Last week, we wrote about the security glitch
by AT&T, that allowed hackers to figure out the email addresses of 114,000 iPad users. A few people in the comments mocked this news, claiming that such info was pretty much meaningless, as email addresses are hardly private info these days. Of course, that ignored the connection of the email address to the fact that you bought an iPad. But now, some are realizing the potential security problems with this may be significantly worse. Slashdot
point us to a story where someone walks through how poor security choices by the various mobile operators means that knowing the information revealed by the glitch can actually reveal much, much more
. As the blog post walks through the details, it concludes that potentially
, the data from the breach in some cases (though, not all) could then be used to figure out a lot more:
So yeah, knowing someone's ICCID can give you their full unpublished billing name, their cellular phone number (and hence their home address), their current location on a realtime basis, their voicemail, and if you're prepared to follow them around (within a few miles) then you get all their phone calls and SMS messages too.
There is a later edit, when he realizes that the voicemail/phone calls/SMS stuff might not be that big of a deal, since the iPad is not a phone device, but it's still instructive of how a "simple" data breach can lead to much more in certain circumstances.
