Hacking threatens VOIP

No business owner wants to come back to work in the morning, only to realise that their VoIP lines have been illegally used the entire weekend to call a number in East Timor at a rate of R7.50 per minute. Then, adding insult to injury, they later discover the fraudster made full use of their SIP trunk, which means 50 simultaneous calls for as long as possible. The potential result… a bill of R25 000 in a few hours.

Who is responsible for the breach? The end-users, for not securing their server or SIP account details? The provider, for not ensuring that preventive measures are put in place on its SIP infrastructure?

The more constructive questions would be: How and why? The how – the primary method that hackers use to gain access to your SIP account (your VoIP telephone) line is by simply cracking your password. More often than not it is found that end-users don’t take the time to change default passwords, leaving the door wide open for prowling hackers. The why – once your account has been breached, the hacker then proceeds to make calls to specific destinations where they get a share of the cost of the call. This can be extremely costly if you do not have credit limits on your account.

David Ridereau, Technical director of Wanatel and former security expert from IBM, has adopted the following philosophy: “If we cannot control our clients’ security system on their side, we need to be able to limit or even prevent the risks from our side.”

h highly secure and complex firewalls, limiting access to the network and implementing strict credit limits, what more could Wanatel do to prevent your account from being compromised? The answer… SIP Brigade.
