Protect your business from telecom fraud

A total of 3.8 million frauds and two million computer misuse offences were recorded by the Crime Survey for England and Wales.

PABX fraud reaps close to £30 Billion for criminals and terrorists. An average incident can cost in the thousands. Holiday periods, such as Easter, can be a vulnerable time for many businesses with reduced staff levels and less opportunity to spot the signs of fraud in time.

Customer checklist

A senior manager should be aware of these safeguards and ensure staff follow them as relevant.

  • Passwords and access codes should be changed regularly and if possible be alpha/numeric and as many digits as the system allows. Avoid 0000, 1234, extension number=PIN passwords.
  • Delete/change passwords for ex employees.
  • Consider limiting call types by extension, if an extension user has no requirement to ring international/premium rate numbers then bar access to these call types.
  • Secure the system physically, site it in a secure comms room and restrict access to that area.
  • Regular reviews of calls should be carried out to cover analysis of billed calls by originating extension also to identify irregular usage and unexpected traffic.
  • Ensure you fully understand your system’s functionality and capabilities and restrict access to those services which you do not use.
  • Mailboxes – block access to unallocated mailboxes on the system, change the default PIN on unused mail boxes.
  • Be vigilant for evidence of hacking – inability to get an outbound line is usually a good indicator of high volumes of traffic through your system. Check for calls outside business hours.
  • Assess security of all PBX peripherals/applications: platform, operating system, password and permissions scheme. Carefully evaluate the security of any onboard remote management utility (eg PC Anywhere) for possible holes.
  • Check firewall logs weekly.
