Cyber Security for Absolute Beginners - 2022 Edition - Part 02 - Attacking Tor - The End-to-End Correlation Hack

The video tutorial explains the end-to-end correlation attack on the Tor network, highlighting how attackers can correlate traffic from the entry node to the exit node to identify users. It discusses the structure of the Tor network, including entry and exit nodes, and emphasizes the importance of using encryption like HTTPS or SSL to protect data. Despite these measures, Tor remains vulnerable to certain attacks, such as the tagging attack, where attackers modify initial connections to trace users. The video concludes by acknowledging the limitations of Tor in preventing these attacks.

What is the primary risk associated with the exit node in a Tor network?

• It can cause data loss.

• It can block access to certain websites.

• It can reveal the user's identity if the communication is unencrypted.

• It can slow down the connection.

Why is it recommended to use HTTPS or SSL when making initial requests in Tor?

• To reduce data usage.

• To bypass network restrictions.

• To ensure the entire communication is encrypted.

• To increase the speed of the connection.

What is the Tor network's approach to traffic analysis?

• Tor only protects against traffic confirmation.

• Tor tries to protect against traffic analysis but not traffic confirmation.

• Tor completely prevents traffic analysis.

• Tor ignores traffic analysis.

How can attackers confirm a hypothesis in an end-to-end correlation attack?

• By blocking the exit node.

• By monitoring random locations in the network.

• By encrypting the initial request.

• By measuring both incoming and outgoing traffic at specific locations.

What is a tagging attack in the context of Tor?

• An attack that causes data corruption.

• An attack that slows down the network.

• An attack that modifies the initial connection to trace users.

• An attack that blocks access to certain nodes.
