Question
Rick works as a Computer Forensic Investigator for BlueWells Inc. He has been informed that some confidential information is being leaked out by an employee of the company. Rick suspects that someone is sending the information through email. He checks the emails sent by some employees to other networks. Rick finds out that Sam, an employee of the Sales department, is continuously sending text files that contain special symbols, graphics, and signs. Rick suspects that Sam is using the Steganography technique to send data in a disguised form. Which of the following techniques is Sam using? Each correct answer represents a part of the solution. Choose all that apply.

Why each option
Sam is using text-based steganography by embedding hidden data within special symbols, graphics, and signs, which falls under both linguistic steganography and text semagrams.
Linguistic steganography hides information within natural language text using semantic or syntactic methods, and the use of specific symbols and signs in text files is consistent with this category of text-based information hiding.
Text semagrams are a subtype of steganography that conceal messages by using visual elements such as special symbols, graphics, and signs within text rather than using conventional words, which directly matches the behavior Sam is exhibiting.
Technical steganography refers to methods that use physical or chemical means to hide messages (such as invisible ink or microdots) and does not apply to digital text file manipulation.
Perceptual masking is an audio steganography technique that hides data in sounds by exploiting human hearing limitations, not a method applicable to hiding data in text files with symbols.
