Keep Your Hacker Hands Out of My Phone System
Category : VoIP Security
If you are an OfficeSuite Phone customer and read the New York Times article Phone Hackers Dial and Redial to Steal Billions you might be in a panic, worried how to protect your business from such a scam.
But don’t worry, Broadview has your back.
The scam or hack mentioned in the article involves people calling into a phone system’s voicemail service to make outbound calls. While this feature is convenient for some, it poses a huge risk as most passwords are easy to guess (more on that below).
So hackers call into the phone system, automatically try different passwords until they get through and then make calls to premium toll phone numbers (900) or other phone numbers to rack up charges.
Broadview decided years ago to cut this off by simply eliminating the not often used “call out” feature, thus thwarting the hackers.
We also recommend that OfficeSuite Phone customers update their “Permission profiles” by turning off any calling permissions that employees do not need or should not have, especially when the office is closed.
There was another problem years ago of overnight cleaning crews racking up international calls while working without much oversight. Companies were surprised to see lots of unusual international calls on their bill and were again worried about hackers.
With the OfficeSuite Phone service you can turn off any type of call, except emergency, during “closed” hours. Plus you can define “closed” hours differently for different people or groups with our Business Hours function. This is especially useful if you have multiple shifts during the day.
Finally, it is always recommended to change passwords at least once a year. We offer passwords up to 10 digits which are significantly harder for hackers to crack than four digits. We also recommend not using easy to remember passwords like 1111 or 1234.
