Facebook IP Hack - Amazing

[HarryTiger]

Want to know the IP address of fellow Facebook users? Yep THEIR IP, not the FB server. It's too easy.

The thing that allows you to get it is the notification FB can send to your email in response to something as mundane as a reply on a thread you have replied to. In fact I'm not sure if other notifications allow this but the thread reply one certainly does.

You need to view full email header in the notification email. Yahoo mail can do this. I found it easier in Classic mode where the icon is down the bottom right. I read Hotmail can do this too but Gmail cannot.

With full header in view look for tag

X-Facebook: from zuckmail ([NjIuNDQuMTM0LjMz]) by www.facebook.com with HTTP (ZuckMail);

Now that nonsense string in the brackets is actually a Base64 encoding of the initiator's IP address. In between the square brackets is the part we decode.

So over to a site like this (check decode)

http://www.motobit.com/util/base64-decoder-encoder.asp

And

NjIuNDQuMTM0LjMz

decodes to

62.44.134.33

That's their IP.

To make more sense of it do a trace.

http://www.ip-adress.com/ip_tracer/62.44.134.33
http://network-tools.com/default.asp?prog=express&host=62.44.134.33

That FB user is in Denmark. Usually you can tell the ISP as well though that doesn't do it (no reverse look up?)

Where this really becomes powerful is when people are trolling with fake profiles and you suspect they might be some other real profile. If two users have the same IP then you know they are logging in from the same PC. Or could be non-static but still same location and ISP across different sessions. Use your common sense.

Go on Osama Bin Laden's facebook and use this hack to find where the bugger is hiding!

So why should the average Internet user who's not into hacking care what someone else's IP address is?

I never postulated that they should be. Perhaps you have the answer?

Well wouldn't creating a thread instructing people how to discover someone's IP address via Facebook/email imply that this is something they should know/care about?

 

[HarryTiger]

No, it doesn't imply EVERYONE should care about it.

Instructions on how to determine another user's IP address would be useful to people who want to know other users IP addresses. If that isn't you then feel free to bypass the thread.

And I did actually give you an example where it can be useful, and if you need a few more type "facebook defamation" into google.

I was just having a friendly dig mate I'm obviously among those for whom this information isn't useful. Carry on

Very useful to me, cheers. Some clown has made a facebook and jokingly insulted at least 10 people with personal insults that only a select few should know.

I'm not too sure if I can weed him/her out and expose him/her but it's a step in the right direction.

This tool may help if you get the IP addresses.

This might come useful for those stalkers.
