Senior Constable Paul Litherland of the Technology Crime Investigation Unit warned businesses to "remain extremely vigilant" to ensure attempts to attack their online telecommunications networks are unsuccessful, as the Police are relatively powerless to prevent the fraud.

"As these criminals are working overseas and using quite elaborate methods to avoid detection, Western Australia Police find it difficult to identify or prosecute the persons responsible," the law enforcement agency said in a statement.

Litherland said business owners should:
- Change passwords and prefixes that cannot be easily guessed, (Exetel-yes)
- Place caps on the number of calls that can be made over any given period. (Exetel-yes)
- Bar calls to international locations the company does not contact. (Exetel-available on request)
- Have systems in place to detect suspicious activity.(Exetel-yes)

Exetel implements a number of security and anti-fraud measures to protect customers. These are a mixture of automated systems and business practises designed to limit the exposure to fraud opportunities. However as effective as these measures are, vigilence is still the best form of security.

Exetel is happy to assist any customer in strengthening their systems against fraud. If you have any questions, please email them to either or
