A distributed denial-of-service (DDoS) attack targets a VoIP server by overwhelming it with phony user requests. This excessive traffic can exceed the network’s capacity, causing service disruptions and making genuine user requests unprocessable.
Online criminals exploit these attacks to disrupt Voice Over Internet Protocol (VoIP) network services, the backbone of modern business phone systems and customer service software. VoIP services are particularly susceptible to DDoS attacks, as even a failed attempt can significantly degrade voice call quality and reliability.
Modus Operandi of VoIP DDoS Attacks
DDoS attacks aim to overwhelm a network with fake traffic, resulting in service denial for legitimate users. A typical VoIP server managing hundreds of calls per hour might struggle to respond to thousands of requests per second during an attack. Key attack methods include:
- Botnets: Hackers deploy large networks of compromised devices, such as PCs, routers, mobile phones, and IoT devices, to generate attack traffic.
- SIP Flood Attack: The attacker sends numerous Session Initiation Protocol (SIP) call requests, crashing the victim’s VoIP server.
- SIP Reflection Attack: Hackers spoof the victim’s IP address and send queries to random ser
