Refer to the Oxygen Forensic. Suite 2012 help file to learn what must be done in.During the 1980s, most digital forensic investigations consisted of 'live analysis', examining digital media directly using non-specialist tools. In the 1990s, several freeware and other proprietary tools (both hardware and software) were created to allow investigations to take place without modifying media.
Is one of the largest smartphone chipmakers in the world. All you need to do is to switch Tablet PC on, choose a cable from the cable set, run Oxygen Forensic® Extractor and connect a device.The Digital Forensics Market is Segmented by Component (Hardware, Software. July 2021 - Oxygen Forensics released flagship software, Oxygen Forensic.Not only extraction, but also immediate view and analysis of data. In comparison with other forensic hardware Oxygen Forensic® Kit allows not only to extract data from the device but also to create reports and analyze data right in the field.
How It WorksThe device must be put into BOOT ROM (BROM) mode before starting the reading. Oxygen Forensic Detective currently supports more than 100 modifications of MTK chipsets. The extraction method is based on a low-level proprietary protocol designed for firmware updates and recovery of MTK-based devices, which permits extraction from password-locked devices.
Oxygen Forensic Install The Driver
Some devices do not work with the standard driver and require a special driver from the manufacturer.In BROM mode, basic information about the hardware of the MTK device under investigation can be acquired. Otherwise, the user will have to reinstall the driver within the system or find the correct driver for this device and repeat the process. If the MTK driver is installed correctly, the extraction process will continue. If the response is not received from the PC within 1 second, the device turns off and switches back to USB charging mode.For optimal functionality in this mode, we recommend installing a driver to the system, which is included in the product.
If Secure Startup mode is disabled in the OS settings, the default password (default_password) is used by the system, which is the standard behavior of the Android OS.It is worth noting that in the cheaper MTK chips, a number of modules responsible for cryptography at the hardware level are not implemented. Encryption is performed using hardware support.If the memory of an MTK device is encrypted, the extracted physical dump content will be encrypted as well, and the user will have to enter or identify the password in order to decrypt the data. In MTK-based devices a security mechanism known as Full Disk Encryption is generally used. Full Disk EncryptionAndroid OS offers complete encryption of the device’s memory, and is enabled. To support devices that do not work with the standard DA file, a third-party DA file can be uploaded in Oxygen Forensic Detective. This operation does not change the device firmware and, therefore, is safe for its operation and data preservation.DA mode provides a higher-level device interacting API and offers commands for reading the physical dump of the device.
Oxygen Forensic Full Implementation Of
Currently, only the older MTK line of Helio chipsets starting with Helio X20 MT6797 have full implementation of hardware key storage. These devices use the old software-based encryption scheme and their password can be brute-forced offline using the Passware module in Oxygen Forensic Detective. At the same time, some Android ≥ 5.0 MTK devices do not have hardware key storage implemented. For example, the used hardware key prevents password identification based only on the information stored in the extracted physical dump.
Bruteforce or enter the password if Secure Startup mode is activated If the hardware-backed key encryption is used and the chipset is vulnerable – extract the hardware-backed key Connect the device in MTK mode – information regarding the chipset is available upon connection A special exploit that allows hardware encryption key extraction and follows data decryption is incorporated into our software.
Auth file using the above mentioned secret key Auth file in order to log in to BROM The device sends a request to get a special. The manufacturer puts a secret key into the device Auth file works as follows:
Consequently, it also prevents forensic software from accessing the data. Auth file are needed to log in to BROM.The purpose of this protection is to restrict the access of an ordinary user to the firmware service mode or recovery. Auth file is validThus, a signed DA file and/or valid.
To determine if BROM mode is blocked on a particular phone, open the device manager and connect the MTK device. As for models released before 2014, BROM protection is usually absent.Some manufacturers block BROM mode on their devices, making it impossible to read the device using this method. If the manufacturer has enabled BROM protection on the device, our software will not be able to extract data. Unfortunately, these 20% include the most popular devices from well-known and popular manufacturers, such as Meizu, Huawei, Asus, etc.
Connect the device to a PC with a USB cable. The software will search for the connected device.2. Select MTK Android Dump method in Oxygen Forensic Extractor and follow the displayed instructions. Instructions for MTK Android Dump1. Before verifying if BROM mode is blocked, make sure that the MTK driver is installed, otherwise the device will not appear in device manager in any case. If the device does not appear in the device manager, then this mode is blocked.
Connect the device to a PC using a USB cable, wait for the exploit to finish, and click Next.6. The software will search for the connected device, read the encryption keys, and initiate password check.5. Before starting the exploit, disconnect the device from the PC.4. If the device’s memory is encrypted using hardware-backed keys, a screen will appear describing the data decryption process. The physical dump extraction of the device’s memory will begin. Make sure the corresponding drivers are installed.3.
The data extraction from the Android physical image will then begin. The decryption key will be generated using the password and the acquired encryption keys.8. If no user password is available, brute forcing the password with the help of Passware Kit Mobile to decrypt data, will be required.7.
