With the Arrival of Android 11, Google Changes the Way Of With the arrival of Android 11, Google changes the way of accessing the external area of data known as "external storage", with the new runtime these changes were implemented that everyone must follow. These privacy changes can be found at this link: https://developer.android.com/about/versions/11/privacy/storage which will provide a better explanation about these changes. For this, Google to allow the applications/games that used the outside area to save data the possibility of moving the important data to the allowed data area or to the new data structure that emulates the different external folders created the mode of "RequestLegacyMode" and for this, the developer must use API 29 in Build and Target in addition to checking "Legacy request Permissions" which is located inside the properties of Android, so the version that is built will have this permission and with the permissions of EXTERNAL_READ and EXTERNAL_WRITE will allow to continue reading and writing in the external area. It is important to remember that this mode only works on Android 10 and is automatically disabled on Android 11 devices, this mode should only be used for a short time in case it is necessary and then follows the policy of Google and Android that indicates that new applications must be built with API 30 and target 30. To save data to the internal area with the new folder structure a new expression inside the Android object called "Public Scoped Storage Directory" will allow to pull the specific folder that corresponds to the application/game. Developers are encouraged to read more about the policies implemented by Android latest date May/Aug 2021, more information here: https://developer.android.com/distribute/play-policies Additionally, in this new version, new permissions were incorporated, one to gain full access to External Storage and another to read the EXIF data embedded in the photos, within them the orientation of the photo necessary for the Android Camera Active Picture objects. in order to display the images in the correct orientation. 1.- MANAGE_EXTENAL_STORAGE, certain applications need to access all the content of the external area for them this permission was created by Google and is available from API 30 android 11+ for this the developer must comply with the regulations dictated by Google regarding get full access, more information: https://support.google.com/googleplay/android-developer/answer/10467955 This function is available at runtime through the Android object, the developer has a new action to request storage permission through action and a simple condition to verify if it was granted, the most important thing about this permission is It is only established once and by the user's hand when he turns it on in the settings. Here you may find the above example https://drive.google.com/file/d/1KCR7DdnzdTOZWkVppcyDmyN8Rry-zm1K/view?usp=sharing 2.- ACCESS_MEDIA_LOCATION, as mentioned in previous lines, this permission guarantees that the EXIF data within a photograph (location, orientation, and camera data) can be accessed, in the case of Fusion the necessary data is the orientation of the image to be able to display the image correctly. Remember that this permission is used for 11+ devices. What does the new application must ideally comply with? With the new concept for privacy implemented by Google Android, developers must conceptualize their data to reside in data internal (DataStorage) or using the Public Scoped Directories available from Android 11. For this developer doesn’t need to set any permission for any Android version. For Old developments, that only use data storage the same concept applies, no permission is needed and no modification. On the contrary, developers that save data in the external area still can do it but these files must be images, text, and HTML, other extensions like .arr or .ini are not recognized by the OS. There are users where their application saves images using a camera or by making a screenshot this is functional and was tested (see example below). In Android Object, users can now check if a permission is granted denied or blocked to react in their code according to this. Here you may find an example for this https://drive.google.com/file/d/1k4zUZhAy4C70EPpcFH1kzxM-69u10PS4/view?usp=sharing Android 11+: Storage scoped application: Access to external storage directories is limited to a specific application directory and specific types of media that the application has created. Automatic Permission Reset: If users haven't interacted with an app for a few months, the system automatically resets the app's confidential permissions. .

  • PIP Vulnerability in Android 11
    PIP Vulnerability in Android 11 TANMAY TYAGI AKSHAY SHARMA ABHINAV 1 Table of Contents ● Introduction ● Key Terms ● Definitions ○ PIP ( Picture-in-Picture ) ○ Android Manifest File ○ Local Privilege Escalation ● Affected Android Versions ● Unaffected Versions ● CVSS Score : CVE-2021 -0485 ● Virtual Environment ● Exploitation ● Mitigation ● References 2 PIP Vulnerability in Android 11 Introduction From 2017, Android imposed certain background execution limitations so that the applications in the background won’t be able to access the camera, microphone and other sensors. This reduced - ❏ notification pop-ups ❏ Advertisements (As apps can’t use microphones to listen for user interests) and improved - ❏ Battery ❏ Performance ❏ Security In PiP mode, there is no special permission required to control the minimum allowed window size so it is possible to create an arbitrary small window which won’t be visible to the user. Using this window, it is possible for an unprivileged application to maintain its foreground stage and bypass security restrictions which were introduced in Android Oreo and later for better performance, health and security. NIST DEF - In getMinimalSize of PipBoundsAlgorithm.java, there is a possible bypass of restrictions on background processes due to a permissions bypass. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. In this paper we will exploit this vulnerability in a virtual lab environment with a Proof of Concept. Confidential Document © Copyright of Safe Security 2021 3 PIP Vulnerability in Android 11 Key terms PIP ( Picture-in-Picture), Android Manifest File, Local Privilege Escalation Definitions PIP ( Picture-in-Picture) It is a Multi Window solution, generally used for video playback and extensively used in Gmaps.

  • The Android Platform Security Model∗
    The Android Platform Security Model∗ RENÉ MAYRHOFER, Google and Johannes Kepler University Linz JEFFREY VANDER STOEP, Google CHAD BRUBAKER, Google NICK KRALEVICH, Google Android is the most widely deployed end-user focused operating system. With its growing set of use cases encompassing communication, navigation, media consumption, entertainment, finance, health, and access to sensors, actuators, cameras, or microphones, its underlying security model needs to address a host of practical threats in a wide variety of scenarios while being useful to non-security experts. The model needs to strike a difficult balance between security, privacy, and usability for end users, assurances for app developers, and system performance under tight hardware constraints. While many of the underlying design principles have implicitly informed the overall system architecture, access control mechanisms, and mitigation techniques, the Android security model has previously not been formally published. This paper aims to both document the abstract model and discuss its implications. Based on a definition of the threat model and Android ecosystem context in which it operates, we analyze how the different security measures in past and current Android implementations work together to mitigate these threats. There are some special cases in applying the security model, and we discuss such deliberate deviations from the abstract model. CCS Concepts: • Security and privacy → Software and application security; Domain-specific security and privacy architectures; Operating systems security; • Human-centered computing → Ubiquitous and mobile devices. Additional Key Words and Phrases: Android, security, operating system, informal model 1 INTRODUCTION Android is, at the time of this writing, the most widely deployed end-user operating system.
