Hello, everyone. Today we're taking a look at the ESPACIO DOS virus.
This virus is actually quite large if we take a look at it.
We just do a directory listing - you'll see it's 28,498 bytes.
However, when we go ahead and run it...
We'll see that it's actually infected a twenty thousand byte GOAT file.
Sacrificial goat, so the actual size of the biruh- virus is pretty much 8,498 bytes.
So... 8.5 kilobytes from there. That's actually very large for a DOS virus...
um... especially one like this.
Normally, DOS viruses you see are probably under a thousand bytes. If it's a little more complex;
maybe a thousand or two thousand, and anything over that usually uses a lot of, um...
...polymorphism or self encryption or stuff like that, but this virus doesn't have any of that.
It's actually quite different and very entertaining. And so since we've run it we gotta wait about half an hour,
35 minutes. Maybe 45 minutes, and then we should see its payload activate.
So it infects COM and EXE files as they are run.
And it doesn't delete files, but it does something very fun which you'll see in just a bit, hopefully.
Okay, we'll be back when it does activate.
All right. Well. This is the first step in the virus getting to work.
Unfortunately it has hanged here. I'm not sure if you can see the color, but it is a nice cyan.
Oh well. I guess not I guess we're not gonna show it for very long.
...but it is a nice cyan color with a purple line in the center.
It might look quite a bit like some game you've seen before... and we will definitely be seeing it very shortly.
...as the virus will actually load up correctly and not crash as soon as it starts its payload.
[Entry of the Gladiators starts playing from the PC Speaker]
And here is the payload!
[Music finishes]
So you got the nice PAC-MAN title up there. Some Spanish text...
...basically. Copyright, NASA MAN 1993, so the virus is from 1993.
Although, you can't really copyright a virus. So we're supposed to press space to begin
Basically "in search of new adventures," so here we go. Press space and you play PAC-MAN.
Basically it's just a full-fledged Pac-man clone. I'm still dying-
[HAHA NO GAME FOR YOU]
Ah... Well, I guess sometimes it still crashes.
But if we give it long enough, I'm sure the virus will pop back up again. We'll be able to continue playing.
So we'll wait for that to happen and then we'll play.
Alright, and we're back with the ESPACIO virus.
And as you can see, it has now activated a stable version of our PAC-MAN game...
that we can play. As you can see from the text on the screen
I've lost a few times, so it's saying press space to "continue PAC-MANeando."
I don't know what that's about but... basically just press space to continue playing PAC-MAN.
So this popped up without crashing this time, and I was able to play a few games!
And I just want to make sure it wouldn't crash before I actually record it.
So we're going to go ahead and press space and play some more PAC-MAN.
So you get the nice, uhh... expletive instead of "READY" or "START" or "GO"
on the main screen. Whup - I apparently did not get the good pellet.
I am very bad at PAC-MAN, so don't worry about it - that's me.
I'm no Billy Mitchell.
But anyway, it plays almost exactly like PAC-MAN, although some of the ghost behaviors are a little odd.
They don't do exactly what you expect them to sometimes.
There is one nice thing about playing PAC-MAN on MS-DOS.
It's that with the keyboard buffer you can do put a key before you go in a direction...
...and it'll follow that direction.
So we're gonna press right and it'll go right as soon as it reaches a point where I can do that - which is quite handy.
All right, and it just goes on to another board which is pretty much the same thing.
I'll try to get some "maximum points."
Whup - got me.
And I guess I'm out of life - so we'll press space and play again
So this time, it's been pretty stable - hasn't crashed or anything. Which is nice.
It's always nice when viruses don't crash.
Aaaaand... we're just gonna play PAC-MAN for a while.
So as you can see, this is pretty much responsible for the huge virus size.
The program itself is actually packaged with 2K LITE(?) so... it's basically a self extractor
So when it's time to run the game, the virus will.. unzip it, basically, from its code
on the fly, and go to the play game routine.
Which is pretty funny. It doesn't destroy your data. It just makes you play a -
What!? I got that! I got that. That is bullshit. The game is cheating me.
I-I can see why you wouldn't want this virus now. It cheats.
You saw me get that pellet, too. I had it, I had it. That ghost did not get me.
Uh oh, uh oh.
That was fortunate.
I wanna know what the behavior would be if we just sit here for a bit.
Oh. They actually zeroed in on me pretty well.
I did that once where I just sit at the top and it, uh... just kind of went off on its own path and did whatever it
wanted to do. I'm gonna try playing with the colors just a little bit. Maybe a little less bright...
So it's a nice green background with the yellow pellets. You can see the red text...
And the ghosts actually have a bit of color. The only one you can really see in true color is Blinky.
Which is the red one.
Oh, what? I got that? It didn't count me getting the power pellet that one time.
What a piece of shit... oh, I'm sorry.
I shouldn't swear, but... this game cheats.
I'm terrible. I'm terrible at PAC-MAN. Maybe we should go somewhere where we can get a powerup.
I'm not good enough to be suicidal.
It's got nice sound effects... oh it's a candy cane. I want the- no!!
We're gonna play until we get the candy cane.
No, no! I got it. I got the powerup.
And then I went up
It's not fai- where are you going?
Okay, I guess the ghosts are doing their own thing. They'll be back in a bit- okay, c'mere.
C'mere...
Gotta look out for that candy cane. I want it-
No. NO! It did it again.
Stop doin' that.
This game...
...is just anticipating my moves too early.
I t's not me pressing the key too early, it's the game.
Oh-get it get it get it...
Yeah, that's a good sound effect.
All right now, get it... get the pellets...
We got it, we got it. We beat the level.
No-no! Get it! Ass... all right. We did it.
Apparently there's a watermelon in this level? I want the watermelon.
You can make it. You can make it! No! He made it. Damn.
Try again. One more time.
So this is about it for the ESPACIO virus.
Instead of making you play a game for your data
it just makes you play a game for the sake of playing a game.
And what better way to relax with a virus on your PC than with PAC-MAN?
I got it that ti- oh sheeee....
Get away from me!
Whatcha gonna do about it? You can't do anything.
Oh, that was fortunate. He's kind of going on his own way here again. Come down here.
Can I go out the top or go out the bottom and come out the top?
Yes we can, alright. That works.
So I guess this is just a fully functional PAC-MAN clone, kinda.
All the levels are the same which is kind of disappointing, but...
I'm guessing it's speeds up.
Oh, oh God! Run away!
Run awa- oh damn. Got trapped. Let's go again.
Get the watermelon... no no!
No, the watermelon's gone.
'Kay, what'cha gonna do about it? You can't do anything. No, stop being uneatable ghosts.
Get the watermelon! Yeaaah.
No, no, nope, no, no. Run away! Run away! Run away!!!
Oh, crap.
Okay, I suck at PAC-MAN, but there is one nice thing about this virus.
It actually doesn't force you to lose any work at all. If you hit control-alt-delete -
It's always scanning for that key combination - will return you to the last program you're running.
In this case, we were sitting at the DOS prompt.
So it doesn't cause you to lose any of your data by
forcing you to restart to get out of the game or anything like that.
So that is about it for the ESPACIO DOS virus.
And I hope you enjoyed this video as much as I enjoyed making it.
Oh crap. No! Don't go again.
Well, I guess no matter what you want to do...
you are going to play PAC-MAN.
We were trying to end the video here, but no. We're gonna play PAC-MAN. So... here we go.
This is the title screen. I wasn't sure I was going to be able to record this initially, but...
Well... here it is.
Hit space to play and it starts off the game once again
Okay, maybe it is an asshole virus 'cause no matter what you want to do
you're gonna play PAC-MAN, and you're gonna die a lot
Wonder how Billy Mitchell would fare with this version of PAC-MAN...
Okay, this time for real. This is the end of the ESPACIO DOS virus video...
And I hope you enjoyed watching it so as much as I enjoyed...
No no! Stop doing that!
I don't wanna play PAC-MAN. I wanna wrap up the video.
Why are you doing this to me? Every time it pops up, you gotta keep playing it.
Okay, one more time. One more time.
[Really fast] Okay, and that's about it for the ESPACIO DOS virus.
I hope you enjoyed watching it as much as I enjoyed making it
Thanks for watching, guys, bye-
NO. NO! Are you shitting me?
What?
Um...
I don't know how to end the video.
[REALLY fast] That'safortheESPACODOSvirusthankyoforwatchin.
No! Are you kidding me? How fast does it get?
[I'LL SHOW YOU! :D]
I guess it just gets faster and faster every single time you exit the program
until you can't get out of PAC-MAN anymore...
[HAHA YOUR SYSTEM CRASHED]
Oh, God. Oh, no, what did I do?
Oh, crap... okay. Now I guess seriously... it's the end of the ESPACIO DOS virus.
[danooct1 laughing uncontrollably]
Oh, goodness. [more laughing]
That's it. It's over it. That's the end. I can't do anything else, okay?
That's really it for the ESPACIO DOS virus, and I hope you enjoyed watching it.
