Don’t get caught out by Toll Fraud

Toll fraud, otherwise known as phone phreaking, call phreaking or dial-through fraud is on the rise in the UK and has cost some businesses tens of thousands of pounds. The reason: it can go completely undetected until the time of your next phone bill – and suddenly you’re stung with a huge bill that you might not be able to afford.

What is Toll Fraud?

Toll fraud, or phone phreaking, is where a cyber criminal hacks into your telephone system and uses it to make calls to international or premium rate numbers at your expense, the end result being a huge bill.

In the last 3 months 2 our our customers have fallen victim to this crime. Although Concert [1] will never profit from fraud the cost to our customers was still over £10,000.

Imagine the following scenario:

All of your employees leave the office on a Friday at 17:30 and come back on Monday at 09.00. During this time someone hacks your phone system and makes international calls at a premium rate, for example at £1.15 per minute.

In essence this may not seem like very much, but think about how many minutes that call could last while your office is unmanned over the weekend. From 5.30pm Friday to 9am Monday morning is 63.5 hours, thats 3,810 minutes! Now multiply this by the premium £1.15 per minute and you’re already looking at a £4,381.50 bill on top of your usual monthly cost.

Now consider that this is based on the assumption that you only have one phone line. What if you have 5 lines and the same happens to each? Now your looking at £21,907.50 of fraudulent activity!

You can begin to see why toll fraud can be such an expensive and damaging form of cyber crime.

How bad is toll fraud in the UK?

Phone hacking and telecommunications fraud is thought to cost the UK as much as £1.5 billion a year with some individual business seeing bills as large as £ 35,000 and in today’s connected world, every business is at risk of toll fraud.

It doesn’t help that a staggering number of organisations, large and small, have neither the knowledge nor the resources to ensure that their systems, processes and people are protected in the face of this ever changing digital environment.

Is there any good news?

Sort of – there are some ways that you can try and prevent toll fraud.
