FF-16-TUI (Find Frequent 16-bit Text User Interface)

What does FF-16-TUI do?

FF-16-TUI is an interactive static analysis tool that finds frequently occurring local 16-bit patterns across the entire file. It can help to locate structures from frequent patterns and understand file layout.

Text User Interface

Command line usage

ff-16-tui [filename] [-d <filename>]

  <filename>      Target file
  -d <filename>   Dictionary file  (Default: dict.csv)

Keyboard shortcuts

Hexdump panel:

Key	Function
←	Previous byte
→	Next byte
↑	Previous line
↓	Next line
PgUp	Previous page
PgDn	Next page
Home	Beginning of file
End	End of file

Pattern panel:

Key	Function
0	Highlight pattern (most frequent)
1	Highlight pattern
2	Highlight pattern
3	Highlight pattern
4	Highlight pattern
5	Highlight pattern
6	Highlight pattern
7	Highlight pattern
8	Highlight pattern
9	Highlight pattern (least frequent)

Filter panel:

Key	Function
q	Increase the minimum gap
s	Decrease the minimum gap
w	Increase the maximum gap
s	Decrease the maximum gap
e	Increase the minimum set bits
d	Decrease the minimum set bits
r	Increase the maximum set bits
f	Decrease the maximum set bits
t	Increase the threshold
g	Decrease the threashold

Terminologies

Term	Description
Ones	The number of bits set in the pattern.
Freq	The frequency of the pattern.
Dict	The dictionary entry for the pattern.
