Phone fraud has become more of a complex art and is a growing concern for many businesses. The most common types of phone fraud include: unauthorised calls, malicious disruption and organised crime.
Unauthorised calls can be made by individuals with physical access to your phone system. You should therefore ensure that your PBX system is held in a secure place where only authorised employees have access.
Malicious disruption is where hackers purposefully manipulate tools to exploit security systems or out of date of software. Whilst organised crime involves hackers who are looking to generate revenue quickly.
A recent survey of one thousand businesses suggested that over 20% had been hacked in the past five years, costing in excess of £10,000 per business.
