Is Your VoIP system at risk of being hacked? Learn how to detect the signs

Posted on Wednesday March 01, 2023

Voice over Internet Protocol (VoIP) systems have become an essential part of modern communication for businesses of all sizes. These systems use the internet to transmit voice and multimedia messages, which makes them vulnerable to hacking attempts. Cybercriminals can use a variety of methods to hack into your VoIP system, including eavesdropping, call hijacking, and toll fraud. If your business relies on VoIP, you must be aware of the signs of hacking and other VoIP threats. In this article, we'll explore how to know if your VoIP system is being hacked and what steps you can take to prevent it.

Sudden increase in call volume and bills

One of the most common signs of VoIP hacking is when there is an increase in the number of unauthorized calls made from your system. Hackers can use your VoIP network to make long-distance calls or calls to premium numbers, which can jack up your VoIP bills.

Strange messages or notifications

If you receive strange messages or notifications asking you to verify your banking and other personal information, this could be a sign that your VoIP system has been compromised.

Random antivirus notifications

If you start receiving messages about viruses on your system, do not click on them. Fake antivirus warnings are scams designed to steal data from your device. As soon as you see these malicious alerts, contact your VoIP provider immediately so that they can take action and protect the safety of all of your information.

Redirection to unwanted or fraudulent sites

If you're conducting an online search and you’re suddenly diverted to unfamiliar web pages, it's a sign that your VoIP system is under attack. Also, if you find your browser is automatically downloading extensions or toolbars without your permission, it's a sure sign that your system has been compromised.

If you suspect that your VoIP system has been hacked, you should contact your VoIP provider or IT team immediately and take steps to secure your system. This may include changing passwords, implementing stronger security measures, and monitoring your system for other suspicious activity.
