Kaspersky details super-advanced 'Skygofree' Android trojan

Ryan Whitwam

Security firms spot new malware variations all the time, but most of them aren't very sophisticated. They don't have to be to spam ads or track your location. However, the newly identified Skygofree is in a completely different league. According to Kaspersky, this piece of malware possesses features never before seen in the wild.

Chainfire Explains His Root Method For The Latest Lollipop Developer Preview, Modified Kernels May Become A Requirement

Cody Toombs

The final round of Developer Preview images released on Friday left a number of users without root access on their devices, but a lightning fast quick-fix by Chainfire had them back in business the following day. Yesterday, he took to Google+ with a follow-up of how it works and the issues that are making it more difficult to acquire root on the latest version of Android.

Due to increasingly effective security measures and stricter enforcement of SELinux, it seems that many, or possibly all of the available methods for initializing the SuperSU daemon at startup have been rendered ineffective. As part of Chainfire's updated root, custom kernels were posted for the Nexus 5, Nexus 7, and ADT-1 that switch a few SELinux policies to permissive mode so that SuperSU can be run in the correct context after a device boots up.

[New App] Bluebox Heartbleed Scanner Can Help You Discover An OpenSSL Vulnerability On Your Device

Cody Toombs

The Internet has been abuzz over the recently discovered Heartbleed bug. If you're not already familiar, Heartbleed is a vulnerability in the OpenSSL software library that allows an attacker to steal data directly from the memory space of an application and learn the private keys used to keep data securely encrypted as it travels over the Internet. The implications of this kind of leak are certainly severe, and it has everybody rushing to either install updates that fix the bug or implement workarounds to disable it.

As users, there's not a lot you can do to close this security hole on your device, but you might still want to know if you're vulnerable.

New Firewater S-Off Tool Will Unlock Any HTC Device In Moments

Ryan Whitwam

Like most OEMs, HTC likes to lock down the devices it sells to the general public, but maybe you like a little more freedom. That means an exploit is required to get s-off status. The new Firewater S-Off tool can manage that for any (or at least very nearly any) HTC device, even newer HTC One phones.

The tool comes courtesy of developers beaups and fuses, and it's completely free for personal use. Just download the files and get to work. The website has a full walkthrough of the process. There are some prerequisites that need to be taken care of first, though.

RockMyMoto Roots Moto X After Latest Camera Update, Should Work On All Recent Motorola Phones

Cody Toombs

Some Moto X owners weren't particularly happy to learn that a recent OTA with improvements to the camera also had the undesirable consequence of breaking root acquired through PwnMyMoto. Fortunately, the creator of PwnMyMoto, Justin Case, is back with an updated root method that works on the latest Moto X update and should be compatible with all recent Motorola firmwares.

Update: RockMyMoto is confirmed to also work on the latest firmwares for the Droid Maxx, Ultra, and Mini.

[Security] Vulnerability In Firefox For Android Discovered That Allows Hackers To Steal Files From The SD Card And Firefox's Privately Stored Data [Update]

Cody Toombs

The security of our mobile apps and private data is a very serious matter. This is particularly true for high value targets like web browsers, which often store login credentials that can be used to access many of the websites we use on a regular basis. Unfortunately, browsers are also very complicated applications with an extensive set of features that are difficult to lock down completely. Sebastián Guerrero Selma of viaForensics recently posted a video demonstrating a newly discovered vulnerability in Firefox for Android which would allow hackers to access both the contents of the SD card and the browser's private data.

PwnMyMoto Roots And Bypasses Write Protection On Moto X, Droid Ultra, Mini, And Maxx, Makes Flashing Custom ROMs A Reality

Cody Toombs

That didn't take long. Just 2 days after Justin Case released a root method for the Moto X, Droid Ultra, Droid Mini, and Droid Maxx, he's already back with a hack that bypasses write protection. By disabling the write protection afforded by the bootloader, it becomes possible to flash 3rd-party ROMs, themes, and other mods. In other words, the flood gates are open for the modding community.

Much like MotoRoot, PwnMyMoto is packaged as a single app that must be sideloaded with adb. After running it and waiting through 2-3 reboots, your phone will be set up to boot into either the standard write-protected mode (recommended for daily use) or with write protection disabled.

[Security] Firefox For Android Can Be Tricked Into Automatically Downloading And Executing Malicious Code

Cody Toombs

A very serious security hole has been discovered in Firefox for Android that allows a website to force the browser to download and run potentially damaging files, usually without the user's knowledge or interaction. The vulnerability was first described and demonstrated publicly on September 9th as part of a posting meant to advertise the attack as being for sale. The method for exploiting the weakness simply requires a webserver to instruct Firefox for Android to initiate a download, after which the downloaded file is automatically opened or executed (depending on the file type).

Here's a demonstration using an apk crafted to look like an update to Firefox:

While the demo video above uses an apk and relies on a user being tricked into installing it, the potential vectors of attack aren't restricted simply to apks and can possibly leverage other weaknesses on a device.

Second "Master Key" Style APK Exploit Is Revealed Just Two Days After Original Goes Public, Already Patched By Google

Cody Toombs

Hot on the heels of Bluebox's disclosure of the "Master Key" exploit, a Chinese blog has posted details of a similar vulnerability. This attack also sidesteps a bug in the signature verification step and allows seemingly innocent APKs to include a potentially dangerous payload; and like its brethren, Google has already patched the flaw and posted it to the Android Open Source Project (AOSP). The information comes to us from a China-based group (or possibly individual) calling itself the Android Security Squad. The original post is in Chinese, but a vaguely comprehensible translation can be had thanks to Google.
