Apparently, the Code Red worm still attempts accessing my web server, but since it only affects Microsoft IIS web servers (and I run Apache 1.3.20), it has completely no effect, requesting
default.ida, and producing strings like the following in the error logs:
File does not exist: c:/apache/htdocs/default.ida
as well as the following line in the access logs:
90%u00c3%u0003%u8b00%u531b%u53ff%u0078%u0000%u00=aHTTP/1.0" 302 286
Oh, well. No harm done, I guess.
