Specialty retailer of hard-surface flooring Lumber Liquidators has reported a network security incident that disabled its certain corporate and store systems across the US.

The incident was first found on 21 August, when the retailer identified symptoms of malware on its network and computer systems.

Lumber Liquidators took immediate action to contain the incident and asked its IT team to diagnose and begin remediation processes, in order bring the company’s operations back to normal.

“I would also like to thank our customers for their patience and understanding during this event.”

According to the company, the investigation remains ongoing and it has not discovered any loss of sensitive and confidential consumer or employee data to date.

The company noted that it secures and maintains most of the customer and employee data, customer credit card information on systems outside of its network.

The company has also resolved customer-related issues of the incident, as well as restored its store operations allowing customers to transact using normal point of sales systems.

The retailer is currently in early stages of broader recovery efforts and forensic analysis, which are expected to continue for several weeks.

Lumber Liquidators president and chief executive officer Dennis Knowles said: “Our diligent work over the past several years to develop system redundancies and business continuity plans paid dividends that were made apparent in our ability to remain open while working to restore our systems.

“We used manual workarounds to facilitate transactions and brought in outside resources to help ensure we returned to normal operations as soon as possible, but I would also like to thank our customers for their patience and understanding during this event.”

Lumber Liquidators currently operates 416 locations across North America, offering more than 400 types of floors in various styles and materials.
