VoIP facing new hacking threat

VoIP facing new hacking threat

Businesses across the UK may have already recognised the advantages that come with using voice over internet protocol (VoIP), but security still cannot be overlooked.

Phone hacking is perhaps something many people would associate with unscrupulous tabloid journalists, but it is businesses rather than celebrities that are most at risk.

Indeed a new study from security consultancy Nettitude, claims firms across the UK are being disproportionately affected, contending with a surge of attacks.

It claims the rising use of VoIP as a communications platform has coincided with a rise in tools that help to hack into systems around the world

As a result, the first quarter of 2015 has, according to research, seen a dramatic rise in breaches.

Nettitude researchers found that 88 per cent of attacks took place outside of regular working hours – a move used to ensure there is no one there to monitor the system.

One tool being used by hackers is SIPVicious, which is originally designed for use in auditing SIP systems, but experts claim it can also be used to determine the VoIP system being used by a targeted company and then run a password-cracking attack.

While service abuse and toll fraud have been the most common goals for hackers, the report has also found a sharp increase in premium rate service (PRS) fraud, adding there had also been a large number of failed password attempts on the systems it monitors.

The report said: "We recorded a large number of calls to premium numbers and foreign numbers. Such actions can have serious financial impacts on the organisation being attacked.

"The large number of failed attempts to log into the system, register and make calls affected the performance of the system. Such behaviour could cause denial of service, making the services unavailable for legitimate users."

It all means that security cannot afford to be overlooked when it comes to implementing VoIP within a corporate communications structure.
