I had no idea what was going on until the last few moments. No idea what Capture the Flag had to do with Laravel. But you're actually playing Capture the Flag. Interesting.

Hi John, just need some knowledge that I am trying to figuring out recently, currently I am fiddling around with Java, and interesting thing I found about it was that Windows 10 does not check for Code Sigining of a Jar file but if I deploy a simple hello world written in C/C++, exe file on a different computer it detects it as a malacious file and does not let user to run it. What are the edge cases that will prevent someone from writting a Java based virus or a ransomware to go undetected by a security endpoint given the fact writing obfuscate code to prevent behavioural analysis by security.

A small clarification - the .env file is gitignored because different environments uses different .env values, and to keep this away from source control, but not because we want to exclude/hide it from a production environment. Of course, there are also other ways to set environment variables in a production runtime.

It's trick with named pipes (mkfifo). With some redirection magic you get an executable to be passed over nc. It's often used for reverse shells because /dev/tcp is a Bash only feature and nc -e is often disabled due to obvious reasons.

Sir, I want to build a booking website using php, html and css. If I don't learn javascript is it possible to make it
@JanBebendorf
@JanBebendorf 2 жыл бұрын
It's possible without javascript but it will completely suck. If you actually know php already, adapting to other languages should be no big problem. If you can't adapt you probably didn't actually understand the key concepts yet and you should dive into the very basics of DSA first.

What about simply reading /assets../.env? If that doesn't work, because we are speaking of php developers, there is always at least one route that can be easily forced into a 500 to get the debug screen and read the entire configuration from there.

When you get access to .env you have access to the db name user + password I think you could just try that for to ssh to the server
