PNC Bank's efforts to block cyber attackers looking to clog the company's website might be making it even tougher for some customers to get through.
As we reported yesterday, PNC's site has been under cyber attack on and off since December 11th.
The problem grew Thursday, to the point where dozens of irate customers flooded the company's Facebook site with complaints and requests for access.
It's called a DDOS attack, which stands for Distributed Denial of Service.
The idea is to flood a site with so many requests for information that real customers can't get through.
A group calling themselves the al-Qassam Cyber Fighters is claiming responsibility, demanding that an anti-Muslim video be pulled from You Tube.
There is no way to confirm if the group really exists or is behind the PNC attack.
In an email to customers sent Thursday night, PNC Bank apologized for the situation, saying that some efforts to thwart the attacks may have made it even harder for customers to get through.
The Bank continues to stress that the attacks are designed to clog the site only.
PNC says that the company's data bases have not been hacked and no personal information or funds are at risk.
There is no timetable for restoring full access.
