# Do You Know GIF?

Description :

```text
Ah, Dante! He appears in poems, videogames… He wrote about a lot of people but few have something meaningful to say about him nowadays.

Attached file : [dante.gif(14mb)]
```

The file size tempted me to check for the embedded files in the GIF using `steghide`,`stegoveritas` and `stegextract` and many more, but none of them was able to extract data.

Then tried exiftool on the `dante.gif`. Found a comment but it was not a flag. After trying all options on exiftool `-a` of exiftool loaded all the comments of `dante.gif` file.

```bash
mj0ln1r@Linux:/$ exiftool dante.gif | grep Comment
Comment : Hey look, a comment!
mj0ln1r@Linux:/$ exiftool -a dante.gif | grep Comment
Comment : Hey look, a comment!
Comment : These comments sure do look useful
Comment : I wonder what else I could do with them?
Comment : 44414e54457b673166355f
Comment : 3472335f6d3464335f6279
Comment : 5f626c30636b357d
Comment : At the edges of the map lies the void
```

Converted the hex strings to ascii to get the flag

```text
44414e54457b673166355f : DANTE{g1f5_
3472335f6d3464335f6279 : 4r3_m4d3_by
5f626c30636b357d : _bl0ck5}
```

> `Flag: DANTE{g1f5_4r3_m4d3_by_bl0ck5}`
