How to Identify Steganography        
==============================   		  	
 	 	 			
Steganography is the practice of hiding secret information within 		 	   
ordinary, non-secret data or physical objects. Unlike cryptography, 		 	  	
which makes data unreadable, steganography conceals the very 			 	  
existence of the secret message. 		  	 	
 			  		
Common techniques include: 			    
- Least Significant Bit (LSB) embedding in images 		    	
- Hiding data in audio frequency spectrums 		   		
- Using invisible Unicode characters in text 		  	 	
- Appending data after file end markers  	     
- Encoding in metadata fields 		 	   
 		 	  	
Detection methods include statistical analysis, visual inspection 		  	  
of bit planes, frequency domain analysis, and file structure 		  	 	
examination. Tools like ST3GG can automate this process. 			  		
  	     
The word steganography comes from the Greek words 'steganos' 			  		
(meaning covered or hidden) and 'graphein' (meaning to write). 		  	 	
 		   		
In the digital age, steganography has found applications in 			  	 
digital watermarking, covert communication, and CTF challenges. 		  	 	
 			 	  
Always remember: just because you can't see it doesn't mean 			  		
it's not there. Hidden in plain sight is the ultimate disguise.
