Gartner surveyed 5,000 online consumers last March. 30% of respondents had identities stolen online. 90% of those cases were in the last year, and 70% occurred since September, 2003. In the second half of 2003, only 4% of hacker attacks were launched at e-commerce sites. In the first half of this year, 16% were targeted at e-commerce, making it the single most assaulted industry, according to Symantec.
