AI-analyzed exploit summary The repository contains a functional Bash script that automates the extraction of Tor Browser activity (e.g., visited .onion sites) from a Windows memory dump using Volatility and Bulk Extractor. It demonstrates the information disclosure vulnerability by parsing process memory for HTTP requests and cache records.

Description

Tor Browser 9.0.7 on Windows 10 build 10586 is vulnerable to information disclosure. This could allow local attackers to bypass the intended anonymity feature and obtain information regarding the onion services visited by a local user. This can be accomplished by analyzing RAM memory even several hours after the local user used the product. This occurs because the product doesn't properly free memory.
