599654 2007-10-09 07:52:00 I have a question about this code

{goto main;
1234567;
subroutine infect-executable := {
loop: file := get-random-executable-file;
if (first-line-of-file = 1234567) then goto loop else prepend V to file; }


What does it mean first line of file is 1234567?
I suppose get random executable file means that it will choose any .exe file..

Correct? 		Ninjabear (2948)

Look the whole thing in google - its the simple code for a virus - what AV do you have ? 		wainuitech (129)

599657 2007-10-09 08:52:00 Well, why DO you want to know anyway??

BUT one site I've found says this, I wont tell u where.

This example virus (V) searches for an uninfected executable file (E) by looking for executable files without the "1234567" in the beginning, and prepends V to E, turning it into an infected file (I).

V then checks to see if some triggering condition is true, and does damage.

Finally, V executes the rest of the program it was prepended to. When the user attempts to execute E, I is executed in its place; it infects another file and then executes as if it were E. With the exception of a slight delay for infection, I appears to be E until the triggering condition causes damage. 		Speedy Gonzales (78)
599658 2007-10-09 09:25:00 It's in one of the lecture slides of my paper.Thanks for the explanation Ninjabear (2948)
599659 2007-10-09 09:36:00 That's also pseudo-code, not a real program. Erayd (23)
