Security Patch Emails!!!

[db199]

I have been receiving e-mails that are supposedly from
microsoft with subjects like "Newest Security Patch",etc.
that are quite large(156k) and they look official and say
the following or something like it: Microsoft Customer
this is the latest version of security update,
the "September 2004, Cumulative Patch" update which
resolves all known security vulnerabilities affecting MS
Internet Explorer, MS Outlook and MS Outlook Express as
well as three newly discovered vulnerabilities. Install
now to continue keeping your computer secure. This update
includes the functionality of all previously released
patches. "
It includes attachments. Are these real emails or are
they posing as microsoft to invade my computer. Does
microsoft ever email updates? Thanks for your help.

Greetings --

What you received is either a very common malicious hoax or the
output of a computer infected by one of several wide-spread, mass
emailing worms. The most widely-known are:

W32.Swen.A_mm
http://securityresponse.symantec.com/avcenter/venc/data/[email protected]

W32.Dumaru_mm
http://securityresponse.symantec.com/avcenter/venc/data/[email protected]

W32.Gibe_mm
http://securityresponse.symantec.com/avcenter/venc/data/[email protected]

Microsoft never has, does not currently, and never will email
unsolicited security patches. At the most, if, and only if, you
subscribe to their security notification newsletter, they will send
you an email informing you that a new patch is available for
downloading.

Information on Bogus Microsoft Security Bulletin Emails
http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/news/patch_hoax.asp

The mere fact that the above site was established this past April
should be evidence enough that Microsoft has long been aware of the
problem. Unfortunately, there's nothing Microsoft can do to force the
users of its products to use common sense or practice safe computing.

Any and all legitimate patches and updates are readily available
at http://windowsupdate.microsoft.com/. (Notice that this is the true
URL, rather than the bogus one that may have been contained in the
email you received.) Any messages that point to any other source(s) or
claim to have the patch attached are bogus.

You're receiving these emails because your email address is in
the address book of someone infected with a worm, and/or because you
posted your real email address somewhere on-line, either in a forum
accessible to the public and spambots, such as Usenet, or on an
untrustworthy web site that subsequently sold your address as part of
a mailing list. One thing you can do is notify _everyone_ with whom
you've ever corresponded via email that one or more of them may be
infected with a mass emailing worm, and should take the appropriate
steps.

There's probably no way of blocking all of the bogus messages, but
you can greatly reduce the number you get by creating a rule, based
upon the most commonly used subject lines, to delete the emails from
the server without ever downloading them.
