Die Analyse mit mmls dient der genauen Bestimmung der Partitionsstruktur und der Start-Offsets, was erforderlich ist, um gezielt Dateien zu extrahieren und das Dateisystem forensisch korrekt zu analysieren.

Analyst: Niklas Heringer Timestamp: 2025-07-14T20:40:59.996144+02:00

[!] Note: This command was executed with administrative rights (sudo). mkdir creates a directory. In forensic workflows, it is often used to prepare target folders for mounts or exported data.

The -p option ensures that parent directories are created as needed. It also avoids errors if the target directory already exists.

[!] Note: This command was executed with administrative rights (sudo). mount is used to attach a filesystem to the directory tree. In forensic contexts, it must be used cautiously, as mounting can alter timestamps or content.

The -o option sets mount parameters — e.g., to enable read-only mode or suppress timestamp changes.

ro stands for "read-only". It ensures that the mounted filesystem is not modified. This is critical in digital forensics.

tar is used to create and extract archive files. In forensics, it’s useful for packaging or reviewing archived evidence sets.

Analyst: Niklas Heringer Timestamp: 2025-07-14T20:41:00.238957+02:00

[!] Note: This command was executed with administrative rights (sudo). mkdir creates a directory. In forensic workflows, it is often used to prepare target folders for mounts or exported data.

The -p option ensures that parent directories are created as needed. It also avoids errors if the target directory already exists.
