Minimise your risk and guard against phone fraud and phone hacking

Whether it is via a landline, mobile phone, VoIP or PABX, everyone is at risk of phone fraud. Learn how to minimise your risk and guard against phone fraud and phone hacking.

PABX Fraud

Minimise your risk and guard against PABX phone hacking.

Leaving your PABX (business phone system) unsecured is like leaving your bank account details and access codes pinned to your front door! Security of your PABX is as important as the security of your PC. If you haven't secured your system, it’s relatively easy for hackers to defraud you of thousands of dollars.

If you have any queries regarding your PABX, contact your vendor in the first instance for advice on securing your system.

Minimise your risk and guard against PABX hacking with these tips:

  • Choose a strong password. Avoid factory defaults and obvious PIN combinations like 1234 or 0000.
  • Change PIN combinations and passwords regularly.
  • Always reset passwords following an upgrade, fault or maintenance.
  • Ensure PIN combinations and passwords are secure.
  • Keep all internal information such as directories, call logging reports and audit logs confidential.
  • Ensure you have the right terms and conditions reflected in your contracts with your PABX, VoIP and/or voicemail maintainer in order to keep your system regularly maintained and serviced to stay safe.
  • Remove or de-activate any unnecessary system functionality including remote access ports. If remote access ports are used, strong authentication such as smartcards and tokens is advised.
  • Regularly review your call log for any increase in call volumes or suspicious destinations.
  • Only give appropriate and minimum level of system access required to carry out a task.

VoIP Fraud

If you are using a VoIP service you may be vulnerable to a combination of both computer hacking techniques and phone fraud.

Minimise your risk and guard against VoIP fraud with these tips:

  • Choose a strong password. Avoid factory defaults and obvious PIN combinations like 1234 or 0000.
  • Change PIN combinations and passwords regularly.
  • Ensure PIN combinations and passwords are secure.
  • Ensure remote administration functions on your computer or network is disabled.
  • If you do require remote access, use a secure method to access the network, like a firewall and authentication.
  • Use anti-malware software and keep it updated by scanning regularly.
