Remote police WiFi network investigation and evidence collection system based on raspberry pi and method thereof

Abstract

The invention discloses a remote police WiFi network investigation and evidence collection system based on the raspberry pi and a method thereof. The system comprises a remote evidence collection terminal, the remote evidence collection terminal comprises a raspberry pi controller, and a plurality of WiFi crack schemes are stored in the raspberry pi controller; the raspberry pi controller is connected with a first WiFi wireless network card; the WiFi wireless network card is used for calling a WiFi crack scheme matched with a suspect WiFi network in the raspberry pi controller to crack the suspect WiFi network, monitor a data packet in the WiFi network and form evidence collection data, and transmitting the evidence collection data to the raspberry pi controller for storage, when a monitoring mode is opened; and the raspberry pi controller is further connected with an environment detection module, the environment detection module is used for detecting surrounding environment information of the evidence collection system and transmitting the surrounding environment information to the raspberry pi controller, and when the environment information received by the raspberry pi controller is not within a preset environment information safety threshold range, the raspberry pi controller deletes the evidence collection data.

Description

technical field [0001] The invention belongs to the field of remote control, and in particular relates to a police remote WiFi network investigation and evidence collection system based on a raspberry pie and a method thereof. Background technique [0002] With the rapid development of WiFi technology and the widespread use of mobile devices, mobile social networks are developing rapidly. The ways of cyber crimes such as cyber attacks and telecommunications fraud are not limited to using wired networks, but are carried out through wireless networks. It is of great significance for the investigation and handling of many cases to realize the monitoring and obtain the internal data packets of the suspect's WiFi network. However, the coverage of WiFi signals is small and the degree of encryption is high, so it is very difficult to obtain evidence of criminal records. [0003] Network forensics is a hot spot in the research of forensics technology in recent years. However, netw...
