Database management giant MongoDB says it’s investigating a security incident that has resulted in the exposure of some information about customers. In an update published on Sunday, MongoDB said does not believe hackers accessed any customer data stored in MongoDB Atlas, the company’s hosted database offering. For one customer, this included system logs, MongoDB said. System logs can include information about the running of a database or its underlying system. MongoDB declined to say how many customers may be affected by the compromise of its corporate systems.
