Microdevice for secretly extracting information of Android mobile phone and extraction method

Abstract

The present invention discloses a microdevice for secretly extracting information of an Android mobile phone and an extraction method. The method comprises: firstly, connecting a microdevice with data of an Android mobile phone from which electronic evidence is to be extracted; secondly, communicating with an externally connected target Android mobile phone by using a pulling file interface provided by an adb debugging tool and an interface of establishing Socket communication; and then, acquiring a root access privilege out of the target mobile phone by using an adb root interface provided by the abd debugging tool: if the root access privilege can be acquired, directly and rapidly extracting a corresponding file according to settings of a user, and if the root access privilege can not be acquired, installing a plug-in that can communicate with the microdevice in the target mobile phone, and completing data extraction by using the plug-in. According to the solution provided by the present invention, the microdevice is very small in volume, convenient to hide and not easy to notice; without the need for operation of the user, automatic extraction is performed after a target device is connected to the microdevice; and an extraction speed is high, extraction of key data can be completed within a few seconds or tens of seconds and time of contact with the target device is short.

Description

technical field [0001] The invention relates to the technology of digital evidence collection or electronic evidence collection in judicial evidence collection, especially the technology of mobile device information extraction and electronic intelligence secret extraction. Background technique [0002] At present, the extraction of Android mobile phone information needs to be processed when the suspect has been detained or the suspect's mobile phone has been obtained. There is a big limitation like this, if the suspect who is still in the investigation phase or inconvenient to alert the suspect, it is difficult to get the suspect's mobile phone or can not operate the suspect's mobile phone for a long time. In this case, judicial forensics personnel often obtain the desired information through other indirect means, sometimes the complexity and time period are very long, and they cannot grasp the important clues to solve the case in a timely and effective manner. [0003] If ...
