The City of Marina has notified individuals that an unauthorized person gained access to some of its computer systems between August 19 and August 20, 2025, and copied files stored on its servers. The city says it identified the unauthorized activity on August 20, 2025, moved quickly to secure its network, launched a forensic investigation, and reported the matter to law enforcement. This type of incident is classified as a hacking or system intrusion, meaning someone outside the organization broke into internal systems rather than the breach originating from a lost device or an employee mistake.
According to the letter, the city reviewed the affected files and, on December 29, 2025, confirmed that at least one file containing the recipient’s personal information was involved. The notification letter itself does not spell out an aggregate number of people affected, and the version provided to BreachLetter uses a placeholder in place of the specific data elements exposed for each individual, so we can’t state with certainty exactly which pieces of information were in your file. If you received this letter, the specific data types involved should be listed directly in your personal copy.
What information was exposed?
- Your name, along with one or more categories of personal data specific to your file (the source letter template does not spell out the exact data elements for every recipient — check your individual notice for the specifics named there)
Because the city is offering a full identity restoration and credit monitoring package rather than just a heads-up, it’s worth treating this as a serious notice. The city is providing a complimentary 12-month membership to Experian IdentityWorks, which includes credit monitoring, identity restoration assistance, and $1 million in identity theft insurance. To enroll, visit https://www.experianidworks.com/credit and enter the unique activation code included in your letter before the deadline printed there — the code will stop working after that date. You can also call Experian at 1-877-288-8057 for help enrolling or to ask about Identity Restoration support, referencing the engagement number in your letter.
What should you do now?
- Enroll in the free Experian IdentityWorks membership using the activation code and deadline in your letter — it costs nothing and doesn’t affect your credit score.
- Review your bank and credit card statements regularly for charges or accounts you don’t recognize.
- Pull your free credit reports from all three bureaus at annualcreditreport.com and look for accounts you didn’t open.
- Consider placing a free security freeze on your credit files at Equifax, Experian, and TransUnion, which stops most new-account fraud even if your identifiers are misused.
- Since the exact data exposed isn’t clearly stated for every recipient, treat this proactively and consider signing up for a service like Aura or LifeLock, which can alert you if your information appears elsewhere online.
- If you believe you’ve become a victim of fraud, file a report with the FTC at identitytheft.gov and with your local police department, and keep a copy for your records.
