- Recovery Actions: Settled the class-action lawsuit; distributed settlement terms (\$1 credit via manual claim codes like `P@rkMobile-$1`); issuing public warnings regarding ongoing phishing scams.
## Lessons Learned
- The security practices in place prior to 2021 were deemed inadequate by the class-action plaintiffs, indicating potential failures in data protection protocols.
- A substantial data breach resulting in millions of compromised records can lead to significant legal and financial repercussions, even with settlement denials of liability.
- Post-incident follow-up (like phishing campaigns) continues long after the initial event is contained and must be actively monitored.
## Recommendations
- Implement robust data protection measures, particularly for handling PII, passwords, and vehicle/license plate data.
- Review and strengthen password hashing mechanisms if current standards are found lacking in post-incident review.
- Establish clear, proactive communication channels to warn customers immediately and continuously about related phishing/smishing activities following a breach.
- Ensure settlement compensation mechanisms are straightforward and minimize the burden on affected users.
