A corporate whistleblower wants to leak a document to a journalist without revealing the fact that any communication is happening. The whistleblower decides to hide the document inside a video file that will be uploaded to a public video-sharing platform. Which aspect of steganography is the whistleblower primarily relying on?

The concealment of the existence of the document within the video

The authentication of the video to prove its origin

The compression of the video to make it smaller for upload

The encryption of the document to prevent unauthorized reading

A digital forensics examiner is analyzing a set of image files that may contain hidden data. The examiner notices that some images have an unusually high number of unique colors and a noisy appearance in the blue channel. Which steganalysis technique would be most appropriate to confirm whether LSB steganography was used?

Visual attack by zooming into the image to look for patterns

Statistical analysis of the color histogram and bit-plane distribution

Metadata analysis to look for steganography tool signatures

Structural analysis of the file format to check for appended data

A small business owner wants to use steganography to protect sensitive client data that is shared with a partner. The owner is not technically sophisticated and needs a tool that is easy to use, supports common image formats, and allows the user to embed a message with a password. Which type of tool should the owner choose?

A command-line tool that requires manual compilation and configuration

A custom script written in Python that the owner must run from the terminal

A GUI-based steganography tool that supports drag-and-drop embedding and password protection

A hardware-based steganography device that requires specialized setup

A security team is implementing a steganographic detection system. They need to minimize false positives while maximizing detection of hidden data. Which approach is most effective?

Use a low detection threshold to maximize detection

Combine multiple steganalysis techniques and use a weighted scoring system

Use a single steganalysis technique that is known to be accurate

Use a high detection threshold to reduce false positives

A video editor wants to hide a watermark in a video file to prove ownership without visibly altering the video. The watermark must survive common video processing, such as recompression and format conversion. Which steganographic technique is most appropriate for this use case?

LSB insertion on the video frames

Palette-based embedding on the video's color palette

Spread-spectrum embedding that spreads the watermark across the video's frequency spectrum

Embedding the watermark in the video's metadata

Steganography and Steganalysis ECES Practice Questions (Page 8)

Part of the Applications of Cryptography domain, which makes up ~25% of our current practice bank. EC-Council does not publish an official question count, but from its 120-minute exam (~50–80 total, ~13–20 in this domain), expect 3–5 from this objective — we provide 42 practice questions to prepare you well beyond it.
