Abstract
Purpose of the study: development of a method that allows detecting and identifying packets of the Tor network, including obfuscated packets on the local machine of the network user, by a Wireshark sniffer using the filter syntax based on the features of the Tor network packets characteristic of the TLS v1.2 and v1.3 encryption versions; studying the possibility of using the SSL Bump attack (decrypting https traffic on a virtual server using self-signed x.509 certificates) to overcome the obfuscation of Tor network packets. Method: software analysis of transmitted network packets, decomposition of the contents of data packets according to their size and belonging to encryption protocols, a comparative method in relation to different versions of the encryption protocol and resources, synthesis of filtering rules based on the syntax of the analyzer was used. Results: an applied method was developed that allows detecting and identifying packets of the Tor Network, including obfuscated packets on the local machine of the network user, by a Wireshark sniffer based on the filtering syntax based on the signs of encryption packets of the TLS v1.2 and v1.3 versions; data on the impossibility of using the SSL Bump attack to overcome the obfuscation of the Tor network was obtained.
