Muskogee City County Enhanced 911 Trust Authority (“MCC911”) confirmed yesterday that it experienced a ransomware attack earlier this year. According to a press release, MCC911 first detected unusual system activity on July 25, 2024 that indicated they had been the victims of a ransomware attack.
MCC911 immediately began an investigation and took steps to contain the situation, including by proactively taking certain systems offline, changing passwords, notifying federal law enforcement, and engaging cybersecurity and privacy professionals to assist. In addition to the steps taken described above, MCC911 also added measures to improve the security of systems and practices, including implementing endpoint and monitoring tools, updating the firewall, introducing geolocation restrictions, and reconfiguring resources to provide additional protections. MCC911 worked diligently to complete its investigation, bring systems back online as quickly and securely as possible, and add further technical safeguards to existing protections.
Their investigation found evidence of unauthorized access from April 4, 2024, through July 31, 2024.
While there is currently no indication that the unauthorized actor has misused any information for identity theft or fraud in connection with this incident, MCC911 is providing this notice to all individuals who may be potentially affected by this situation, which potentially includes anyone who received emergency medical services in Muskogee County, Oklahoma from January 2011 through April 2023.
They did not explain why unencrypted protected health information (PHI) and personally identifiable information (PII) going back to January 2011 was stored as it was, but the following types of information may have been impacted: name, address, date of birth, Social Security number, diagnosis/condition(s), medication and/or treatment information, medical procedure(s), hospital provider name, health insurance information.
The press release makes no mention of any complimentary mitigation or monitoring services, but offers some advice on how people might protect themselves. There is no substitute notice or additional information on MCC911’s website as of publication.
The threat actor or group was not named in their press release, and no ransomware gang has claimed responsibility for the attack or leaked any data so far, it seems.
