Darkmatter: a secure Paranoid Android version that hides from attackers

Stock Android phones with the Darkmatter OS use encrypted storage, OS-level app controls, and secure messaging by default, but if the phone thinks it's under attack, it dismounts all the encrypted stuff and reboots as a stock Android phone with no obvious hints that its owner has anything hidden on it.

Mobile malware infections race through Hong Kong's Umbrella Revolution


The protesters are dependent on mobile apps to coordinate their huge, seemingly unstoppable uprising, and someone -- maybe the Politburo, maybe a contractor -- has released virulent Ios and Android malware into their cohort, and the pathogens are blazing through their electronic ecosystem.

Samsung Galaxy back-door allows for over-the-air filesystem access


Developers from the Replicant project (a free Android offshoot) have documented a serious software back-door in Samsung's Android phones, which "provides remote access to the data stored on the device." They believe it is "likely" that the backdoor could provide "over-the-air remote control" to "access the phone's file system."

At issue is Samsung's proprietary IPC protocol, used in its modems. This protocol implements a set of commands called "RFS commands." The Replicant team says that it can't find "any particular legitimacy nor relevant use-case" for adding these commands, but adds that "it is possible that these were added for legitimate purposes, without the intent of doing harm by providing a back-door. Nevertheless, the result is the same and it allows the modem to access the phone's storage."

The Replicant site includes proof-of-concept sourcecode for a program that will access the file-system over the modem. Replicant has created a replacement for the relevant Samsung software that does not allow for back-door access.

Boeing's self-destructing, tamper-resistant spookphone: the Black


Boeing has sought regulatory approval from the FCC for a tamper-resistant phone intended to self-destruct if its case is opened. The phone, called "Black," runs Android, and is intended for use under the DoD Mobile Classified Capabilities guidelines. It will be sold with a nondisclosure agreement prohibiting tampering or service, and opening the case will trigger a system intended to wipe the phone's data.

Interestingly, it has a removable battery (something that's become increasingly scarce in smartphones). Best operational security practice holds that you should remove your phone's battery when you want to be sure that it's off, because any malware that turned your phone into a bug could also cause it to simulate being switched off while it remained running.

It's an intriguing technical problem. I'm intuitively skeptical of the security model. I can believe that this phone will be tamper-evident, but I don't know if it will be all that tamper-resistant. That is, it may be capable of preventing an attacker from surreptitiously opening the case to access the components, but how about an adversary willing to simply smash the screen to get at the components beneath?

The manufacturer could make a phone whose accelerometer tried to detect these events and wipe the device as a precaution, but I suspect there'd be a lot of spooks who'd end up cursing their self-destructing phones every time they butterfingered them while getting them out of a pocket while walking down the street. I'm pretty sure that I can use tools to remove my phone's screen in a way that generates less detectable stress than it receives during everyday knockabout and drops.

Woz: Apple should make Android phone

Mat Honan, at Wired, quotes co-founder Steve Wozniak: “The great products really come from secret development,” he said. “You put small teams of great people on them and they aren’t bothered by other people commenting on what they’re doing while they’re doing it. A whole new category of products doesn’t happen very often. It might happen once a decade. Sometimes you have to wait for one of those to come about.”

Teach your rooted Android phones to lie to apps about whether it's rooted

There's a funny paradox in rooting your Android phone. Once you take total control over your phone, some apps refuse to run, because they're trying to do something that treats you as untrusted. Now there's a utility called Rootcloak that lets you tell your rooted phone to lie to apps about whether it is rooted. It's both long overdue and a neat demonstration of what it means to be root on a computer. Cory 10

Blackphone: a privacy-oriented, high-end, unlocked phone

http://vimeo.com/84167384

Blackphone is a secure, privacy-oriented mobile phone company co-founded by PGP inventor Phil Zimmerman. It integrates a lot of the privacy functionality of Zimmerman's Silent Circle, which makes Android-based privacy tools (secure calls, messaging, storage and proxies). Blackphone also runs Android, with a skin that switches on all the security stuff by default. The company is based in Switzerland, whose government privacy rules are better than most. The phone itself is a high-end, unlocked GSM handset. No info on pricing yet, but pre-orders open in late February. I'm interested in whether the sourcecode for the Blackphone stack will be free, open, auditable and transparent. If it is, I will certainly order one of these for myself and report here on its performance.

HOWTO delete your smartphone's fine-grained log of everywhere you've been

If you have an Android or Ios smartphone, it defaults to storing the history of all the places you go, at a very fine resolution, for a very long time, and mirrors that data on remote servers from which it might be leaked or subpoenaed. Lifehacker has a great tutorial on deleting your Location History and turning off future logging of your location. They cover both Ios and Android. I just did my devices, and it was very easy.

Audio game app for blind people

Bob Smolenski says: "I've released a new audio game app for blind and visually impaired. Open Field Echo Sounder uses GPS on your iPhone or Android. Walk to the center of an open field and six virtual targets will be arranged around you. Echo locate them using headphones to determine direction. Sighted folks can play it also ;)"

Google yanks vital Android privacy feature

Well, that didn't take long: shortly after Google added a new Android feature that let you deny apps access to your sensitive personal data, they have revoked it. This is frankly terrible, and the Electronic Frontier Foundation's Peter Eckersley has some very pointed commentary, recommendations for Android customers, and advice for Google:

Android gives you the ability to deny your sensitive data to apps

Android privacy just got a lot better. The 4.3 version of Google's mobile operating system now has hooks that allow you to override the permissions requested by the apps you install. So if you download a flashlight app that wants to harvest your location and phone ID, you can install it, and then use an app like AppOps Launcher to tell Android to withhold the information.

Peter Ecklersley, a staff technologist at the Electronic Frontier Foundation, has written up a good explanation of how this works, and he attributes the decision to competitive pressure from Ios, which allows users to deny location data to apps, even if they "require" it during the installation process.

I think that's right, but not the whole story: Android has also always labored under competitive pressure from its free/open forks, like Cyanogenmod.

Cyanogenmod adds encrypted SMS from WhisperSystems

The latest (unstable) build of Cyanogenmod (a free/open version of Android) incorporates a secure, encrypted SMS program called TextSecure, which was created by Open WhisperSystems. Open WhisperSystems's chief engineer is the respected cryptographer and privacy advocate Moxie Marlinspike, and the source for the Cyanogenmod integration is open and available for inspection and scrutiny. The new encrypted SMS is designed to be integrated with whatever SMS app you use on your phone, and allows for extremely private, interception- and surveillance-resistant messaging over the normally insecure SMS. It requires that both parties be using TextSecure, of course -- if you send a TextSecure message to someone without secure messaging, the message will fall back to unencrypted text.

Cyanogenmod installer removed from Google Play store

Two weeks ago, the one-click Cyanogenmod installer hit the Google Play store, making it possible to switch from the stock Android operating system to a more free, more open version without any special expertise. Yesterday, Google asked Cyanogenmod to remove the installer, because using it voids your device's warranty. I've downloaded other apps from the Play Store that root your device and void the warranty, so this seems like a very selective enforcement to me.

In any event, Cyanogenmod's installer can be "sideloaded" into your device without having to go through the Play Store (one of the advantages of Android is that it doesn't attempt to prevent you from installing unapproved software). Hundreds of thousands of people used the Play Store version, and we can hope that it remains in use, even without Google's official support.

One-click Cyanogenmod installer in the Play store


Cyanogenmod Installer is a one-click Android app that unlocks your bootloader, roots your device, and flashes Cyanogenmod's OS onto it. Cyanogenmod is a free/open fork of Android, where much of the proprietary Google elements have been replaced by open equivalents, giving you lots more customizability and privacy in your device. For example, the Cyanogenmod device locating feature lets you find your phone, but makes it much harder for third parties to track you using the same feature. The company raised $7M in venture capital in September, and this is the first serious change the the OS since then, and it's a huge improvement. Previously, installing Cyanogenmod was pretty tricky and arcane, and was a huge barrier to adoption. Now you can download an app from the Play Store, and install with one click.
