## Impact Assessment
- Financial: Potential costs associated with recovery and FEMA grant utilization (specific amounts not detailed).
- Data Breach: Scope of data compromise is unknown, currently under investigation by federal partners.
- Operational: Disruption of necessary critical state services, requiring federal assistance to restore functionality.
- Reputational: Negative impact due to publicized service disruptions.
## Indicators of Compromise
- [Network indicators - defanged]: None specified in the source material.
- [File indicators]: None specified in the source material.
- [Behavioral indicators]: Service disruption of state websites and telecommunications systems.
## Response Actions
- Containment measures: CISA deployed threat hunting teams to assist in mitigating ongoing threats.
