Place your signature in a file named “mysig.sig”. Then create another file called “myscript.bro”. Within this file, use the @load-sigs directive to load “mysig.sig”. When you run Bro be sure to tell Bro to include “myscript.bro”. You’ll also need to write an event handler for when your signature is matched.
