AT&T Inc. has acknowledged a security weak spot that exposed the e-mail addresses of apparently more than 100,000 users of Apple iPad.
The breach could make those people vulnerable to precision-targeted hacking attacks.
The vulnerability, which AT&T says it has fixed, only affected iPad users who signed up for AT&T's "3G" wireless Internet service.
It involved an insecure way that AT&T's website would prompt iPad users when they tried to log into their AT&T accounts.
The hacker group that claims to have discovered the weakness -- the group calls itself Goatse Security -- said it was able to trick AT&T's site into coughing up more than 114,000 e-mail addresses, including those apparently of famous media personalities and important government officials.
