Attachment: `github.com.jpg` ## Solution ``` strings github.com.jpg ``` Use `strings` command to view the printable text of the image.

We can see that there is a line which is related to SKRCTF and flag. Since the image name is `github.com.jpg`, it kind of gives us a hint that this might be a URL.

Go to the [website](https://github.com/Hong5489/SKRCTF/blob/master/flag.jpg) and we will see that there is another image. Download and analyze it.

By using the same command which is `strings`, we will notice that there is a suspicious cipher in the last line of the image.

Put it into [CyberChef](https://gchq.github.io/CyberChef) and decipher it. CyberChef is a useful tool for CTF players for cryptographic operations like decoding and decrypting. By decoding 3 times of Base64, the flag will be shown in the output section.
