Finding the name behind the gmail address

Ever wondered what name is behind some obscure gmail address? Maybe your preferred gmail address was taken and you’re wondering who took it?
Here’s a cute vulnerability in the gmail system that comes from the strong tie-ins between gmail, the google calendar and all the other services.

How to do it:

- Go to the ‘share this calendar’ tab

- Enter the email address in the ‘person’ box

- Click ‘add person’ and ‘save’

- When you return to this screen you will see the first and last name along with the gmail address

Screenshots:

I always wondered who was behind admin@gmail.com

Tell google you want to share your calendar and put their gmail email address

Oh, I guess they figured people like me would be interested…

admin@gmail.com is a smart ass

If you are getting personalized emails from spammers to your gmail account, here’s an idea on how they got your name.

    that’s only good if they used their real name. some people use fake names or just repeat the the email address itself as the real name. Still it is interesting that you can easily get this information like that…

  • Wonder

    I wonder who is behind security@gmail.com, root@gmail.com, and of course billgates@gmail.com :)

  • Maruti Borker

    Doesnt work anymore :)

  • Eric TF Bat

    It still works (or at least it did half an hour ago) but the person you select gets sent an email to tell them you’ve shared your calendar with them, so I think as a sneaky method to find someone’s name it has a few flaws…

    Eric – you’re right, of course, unless they don’t have a gmail calendar account (only a gmail account) in which case you’ll be prompted to invite them to google calendar. I believe that if you click ‘don’t invite’ they don’t get anything.

    Also, if you really want to cover your tracks, open a fake gmail account under a fake name. They will know ‘someone’ shared their calendar with them, but they won’t know it was you (and I’m betting that if you use a gmail username like ‘v1agra4cheap’ they won’t give it much thought).

    I’ve got to admit, though, that my experience as a stalker is very limited :-)

  • Fliffy

    What if they use their real name as e-mail address? Does the internet implode?

    as usual, all spam should be reported to spamcop.net, knujon.com, and castlecops.com/sirt :)

    Get these dudes behind bars….

    There’s already investigations going on in NZ regarding some of them….

  • John

    Unbelievable but it does work… and I believe its a big loop whole… I hope google guyz will handle this issue on priority basis…

  • Shady

    Hey Aviram,
    Cool stuff man. Software will have bugs but i dont think that sensitive personal info with Google is so easily available public.

    It works really great…. Maybe the admin guy has known this
    bug [maybe thats why he is SMART ASS] already.. :-)

    Good post….

    Thats the thing about Google, great services but they got all our details. Whether or not you use a false name is unimportant. They have our IP address, our search histrory – a record of everythinng we have done on line.
    I am sure this is just one of the many flaws we will find out about from the Google machine.

    I reported this to Google back in March, and then again in April. Neither times did I get a reply, so I tried posting it to bugtrap, that got no reply, so I posted it on my blog and on Slashdot. My comment on slashdot was voted down out of existence…. now the news is on the front page of Slashdot… grrr!

  • http://www.byteburn.com Arthur

    Gmail has pretty effective anti-spam mechanism that’s why I don’t get obscure gmail addresses from my inbox. Nice find though!

  • l a

    Andrew Brampton…sorry to hear that no one was listening, but usually it only happens if you have a pen at one of these slashdot type websites or blogs, where they are linked to a multitude of other websites….next time if u want to post on slashdot, comment to commander taco about it, he usually listens and sets up a new article if interesting enough

    The same thing does happen with google maps when you invite someone to a map.

    Awesome, thanks! I had wondered who had the gmail account I wanted, and I just found his/her name this way. The person did not have a Google calendar and I chose not to “invite,” but when I saved and went back to manage calendar, there was the name.

    Think about a gmail account you want to hijack.
    Now that you know the person’s name, how hard is it to find out his “mother’s maiden name” , “first phone number” , “first teacher’s name” in FaceBook/LinkedIn/Google?

  • jason ross

    heh. now i know why i got a shared calander message from ‘aviram jenik’. coulda just asked for my name , i’m not keeping it a secret ;-)

    Using Google Calender worked perfectly, thank’s for providing this tool to locate “the one armed man” who is haunting my paranoid ex-sister.
