Fraudsters are always looking for new ways to target businesses so it can be difficult to fully protect yourself against telecoms fraud, but there are some steps that you can take to reduce the risk.
PBX Fraud
A PBX (Private Branch Exchange) is a phone system that switches calls between users on local lines while allowing all users to share a certain number of external phone lines. Hackers can gain access to your PBX phone and use common system commands such as a 0800 number to get a dial tone. The fraudsters then place long distance calls through the line.
Voicemail Fraud
This is the most common type of telecoms fraud. An unauthorised third party gains access to the phone system via the voicemail menus that are either unprotected or protected by default passwords (0000, 1234 etc.). Long distance calls are then placed and can mount up to hundreds of thousands of pounds.
- If you don’t require premium rates then shut them down.
- Any access codes to log into the phone system should be changed from their defaults.
- Secure your comms room so no unauthorised personnel have access.
- If you are provided with default passwords, remove them and replace them.
- Take the time to understand the phone system and what you are able to do, or not.
- Regularly review call usage, this will alert you to anything suspicious.
- If you have any unused mailboxes, block access to them. This will reduce their vulnerability.
