Website Fingerprinting at Internet Scale
The website fingerprinting attack aims to identify the content (i.e., a webpage accessed by a client) of encrypted and anonymized connections by observing patterns of data flows such as packet size and direction. This attack can be performed by a local passive eavesdropper – one of the weakest adversaries in the attacker model of anonymization networks such as Tor. In this paper, we present a n...
متن کاملDeep Learning Website Fingerprinting Features
Anonymity networks like Tor enable Internet users to browse the web anonymously. This helps citizens circumvent censorship from repressive governments, journalists communicate with anonymous sources or regular users to avoid tracking online. However, adversaries can try to identify anonymous users by deploying several attacks. One of such attacks is website fingerprinting. Website fingerprintin...
متن کاملOn Realistically Attacking Tor with Website Fingerprinting
Website fingerprinting allows a local, passive observer monitoring a web-browsing client’s encrypted channel to determine her web activity. Previous attacks have shown that website fingerprinting could be a threat to anonymity networks such as Tor under laboratory conditions. However, there are significant differences between laboratory conditions and realistic conditions. First, in laboratory ...
متن کاملPoster: Novel Website Fingerprinting Techniques
Web-browsing clients may choose to browse the web by using proxies with encryption to secure their privacy. An attacker watching the outgoing connection of such a client will not be able to know the content or destination of their packets, unless the attacker uses website fingerprinting. Website fingerprinting is the process by which an attacker identifies which server a client is communicating...
متن کاملDeep Fingerprinting: Undermining Website Fingerprinting Defenses with Deep Learning
Website fingerprinting enables a local eavesdropper to determine which websites a user is visiting over an encrypted connection. State-of-the-art website fingerprinting attacks have been shown to be effective even against Tor. Recently, lightweight website fingerprinting defenses for Tor have been proposed that substantially degrade existing attacks: WTF-PAD and Walkie-Talkie. In this work, we ...
