Tor is a software suite and network that provides increased anonymity on the Internet. It creates a multi-hop proxy network and utilizes multilayer encryption to protect both the message and routing information. Tor utilizes "Onion Routing," in which messages are encrypted with multiple layers of encryption; at each step in the proxy network, the topmost layer is decrypted and the contents forwarded on to the next node until it reaches its destination.

Standing S0183
Reach is how much of ATT&CK this tool touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.

Threat groups761% tie · 22 values
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
