Appears that if it gets a 404 back from its intial unicode scans, it just keeps looking elsewhere. If the server responds with anything other than a 404 (such as a 403 IP Rejected, in this case...) It attempts to get the server to tftp a file named "admin.dll" from the scanning system. I pulled the admin.dll from an infected box and to my non-programming eyes, it appears to do at least the following (in no order): 1. Adds the guest account to the local Administrators group and then activates the account 2. Use the anonymous 3. Makes sure c$ is shared 4. Tries to mail a bunch of files. HELO it uses is aabbcc. <*** Might be able to use this for a quick and dirty IDS Sig***> 5. Looks like admin.dll ends up in "c", "d" and "e". 6. creates a file named readme.exe which is actually a wav file (weird?) I could be totally wrong here (and probably am) but oh well... Chris
