Website Fingerprinting using Traffic Analysis Attacks
Website fingerprinting is the act of recognizing web traffic through surveillance despite the use of encryption or anonymizing software. The overall idea is to leverage the fact that many web sites have specific request patterns, response byte counts, and other similar coarse features that are known beforehand. This information can be used to recognize and classify different website traffic des...
متن کاملMeasuring Information Leakage in Website Fingerprinting Attacks
Tor is a low-latency anonymity system intended to provide low-latency anonymous and uncensored network access against a local or network adversary. Because of the design choice to minimize traffic overhead (and increase the pool of potential users) Tor allows some information about the client’s connections to leak in the form of packet timing. Attacks that use (features extracted from) this inf...
متن کاملComparing Website Fingerprinting Attacks and Defenses
Website fingerprinting attacks allow a local, passive eavesdropper to identify a web browsing client’s destination web page by extracting noticeable and unique features from her traffic. Such attacks magnify the gap between privacy and security — a client who encrypts her communication traffic may still have her browsing behaviour exposed to lowcost eavesdropping. Previous authors have shown th...
متن کاملWalkie-Talkie: An Efficient Defense Against Passive Website Fingerprinting Attacks
Website fingerprinting (WF) is a traffic analysis attack that allows an eavesdropper to determine the web activity of a client, even if the client is using privacy technologies such as proxies, VPNs, or Tor. Recent work has highlighted the threat of website fingerprinting to privacy-sensitive web users. Many previously designed defenses against website fingerprinting have been broken by newer a...
متن کاملEffective Attacks and Provable Defenses for Website Fingerprinting
Website fingerprinting attacks allow a local, passive eavesdropper to identify a user’s web activity by leveraging packet sequence information. These attacks break the privacy expected by users of privacy technologies, including low-latency anonymity networks such as Tor. In this paper, we show a new attack that achieves significantly higher accuracy than previous attacks in the same field, fur...
