Conducting Forensic Analysis and Incident Response Using Cisco Technologies (CBRFIR) — Question 22

An investigator is analyzing an attack in which malicious files were loaded on the network and were undetected. Several of the images received during the attack include repetitive patterns. Which anti-forensic technique was used?

Answer options

• A. spoofing
• B. obfuscation
• C. tunneling
• D. steganography

Correct answer: D

Explanation

The correct answer is D, steganography, which involves hiding malicious content within other files, such as images, making it difficult to detect. The other options like spoofing and obfuscation relate to misleading identities or disguising data, while tunneling pertains to encapsulating data in another protocol, none of which directly relate to the hidden patterns in the images.
