Every year the number of PBX fraud victims increases dramatically. More and more companies are targeted by individuals who are looking to bring down or exploit the communications system. Some do it for fun and others for illicit profit, but the end result is always the same… Huge bills and down time.

The most vulnerable targets remain small-medium size businesses that are new to managing their own IP PBX system. They either don’t have the IT experience and staff to properly secure and maintain the network, or they’re unaware of the risks altogether having recently switched from a landline system. Whatever the reason, many networks are consistently left unprotected. By the time most companies realize that something is wrong with their phone expenses, it’s too late - the network security has been compromised.

Who Needs an SBC?

If you are deploying an IP PBX system connected to the internet, chances are that it will get hacked within 5h-6h by hackers looking to make calls at your expense or to bring your communication network down just because they can.

  • VoIP became a favorite target for hackers as its popularity and uptake increased in the past years
  • Firewalls are just unable to block hackers who use scripts and bots to access PBX systems
  • The Source address of the hacker is being deliberately spoofed, making it more difficult to detect even more when this one is also masked by the “noise” of many randomly generated addresses
  • A common and devastating attack is the DoS (Denial of Service). PBX systems are unable to handle the flood of SIP requests generated by the hackers. These thousands of simultaneous requests brings your PBX down
  • Brute force password guessing can have the same impact as a DoS attack

And these are only a few attacks out of the thousands used by hackers worldwide. Would you leave our home unlocked? So then why leave your PBX open? Most hackers today, are after the money; so they commit what is known as toll fraud. They access your PBX and use your accounts to place long distance calls or other chargeable calls.
