OnePlus One users might be waiting for the new Lollipop based ROM for their smartphones. The wait is over as the popular Chinese smartphone maker OnePlus has finally released its own custom ROM --  OnePlus OxygenOS , which is based on Android 5.0 Lollipop. Last month, the OnePlus announced the official release of its in-house OxygenOS to 'One' on or before March 27, but was failed to deliver the update due to a couple of security issues discovered in the update.

Billions of Android Devices Vulnerable to Privilege Escalation Except Android 5.0 Lollipop

November 20, 2014Wang Wei
A security weakness in Android mobile operating system versions below 5.0 that puts potentially every Android device at risk for privilege escalation attacks, has been patched in  Android 5.0 Lollipop  – the latest version of the mobile operating system. The security vulnerability ( CVE-2014-7911 ), discovered by a security researcher named Jann Horn , could allow any potential attacker to bypass the Address Space Layout Randomization (ASLR) defense and execute arbitrary code of their choice on a target device under certain circumstances. ASLR is a technique involved in protection from buffer overflow attacks. The flaw resides in java.io.ObjectInputStream , which fails to check whether an Object that is being deserialized is actually a serializable object. The vulnerability was reported by the researcher to Google security team earlier this year. According to the security researcher, android apps can communicate with system_service, which runs under admin privileges

Google's Android Mobile operating system for smartphones and tablets have Google's own Play Store that provides its Android users the most visible way to access the world of millions of apps. App developers produce more than thousands of applications each year, but majority of newbie and unprofessional developers use unsafe, unreliable, and insecure coding practices, as many developers store secret keys in their apps that could potentially allow cybercriminals to steal users' sensitive data. A team of researchers from the computer science department of the Columbia University have discovered a critical security problem in the Google's official Android app store from where millions of Android users download various apps. Researchers have found that most of the Android application developers often store their secret keys in their app's code, similar to usernames/passwords information, which could be then used by any bad actor to maliciously steal users' information or r

In a previous story, I reported about a new ransomware threat known as Simplocker discovered by researchers at the security firm ESET, targeting Android users in the UK, Switzerland, Germany, India and Russia, for ransom. Simplocker (Android/Simplocker.A) is the latest Android ransomware that has ability to encrypt the files using Advanced Encryption Standard (AES) on the Android device SD cards demanding users pay a ransom of 260 UAH ( Ukrainian hryvnias ), which is roughly equal to $21 US, for those files to be decrypted. To hide their track, the malware author is using the Command-and-Control server hosted on TOR .onion domain, which makes it difficult to trace the server's physical location or determine who is operating it. The malware collects information about the users' phone such as IMEI number, Operating System, phone model and manufacturer to send it all to Command-and-Control server.

Google just made a huge change to the way application permissions work on Android devices which has left a potential door open to malicious app developers and hackers. Google narrows down Android's 145 permissions into 13 broad categories and groups app permissions into ' groups of related permissions ', likely for Android users to have an easier time dealing with app permissions. Unfortunately, the new update has introduced a few potential security and privacy issues, as listed below: hiding permissions behind the group names auto-updating app with no warning for new permissions According to new update, once a user approves an app's permissions, he actually approves the whole respective permission groups. For example, if an app want to read your incoming SMS messages, then it requires the " Read SMS messages " permission. But now installing an app, you are actually giving it access to all SMS-related permissions. The app developer can then include

First Android Ransomware that Encrypts SD Card Files

June 05, 2014Swati Khandelwal
We have seen cybercriminals targeting PCs with Ransomware malware that encrypts your files or lock down your computer and ask for a ransom amount to be paid in a specified duration of time to unlock it. To deliver the Ransomware malwares to the mobile devices, cyber criminals have already started creating malicious software programs for android devices. Last month, we reported about a new Police Ransomware malware that locks up the devices until the victims pay a ransom to get the keys to unlock the phone. But, the malware just lock the mobile screen and a loophole in the its implementation allowed users to recover their device and data stored on SDcard. Now, in an effort to overcome this, threat actors have adopted encryption in the development of mobile Ransomware malwares. Recently, the security firm ESET has discovered a new Android ransomware, dubbed as Android/Simplocker.A , that has ability to encrypt the files on the device SD card and then demand a ransom from the victim
