After I have done my work, I did a little research on this unusal e-mail
and find out is a Internet worm (W32/Hybris.gen@M) seems to come from
211.99.253.95 (looks like is come from China.... Hummm.. I dunno anyone
there... where the hack they get my e-mail address??).

        The 'net community is a bit like a large incestuous family.  Guh.
Okay, bad image there.  The deal here is that, when you participate in any
public forum, someone don't know is bound to drop your address in their
MTA's address book for whatever reason...and these worms typically exploit
that address book to their own ends.

        Speaking to the matter of people having your address without you
knowing, the weirdest situation was finding one of my PGP pubkeys on a
keyserver (I don't send my keys to keyservers since I revoke them every
six months and it's a PITA to track them down).  Turns out that copy of my
key had been PGP-signed and posted to the keyserver by someone at
NATO.INT.  Now *that* was peculiar since I don't know anyone in NATO.

So if you have received any mail that you can't tell where is it come
from, don't execute the attachments.... (even if it is come from soneone
you know, be caution..)

        Agreed and agreed again.  For me, it's got to the point where
every attachment I receive is given (for want of a better term) a digital
strip search.  Anything that looks even remotely hinky is tossed into a
"possible worm/trojan" compost pile and left there to ferment.
