Potential DDoS Event

We have been informed by industry and law enforcement sources of a threat event which may begin on Tuesday, May 7, and which may target the websites and systems of more than 100 U.S. financial institutions and federal agencies. The perpetrators are said to be international activist groups who intend to launch a widespread Distributed Denial of Service Attack (DDoS).  It is unknown which, or how many banks and government entities will experience any issues as a result.

The objective of a DDoS is to temporarily inconvenience the users of targeted entities’ websites and network systems by flooding them with extremely high volumes of internet traffic sent from thousands of computers located around the world. The intense traffic flood can temporarily overwhelm systems, interrupting normal access to websites, online banking services and other processes.  It is NOT the objective of a typical DDoS to “hack” into internal systems for financial gain or access to information, rather, their goal is to cause service interruptions.

Arvest Bank has implemented numerous measures to reduce the possible impact of a DDoS and we are monitoring internet traffic and system performance very closely.  Even so, adverse effects are possible and would be dependent upon the severity and complexity of the DDoS.  Possible impacts could range from sluggish or unresponsive web pages, to website outages and delays in certain transactions which are dependent upon network connections to other entities.

Is this why the regular format doesn't appear on my screen? This has been happening since Sunday, May 5. I can access my accounts, but it's not in Window format.
