AT&T is issuing a blanket apology for the security breach that uncovered the emails of tens of thousands of iPad owners. The telecom said that hackers “maliciously exploited” a network ability to obtain ICC-IDs of AT&T SIM cards for the iPad 3G and their corresponding email addresses.

This incident uncovered the fact that several prominent people use the iPad, including executives at Google, Amazon, Microsoft and high ranking personnel in the U.S. Senate, Department of Justice and FCC. AT&T says that the security hole has already been plugged.

For its part, the group that uncovered the exploit said AT&T “is being dishonest about the potential for harm” from the security hole it has exposed.
