That almost looks like one of the dummy user accounts that gets added as part of IIS. I see a couple of these on one win2k server that I maintain: "IWAM_<hostname>" (Launch IIS Process Account) "IUSER_<hostname>" (Internet Guest Account) Luke -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Brent_OKeeffe@asc.aon.com Sent: Monday, June 21, 2004 1:45 PM To: nanog@merit.edu Subject: Interesting Occurrence Okay... Here is a new one for me. Got a call from my dad saying he left his PC on last night connected to his broadband. He went to log in this morning and noticed a new ID in his user list - IWAP_WWW. He immediately deleted is and called me. I had him ensure his critical updates we all applied - they were. I had him ensure his antivirus was up to date - it was (Norton Antivirus 2004). He is running XP Home. I searched the antivirus sites and elsewhere for references. Any idea if there is a new vulnerability that has not been publicly released? Any clues? Regards, Brent
