NewApt Worm alert (hitting Listservs too!)

        A newsgroup/Listserv was hit with the NewApt Worm (so it is possible that
they are unknowingly sending the Worm to lots of their friends and other
Listservs.)  See below.

        This is from the Datafellows F-Secure Virus Information Pages:

NAME:             NewApt
ALIAS:             I-Worm.NewApt, W32.NewApt.Worm. Worm.NewApt
SIZE:                69632

            The NewApt worm appeared in the last few days (the middle of
December 1999.) The worm itself is a Windows PE executable file about 70Kb long.
It is transferred via the Internet in e-mail messages as an attachment. The name
of the attached worm copy is randomly selected from 26 variants (so you should
look for all of these!):
            panther.exe      farter.exe
            gadget.exe       boss.exe
            irngiant.exe      monica.exe
            casper.exe       saddam.exe
            fborfw.exe       party.exe
            cupid2.exe       hog.exe
            party.exe         goal1.exe
            bboy.exe         pirate.exe
            baby.exe         video.exe
            goal.exe          copier.exe
            theobbq.exe    cooler1.exe
            panthr.exe       cooler3.exe
           chestburst.exe   g-zilla.exe

          The infected message's subject is sometimes "Just for your eyes". Other
subject variants are possible: in some cases the worm puts "Re:" to the subject
line and adds some random text there.

       The message body contains lines in plain text format:

                    " he, your lame client cant read HTML, haha.
                     click attachment to see some stunningly HOT stuff"

        as well as in HTML format:

                     "Hypercool Happy New Year 2000 funny programs and
                     We attached our recent animation from this site in our mail!
Check it out!"

        When the infected message is received, one of the above texts is
displayed depending on whether recepient's e-mail browser supports HTML e-mail
format or not.

        When the attached executable is run by a user the worm gets control and
installs itself to the system. It copies itself with its current name (as the
worm arrived in email) to the Windows directory and registers this copy in system
registry in the "Run=" section:

                     'tpawen' = 'C:\WINDOWS\PANTHER.EXE /x'

        Note that the worm's name (here it is "PANTHER") is not always the same
and can be randomly selected by the worm (see the list above).

        To hide its activity the worm displays a fake error message:


        For those who cannot see an image in your email, a W95/W98  warning  pops
up - which REQUIRES you to click "OK" before proceeding -  and which says:

        "The dinamic link library giface.dll could not be found in specified path


 The second line in the above messagebox is the infected system's Windows system
directory name, 'Path' and 'SystemRoot' system variables.

       The worm then registers itself as a service process (not visible in the
task list) and stays memory resident as a hidden application. The worm's main
routines (there are two ones working in the background) then periodically scan
hard drives for Internet-related files (MS Mail, Outlook Express, Netscape
Navigator and other files), open these files, get  Internet addresses from there
and send worm copies to these addresses.

       Starting from 12th of June, 2000 the worm removes "Run=" string from
system Registry and does not install itself to system any more. So, this worm's
life-time is limited by that date. But copies of the worm left in a system after
12th of June may activate again if system date is set incorrectly.

       From 00:00 starting on 26th of December the worm tries to connect to
remote computer somewhere at Microsoft each 3 seconds. This is most likely done
to ping-bomb the server.

       Depending on its counters and some other conditions the worm tries to call
phone numbers randomly selected from its own internal list. These numbers seem to
belong to an unknown company.

        Note that the worm attempts to disguise itself as one of the MessageMates
- amusing animations created to be sent to people on various occasions. The
MessageMates' website now has a warning about the worm.  (The MessageMates
website had nothing to do with this worm.)

An awesome number of Word Macro variants have been released in the wild
(including modifications of previously known, older viruses.)  Check your
antivirus program provider's web site DAILY during the holiday season, as many
worms and viruses are programmed to mess up your PC on Christmas day and New
Years Day.
