Gartner: Phishing Attacks Threaten E-Commerce: Page 2 of 4

Phishing, though not new to the Internet, has exploding in last six months. Since October 2003, 76 percent of all known or suspected phishing attacks were launched. Another 16 percent were sent in the six months prior, meaning that 92 percent of all attacks were conducted in the last year.

"This is an old trick," said Litan, "but it has totally picked up lately."

Phishers do this because they're successful at getting personal information, and using it. "There's a high correlation between victims of phishing attacks and victims of identity theft," said Litan. "A majority of those who remember giving away sensitive information to phishers also reported being victimized by identity theft," she said. Ninety-four percent of that group -- about a million Americans -- said that the theft occurred in the past year.

In the general population of those who say they've been victimized by identity theft, only 36 percent said it had happened in the last 12 months.

"Phishing attack victims are almost three times as prone to fraud as other online consumers," concluded Litan.
