Protect your business from Toll Fraud

Why should you care about toll fraud?


Phone fraud is becoming a real problem in the UK, costing businesses £953 million. It can result in bill shock and loss of service, which can be disruptive to your business operations. According to a survey commissioned by ITSPA which surveyed 1,000 businesses across the UK, 27% had been hacked in the past five years, costing each business £12,000 on average.


Phone fraud has become more sophisticated and is a growing concern for many businesses. There are three types of fraud attempt:

  • Unauthorised calls by individuals with physical access to your PBX system. You should therefore ensure that the PBX system is held in a secure place where only authorised employees have access.

  • Malicious disruption - hackers who deliberately manipulate tools, not for fraudulent reasons but because they want to cause mischief and/or to exploit security systems.

  • Organised crime - sophisticated hackers who are looking to generate money quickly.

How do they succeed?

  • Hackers scan the internet looking for IP addresses and also Private Branch Exchanges (PBX’s) with security weakness or which haven’t been configured properly.

  • Hackers will typically target holiday seasons such as Christmas, Easter and bank holidays when the office is quieter or closed for a longer period of time.

  • The time period 2am - 6am is particularly popular as most businesses will not be operating as normal and fraudulent activity is more likely to go undetected.

The most common losses

  • Compromised PBX - hacking of PBX and setting up of premium rate/international numbers

  • Calls made from elsewhere using SIP credentials

  • Calls made from VoIP accounts using stolen credit cards


Where does fraud come from?


PBXs are all IP connected therefore it can occur from anywhere in the world, but generally exotic locations such as the Middle East and Central Africa.


Phone fraud is a concern for all as costs can quickly accumulate. Therefore you need a knowledgeable and proactive supplier to support your organisation in mitigating the risk of telecoms fraud.
