According to Dell SecureWorks researchers, hacker attacks on retailers have increased by 43 percent since last year.

"During the first nine months of 2011, Dell SecureWorks blocked an average of 91,500 attacks per retailer, compared to 63,651 during the final nine months of 2010," writes SC Magazine's Angela Moscaritolo.

"The rise is primarily due to an increase in SQL injection assaults against servers, as well as attacks stemming from web-based exploit kits, Ben Feinstein, director of operations and analysis with the Dell SecureWorks Counter Threat Unit, told on Tuesday," Moscaritolo writes.
