Hack a Day
The CAN bus is a rich vein to mine for a hacker: allowing the electronic elements of most current vehicles to be re-purposed and controlled with ease. [MikrocontrollerProjekte] has reverse engineered a CAN bus media and navigation controller and connected it to an STM32F746G-Discovery board. The STM32 is in turn connected to an Android phone, and allows the media controller to trigger a large number of functions on the phone, including music playback, maps, and general Android navigation.
When reverse engineering the controller, [MikrocontrollerProjekte] employed a variety of approaches. A small amount of information was found online, some fuzzing was …read more

In the United States, TV and radio stations have to give the opportunity of equal airtime to all candidates. In that spirit, we thought we should show you [Jayden17’s] hack that puts Google Assistant into a Teddy Ruxpin. You can see the hacked bear do its thing in the video below.
Teddy was the best-selling toy for 1985 and 1986, and is still available, so over 30 years there are a lot of these hanging around. If you never looked at how they work, the original ones were quite simple. A cassette player routed one stereo channel to a speaker …read more

Hack a Day
We’ve all been there: after assessing a problem and thinking about a solution, we immediately rush to pursue the first that comes to mind, only to later find that there was a vastly simpler alternative. Thankfully, developing an obscure solution, though sometimes frustrating at the time, does tend to make a good Hackaday post. This time it was [David Wehr] and AudioSerial: a simple way of outputting raw serial data over the audio port of an Android phone. Though [David] could have easily used USB OTG for this project, many microcontrollers don’t have the USB-to-TTL capabilities of his Arduino – …read more

While we here at Hackaday never question why an individual took on a particular project, it surely doesn’t stop our beloved readers from grabbing their pitchforks and demanding such answers in the comments. Perhaps no posts generate more of this sort of furore than the ones which feature old audio gear infused with modern hardware. In almost every case the answer is the same: the person liked the look and feel of vintage hardware, but didn’t want to be limited to antiquated media.
That sentiment is perhaps perfectly personified by the TapeLess Deck Project, created by [Artur Młynarz]. His creations …read more

We love to hack IKEA products, marvel at Raspberry Pi creations, and bask in the glow of video projection. [Nord Projects] combined these favorite things of ours into Lantern, a name as minimalist as the IKEA lamp it uses. But the result is nearly magic.
The key component in this build is a compact laser-illuminated video projector whose image is always in focus. Lantern’s primary user interface is moving the lamp around to switch between different channels of information projected on different surfaces. It would be a hassle if the user had to refocus after every move, but the focus-free …read more

Hack a Day
Have an ESP8266 development board such as the NodeMCU or Wemos D1? You’re currently reading Hackaday, so probably. Got an Android device kicking around? Also seems fairly likely. In that case, you should check out ESP8266 Loader by [Bluino Electronics]. This recently released application lets you not only flash new binaries to any ESP8266 board using the FTDI, PL2303, CH34X and CP210X USB chipsets, but also offers a serial monitor for debugging on the go.
You’ll need a USB OTG cable to get your ESP board jacked in to your Android device, but you don’t need root or even to …read more

Hack a Day
I recently spent a largely sleepless night at a hotel, and out of equal parts curiosity and boredom, decided to kill some time scanning the guest network to see what my fellow travelers might be up to. As you’d probably expect, I saw a veritable sea of Samsung and Apple devices. But buried among the seemingly endless number of smartphones charging next to their sleeping owners, I found something rather interesting. I was as picking up a number of Amazon-made devices, all of which had port 5555 open.
As a habitual Android tinkerer, this struck me as very odd. Port …read more

When project inspiration strikes, we’d love to do some quick tests immediately to investigate feasibility. Sadly we’re usually far from our workbench and its collection of sensor modules. This is especially frustrating when the desired sensor is in the smartphone we’re holding, standing near whatever triggered the inspiration. We could download a compass app, or a bubble level app, or something similar to glimpse sensor activity. But if we’re going to download an app, consider Google’s Science Journal app.
It was designed to be an educational resource, turning a smartphone’s sensor array into a pocket laboratory instrument and notebook for …read more

[Lambgx02] got tired of his Android device getting bogged down and decided to dig down to the cause of the issue. His investigation led him to believe that entropy is causing the slowdown. He believes that his workaround reduces 90% of the lag on the average Android device. So how is it possible that entropy [...]

This screen is not just cracked, it’s devastated. We can all agree that you’re not going to be carrying this around with you anymore, but it might still be useful in other endeavors.

[Adam Outler] and friends have been hard at work unlocking the bootloader of some Verizon Android devices. His most recent adventure involves unlocking the Verizon branded Samsung Galaxy Note II. You can’t run Cyanogenmod on a device that has a locked bootloader. This is presumably why it took no time at all for the XDA [...]

UPDATE - An easier way to do this can be found on our update post hereAndroid periodically updates it's SDK and
somtimes when this happens, old methods for importing a Trusted CA, necessary to proxy SSL traffic, will fail and you must find a new solution. Technically speaking, it's not necessarily the import that is the problem, it's saving those changes between restarts of the emulator. If you've worked with the emulator you'll note that after importing a Trusted CA such as BurpSuite's certificate, the changes only take effect once you've rebooted the emulator. In other words, you actually
have to restart the emulator, and without these steps, you'll lose your updated Trusted CA list.
Using Android SDK 19, the solution was to move a temporary file and rename it. Let's begin:
After creating your Android Virtual Device (AVD) named "test"....
Step 1 - Run the emulator
Step 2 - While running, pull the cacerts.bks file
Step 3 - Get the keytool
Step 4 - Import the PortSwigger SSL Certificate into the cacerts.bks file w/ keytoolNOTE: Exporting PortSwigger SSL Certificate instructions here - http://carnal0wnage.attackresearch.com/2010/11/iphone-burp.html
Step 5 - Remount the emulator /system folder with read-write permissions
Step 6 - Push the cacerts.bks file up onto the emulator
Step 7 - Move the tmp file to your local avd directory and rename it to system.img
Step 8 - Restart, rm cacerts.bks, pull down the copy from emulator, ensure certificate still exists in cacerts.bks file
The reason this data persisted was because we moved the temporary copy (emultor-<random string>) from /tmp/android-<myname>/ and renamed it to system.img. Lastly, we placed the image file in the ~/.android/avd/test.avd/ directory.

Android rootkit Event:
Black Hat Abu Dhabi 2011 Abstract: Android devices have been repeatedly hacked for root privileges. Sometimes by malware authors, and sometimes by users themselves. This is because if someone gains root privileges, he or she can gain control of the parts of the system which are most useful for attackers (and for users as well). But this is not the end of the story - we need a bit more knowledge to gain much privilege inside the Android application system. On the other hand, some Japanese Android smartphones have an extra Linux Security Module (LSM) to prevent these rooting issues and protect the system from being overwritten. But because of Android's security weaknesses and incomplete LSM protection, the Android application system can still be taken over by exploitation. This presentation explains what we can/cannot do if we gain root privileges on an Android device, and introduces a new kind of Android rootkit. This rootkit needs only root privileges (no kernel-mode, no ptrace) and bypasses all existing security modules. This fact implies the possibility of advanced Android malware.

Packet Storm Security Advisories
There is an issue in certain HTC builds of Android that can expose the user's 802.1X Wi-Fi credentials to any program with basic WI-FI permissions. When this is paired with the Internet access permissions, which most applications have, an application could easily send all stored Wi-Fi network credentials (user names, passwords, and SSID information) to a remote server. This exploit exposes enterprise-privileged credentials in a manner that allows targeted exploitation.

First impression is very good. The industrial design on this makes the iPhone look clunky. The screen is much bigger, the overall feel reeks of quality, just like the iPhone. The haptic feedback felt slightly odd at first, but I think I will like it when I get used to it.
I was disappointed when the phone failed to detect my 5GHz Wi-Fi network. This is like the iPhone, but the Samsung Galaxy S2 and Galaxy Nexus support 5 Ghz, and I had assumed parity for the Razr.
Oddly, bearing in mind its dual core processor, the Droid Razr sometimes seems sluggish compared to the iPhone 4. But the Android user interface is polished and usable, and it has a significant user interface feature that the iPhone sorely lacks: a universal ‘back’ button. The ‘back’ button, like the ‘undo’ feature in productivity apps, fits with the way people work and learn: try something, and if that doesn’t work, try something else.
The Razr camera is currently unusable for me. The first photo I took had a 4 second shutter lag. On investigation, I found that if you hold the phone still, pointed at a static scene, it takes a couple of seconds to auto-focus. If you wait patiently for this to happen, watching the screen and waiting for the focus to sharpen, then press the shutter button, there is almost no shutter lag. But if you try to ‘point and shoot’ the shutter lag can be agonizingly long – certainly long enough for a kid to dodge out of the frame. This may be fixable in software, and if so, I hope Motorola gets the fix out fast.
While playing with the phone, I found it got warm. Not uncomfortably hot, but warm enough to worry about the battery draining too fast. Investigating this, I found a wonderful power analysis display, showing which parts of the phone are consuming the most power. The display, not surprisingly, was consuming the most – 35%. But the second most, 24%, was being used by ‘Android OS’ and ‘Android System.’ As the battery expired, the phone kindly suggested that it could automatically shut things off for me when the power got low, like social network updates and GPS. It told me that this could double my battery life. Even so, battery life does not seem to be a strength of the Droid Razr. Over a few days, I observed that even when the phone was completely unused, the battery got down to 20% in 14 hours, and the vast majority of the power was spent on ‘Android OS.’
So nice as the Droid Razr is, on balance I still prefer the iPhone.
P.S. I had a nightmare activation experience – I bought the phone at Best Buy and supposedly due to a failure to communicate between the servers at Best Buy and Verizon, the phone didn’t activate on the Verizon network. After 8 hours of non-activation including an hour on the phone with Verizon customer support (30 minutes of which was the two of us waiting for Best Buy to answer their phone), I went to a local Verizon store which speedily activated the phone with a new SIM.
Deciding on the contract, I was re-stunned to rediscover that Verizon charges $20 per month for SMS. I gave this a miss since I can just use Google Voice, which costs $480 less over the life of the contract.
