# Challenge Name: 1597


## Detailed solution

Starting by cloning the repository

```
git clone http://git.ritsec.club:7000/1597.git/
```
```
ls -la
total 8
drwxr-xr-x 3 kali kali 100 Apr 11 14:35 .
drwxr-xr-x 16 kali kali 540 Apr 11 14:35 ..
-rw-r--r-- 1 kali kali 1 Apr 11 14:35 flag.txt
drwxr-xr-x 8 kali kali 260 Apr 11 14:35 .git
-rw-r--r-- 1 kali kali 44 Apr 11 14:35 README.md
```
flag.txt is empty and README.md has the text A git ```challenge series? Sounds fun.```

Let's check the.git folder

```
ls -la
total 20
drwxr-xr-x 8 kali kali 260 Apr 12 17:01 .
drwxr-xr-x 3 kali kali 100 Apr 12 17:01 ..
drwxr-xr-x 2 kali kali 40 Apr 12 17:01 branches
-rw-r--r-- 1 kali kali 262 Apr 12 17:01 config
-rw-r--r-- 1 kali kali 73 Apr 12 17:01 description
-rw-r--r-- 1 kali kali 23 Apr 12 17:01 HEAD
drwxr-xr-x 2 kali kali 300 Apr 12 17:01 hooks
-rw-r--r-- 1 kali kali 209 Apr 12 17:01 index
drwxr-xr-x 2 kali kali 60 Apr 12 17:01 info
drwxr-xr-x 3 kali kali 80 Apr 12 17:01 logs
drwxr-xr-x 15 kali kali 300 Apr 12 17:01 objects
-rw-r--r-- 1 kali kali 181 Apr 12 17:01 packed-refs
drwxr-xr-x 5 kali kali 100 Apr 12 17:01 refs
```
Let's check the log of git commits


We can see an old text in the flag.txt

```
Your princess is in another castle
```
Let's check the packed-refs

```
cat packed-refs
# pack-refs with: peeled fully-peeled sorted
b123f674a07eaf5914eda8845d86b5219fc1de11 refs/remotes/origin/!flag
dcc402050827e92dbcf2578e24f2cba76f34229c refs/remotes/origin/master
```
Let's check the **origin/!flag**


## Flag

```
RS{git_is_just_a_tre3_with_lots_of_branches}
