mega polymorph netbios worm
mega polymorph netbios worm
Hello i coded some fuking bullsh.1t dangerous worm.
LOL!.
anyways here's the code:
Description:
1)it checks if another instance is running , if yes it kills itself. (mutex)
2)it creates 9 random numbers (0-9) the first is the number of lines the file has got , the others are random
3)it will write each line into a file between every file it generates a random string , also it writes a comment that has the username of the current user in it also for polymorphism
First Generation:
Command
=>Random
Comand
=>Random
Second Generation:
Command
Random
=>Random
Command
Random
=>Random
etc...
on every execution it generates a new file with a new code, with more lines
It saves the new generated code as a random batch file name, so there is no "virus remover " or something
-For startup it infects the explorer Shell entry, to the last written polymorph file
-Some Random comments for execution polymorphism will be generated
-Then it searches for every exe file and renames it to one random choosen with a batch extension
-it generates the mutex as "true"
-it copies the copy of itself with the random exe name it has choosen to system32 drivers folder
-it "melts" its first executed file , and hides its copies
-then it adds a runkey with the original name of the exe
-then it writes itself again into itself so it becomes bigger
-it camouflaggs itself as DOS config file by writing the standard DOS config in itself , deleting the old dos config , and copying itself as the config file
-it tries to infect some system cmd and batch file by typing the uninfected system file into itself and replacing the system file with itself
-the last infection process is to write itself into the userlogon script
-it generates a random IP adresse and tries to spread over netbios (through copying to default shares)
-it types a comment with the username into itself for polymorphism (some antivirs just detects the last line (i know crank))
-at last it sets his mutex to false so another instance can be running
Edit://
-infects now every command line filein the whole system32 tree
-random prefix for polymorph copy
Edit://
-Usb spread
-usb spread generation morphism
-invisible starting through vbs wscript shell
nice isnt it?
it was fuckn complexe to code it i think i got a headache lol
