Hi,
i've just received a mail from 'MS Corp Security Section', with the
subject "New Critical pack", and an exe file- 'Upgrade111.exe'.
it states that this is the latest version of security update, and i
should run it (?!)
the msg looks *very* convincing and reliable. is it Ms policy to
send updates by mail, or is it some malicious mail?
What you're receiving is most likely the output of a computer
infected by one of several widely publicized, wide-spread, mass emailing
worms. The virus' authors have deliberately spoofed the Microsoft
information in the hopes of garnering more victims. This sort of email
has been very common for past few years. Some of 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]
Trojan.Xombe
http://www.symantec.com/avcenter/venc/data/trojan.xombe.html
Microsoft never has, does not currently, and very probably 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.

How to Tell If a Microsoft Security-Related Message Is Genuine
http://www.microsoft.com/security/antivirus/authenticate_mail.asp
Remember, any and all legitimate patches and updates are readily
available at
http://windowsupdate.microsoft.com/. You should develop
the habit of checking this site at least once a month to keep your
computer up-to-date. (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. You can also ask your ISP to take steps to preclude their mail
server from passing on such emails. Many ISPs have such filtering
capabilities.
