AT&T just revealed that
outside attackers — allegedly employees of one of AT&T’s service
providers — stole a trove of personal information on AT&T Mobility
customers. AT&T says the stolen information includes Social Security
numbers and call records, i.e. details about the date, time, duration
and other phone number for every phone call customers make. AT&T
would not disclose the number of affected users.
The AT&T Mobility breach apparently occurred on April 9 through 21,
two months ago, but AT&T only just revealed it now, as a California
state law requires all companies with 500 or more Californian customers
to self-report if they have suffered a data breach.
