I can think of is that he has a friend or has somehow came across knowledge which has enabled him to add her address without prior approval! It would be easy for him to find her details online as she has a nick name which she uses as MSN Account!

I would basically like to how this is possible and is this due to vulnerabilities within MSN Messenger itself!

If you need technical details I believe she is running Windows XP Home with SP2 unsure about updates, her MSN version must be 7.5 I believe?

Has any one heard or came across this kind of problem before, as I would like to clear my sister's name, and then contact the authorities as I believe this guy is some sort of nutter or pervert!

I would appreciate any input in this matter, as I want it cleared up for my parentís sake and my sisterís Ė As she is reasonably mature for her age and wouldnít do this kind of thing! I am not sure what kind of trace I can do or forensics I can perform on her machine, as I am no security expert I am currently pursuing different avenues to fine a result!

Many Thanks in Advance!
