Exam PT0-002 topic 1 question 160 discussion

A. Steganography Steganography is the practice of hiding information within other data, such as images, audio, or video files. A penetration tester could use steganography to attempt exfiltration of data by hiding sensitive information within email attachments and then trying to send it through the email system. This test can be used to validate the effectiveness of the DLP product by attempting to detect if the DLP system is able to detect the hidden data before it gets exfiltrated. Option B, Metadata removal, doesn't actually help exfiltrating the data, it just removes metadata that could reveal information about the file. Option C, Encryption, is not effective for exfiltration since it's used to protect the data from being intercepted and read by unauthorized parties. Option D, Encode64, is a way to encode data in base64, but it doesn't hide the data, it can make the data unreadable but doesn't hide it.

From my work experience, both encryption would 100% trigger a DLP alert, so that rules out C and D. which only leaves A Steganography

A, the keys word in the question is are exfiltration in email attachments which I think stuffing data in images or other files rather than traditional encryption.

I think people rarely think of steganography, so the most straightforward and common way of filtering info, is encryption, think word document with password protection, so the DLP product can't inspect it.

Encryption involves transforming data into a coded format that can only be read or processed after decryption using a specific key. In the context of attempting data exfiltration via email attachments, encrypting the content of the attachments can be an effective way to bypass or test the DLP product's ability to detect sensitive data leaving the network. Steganography: Steganography involves concealing data within other data (like hiding messages within images or files). While it can be used for covert communication, it might not directly validate the DLP product's effectiveness in detecting sensitive data leaving the network via email attachments. read the question carefully. I believe C is the correct answer

A. Steganography Explanation: Option A: Steganography is the practice of hiding information within other non-sensitive information. By embedding the data to be exfiltrated within an innocent-looking file (such as an image), the tester can attempt to bypass the DLP's detection mechanisms. This would be an effective way to test whether the DLP product can detect such concealed exfiltration attempts.

Steganography is the practice of hiding secret information within another piece of data, such as an image, audio file, or video, in such a way that it is difficult or impossible to detect. While steganography can be used in combination with encryption, it is not a form of encryption itself. In the context of the question, the penetration tester wants to validate the effectiveness of a DLP (Data Loss Prevention) product by attempting exfiltration of data using email attachments. To accomplish this, the tester would want to use a technique that attempts to bypass the DLP product and successfully exfiltrate the data. Steganography, which involves hiding the data within another file, would not necessarily accomplish this goal on its own. Instead, the tester would want to use a technique such as encryption or encoding to attempt to bypass the DLP product and successfully exfiltrate the data. Therefore, the correct answer is C.

Steganography- Specifically the Steghide tool

A - Steganography. This is hiding of information within another data like images. The images can be sent out of the organisation using email system assuming there are policies against the use of external drives and USB devices.

ChatGPT agrees with RRabbit and kmanb....maybe RRabbit and kmanb are chatgpt!

All other answers are a form of encryption or randomizing the data.
