The Marriott breach is notable for the large amount of personally identifiable information (PII) stolen, including passport numbers, which increases the risk of identity fraud. The breach was discovered nearly three months after it occurred, highlighting the challenges in detecting such incidents. The impact of this breach will be significant due to the demographics of those affected, many of whom are likely hotel reward members who have not implemented robust password management strategies. To protect oneself, it is recommended to sign up for credit monitoring, use a password manager, activate two-factor authentication, and minimize password reuse. Given the potential for the stolen data to be exploited by cyber attackers, it is essential to review one's personal security posture and take proactive measures to mitigate the risk of identity theft.
