Stack Overflow hacker went undetected for a week

The hacker who breached Stack Overflow last week managed to access data on user accounts, the company said today in an update on its investigation into a security breach it disclosed last night. The update comes to shed some light into what happened on the company’s servers last week, after Stack Overflow left many users scratching their heads when it posted a very short message on Thursday, announcing a severe breach of its production systems. While it initially said that there was no evidence of the hacker accessing user data, the company changed its statement today.

The exec said the company is now reviewing log files to determine which users were impacted by the hacker’s scans. Users found to have had their info viewed or collected by the hacker, will receive a notification, she said.
