To our Valued Customers:
Beginning at 6:45 a.m. on Sept. 27, 2012, PNC's Internet connection experienced sustained attacks that flooded our Web sites with an extremely high volume of electronic traffic from thousands of locations around the world. This flood of traffic, commonly known as a distributed denial of service (DDoS) attack, was intended to crowd out legitimate customers at PNC's Web sites, preventing them from accessing online banking and other Internet-based services.
The attack on PNC continued for 31 hours, ending on the afternoon of Sept. 28. Our employees worked around the clock to restore service to our customers. While the attack was not a result of any action taken by PNC, we regret that you were affected. We want you to know that our customers will not be responsible for PNC-assessed fees or penalties resulting from the unavailability of PNC systems during this event.
We would like to provide you with some insight into the circumstances surrounding this event:
We continue active engagement with law enforcement, regulators and industry groups in an effort to fully analyze the technical aspects of this attack as we seek to enhance our capabilities. We appreciate the great responsibility you entrust to us, and we are committed to working with you to retain your confidence.
Please feel free to call us at 1-888-PNC BANK or visit a convenient branch location with any concerns you may have. We will do our best to answer all of your questions.
