Abstract

U ovom radu pokazat ćemo kako smo izradili specifične alate za reverzanje ADONIS
operacijskog sustava i kako smo ih primijenili na reverzanje mrežnog stoga ADONIS-
a i S7-1200 PLC-a. Pokazat, ćemo skriptu u Ghidri koja automatski detektira funkcije
koje pripadaju određenom podsustavu OS-a. Također, pokazat ćemo kako smo riješili
problem da ne možemo koristiti debugger nad emulatorom koji je napravljen specifično
za S7-1200 PLC. Na kraju, pokazat ćemo naše spoznaje o mrežnom stogu ADONIS-a... More i
S7-1200 PLC-a. Less

Abstract (english)

In this paper we will show how we built specific tools to reverse engineering the
ADONIS operating system and how we used those tools to reverse engineer the network
stack of ADONIS and S7-1200 PLC. We will show a script made in Ghidra that automat-
ically detects functions that belong to a specific subsystem of the OS. We will also show
how we solved the problem of not being able to use a debugger on an emulator made
specifically for the S7-1200 PLC. In the end we will show what we... More found out about the
network stack of ADONIS and the S7-1200 PLC. Less
