HFNetchk written was by Shavlick and is available in Pro version here: http://www.shavlik.com/ Also, I noticed that there having a 'Get HFNetChkLT with Free Patch Pushing' event (http://www.shavlik.com/security/prod_gen_request.asp). There's also Ecor'a Patchmeister (www.ecora.com), which is free, but doesn't support patch pushing AFAIK. cheers, sunzi ----- Original Message ----- From: "zeno" <bugtraqat_private> To: "Mark Challender" <MarkCat_private> Cc: <pjat_private>; <incidentsat_private> Sent: Tuesday, September 24, 2002 2:28 PM Subject: Re: new IIS worm?
