0x50f13 / ddos

Simple dos attack utility

ddos

ddos--simple program to test ddos protection system
THIS PROGRAM PROVIDED FOR ONLY EDUCATIONAL PURPOSES

Support

The support of this program is currently stopped. The development of completely new toolkit is started at https://github.com/Andrewerr/ddos2

Compilation

$ ./build.sh release
Notice:Current build is not supported by some compilers.Download latest relase from here: https://github.com/Andrewerr/ddos/releases

Usage

$./ddos (HOST) (PORT) [options...]
HOST -- host to ddos
PORT -- port to connect,if set to 0 will try random ports
Options:

-r -- generate random packet
-u -- Use UDP
-p -- Use TCP
-t (THREAD COUNT) -- describes thread count,by default set to 5
-s (PACKET SIZE) -- set packet size
--http -- Make http request
--no-warnings -- ignore all warnings
--no-errors -- ignore errors
--no-wait -- Do not wait server to respond
--no-check -- Do not check server before starting ddos
--packetfile (FILENAME) -- load packet conents from file(Could be overrided with --http option)
--sleep (TIME) -- sleep between packets sendings (in milliseconds)

Examples

$ ./ddos some.boring.long.domain.net 80 -t 70 --no-wait --http
This will send packets some.boring.long.domain.net:80 without waiting for response using http request syntax in 70 threads.
$ ./ddos example.com 88 --no-check --no-wait -u
With this options program will send packets to example.com:88 without pre-start host check and without waiting for response.Program will use 5 threads. Program will use UDP protocol.

Updating

$ ./build.sh update

ddos's Issues

Segmentation fault if argument not supplied

If argument for key is not supplied leads to segmentation fault.
Example:
$ ./ddos example.com 80 -t

prepare.py add exception handling

Udp does not work with --no-wait option

Host checker protocol mismatch

Even if using UDP protocol host check is still running using TCP protocol

Memory allocation in loop

While dosing each thread make cyclic loop allocation.

On linux timeval has incomplete type

Looks like need to add sys/time.h into socket

Add optional sleep between packets send

Sleep between requests in each thread

Unknown option:

Building on Android/Termux/clang fails

Failed to build because of following errors:
-clang-5.0: option -march=native not supported
-ld: Undefined reference to pow (probably need to add -lm option)

Build failure (GCC 7.3.0)

Release build fails when compiling with GCC 7.3.0.
I didn't try debug build, but I guess the result will be the same

build log

Possible reason: some includes are missing

UPD: Tried these changes, but something in memcrashed.c is wrong

Make --no-status option

Because of issue #9 need to make status optional (it'll help optimization too)

build.sh add check whether pull were successful

Add check to builder whether git pull retuned zero status if not message that update must be done manually

No logo option in build.sh

Need to make option that will disable logo printing in build.sh

Abort trap(6) after long work of program

After long time working getting abort trap

Make normal ping for checking service(v1.2)

Write ping for checking whether target is online/offline

memcrashed doesn't seem to work correctly

Packets aren't send by program correctly.Also memcrashed module couldn't be complied on any systems except Mac OS X
