Phone System Hackers Leave Small Businesses With Big Bills
by Don Fosen on Nov.11, 2009, under Security Updates
Hackers are expanding their attacks to phone systems across the nation. They will dial in, often with automated programs, and attempt to access the administrative interface of the phone system. They will then give themselves the capability of dialing international numbers. Many VOIP (voice over Internet protocol) based phone systems are also vulnerable through their Internet connections.
How do you protect your phone system? Here are some things to do:
- Make sure default passwords are changed
- Put a good firewall solution in front of any VOIP solutions
- Review phone bills carefully for any odd calling patterns
- Have a qualified vendor conduct periodic security reviews
