In Home Depot Breach, Investigation Focuses on Self-Checkout Lanes
Summary: Malicious software used to steal card numbers in the Home Depot breach was installed mainly on self-checkout lane payment systems, according to sources close to the investigation. MasterCard told banks on a conference call that the forensic investigation found evidence of compromise at approximately 1,700 of the nearly 2,200 U.S. stores, with another 112 stores in Canada potentially affected, though the investigation is far from complete.
Why it matters: The breach ran almost five months, yet banking sources say Visa and MasterCard have reported far fewer compromised cards than expected - a reminder that scope and duration do not map cleanly, and that the 1,700-store figure is an interim finding, not a final one.
