Season's greetings from the Chaos Computer Club

So the 34. Chaos Communication Congress is currently in progress and the boys (and girls) attending were kind enough to send some thoughtful wishes to working sysadmins around the globe. The following entry appeared in my server log earlier today:

Is Mr. Robot at the Chaos Communication Congress?

So the “DELETE your logs” message hit my server last night and at first glance it does look like a HTTP DELETE request :-) A message from 32C3. However, this is not a delete request or even a valid HTTP request. Since I’m running ModSecurity it got rejected, but most servers will just throw a “400 Bad request” response. The user agent string “masspoem4u/1.0” identifies the messenger as a bot, and it’s probably misbehaving by design.
