“Karta” (Russian for “map”) is a source code assisted binary matching plugin for IDA. The plugin was developed to match symbols for an open source library in a very large binary, usually a firmware file. For those who deal daily with firmware files, it’s a waste of time to have to repeatedly reverse net-snmp; there is a clear need for a tool to identify the used open sources, and automatically match their symbols in IDA.
