"Sources now tell KrebsOnSecurity that in a conference call with financial institutions today, officials at MasterCard shared several updates from the ongoing forensic investigation into the breach at the nationwide home improvement store chain. The card brand reportedly told banks that at this time it is believed that only self-checkout terminals were impacted in the breach, but stressed that the investigation is far from complete."
Krebs also says sources say Visa and MasterCard have been reporting fewer compromised cards than expected.
Earlier reports regarding Home Depot's breach, which was first made public on September 2, indicated that the breach impacted all 2,200 of the company's US stores.
Home Depot hasn't commented since issuing a statement on September 8 that gave little color regarding details, saying only that it was "investigating a possible breach of our payment data systems."
Home Depot spokeswoman declined to comment to Krebs, saying only, "Our investigation is continuing, and unfortunately we're not going to comment on other reports right now."
In afternoon trade on Thursday, Home Depot shares were up 1%.
