Home Depot has been investigating a possible breach to their systems in which customers credit cards would have been compromised. Brian Krebs reported on this on his site, where he stated, “Multiple banks say they are seeing evidence that Home Depot stores may be the source of a massive new batch of stolen credit and debit cards that went on sale this morning in the cybercrime underground.” Home Depot is currently investing and cooperating with law enforcement.
It has been reported by Kerbs that Home Depot could have possibly been compromised since May until now. At the moment Home Depot has not confirmed if this is the case or not, and will be contact their customers shortly to inform them of what courses of action should be performed. In the mean time, if you have shopped at Home Depot it would be wise as always to monitor all credit cards you may have used for any suspicious activity.
When more information becomes available I will post an update on the security issue.
