GitHub said on Wednesday it is investigating unauthorized access to its internal repositories following the compromise of an employee's device. 

“While we currently have no evidence of impact to customer information stored outside of GitHub’s internal repositories, we are closely monitoring our infrastructure for follow-on activity,” the developer platform said in a statement.
