Core Mission

You can use these commands and rules to search for exploitation attempts against log4j RCE vulnerability CVE-2021-44228

This command searches for exploitation attempts in uncompressed files in folder /var/log and all sub folders

sudo egrep -I -i -r '\$(\{|%7B)jndi:(ldap[s]?|rmi|dns|nis|iiop|corba|nds|http):/[^\n]+' /var/log

	/*
	* This program demonstrates a simple Object-Oriented Programming (OOP)
	* approach in C using function pointers and structures. It renders pixel
	* effects onto an RGBA32 buffer using SDL2 for window management and display.
	*
	* Supported effects:
	* - Bitwise operations pattern
	* - Mandelbrot fractal visualization
	*
	* Key controls:

	Two pointers: one input, opposite ends

	```python3
	def fn(arr):
	left = ans = 0
	right = len(arr) - 1

	while left < right:
	# do some logic here with left and right
