Signs That Your VoIP System Has Been Hacked

When most people think of hacking, they think of phishing emails and computer hijacking. Very few people consider that their phone systems could be hacked. However, VoIP hacking is possible and fairly common, so it’s important to be able to identify the most common signs of a hacked VoIP system. The more quickly you can identify these signs, the more quickly you can notify your managed IT services provider and save your company’s money and data.

Sudden Increase in Bills

When hackers get into a VoIP system, they’ll likely begin to make calls to premium-rate phone numbers using your line. This will result in a significant increase in your monthly phone bills. If you haven’t added any new phone lines or numbers, then your bill should stay about the same month-to-month. If you notice a sudden rise in your bill, you should alert your phone provider as it’s likely that someone has hacked your system and is making unauthorized calls. 

Antivirus Pop-ups

Another sign of a VoIP hack is if your employees suddenly receive pop-ups for antivirus software on their computers. Since VoIPs use your Internet network to connect to devices, hackers can utilize this to create phishing notifications on a corporate computer when the VoIP system is on. If one of these antivirus pop-ups appears, warn employees to never click on it. Notify your managed IT services provider, such as C3 Tech, and they will shut down the network to scan for any malware.

Irregular Call History

Similarly to an increased phone bill, another sign of a hacked VoIP system is an irregular call history. If you suspect that your VoIP system has been hacked, you can ask your IT services provider for a call history report. Identifying any unknown numbers or suspicious locations will help you figure out whether your devices have been hacked, although this will likely need to be confirmed with the support of another indicator such as increased phone bills or suspicious computer activity.

Webcams Turn On Automatically

One suspicious computer activity that can be a sign of a hacked VoIP system is webcams or microphones turning on automatically. This is commonly associated with computer hacking, but it can indicate VoIP hacking as well. Hackers listen in on phone calls or conference calls by illegally accessing these devices in order to obtain sensitive or confidential business information. If you notice that your webcam or microphone is acting strangely, it’s always wise to notify your managed IT services provider and allow them to check your system for hacking.
