Posted on Wednesday January 06, 2021Theft of service is the most common type of fraud that impacts Voice over Internet Protocol (VoIP) phone systems. Let's take a closer look at how it affects VoIP networks and how your organization can prevent or minimize the risk of this type of fraud.
VoIP theft of service is the most common type of VoIP fraud. At its most basic level, it involves the theft of your organization's VoIP account credentials, including usernames and passwords, either by eavesdropping or by introducing malware into your system. Once cybercriminals gain access to your account, they can freely make phone calls or change your call plans, running up your VoIP bill.
In addition, cybercriminals may use the stolen data to carry out other fraudulent activities. They can also use theft of service to flood your VoIP network with promotional calls similar to junk email via an attack called spam over internet telephony, or SPIT. Once they infiltrate your communications network, they might broadcast unsolicited messages or advertisements over your VoIP system. This keeps users from making or receiving calls, which can have a significant impact on your business's operations.
Preventing VoIP theft of service simply requires using a little common sense and implementing some technical preventive measures.
