Clymene Management Services, LLC (CMS) has notified an individual that it detected suspicious activity within its computer network on January 9, 2025. After securing its systems and launching an investigation, CMS determined that an unauthorized actor had accessed its network between January 9, 2025, and January 12, 2025, and that files containing personal information may have been viewed or copied during that window. This is a case of hacking or system intrusion, and CMS says it notified federal law enforcement and is cooperating with their investigation while reviewing its security policies to prevent similar incidents.
The letter is addressed to a specific individual rather than the general public, and the copy provided to us does not include an aggregate figure for how many people were affected overall. CMS states that its review confirmed information related specifically to this recipient was contained in the files the intruder may have accessed.
What information was exposed?
- Specific data elements not identified in the notification letter provided to us (the letter used a placeholder that was not filled in for this recipient’s specific data types)
As a precaution, CMS is offering complimentary credit monitoring, identity theft protection, and identity restoration support through Experian IdentityWorks. You can enroll at https://www.experianidworks.com/credit using the activation code included in your individual letter, and enrollment must be completed by October 31, 2025 at 11:59 pm UTC, after which the code will no longer work.
What should you do now?
- Enroll in the free Experian IdentityWorks credit monitoring and identity restoration services before the October 31, 2025 deadline, since your activation code will expire after that date.
- Review your credit card and bank statements closely for any charges or accounts you don’t recognize, and report anything suspicious right away.
- Request your free annual credit reports from Equifax, Experian, and TransUnion at annualcreditreport.com to check for accounts opened in your name without your knowledge.
- Consider placing a fraud alert or a credit freeze with the three major credit bureaus, which restricts new credit from being opened in your name without extra verification.
- Because the exact types of data exposed weren’t specified in this copy of the letter, treat the situation as potentially involving sensitive information and consider signing up for a service like Aura or LifeLock, which can alert you if your information appears elsewhere.
- Keep the letter and any correspondence with CMS or Experian in case you need proof of eligibility for identity restoration assistance later.
- Watch for phishing attempts that reference this breach, since scammers sometimes use real breach notices to trick people into giving up more personal information.
