Around fourteen WiFi VoIP handsets and phones have been tested by top security experts, who say that security problems range from potential DoS attacks to more serious problems that allow “deep access” to the device that lets a hacker read any sensitive information on the phone.
Problems like this inevitable. So who should sort it out? It has been suggested that if we see practices like this grow as these devices become more prevalent then the manufacturers will only have themselves to blame when the security backlash comes back to haunt them.
VoIP hacking is the modern days version of war dialing - a method of automatically scanning telephone numbers using a modem, frequently ringing all telephone number in a local area to find where computers or fax machines are available, then attempting to access them by guessing passwords.
Still there are precautions customers can take to protect themselves. Here’s a list of WiFi VOIP security issues, and some effective ways to protect against them:
Multiple points of attack:
As the phones get more advanced, so could the points of entry for would be hackers. Email, client Web browsers, Bluetooth, SMS, WiFi, media players, and image viewers could all provide a window of opportunity for hackers. Though users can use open-source and commercial tools to regularly test their phones and networks, they’ll ultimately have to rely on vendors to also do proactive testing on these devices.
Targeting phones in public environments:
For example a Bluetooth scanner could be concealed at the entrance to a major airport or train station and be used to grab user data. It may be best to keep Bluetooth and other wireless features swicthed off when not needed.
Rogue access points:
Other than this when at the office or on the road, users will have to always be wary and scan for rogue access points. Unscrupulous individuals will set up access points to target specifically WiFi phones in the corporate space as well as at hotels and other places business people like to come together. Decent device authentication and encryption can help provide protection here.
Targeted attacks:
Select attacks on specific voice-over-wireless networks could also be an issue, albeit one that the victims may prefer to keep quiet.

Normally it is considered polite to turn off your wireless devices during a public show, but a recent development will have you flipping them open out of pure respect. Verizon will soon be inquiring moviegoers regarding their musical preferences. Rather than merely viewing commercials during pre-movie procedure, viewers will be allowed to flip open their electronics and send in survey responses.
The promotion, which plans to begin in mid-June, will precede film showings in the US and possibly in the United Kingdom. Moviegoers will be asked questions about musical preferences, and will be allowed response by email and text. Following their response, moviegoers will view a series of adverts from Verizon, followed by a statistical display of the audience’s preferences.
These innovative advertisement viewings, made possible by Screenvision, allow mobile broadband users the ability to respond to local advertisements. The capability to do this is gained through relative digital distribution, making statistical advertisements possible without printing individual copies of material. This will replace many traditional Verizon slides in movies and email distribution. The deployments of these adverts are expected to work similar to Google Adwords, allowing advertisers to bid for ads per viewing and customer, linked to films of a specifically chosen genre.
