SAN FRANCISCO (1/15/08)--U.S. Central CU, Lenexa, Kan., is working to prevent phishing attacks after being targeted by a phishing scam last summer. In June 2007, U.S. Central was attacked by the Rock Phish organization. “Within the first few hours of that first attack, we knew we had to do something fast,” said Jean Golka, information technology risk manager for U.S. Central. U.S. Central is one of many credit unions that has been attacked by phishers. Many phishers have improved their technology by hiring automated search or botnet vendors and using tools to make phishing more resilient, so attacks on financial institutions have become more frequent, the credit union stated in a press release. Credit unions were the target of 32.6% of phishing attacks in the third quarter of 2007, according to data from MarkMonitor, an anti-phishing technology vendor that U.S. Central partnered with in June after the Rock Phish attack. U.S. Central has 32 member corporate credit unions, comprising the Corporate Network, which provides liquidity, lending and payment services. The Credit Union National Association also provides anti-phishing technology to assist member credit unions, such as Perimeter CounterPhish.
