LITTLE ROCK — Arkansas’ largest bank warned its customers Tuesday about an email phishing scam first launched over the Memorial Day weekend.

The scam continued Tuesday, according to a statement on the website of Fayetteville-based Arvest Bank.

The bank said at least two waves of bogus emails purporting to be from Arvest have been distributed, the first with the subject line “Unsuccessful Password Reset!” and the second with the subject line “Arvest Online Banking — You have 1 new Security Message!”

The emails include a link to a site designed to look like an Arvest website, where visitors are asked to provide confidential information.

“We would not do that,” said Jason Kinsey, marketing director for Arvest. “Anytime a customer gets something (unsolicited) that is asking for personal data, they should always be very wary.”

Kinsey said the scammers apparently have been sending the emails blindly, in the hope that some recipients will be Arvest customers and will fall for the ruse.

The bank said anyone who has received a suspicious email supposedly from Arvest, and has not provided confidential information, to forward it to reportfraud@arvest.com. It said any Arvest customer who has provided confidential information should call the bank at (866)931-9743.

Arvest operates more than 200 bank branches in Arkansas, Oklahoma, Missouri and Kansas. Its assets exceed $11 billion.
