Macworld.com – The leader of a security research firm and AT&T traded angry words Monday in the wake of last weekâs data breach that exposed the e-mail addresses of 114,000 iPad 3G users. The carrier called the behavior of Goatse Security âmalicious,â while the security firm countered that AT&T was âbeing dishonest about the potential for harm.â But both sides have plenty to answer for in how theyâve handled this security situation.
