Bluesnarfing: A first person's perspective...

I've heard a lot of bluejacking, bluesnarfing and bluebugging. Bluejacking is pretty harmless, because it consists of sending messages via bluetooth. But bluesnarfing (discreetly copying data from a mobile phone trhough bluetooth) and bluebugging (initiating phone calls from another bt-enabled phone, again discreetly) is really sisnister. There are a lot of papers available that discuss these attacks, but until now all I had was an audience's perspective. I had never seen what it really looks like. Until now.
I have a Nokia 6600 smartphone, and I'm used to downloading odd apps and trying them out. I saw an app called Blooover, and thought it's pretty interesting so I loaded it up. The home page says:
"Blooover is a proof-of-concept tool that is intended to run on J2ME-enabled cell phones that appear to be comparably seamless. Blooover is a tool that is intended to serve as an audit tool that people can use to check whether their phones and phones of friends and employees are vulnerable."

Pretty interesting stuff! I tried it on my sister's Nokia 3660, and friend's 3650's and 6600's, but it didn't work. Kept saying that the phones are not vulnerable to this attack. I promptly forgot all about the app. Yesterday, I was at a canference at a local 5-star hotel, and just happened to do a bluetooth scan to find out what phones in my vicinity have bluetooth enabled. I saw a few T610's, T630's and K700i's, alongwith a few 6600's, a 3650, and 2 6310i's. The 6310's are really old bluetooth-enabled mobiles from Nokia, and I happened to remember reading that they were vulnerable to bluesnarfing. So I decided to fire up Blooover and give it a whirl. Imagine my surprise when Blooover started giving me visual cues that the bluesnarf was proceeding successfully! It managed to get all the contacts in phone memory, all the contacts in the SIM card, all call logs (missed, dialled and received calls), all SMS (some were garbled with weird characters, but some of them even had his bank name, branch, account number and balance!). Blooover also managed to add a phone-entry of my own choosing, set the call forward to a default number, and initiated a call to another default number. Now that was amazing! I have all the logs with me. Blooover doesn't provide a way to save the log, but I turned on the screenshot feature of FExplorer, and took screenshots to save the whole data. I'm not willing to reveal it, as it contains personal information, but I felt scared and elated at the same time. I tried it on another Nokia 6310i, with the same results!
As I said in my last post about Google's revealing webcam searches, everything is inherently insecure. Any person with enough knowledge (or as in my case, little knowledge, but the right tools) can get in. Data that you think is safe and secret may not be so.


  • Can you please tell s how you install Bloover, I cant get it to work on my 7610, where do I stick the files and folders.

  • I simply downloaded the Blooover java archive from this address:
    Sent it to my phone, and opened the received message. This prompted me to install the program and I did. That's all there is to it. If you're still having problems, please do let me know.

  • Hey...i cant get blooover 2 work on my nokia 6230.. it says file of an unsupported type...please help!

    By Anonymous J, at 1:46 PM  

  • I downloaded it a while back with no problems.. I got the exact same result you got when it was activated. Complete phone book, calendar, note book, sms's the lot. It's kind of freeky what u can get and makes u think how safe u really are. Most of the information i got was useless to me but imagine getting this kind of stuff from someone important. hmmm worked a treat for me. I sit in heavy traffic and scan for bluetooth all the time just to see who's dumb enough to leave it on. I advise that if your not using your bluetooth, TURN IT OFF.
