Massive Security Vulnerability In HTC Android Devices (EVO 3D, 4G, Thunderbolt, Others) Exposes Phone Numbers, GPS, SMS, Emails Addresses, Much More

I am quite speechless right now. Justin Case and I have spent all day together with Trevor Eckhart (you may remember him as TrevE of DamageControl and Virus ROMs) looking into Trev's findings deep inside HTC's latest software installed on such phones as EVO 3D, EVO4G, Thunderbolt, and others.
These results are not pretty. In fact, they expose such ridiculously frivolous doings, which HTC has no one else to blame but itself, that the data-leaking Skype vulnerability Justin found earlier this year pales in comparison. Without further ado, let me break things down.
In recent updates to some of its devices, HTC introduces a suite of logging tools that collected information. Lots of information. LOTS. Whatever the reason was, whether for better understanding problems on users' devices, easier remote analysis, corporate evilness - it doesn't matter. If you, as a company, plant these information collectors on a device, you better be DAMN sure the information they collect is secured and only available to privileged services or the user, after opting in.
That is not the case. What Trevor found is only the tip of the iceberg - we are all still digging deeper - but currently any app on affected devices that requests a single android.permission.INTERNET (which is normal for any app that connects to the web or shows ads) can get its hands on:
