Support for Internet Relay Chat (IRC) protocol analysis.
base/protocols/irc/__load__.bro
Implements the core IRC analysis support. The logging model is to log IRC commands along with the associated response and some additional metadata about the connection if it’s available.
base/protocols/irc/dcc-send.bro
File extraction and introspection for DCC transfers over IRC.
There is a major problem with this script in the cluster context because we might see A send B a message that a DCC connection is to be expected, but that connection will actually be between B and C which could be analyzed on a different worker.
