Merry VoIP Fraud!
The holidays are approaching. That means it’s time for family, shopping, turkey, and VoIP fraud.
That’s right folks. The holidays present a great opportunity for fraudsters to take over business phone systems. Early morning and weekends, when people are not working, are also popular times for VoIP fraud.
Time off is an important time to get some R&R. But when you return to a giant and unexpected phone bill, it can provide a real wakeup call on the need to watch out for VoIP fraud at all times.
That’s what happened to Bob Foreman a few years ago. Hackers broke into the phone system of his architecture firm and rang up $166,000 in charges.
They did that by routing calls from the company’s system to premium-rate telephone numbers in Gambia, the Maldives, and Somalia. As The New York Times reported, it would’ve taken the Norcross, Ga., firm 34 years to amass these kind of charges.
This scenario is not all that unusual. Bosnia, Cuba, Estonia, Lativa, and Somalia are common sources of toll fraud. And fraudsters frequently breach business phone systems to support premium-rate numbers like those used by psychics and for sex chat operations.
Once a hacker breaks into a PBX (News - Alert) or other phone system, they can make loads of calls to an array of far-flung locations. And VoIP technology enables bad actors to breach a single extension and then add more channels to provide the ability to support even more calls.
There are a few things your business can do to prevent this kind of thing. It can review its call logs regularly in an effort to identify unauthorized activity. Better yet, it can employ a monitoring and alert system to inform you of abnormal or suspicious activity on your system.
It can leverage session border controllers and SIP firewalls to filter suspicious packets. It can restrict access to known entities. And it can remove unused devices from accessing your phone system.
