Hey guys, I have calculated the “dark matter” from the website. But the system told me i got a wrong flag when i submit it. Is is a fake flag? If it is, let me know,plz.Thanks.
Sorry. I realize that I made a mistake in my script. I finnally got the flag after i fix the bug. It’s a really nice web challenge
Hello All
I spend lot of times for this challenge
I have requested the app with the good ‘parameters’
I have encoded, and have escaped the dumb chars
And now nothing in the return page, nothing new except the original source code
I check the cookies nothing 
But with Burp I make a ‘time.sleep’ with success 
Need help please
if you can make it sleep, you’ve got one technique you can use to get information when you are ‘blind’
Ok Thanks for your answer
I’ll already test with time.sleep()
and that works
but we can’t make some os.system or popen requests ?
It looks like more Hard than easy challenge
