The document provides an overview of tools used for launching Denial of Service (DoS) attacks, which aim to disrupt the availability of networks or services. Various types of DoS attacks are discussed, including volume-based, protocol, and application layer attacks, along with tools such as LOIC, HOIC, Slowloris, and various UDP and ICMP flood attack tools. Additionally, the document highlights defense mechanisms like intrusion prevention systems and firewalls to mitigate these attacks.

1. Tools Used For DOS Attack

2. 1
Introduction to Tools used for DOS Attack
DOS attacks are malicious attempts to disrupt
the availability of a network or service.
Attackers use various tools to launch these
attacks, targeting vulnerabilities in the target
system.
Understanding the tools used for DOS attacks is
crucial for implementing effective security
measures.

3. Types of DOS attack
Volume Based Attacks . Includes UDP floods, ICMP
floods, and BPS(bits per second),GBPS(Giga bits per
second),spoofed-packet floods
Protocol Attacks . Includes SYN floods, fragmented
packet attacks, Ping of Death, Smurf DDoS, and
Packets per second(PPS)
Application Layer requests per second
Mainly dos attack are common in application layer,
Presentation layer , Transport layer and Network layer

4. 2
LOIC (Low Orbit Ion Cannon)
LOIC is a widely used tool for DOS attacks.
It allows attackers to flood a target system with
a high volume of traffic.
Attackers can use LOIC to coordinate attacks
by connecting to a command and control server.

5. 3
HOIC (High Orbit Ion Cannon)
HOIC is an upgraded version of LOIC.
It performs DOS attacks by using a
combination of HTTP, UDP, and TCP packets.
HOIC enables attackers to launch large-scale
attacks by utilizing multiple sources.

6. 4
Slowloris
Slowloris is a tool that exploits the way web
servers handle concurrent connections.
It sends partial HTTP requests to the target
server and keeps them open for as long as
possible.
Slowloris exhausts the server's resources,
causing it to be unresponsive to legitimate
requests.

7. 5
TCP/IP Stack Attacks
Tools like hping3 and Scapy can be used to
launch TCP/IP stack attacks.
These attacks exploit vulnerabilities in the
TCP/IP protocol stack.
Attackers can manipulate packet headers,
flooding the target system and consuming its
resources.

8. 6
UDP Flood Attacks
UDP flood attacks are launched using tools like
UDP Unicorn and UDP Blast.
These tools flood the target system with a high
volume of User Datagram Protocol (UDP)
packets.
UDP flood attacks overload the system's
network stack, causing it to become
unresponsive.

9. 7
ICMP Flood Attacks
ICMP flood attacks utilize tools like Ping of
Death and Smurf Attack.
These attacks send a large number of ICMP
Echo Request packets to the target system.
ICMP flood attacks can consume the target
system's bandwidth and processing power.

10. 8
Botnets
Botnets are networks of compromised
computers controlled by a central command and
control server.
Attackers use botnets to launch coordinated
DOS attacks.
Tools like Zeus, Mirai, and Reaper are
commonly used to create and control botnets.

11. 9
Reflection/Amplification Attacks
Reflection/Amplification attacks exploit
vulnerabilities in certain network protocols.
Tools like DNS Amplification, NTP
Amplification, and SSDPAmplification are
used for these attacks.
Attackers spoof the IP address of the target
system, causing it to receive amplified traffic
from multiple sources.

12. 10
Defense Mechanisms
Implementing proper network security
measures can help mitigate DOS attacks.
Intrusion Prevention Systems (IPS) and
Firewalls can detect and block DOS attacks.
Regular security audits and patches can help
identify and fix vulnerabilities that could be
exploited.
