Scammers have found a way to exploit vulnerabilities in VoIP (Voice over Internet Protocol) via a scam called vishing. This VoIP phishing scam works much like any phishing attack. A scammer purports to be a legitimate entity and asks the potential victim to provide sensitive information. Learn how fishers operate.
VoIP makes it easy to create fake numbers
More cyber criminals are launching vishing scams because it’s easy for them to hide their tracks and the risk of getting caught is minimal.
Using a fake number, scammers can contact your employees, pretend to be a representative of a bank or government agency, ask for sensitive information — such as salary information, account numbers, and company intellectual property — and get away with it. Scammers can also manipulate local numbers to emulate multinational banks, which they will then use for various VoIP scams.
VoIP phishing: VoIP is easy to set up and difficult to track
It isn’t difficult to configure a VoIP system, which makes it easy to make fraudulent phone calls or messages. Scammers only need to know the basics of a VoIP setup.
VoIP hardware such as IP-PBXs, IP phones, and routers are also inexpensive and quite easy to access. Hackers can conveniently connect these equipment to PCs to record phone calls and steal information from conversations.
Additionally, fake numbers are difficult to track because they can drop at any time. And with advanced voice-changing software widely available nowadays, a vishing scam is much easier to pull off.
Tamper with Caller ID
In some vishing scams, attackers don’t even have to terminate a number to cover their tracks. Instead, they trick users with caller ID into thinking they’re talking to legitimate technical support staff.
VoIP phishing is cost-efficient
Traditional phones are still in use for phishing scams, but they don’t compare to the efficiency that VoIP affords. Which in fact, allows attackers to target victims all over the globe at a fraction of the cost. Cybercriminals resort to VoIP scamming because the price per call is much lower. Vishing scammers are sneaky and resourceful. They will exhaust all possible means to attack your systems for profit — and that includes your VoIP channels.
Protecting yourself is simple
To protect against VoIP-based scams, set stringent policies on information sharing and impose strict security processes for all business communications. All in all, being aware of employees is key to making sure that scammers are held at bay. Protect your company against all types of scams by getting in touch with our experts today.
