Anti-Inspect

Description

can you find the answer? WARNING: do not open the link your computer will not enjoy it much. URL: http://litctf.org:31779/

Hint: If your flag does not work, think about how to style the output of console.log

Solution

Straightforward question. I used curl to response from the website.

curl http://litctf.org:31779/

The response had the const flag on the js code which was running infinitely… that’s why the warning was given. ( and the computer was like why am I here? just to suffer? )

const flag = "LITCTF{your_%cfOund_teh_fI@g_94932}";
while (true)
console.log(
    flag,
    "background-color: darkblue; color: white; font-style: italic; border: 5px solid hotpink; font-size: 2em;"
);

I modified the script to run without the infinite loop.

Run the original js code with console.log() to get the flag. ( or just remove the %c )

Flag : LITCTF{your_fOund_teh_fI@g_94932}
