SecureWorks reports they have seen a 161% increase in the number of attempted hacker attacks they are blocking for their retail clients. Attempted attacks increased from an average of 56,000 per client per month in the first six months of the year to 133,000 per client per month for the last five months. The attack statistics represent the attack activity for 36 major retail corporations located across the country.

"We saw a large increase in hackers looking for open ports, as well as those trying to identify the applications and other services our retail clients were running," said Wayne Haber, director of architecture for SecureWorks. "An increase in network scans is often a red flag because many times it is followed by attacks specifically targeted at the organization's services," said Haber." "Attempted network scans against our retail clients increased 61% in 2008 going from an average of 56,000 per client per month in the first six months of the year to 90,000 per client per month in the last five months of the year," continued Haber.
