Company Reportedly Investigating Misconfigured System As Cause

Sophos Warns Customers of Possible Data Leak

Security firm Sophos is warning that some of its customers may have had their data exposed due to a misconfigured internal system, according to a published report.

On Tuesday, the U.K.-based firm sent a message to customers noting them that because of an “access permission issue in a tool used to store information on customers who have contacted Sophos Support,” some data may have leaked, according to a report in ZDNet, which obtained a copy of the notification.

The data that possibly leaked included customers’ last names, email addresses, and phone numbers, according to the report. In a message to Information Security Media Group, a company spokesperson confirmed the incident and noted that only a “small number” of customers were affected by the incident.
