  6. The Rhysida ransomware group claims it breached the Cheyenne and Arapaho Tribes, demanding 10 BTC after disrupting education and administrative systems.

    Governor Reggie Wassana confirmed refusal to negotiate.

    Rhysida has a history of targeting public-sector networks, including state and municipal infrastructure.

    Technical considerations:
    • Initial access vector? Phishing vs exposed RDP?
    • Backup segmentation and immutability
    • Insurance-driven IR workflows
    • Data exfiltration + double extortion tactics
    • Public-sector attack surface mapping
    Should smaller governments move toward managed detection and response (MDR) as a baseline requirement?

  10. According to Dragos, Volt Typhoon continues active operations inside U.S. utilities, shifting toward direct OT interaction and sensor data theft in 2025.

    Notable elements:
    • Pre-positioning in ICS environments
    • Exploitation of Ivanti & Trimble Cityworks vulnerabilities
    • GIS data harvesting for infrastructure mapping
    • Access broker activity attributed to SYLVANITE
    • Long-term persistence objectives
    CEO Rob Lee stated some compromised sites may never be identified.

    Technical question:
    If adversaries maintain low-and-slow OT access, how should defenders adapt detection engineering?
    – Network baselining?
    – Sensor telemetry validation?
    – Asset-level anomaly detection?
    – Zero trust for OT?
