file-read:
- description: The file is parsed as a configuration file and its content is shown as error messages, thus this is not suitable to exfiltrate binary files.
code: |
LFILE=file_to_read
ltrace -F $LFILE /dev/null
file-write:
- description: The data to be written appears amid the library function call log, quoted and with special characters escaped in octal notation. The string representation will be truncated, pick a value big enough. More generally, any binary that executes whatever library function call passing arbitrary data can be used in place of `ltrace -F DATA`.
