A piece of CAKe

I don't know about you but I find pretty difficult to generate realistic traffic for testing. While existing tools such as the replayfilegen, perftestsyslog or bleep are nice I often feel they lack of flexibility. That's why I decided to write my own tool. CAKe (standing for CEF Army Knife experiment) is a python script that I define as a versatile CEF manipulation and generation tool.

CAKe can:

  • replay existing CEF events or generate partially random CEF events based on a customizable template
  • Modify timestamps of your CEF events. You can decide the timestamp(s) you want to modify and 4 modes exist:
    • realtime: you define the EPS you want and the timestamps are generated to simulate realtime events
    • customtime : you define a number of events and a time period (can be something like Now-1h:Now:100). Timestamps are created to spread your events equally all over this period.
    • keeptimestamp: keep existing timestamp
    • no timestamp: remove existing timestamp
  • generate different output for your new cef events
    • CEF files: events are simply stored in files.
    • CSV file: allows to get a human readable format for CEF events
    • Syslog: CEF events can be sent to a syslog connector in TCP or UDP
    • display: CEF events are directly displayed in your terminal
  • Modify CEF events content in multiple ways:
    • sanitization: it's possible to remove IPs or to randomize them. It's possible to remove CEF fields if the fieldname or the value contains a given string
    • extract: allows only keeping some CEF fields from a given CEF event
    • select/unselect: allows to keep only or remove CEF events containing a given pattern
    • add: allows adding some extra CEF fields
    • fix: a string search and replace function in the CEF event

If you are interested you can find a lot more details in the documentation. If you want to give it a try, please help yourself and have a piece of CAKe.

Since my name is MacGyver, I'm going to have to give this a try this week!

Any new updates to keep in mind?  Thank you!


Hi Paul,

This is the last version available. I know some people have been using it successfully but didn't get a lot of feedback to be honest so ... good luck with your testing 😉
