Attack of the Tuxissa Virus
Written by James Baughn on March 29, 1999
from the more-powerful-than-y2k dept.
What started out as a prank posting to comp.os.linux.advocacy
yesterday has turned into one of the most significant viruses in
computing history. The creator of the virus, who goes by the
moniker "Anonymous Longhair", modified the Melissa virus to
download and install Linux on infected machines.
"It's a work of art," one Linux advocate told Humorix after he
looked through the Tuxissa virus source code. "This virus goes
well beyond the feeble troublemaking of Melissa." The advocate
enumerated some of the tasks the virus performs in the
background while the user is blissfully playing Solitaire:
Once the virus is activated, it first works on propogating itself. It
has a built-in email harvesting module that downloads all the
pages referenced in the user's Internet Explorer bookmarks and
scans them for email addresses. Using Outlook, the virus sends
a copy of itself to every email address it comes across.
After it has successfully reproduced, the virus begins the tricky
process of upgrading the system to Linux. First, the virus
modifies AUTOEXEC.BAT so that the virus will be re-activated
if the system crashes or is shut down while the upgrade is in
process. Second, the virus downloads a stripped-down
Slackware distribution, using a lengthy list of mirror sites to
prevent the virus from overloading any one server.
Then the virus configures a UMSDOS filesystem to install Linux
on. Since this filesystem resides on a FAT partition, there is no
need to re-partition the hard drive, one of the few actions that
the Word macro langugage doesn't allow.
Next, the virus uncompresses the downloaded files into the new
Linux filesystem. The virus then permanently deletes all copies
of the Windows Registry, virtually preventing the user from
booting into Windows without a re-install. After modifying the
boot sector, the virus terminates its own life by rebooting the
system. The computer boots into the Slackware setup program,
which automatically finishes the installation of Linux. Finally, the
dazed user is presented with the Linux login prompt and the text,
"Welcome to Linux. You'll never want to use Windows again.
Type 'root' to begin..."
The whole process take about two hours, assuming the user has
a decent Internet connection. Since the virus runs invisibly in the
background, the user has no chance to stop it until it's too late.
The email message that the virus is attached to has the subject
"Important Message About Windows Security". The text of the
body says, "I want to let you know about some security problems
I've uncovered in Windows 95/98/NT, Office 95/97, and Outlook.
It's critically important that you protect your system against
these attacks. Visit these sites for more information..." The rest
of the message contains 42 links to sites about Linux and free
software.
Slashdot is one of those links. "That could spell trouble," one
Slashdot expert told Humorix. "Slashdot could fall victim to the
new 'Macro Virus Effect' if this virus continues to propogate at
its present exponential growth rate. Red Hat's portal site,
another site present on the virus' links list, seems to be quite
sluggish right now..."
Details on how the virus started are a bit sketchy. The
"Anonymous Longhair" who created it only posted it to Usenet
as an early April Fool's gag, a demonstration of how easy it
would be to mount a "Linux revolution". Some other Usenet
reader is responsible for actually spreading the virus into the
wild. One observer speculated, "I imagine the virus was first
sent to the addresses of several well-known spammers. The
virus probably latched on to the spammer's email lists and began
propagating at a fantastic rate. With no boundary to its growth,
this thing could wind up infecting every single Net-connected
Wintel box in the world. Wouldn't that be a shame!"
Linus Torvalds, who just left for a two week vacation, was
unavailable for comment at press time. We have a strong feeling
that his vacation will be cut short very soon...
