A Thousand Words
Description
A picture worth a thousand words...
Attachment: github.com.jpg
Solution
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 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 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.
