Recommendation: The exposure of Personally Identifiable Information (PII) requires affected individuals to take precautionary measures to protect their identity and their finances. Identity theft services can assist in preventing illicit purchases, or applying for financial services from taking place by actors using stolen data. It is crucial for your company to verify that access control is configured correctly prior to adding any sensitive data. As this story portrays, a misconfigured database has the potential to cause significant harm to individuals and a company’s reputation.
