In light of the voice mail hacking story in the UK by newspapers Brian Krebs has a great article on his blog from this weekend about how easy it is to “hack” into ATT voicemail using a caller ID spoofing service like spooftel.com.
Even with a password set on your ATT voice mail someone can call your phone with a spoofing service and have full access to anything you have saved in the box.
So the moral of the story is to never save a voice mail that you wouldn’t want someone with access to the internet to hear.
