HTTPS & TLS Encryption

What does HTTPS stand for?

• Hyperlink Text Protocol System

• Hypertext Transfer Protocol Secure

• Home Entertainment Protection Service

• Highly Encrypted Privacy System

What is the purpose of Transport Layer Security (TLS) in HTTPS?

• To encrypt data between browser and web servers

• To display green padlocks on websites

• To track user browsing history

• To block access to certain websites

What percentage of the top 10,000 HTTPS sites were found to have potentially exploitable TLS vulnerabilities?

• 2.5%

• 10%

• 5.5%

• 8%

What type of vulnerabilities involve initiating the same query multiple times to slowly extrapolate information from small tells?

• Man in the middle attacks

• Tainted channels

• Full-on leaky bugs

• Partially leaky bugs

What is the main concern with 'tainted' channels in TLS vulnerabilities?

• Allowing attackers to decrypt traffic

• Enabling attackers to modify or manipulate traffic

• Exposing session cookies

• Displaying fake green padlocks

Why are TLS vulnerabilities in related domains a concern?

• They are easily fixed

• They only affect the main domain

• They can create a ripple of exposure in the overall population

• They can lead to website downtime

What is the goal of the researchers from Ca' Foscari University regarding TLS vulnerabilities?

• To exploit vulnerabilities for personal gain

• To shut down websites with vulnerabilities

• To develop a tool to identify overlooked TLS vulnerabilities

• To ignore the vulnerabilities

What does Kenn White emphasize regarding the TLS vulnerabilities found by the researchers?

• They are impossible to exploit

• They are critical vulnerabilities

• They are not appealing targets for hackers

• They are easily fixed by web developers

What is the significance of interdependencies in web security according to the researchers?

• They slow down website loading times

• They have no impact on security

• They amplify vulnerabilities across related domains

• They strengthen the security of websites

What is the ultimate goal of identifying TLS vulnerabilities in websites?

• To shut down the websites

• To improve overall web security

• To sell the vulnerabilities to hackers

• To increase website traffic
