Data categories reported as exposed include Full Name, Email Address, Password or Credential Hash, Mailing Address, Phone Number, Employment and Professional Title, Corporate Account History, and Internal System Access Logs. The exposure of these specific types of information can lead to various risks, including targeted phishing attempts, unauthorized access to other online accounts, and potential misuse of personal and professional details.
