Hackers eye internet telephony
In the present age of computers, you probably can not find any secure and safe option. Every other thing is prone to hacking and tracking.
If you shop or make any sort of monetary transaction on the net, your card may be hacked by the hackers and thus misused later. Now the internet telephony has also become a target of malicious activity of the hackers.
In Australia, the internet protocol telephony networks are under the threat of such danger posed by the hackers. According to Scott Ferguson net phone attacks are rare but increasing day by day. Really someone has rightly said, in this age and time, ways of destruction come before ways of construction.
So just keep a watch!
