Google "Hiccup"

We've gotten reports that Google was inoperable for a short period of time in the late hours of 06/06/2004 (GMT). We currently have no information on the cause of the outage.



CGI Email Script Scanning

From our mailbag comes a report by Michael Black at Essex Corporation who alertly noticed a distributed webserver scan for various email cgi-scripts:

There are several interesting things to note about this scan. It is obviously a distributed scan that, because of the tight timing involved, appears to be controlled by a one-to-many channel. An IRC controlled bot-net comes immediately to mind.

Scanning for these types of scripts seems to be a rather outdated practice, something that we haven't seen in some time. We found ourselves wondering about the value of finding such an installation vs. the effort expended in scanning for it.

If anyone else notices scanning of this sort, please pass the details along using our contact form: http://isc.sans.org/contact.php

NIST Publishes Guide For Securing Windows XP

The NIST (National Institute of Standards and Technology) has published,
in draft format, a guide for securing and administering Windows XP. They are soliciting for comments on this draft guide:



http://csrc.nist.gov/itsec/guidance_WinXP.html



Typically, NIST publications are well written and thorough. It is publication SP800-68, "Guidance for Securing Microsoft Windows XP Systems for IT Professionals: A NIST Security Configuration Checklist - Special Publication 800-68 (Draft)"



SANSFIRE

If you're on site at SANSFIRE in Monterey, please remember to stop by the IPNet booth and tell all of the ISC Handlers gathered there just how much you appreciate the fact that while they're off in California whooping it up, several of us are "back here" holding down the fort. Tell them that long, involved story about your first computer or, perhaps, show them that pesky rash that just won't go away. Sing them a song, or, better yet, tell a knock-knock joke. Everybody loves knock-knock jokes.
