The rise of the internet has been accompanied by the emergence of innovations in communication technology, thereby facilitating everyday communication. One such technology is the use of virtual phone numbers, commonly known as VoIP.
VoIP can be used for low-cost international communication and it powers applications like Skype. However, like every internet-based technology one needs to be cautious with its use.
Hacking is recognized as illegal, however, it also has an ethical variant. Ethical hacking involves companies employing the services of hackers to test their software against security vulnerabilities. However, hacking done for personal gain by individuals or groups continues to pose a threat to online services.
VoIP hacking
VoIP hacking involves access to the numbers system gained by an unauthorized individual. This gives the hacker access to sensitive information and she/he can listen to all communications made by the number. She/he can also access all the services that depend on the number as well as access data that may be transferred with it. Such a hacker can make calls that can run up high bills and make a firm go bankrupt. A hacker can also engage in fraudulent activities like phishing and impersonate or pretend to be a member of your organisation.
Signs that your VoIP number is under attack
- Incoming and outgoing calls in your history that you dont remember.
- Microphones and webcams acting strange: If they are turning on or recording without any input, then someone may be controlling them from the internet without your consent.
- Skyrocketing bills: VoIP services are very affordable, so an expensive bill requires scrutiny of call history.
- Antivirus messages suddenly popping up: These messages act as a warning sign. If these messages appear too often, they indicate the possibility of your device being under attack.
Preventing VoIP numbers from being hacked

- Use a VPN or a proxy if you work remotely: A good VPN or proxy eliminates the problem of unencrypted data by allowing the connection between you and your service to be secure.
- Change your passwords regularly and update any software that you need. If you have a big system, it is always a good idea to have your system tested by an ethical hacker.
- Adopting a two-factor identification process: This consists of adding an extra security layer to ones authentication process. Strong passwords, cell phones or face recognition function as good security factors. The ideal security uses at least two of these factors.
- Trustworthy VoIP provider: A good provider ensures that your number is not compromised. Also, use up-to-date software. The use of a low-quality service also makes your number susceptible to security breaches.
