Nine Ways Cybercriminals Can Compromise Business Communications

Nine Ways Cybercriminals Can Compromise Business Communications

First of a two-part series

Cloud-based VoIP solutions deliver greater flexibility of your communications resources but because VoIP phones are network devices, they can leave you exposed to many of the same security threats facing your computer systems.

These threats can be serious and costly. Cybercriminals have learned how to hack VoIP phones to gain unauthorized access to voice networks. Once in, they can steal your information and services, burden you with huge, unauthorized bills and disrupt your most important business activities.

Nine Ways In

Fighting off these cybercriminals isn’t easy. The bad guys have developed many effective ways of compromising communications networks. We’ve identified 9 of the most serious threats:

  • 1. Unauthorized calls: Cybercrooks can intercept incoming calls to your VoIP phones, then use their network addresses to make unauthorized outgoing calls.
  • 2. Attacks and fraud: Unauthorized users who gain access to your network can deluge the communication infrastructure with unauthorized traffic and conduct costly toll fraud.
  • 3. Eavesdropping: Hackers can listen in to your VoIP network by intercepting its packet flow.
  • 4. Degraded voice services: When your data service is attacked, voice quality can be reduced to a whisper.
  • 5. Spoofing: Attackers can spoof IP addresses by tricking a network element into believing that their intruding IP packets originated from a trusted host.
  • 6. Unauthorized users: Intruders, thieves and others can log onto networking servers and routers.
  • 7. Hardware failures: Attacks can bring down network infrastructure, preventing your staff from communicating and working.
  • 8. Telephone Denial of Service (TDOS): Debilitating attacks that overwhelm telephone networks, including public emergency systems.
  • 9. Attacking from other networks: The borders between your communications network the public switched telecom network can leave you vulnerable.
