About these open source software
Whonix
Whonix ™ realistically addresses common attack vectors.
An IP address is a label which is used to identify a computer on the Internet. A simple analogy is an IP address is similar to a car license plate.
Hiding IP addresses is technically difficult for software. There is always a risk of so-called IP leaks, whereby a user mistakenly thinks the IP address is hidden when it is actually not.
Whonix ™ is the best solution to prevent IP leaks because it uses a more solid technical design. IP leak issues that previously applied to other software were not applicable to Whonix ™ in a number of cases; see Whonix ™ Protection against Real World Attacks.
IP leaks are not the only issue that can break a user's anonymity. Other threats include time attacks, keystroke deanonymization and data collection techniques. Whonix ™ deploys numerous security mechanisms [archive] to mitigate such attacks.
Qubes OS
Qubes OS is a free and open-source, security-oriented operating system for single-user desktop computing. Qubes OS leverages Xen-based virtualization to allow for the creation and management of isolated compartments called qubes.These qubes, which are implemented as virtual machines (VMs), have specific:Purposes: with a predefined set of one or many isolated applications, for personal or professional projects, to manage the network stack, the firewall, or to fulfill other user-defined purposes.Natures: full-fledged or stripped-down virtual machines based on popular operating systems, such as Fedora, Debian, and Windows.Levels of trust: from complete to non-existent. All windows are displayed in a unified desktop environment with unforgeable colored window borders so that different security levels are easily identifiable.Tor Browser
Please do not torrent over Tor.Tor Browser will block browser plugins such as Flash, RealPlayer, QuickTime, and others: they can be manipulated into revealing your IP address.We do not recommend installing additional add-ons or plugins into Tor BrowserPlugins or addons may bypass Tor or compromise your privacy.
