UK operator O2 recently apologized for providing its subscribers' phone numbers to every Web site they visited for the past two weeks.
"The company claimed that changes made during routine maintenance meant that from 10 to 25 January 2012 customers' mobile numbers would have been logged by websites visited by O2 subscribers using 3G or WAP," Infosecurity reports.
"Security experts said the breach meant that website owners could potentially collect the mobile numbers and use them, without consent, for spam or phishing," the article states. "After stalling most of the day by promising to look into the matter, O2 finally said: 'We investigated, identified and fixed it this afternoon. We would like to apologize for the concern we have caused.'"
