Home Depot is the potential source of a large data breach, the latest in a string of attacks aimed at large companies. Jim Cramer says he expects the breach will be massive in scope but it will not be anything like Target's credit card breach situation because in the case of Target, the company was being hurt by other factors and it was being poorly run. Cramer says Home Depot will be out in front of this the whole way. He says he would be shocked if people switched from Home Depot to Lowe's as a result, which is why the weakness in Home Depot is a buying opportunity. Shares of Home Depot continued to stay in the red Wednesday.
