Can a Yahoo profile be hijacked?

I have owned a Yahoogroups email list for several years. One of the members recently started "bouncing". She went to the group's site and clicked on the little message that said find out why you're bouncing. She was taken to what was apparently her profile, only it had been changed. Her first name had been removed so that her maiden and last names were left (which could easily be a male first name/last name.) It said she is a 23-year-old male (she is much older than 23), and there was an additional email address listed in besides her correct one. That one was a Hotmail addy.

I am concerned that my private email list may have been breached in some way.

Thanks for any information.

Yes, this can happen. People keep trying passwords until they find out yours and then they change some onfo so that they also can get addresses from the list and use them for spam , ( which they sell to other spam marketing companies). The best thing is to log in , change your password to a combination of letters and numbers ( alternate) and then correct all your information.
Yes if they find your password and user name. Thats all it takes to access it. I suggest start a new one and delete all in the old one then never use it again and be more careful next time.
Yes. Password and ID will be needed. You have to sign in to change profile. You can have several profiles. You can have several email boxes. Your group settings can hide all group members from public. My assumtion= Done his/her self. Unless password is public knowledge. EMAIL LISTS= Transfer my email list to Yahoo! Groups

It's easy, just follow these steps:

Gather all the email addresses for your group members.

Arrange them in a text list, one per line.

Register with Yahoo!, if you haven't already done so.

Start a new group -- you'll find a button on every page of the Yahoo! Groups web site.

Once you've set up your group, go to the Members section of your group and click on the Invite Members link.

Follow the instructions to invite people to your group. For more information on how to invite members, please refer to the Members help section.
