AT&T And T-Mobile Pay Up For Not Being Truthful About Voicemail Hackability

from the caller-id-spoofing dept

Many mobile phones' voicemail systems have worked on the basis of checking the caller ID of the incoming caller -- and if it matched the number of the voicemail box, it would automatically push the caller through to the admin interface. The idea was that if the owner of the box was calling, he or she shouldn't have to put in the passcode to get to the messages. The only problem with this was that, if anyone could spoof your caller ID, they could access your voicemail. After a few high profile such voicemail attacks, many mobile operators urged customers to change their voicemail preferences to require a passcode, no matter what. Still, there were some operations out there, that went under names like SpoofCard, Love Detect and Liar Card, that would spoof a caller ID to get access to a voicemail box. The company behind them has been fined, but what may be more interesting is that T-Mobile and AT&T were also both fined for apparently being misleading about their susceptibility to the hack.

That seems a bit strange, and the article is woefully short on details, unfortunately. Pretty much anything is hackable given certain circumstances, and it always seems a bit odd to totally blame a hacking victim for being hacked. So it would be good to know why T-Mobile and AT&T, in particular, were fined in this case. Did they not even allow passcodes to be enabled for those who wanted to avoid this potential hack?
