When 911 Goes Dark: How a Cyber Attack Knocked Out Emergency Phone Lines in 5 Towns

This week, a cyber attack disrupted emergency and business phone lines for police, fire, and EMS departments across five Massachusetts towns connected to the Patriot Regional Emergency Communications Center. While the 911 system itself stayed online, the attack left first responders scrambling with degraded communications.

This is not a one-off event. Phone systems, especially aging on-premise PBX systems and poorly secured VoIP platforms, are increasingly targeted by attackers who know that disrupting communications creates chaos.

Why Phone Systems Are Targets

Your phone system carries sensitive conversations, routes emergency calls, and often connects directly to your internal network. A compromised phone system can:

• Intercept calls and voicemails containing confidential business information
• Generate thousands of dollars in fraudulent toll charges through international call pumping
• Serve as a network entry point for lateral movement to other systems
• Disrupt operations entirely, leaving your business unable to communicate

The SIP Trunk Problem

Many businesses still run legacy PBX systems with SIP trunks that have minimal security. Default credentials, unencrypted signaling, and no intrusion detection make these systems easy targets.

Even modern cloud-based phone systems are not immune. Cisco just disclosed that the ShinyHunters group breached their systems using voice phishing. Attackers called employees pretending to be IT support and tricked them into handing over credentials.

How SonicVoIP Protects You
