According to Arbor Networks - a leading security solutions vendor, last week's DDoS attacks by the terrorists group 'Izz ad-Din al-Qassam' against websites of US financial institutions have peaked at 60 Gbps while, the technique used did not succeed in shutting down the targeted websites completely. Arbor researchers believe that in general major banks and their respective providers are now better prepared to defend against this type of attack. The attacks that took place from Tuesday till Thursday have caused some degradation in services as stated by PNC financial institution "PNC is experiencing an unusual volume of internet traffic consistent with recent threats against U.S. banks. Access to pnc.com, online and mobile banking is slow as we work to resolve the issue."
