KANSAS CITY, Mo. -- Several people who went online Friday to do some banking wound up victims of a scam, officials said.

Community America Credit Union confirmed to KMBC that a hacker managed to redirect people from the company's Web site to a phony site.

Community America said it caught the intrusion within a few minutes, but about a dozen people accessed the phony site. The company said it is contacting the victims.

"I was one of the victims that got stung, for lack of a better word," Brian Walker told KMBC.

The 37-year-old from Johnson County, Kan., logged on to the credit union's Web site, but said he was immediately redirected to a phony site, which is called pharming.

"Same logo as the bank, same everything. It asked for my card number, ID number, Social Security number, all my information, so assuming it was through Community America, I gave it all my information," Walker said.

He said nearly $500 is already missing from his account.

"We found out it was actually overseas where this money was taken out. It was actually in Russia," Walker said.

Walker said his money was refunded, but he's still worried about identity theft.

"(Community America) immediately credited back the money once they discovered the problem," he said. "I'm anxious. I'm going to be watching my credit reports, watching all my information, doing a lot more hands-on banking than online banking."

Community America said no one had access to its computer.

Experts said that legitimate financial institutions will never ask for credit card numbers, Social Security numbers, date of birth or personal identification numbers. Bankers said it's important to check your account regularly for problems.

Note: An earlier version of this story stated that 180 customers were affected by the scam. Community America said about 180 people viewed the phony Web site, but only about 12 people gave out their information. We regret the error.
