\texttt{pySim}~\cite{welte_pysim_2024} is a Python-based toolset designed for interacting with \gls{sim} cards and their derivatives. It is developed and actively maintained by the Osmocom project, a community of engineers focused on open-source mobile communication tools. Osmocom is also responsible for related utilities such as \texttt{simtrace2}, a hardware and software solution for tracing \gls{sim} card communication, which is utilized in this thesis for trace collection.
The \texttt{pySim} suite comprises five primary scripts: \texttt{pySim-shell}, \texttt{pySim-read}, \texttt{pySim-prog}, \texttt{pySim-trace}, and \texttt{pySim-smdpp}. Among these, \texttt{pySim-shell} is the core component, offering an interactive shell interface to navigate the \gls{sim} card file system and issue application-specific commands. It supersedes the legacy \texttt{pySim-read} script, which only supports a limited subset of shell commands and is primarily used to extract commonly accessed data fields from \gls{sim} cards.

The \texttt{pySim-trace} script provides a tracing utility and protocol decoder for \gls{sim} card-related communication. It integrates with \texttt{SIMtrace2} to intercept and decode communication between a user device and the \gls{sim} card. This functionality is limited to passive recording and does not support active injection or modification of messages.
