Interesting to note a few things here. First, NIPC is sharing information with specific vendors. They are not witholding who reported the information to NIPC to begin with. The vendor is then contacting them, using their information, and sending it out to the customers without giving credit.

Ok, this is just funny. So I sent part of that mail message I tossed to the list last night to "firstname.lastname@example.org." In that message I mention:
========================================================================== - Symantec has this worm at a removal level of "easy." If you think formating your servers and re-installing the OS is easy (or if you have tripwire running), then I guess this rating might be accurate. But if you are like most of us in the field, once you realize how many files this thing has torqued you are going to cringe. Which brings me to: - This worm attaches itself to a ton of files .EXEs. .HTMs. .DOCs. - there may be many more. So far, I've seen it hit targeted files as well as random ones. Among the targeted ones, it appears to consistently nail netmeeting's conf.exe, hyperterm, mediaplayer, wordpad, etc. It also hits random files, as it has attached itself to a copy of "putty.exe" that I set aside on a shared drive. It appends itself to these files so that it can lurk, and (hopefully) be launched at a later date. All of these file attachments could be random, I haven't performed analyses on enough machines to tell, but the thing the masses can take away from this is that this thing modifies files and data - it doesn't just deface sites, and chew up bandwidth, like other worms. In short, it will cost more to correct, and could really mess with people's data. NO ONE SEEMS TO BE REPORTING ON THIS. ==========================================================================
Then this morning I received the following from a Symantec dude - I can only imagine that he got this via NIPC:

Certainly not easy. - Vincent Symantec Security Response ==========================================================================
A few hours later, I receive the below message from the Symantec PR machine. Thanks for the news flash guys. Sheeze.-Greg

To: email@example.com Subject: SYMANTEC PROVIDES COMPREHENSIVE PROTECTION AGAINST W32.NIMDA.A@MM Dear Greg, Symantec Corporation, a world leader in Internet security, today announced that new analysis of W32.Nimda.A@mm reveals that the worm contains an additional destructive payload that will not only require detection, but removal. Please find below the complete press release. Please don^“t hesitate to contact me for further information. Regards, Sherri Walkenhorst Connect Public Relations (801) 373-7888 firstname.lastname@example.org News Release FOR IMMEDIATE RELEASE CONTACT: Yunsun Wee Sherri Walkenhorst Symantec Corporation Connect Public Relations (310) 449-7009 (801) 373-7888 email@example.com firstname.lastname@example.org SYMANTEC PROVIDES COMPREHENSIVE PROTECTION AGAINST W32.NIMDA.A@MM New Analysis of Computer Worm Indicates Additional Destructive Payload CUPERTINO, Calif. ^÷ Sept. 19, 2001 ^÷ Symantec Corp. (Nasdaq: SYMC), a world leader in Internet security, today announced that new analysis of W32.Nimda.A@mm reveals that the worm contains an additional destructive payload that will not only require detection, but removal. The new analysis indicates that the worm is a file infector, infects .exe files resides in memory. W32.Nimda.A@mm is a mass-mailing worm that utilizes multiple methods to spread itself. The worm sends itself out by e-mail, infects machines over the network, and infects unpatched or already vulnerable Microsoft IIS Web servers. The worm also has various side effects, such as increasing network traffic while searching for machines to infect, which may cause network bandwidth problems. W32.Nimda.A@mm will also attempt to create security holes by creating a guest account with administrator privileges and create open shares on the infected system. Symantec currently provides an integrated detection and repair solution against W32.Nimda.A@mm. In one step, users can download a solution that will simultaneously detect the worm and repair damaged files. The new definitions are available through Symantec^“s LiveUpdate feature or from the Symantec Web site www.securityresponse.symantec.com/avcenter/download.html. Symantec is developing a separate removal tool to eradicate the worm from the PC memory. ^”Using blended Internet security threats ^÷ the combination of viruses, exploits, or vulnerabilities ^÷ to attack businesses and destroy assets, continue to rise,^‘ said Vincent Weafer, senior director of Symantec Security Response. ^”To combat such a fast spreading threat, Symantec integrated its solution for W32.Nimda.A@mm to detect and repair, allowing for quick clean up with little downtime.^‘ Symantec Security Response recommends that IT administrators implement the following to stop the propagation of W32.Nimda.A@mm: ∑ Block e-mails containing a ^”readme.exe^‘ attachment. ∑ Update virus definitions and ensure that firewalls are correctly configured. ∑ Download the latest security updates for Enterprise Security Manager and NetRecon. ∑ Install the IIS Unicode Transversal security patch. ∑ Install the malformed MIME header execution security patch. ∑ Close network share drives. Additionally, consumers can immediately protect themselves against the new worm by implementing the following: ∑ Use Symantec^“s LiveUpdate feature to obtain the latest virus definitions. ∑ Use the Windows Update feature located on the ^”Start^‘ menu on Window 95 and higher systems to download new security patches. ∑ Disable the ^”File Download^‘ feature in Internet Explorer to prevent compromise. Both consumers and enterprises can be infected through a variety of methods. ∑ E-mail ^÷ One of the methods the worm uses to infect PCs though is e-mail. The e-mail arrives with an attachment ^÷ readme.exe that is not always visible and contains a randomly generated subject line and no body message. The worm uses its own SMTP engine to e-mail itself out to all the addresses it collects by searching the user^“s incoming and outgoing e-mail boxes. Internet Explorer users v5.01 or v5.5 - (IE 5 with the Service Pak 2 or later installed or IE 6 are not affected) will receive a blank e-mail ^÷ no subject line, no body and a hidden attachment. Just opening the e-mail can infect users^“ PCs. For the latest Microsoft security patch, visit http://www.microsoft.com/windows/ie/download/critical/q290108/default.asp. ∑ Shared Drives ^÷ PC users with shared drives enabled are also at risk. The worm searches for open network shares and will attempt to copy itself to these systems and then execute. IT administrators should close all network shared drives. ∑ Web sites ^÷When users visit a compromised Web site, the server will run a script attempting to download an Outlook file, which contains the W32.Nimda.A@mm worm. The worm will create an open network share on the infected machine allowing access to the system. W32.Nimda.A@mm specifically targets versions of IIS servers, taking advantage of the known Universal Web Traversal exploit (MS Security Bulletin MS00-078), which is similar to the exploit used in the Code Red attack. Compromised servers will display a Web page and attempt to download an Outlook file that contains the worm as an attachment. IT Administrators should download the Microsoft security patch for IIS 4.0 at http://www.microsoft.com/downloads/Release.asp?ReleaseID=32061 and for IIS v5.0 at http://www.microsoft.com/downloads/Release.asp?ReleaseID=32011. Symantec provides additional protection against W32.Nimda.A@mm through the following solutions: ∑ Enterprise Security Manager ^◊Symantec's policy compliance and vulnerability management system, helps manage security patch update functions. New patch templates are available that detect the underlying vulnerability on Windows NT 4.0 and Windows 2000 servers. ∑ NetProwler ^÷ Symantec's network-based intrusion detection tool, with Security Update 8 installed, is capable of detecting attempts to attack IIS 4.0 and 5.0 servers through this vulnerability. ∑ NetRecon ^÷ Symantec^“s network vulnerability assessment tool will be updated to detect if this vulnerability exists on a system and if so will provide recommendations on how to fix it. ∑ Symantec Enterprise Firewall (Raptor Firewall) ^÷ Symantec's application inspection firewall, by default, blocks suspect outbound data traffic from web servers, like IIS, when operating on the firewall's service network, thereby stopping the propagation of this, as well as other types of attacks. ∑ Symantec Security Check ^÷ This service, www.symantec.com/securitycheck, has been updated to scan if a system is vulnerable to this exploit. ∑ Norton Internet Security ^÷ Symantec^“s integrated security and privacy suite for consumers can be updated to ensure only trusted programs access the Internet. For detailed information about this threat, visit Symantec^“s Web site at www.symantec.com.
