# Cat ## Overview Hey everyone, in this write-up we will be solving an HTB challenge Cat. Link to the challenge: Let’s Start!!!!!! *** ## Initial Setup First download and extract the given file.
After extracting the zip, we can see a file named `cat.ab`. I used `file` command on the `Cat.ab` file.
From the output of the file command, we can conclude that the given file is android backup file. *** ## Extracting the Backup File You can extract file from a android backup using `android-backup-extractor`. Download it. {% embed url="" %}
Using the command: `java -jar abe.jar unpack cat.ab file.tar` , you can convert a android backup file to a tar file.
Now its time to extract the tar file using the command `tar xvf file.tar`.
From the output of the `tar` tool, we can see that there are some images in the `shared/0/Pictures` directory.
On taking a look at those images, one of the image contains the flag in it.
We have successfully obtained the flag. Thank you…….
