The Samsung Smartcam is a great example of why consumers should be wary of 'Internet of Things' devices. Multiple exploits for the camera have been found since the Smartcam initially went on sale, previously allowing for remote command execution and changing the admin password without knowing the original one. Now another exploit has been discovered for the Smartcam, this time allowing commands to be executed as the root user. Read More
Android developer extraordinaire Chainfire has worked his magic again, releasing a new beta of SuperSU with support for the Galaxy Note7. There are a few caveats though, mostly due to new Samsung security measures inherent in the kernel, stopping Chainfire from using his usual exploits and instead having to apply workarounds.
In short, Chainfire says that Samsung has applied new built-in protection methods directly to the kernel. Any time a 'privileged' process that has a uid/gid value equal to or below 1000, it causes the device to kernel panic, meaning it immediately reboots. As most root processes have a value below 1000, the device restarts as expected, causing headaches for both users and developers. Read More
Verizon has begun rolling out an update for the Galaxy Note Edge that should address the vulnerability in Stagefright, one of Android's media libraries, that could potentially compromise a user's device. This is the first Stagefright-related fix we're aware of Verizon rolling out.
Of course, the changelog doesn't specifically mention Stagefright... but it's really obvious that's what it's for, given the timing of the update and terseness of the document. You can probably expect a slew of Samsung Stagefright fixes (as well as other OEMs, of course) on Verizon to follow, if this is any sign. Read More
Ask anybody that spends time in the security circles and they'll tell you that every large software project is bound to have a few long-standing vulnerabilities in the code. Fortunately, there are usually a few people who are paid to close up those holes so you, the customer, don't find yourself the victim of nefarious evildoers someday. Like so many before it, the latest update to Android came with a boatload of changes, at least one of which fixes a potentially dangerous vulnerability that can be used for numerous attacks, including a way to acquire root.
As described in a post on the Cassidian CyberSecurity blog, the vulnerability exists in a system component known as VOLD (Volume Management daemon). Read More
If you're a root user, listen up. Chainfire updated SuperSU to v1.69 as of last night, which fixes two exploits that could allow an attacker to leverage root privileges without first prompting the user. Probably nothing to get overly anxious about, but it's definitely a good idea to make sure you're running the latest. Details of these exploits will be released next Monday, so you'll want to grab the update before then.
Fortunately, this one's pretty easy – just install the update from the Play Store and you're covered; no need to flash anything.
This update also includes a handful of other fixes and things:
- XBIN mode (some new roots need this)
- Slightly adjusted binary installer
- Backup script installation now available for all backuptool-capable ROMs
- Fixed su-ing to a non-root user not working on some 4.3+ firmwares
- Fixed BOOTCLASSPATH vulnerability (CVE-2013-6774) - Fixed notification sanitization vulnerability (CVE-2013-6775) - Fixed possible closed special files vulnerability
- Updated language files
The update is already live in the Play Store, so make sure to pull it down as soon as you can. Read More
The second annual Mobile Pwn2Own competition, run by HP TippingPoint's Zero Day Initiative, is fast approaching. This year's event will take place at the PacSec Applied Security Conference in Tokyo from November 13-14, and over $300,000 in cash and prizes is up for grabs. The Pwn2Own contest challenges security researchers to find and exploit vulnerabilities on mobile devices and rewards them by giving them the device they were able to compromise. In short, a contestant must "pwn" a device in order to own it. This year's event is sponsored by Google's Android Security Team and BlackBerry.
Contestants can receive $50,000 for compromising a mobile device using Bluetooth, Wi-Fi, USB, or NFC. Read More
Since Dan Rosenberg declared his intentions to stop publishing exploits for Motorola devices, fans of the OEM have been wondering if there will be much of a future within the modding community. While the distant future is still very foggy, Justin Case has come to the rescue with his own rooting method for Motorola's latest salvo of devices. His simple-to-use app roots the Moto X, Ultra, Mini, and Maxx.
I'm sure most of you are here to get your phone rooted, so let's go straight to the instructions. I will follow with a more in-depth explanation about how it works. Read More
When it comes right down to it, few things are much scarier than finding out somebody can track your movements, read your call log and text messages, and even record audio and take pictures of whatever the phone can get, all without your knowledge. Here's the thing - as careful, security-conscious people, many of us already install software like that for our own purposes, usually to recover a phone in the event it should fall into the hands of thieves. Like a weapon intended for protection, sometimes our best defenses can be turned against us.
It was recently discovered that Cerberus anti theft, a tool we've talked about a few times in the past, has a weakness in its network protocol that allows a determined hacker to use brute-force methods to find the IMEI numbers of user devices and ultimately invoke any of Cerberus's functions.

It was only yesterday that Cyanogen definitively confirmed AT&T's treacherous move to lock down the Galaxy S4's bootloader, but there is light at the end of that tunnel. No thanks to AT&T but to security researcher extraordinaire and a person I admire Dan Rosenberg, a.k.a. the magician, a.k.a. the root whisperer.
Dan, who is responsible for numerous root and unlock exploits, tweeted this photo of his Galaxy S4 earlier today:
There are no instructions or blog posts explaining the unlock at Dan's blog yet - these should be coming in the future. When, you might ask? This part is not decided just yet, for a good reason (put down your pitchforks). Read More
When it comes to root and mod action on Motorola devices from the last couple of years, all eyes turn to brilliant Android hacker Dan Rosenberg. Since the Droid 3 was released two years ago, Rosenberg has successfully found root exploits for every Motorola device, including the D3, Bionic, RAZR, Droid 4, Xoom 2, Atrix HD, RAZR HD, and RAZR M. Add to that the fact he just released a tool that unlocks the bootloaders on the most modern Moto phones (RAZR HD, M, and Atrix HD), and it's not hard to see why he's such an important part of the Motorola modding community.
