Captive Portal Evasion Tool
captiv8 is a (Linux only) captive portal evasion tool. It enumerates all BSSIDs that are part of a specified SSID and identifies STAs (clients) to masquerade as. While this could be used nefariously, IOT evade paying a subscription fee, the primary purpose and intent is to build a tool that allows for some anonymity on open networks and as a tool to test your captive portal or guest networks.
In short, captiv8 is an evil twin on the STA side.
