Telecom fraud continues to grow and evolve. Each year, it costs billions of businesses worldwide. As organisations rely more on VoIP and mobile networks for communication, they are highly vulnerable to sophisticated fraud attacks. SIM swaps, vishing, robocall scams, and more.
Common Types of Telecom Fraud
- SIM Swap Fraud
SIM swap fraud happens when a criminal persuades a mobile provider to transfer a legitimate user’s phone number to a new SIM card. Once the swap is complete, the attacker gains control of calls, texts, and two-factor authentication codes, often leading to unauthorised access to bank accounts, apps, and corporate systems. - Vishing (Voice Phishing)
Using social engineering techniques, Vishing involves fraudsters using phone calls to trick individuals into revealing confidential information. Callers may pretend to be from IT departments, banks, or legitimate government agencies to pressure users into sharing passwords, security codes, or access credentials. - Robocall & Toll Fraud
Robocalls (automated phone calls) are often used for spam, phishing, or toll fraud. In toll fraud, attackers manipulate PBX or VoIP systems to make international calls at the expense of the business. These attacks can lead to thousands of pounds in losses overnight if they go undetected.
Our Fraud Monitor service works around the clock to keep your telecom systems secure. By continuously analysing your call traffic, the system builds a unique profile of your typical usage, making it easier to spot anything unusual. If suspicious activity is detected, our team is notified straight away. The affected lines are automatically suspended while we investigate, and where possible, we’ll apply a temporary call divert to keep your business running. Once we’ve confirmed everything is safe, your lines are reactivated without delay. However, while fraud prevention tools like our Fraud Monitor are essential, internal awareness plays a big role too. We always recommend:
- Educating staff on the signs of social engineering
- Using two-factor authentication (where possible)
- Restricting unnecessary international or premium-rate calls
- Keeping PBX and VoIP systems secure with strong access controls
