12 Jan Beware…telephony fraud is on the rise
The UK is the third most targeted country in the world for telephony fraud and telephone hacking. Fraudsters hack into your PBX or hosted telephony, normally out of office hours, and gain access to your phone system in seconds. They use advanced software packages to crack pass codes and bypass firewalls.
Once inside your system, hackers use it to route unauthorised and illegal calls to any location in the world. The stolen call time is sold on as legitimate call time in the form of calling cards and low-priced calling tariffs. In almost all cases there is a link to organised criminal gangs purporting to be legitimate businesses.

Here’s some Steps & Tips To Prevent PBX & Hosted Telephony Fraud
- If you do not call internationally, ensure a restriction or lock down is placed on these types of calls.
- Remove & change all default password settings and limit access to any maintenance ports immediately
- Change passwords and access codes regularly and create stronger and longer passwords using both alpha and numeric. Avoid 000, 1234 and extension numbers.
- Analyse your bills frequently & ensure your business can account for itemized calls.
- Crosscheck calls to international countries & ensure they are to countries you recognise.
- Consider limiting call types by extension. If a user has no requirement to call international or premium rate numbers (PRS) then bar access.

- Assess security of all PBX & Hosted Telephony peripherals and applications: platform, operating system, password and permissions scheme and always evaluate the security of remote management tools (e.g. PC Anywhere).
- Importantly, be vigilant for evidence of hacking the threat is both internal & external, some signs include
- Not being able to obtain an outbound line is a good indicator of high volumes of traffic through your system, if this happens contact your provider immediately.
