Virus - 26/09/03 11:34 PM

I have a scripted virus for mirc on my computer, now i working on a cleaner for that virus, the problem is that the script have this line:

alias unload { /echo -ae *** Unloaded script ' $+ $2- $+ ' | halt }

and if you try to unload it it just do a echo then a halt, but the file is still there, and i cant get it to work with /!unload file.name .. any suggestions? smile

Re: Virus - 26/09/03 11:52 PM

No, i found it on the net.. this open sockets, then the dude that made it have entered stuff with halted events.. so if you do a /socklist then he have a alias that answwer on that.. and i wanted to get som suggestions how to UNLOAD the script/file.. but he have a alias that halt the unload command.. so i dont know how i can bypass the alias code, i writing a CLEANER that will remove the file, and also clear the %var's.. and make the victim be able to get free from this virus.. and this it only to help ppl.. if you dont know how to script or totaly new on this, then get this file.. then it wont help to reinstall your mirc.. and it wont help to just delete the files.. cos this crap writes to many files in ur system.. so i will clean them, then after thats done i want to unload the file.. and that makes the computer safe again.. the dude did this script to flood ppl with.. he have allot of commands like: !packet and stuff.. and it grabs the IP of the victim and start to flood it.. so i dont trying to make a virus.. i trying to make a thingie that REMOVES it.

Try this...
Code:
alias restore { alias $$1 }
Then you just use /restore unload

edit
Never mind, it won't work on aliases in remote scripts smirk

edit 2
Guess you could do something like..
Code:
alias restore {
  var %a = $+(",$isalias(unload).fname,")
  if $read(%a,w,alias*unload*) {
    write -dl $+ $readn %a
    .reload -rs %a
  }
}
The reason for the /reload is to stop warnings about "file X has changed.."

Re: Virus - 27/09/03 12:39 AM

Nope didnt work.. it still just show that echo.. and the file remain loaded in mirc.. and if i use /!unload filename then i get

* /unload: insufficient parameters

so dunno crazy

Re: Virus - 27/09/03 12:41 AM

Use /!unload [color:red]-nrs file.name[/color].
Posted By: sparta

Re: Virus - 27/09/03 12:45 AM

Nope.. that didnt work ether..

* /unload: invalid switch

and it dosent mather how i try, that file is loaded befor the "clean" file i doing.. so it takes that unload alias first.. so i cant get it to like ignore the alias in the first file.. so dunno how i can make it unload the file in a safe way.. smirk

alias remote { .remote $1- | .remote on | /echo -ae *** Remote is $1- }

as u see he have made it like it should look like your remote is set off.. but he temper with every damn alias command.. or make them act like he wants.. so dosent mather if you type /remote off, it still will be set on.. same for all commands i can think off.. and i cant get the damn thing to ignore the alias in hes file.. and i cant unload it in any easy way..

Re: Virus - 27/09/03 12:56 AM

Try removing the n switch then, if you're on an old version (pre v5.91) of mIRC.

Re: Virus - 27/09/03 01:09 AM

If you use the code in my second edit, you should then be able to use /unload -rs "filename" (no "!")
Posted By: sparta

Re: Virus - 27/09/03 01:35 AM

nope.. tryed it.. didnt remove anything.. and it didnt reload the file, and no error in the status win..

and if your code should work.. shouldent it look true the files in mirc dir and then check for the "alias unload" ? i cant see that it doing that ether.. and it dont show anything in the debug window or in status.. it doing somthing, but not the thing i want it to do smile

Re: Virus - 27/09/03 01:41 AM

This is what I did to test it..
In script3.mrc I put
Code:
<a bunch of code>
alias unload {
  echo -s * blah
  halt
}
<a bunch more code>
In a different script I had
Code:
alias restore {
  var %a = $+(",$isalias(unload).fname,")
  if $read(%a,w,alias*unload*) {
    write -dl $+ $readn %a
    .reload -rs %a
  }
}


Then, I typed //restore | unload -rs "D:\mIRC files\m610\Scripts\script3.mrc"
The result:
-
* Unloaded script 'D:\mIRC files\m610\Scripts\script3.mrc'
-

Re: Virus - 27/09/03 01:48 AM

All i get is the echo from the file i want to unload frown by the way, its a ini file..

Re: Virus - 27/09/03 01:52 AM

then use
if $read(%a,w,*=alias*unload*) {

in the restore alias. smile

Re: Virus - 27/09/03 01:55 AM

* /if: 'unload' unknown operator (line 97, script.mrc)

that mrc file is my script i writing on.. so ignore that wink
and i added the line so now it look like

Code:
alias restore {
  var %a = $+(",$isalias(unload).fname,")
  if $read(%a,w,*=alias*unload*) {
    write -dl $+ $readn %a
    .reload -rs %a
  }
}

Re: Virus - 27/09/03 01:56 AM

Or better..
Code:
alias restore {
  var %a = $+(",$isalias(unload).fname,")
  if $read(%a,w,alias*unload*) || $read(%a,w,*=alias*unload*) {
    write -dl $+ $readn %a
    .reload -rs %a
  }
}
..and cover both possibilities. smile

Re: Virus - 27/09/03 01:58 AM

Same error on that one.. "and yes, remote is on"

That is not from that code. What is line 97?:)
Posted By: sparta

Re: Virus - 27/09/03 02:05 AM

if $read(%a,w,alias*unload*) || $read(%a,w,*=alias*unload*) {

thats line 97 in my script file.. have search fetures and stuff to find the file i want to unload abow.. no reason to try to clean a file if its not there.. i can put the script in the top if u like.. but it would give the same error..

* /if: 'unload' unknown operator (line 3, script.mrc)

when i puted it in the start of the file..

alias restore { <<-- line 1
var %a = $+(",$isalias(unload).fname,") <<-- line 2
if $read(%a,w,alias*unload*) || $read(%a,w,*=alias*unload*) <<-- line 3
{

Re: Virus - 27/09/03 02:07 AM

/!unload -nrs "C:\path\to\script"

That will definitely work, providing the path you specify is to a file that has been loaded into remotes. Make sure you are specifying the right path, if it has spaces then enclose it in quotes. Type:

//var %i 1 | while $script(%i) { echo -a %i - $ifmatch | dec %i }

To see the full filenames of your loaded scripts

Also: for the unknown operator error use if $read(...) != $null {

{
If I leave it like that (with the brace in the wrong position), I get "insufficient parameters" error, but not an "unknown operator"

* /unload: invalid switch

i didnt belive it could be so hard to unload a file with a damn alias in it.. frown

Re: Virus - 27/09/03 02:17 AM

I just took the lines that was abow the error.. then that litle felow come with it wink whole code look like

Code:
alias restore {
  var %a = $+(",$isalias(unload).fname,")
  if $read(%a,w,alias*unload*) || $read(%a,w,*=alias*unload*) {
    write -dl $+ $readn %a
    .reload -rs %a
  }
}


just count the lines, line no: 3 is the one i have a problem with..

Re: Virus - 27/09/03 02:22 AM

Well, I don't know what is wrong, here it works exactly as I posted above, it unloads the script...
Posted By: sparta

Re: Virus - 27/09/03 02:24 AM

did you add a line in the script you trying to unload

This line:
alias unload { /echo -ae *** Unloaded script ' $+ $2- $+ ' | halt }

and i using mirc 6.03 dont know if that should interfare with the code, just an idea
Posted By: Iori

Re: Virus - 27/09/03 02:27 AM

I added it like I posted in this post
Posted By: Iori

Re: Virus - 27/09/03 02:40 AM

Hm you know, I was using 6.1. Just tried with 6.03 and it doesn't work, although I don't get any errors.
Posted By: Iori

Re: Virus - 27/09/03 03:28 AM

//.timer 1 0 !unload -rs "filename.ini" <- worked in 6.03 & 6.1 grin

Re: Virus - 27/09/03 03:52 AM

or manually open your mirc directory find the file called mirc.ini
scroll thru it and find a section that looks like this

[afiles]
n0=aliases.ini
[rfiles]
n0=remote.ini
n1=remote.ini
n2=script.ini

remove the name of the .mrc file from that list under [rfiles]

only do this with your mirc CLOSED... once done restart it and then u should be free from that. DONT forget to DELETE the BAD file from your pc

Re: Virus - 27/09/03 03:57 AM

The point is to do it from a script, a scripted "cleaner" for this file.. wink.

Re: Virus - 27/09/03 03:58 AM

ah thats why blush.
i just tried a test on removing the filename from that list with mirc open, it didnt work.

Re: Virus - 27/09/03 06:19 AM

I still have to unload it.. smile and i want to make shure the file is unloaded, then i wanted to clear the %variables that was set.. and we solved that. so now my addon is complete smile
