Nimda
Nimda is a computer worm, and is also a file infector. It quickly spread, eclipsing the economic damage
caused by past outbreaks such as Code Red. Multiple propagation vectors allowed Nimda to become
the Internet’s most widespread virus/worm within 22 minutes.
SYN Flood
A SYN flood is a form of denial-of-service attack in which an attacker sends a succession of SYN
requests to a target's system.
ICMP Flood
A smurf attack is one particular variant of a flooding DoS attack on the public Internet. It relies on
misconfigured network devices that allow packets to be sent to all computer hosts on a particular
network via the broadcast address of the network, rather than a specific machine. The network then
serves as a smurf amplifier. In such an attack, the perpetrators will send large numbers of IP packets
with the source address faked to appear to be the address of the victim. The network's bandwidth is
quickly used up, preventing legitimate packets from getting through to their destination.
UDP Flood
A UDP flood attack is a denial-of-service (DoS) attack using the User Datagram Protocol (UDP), a
sessionless/connectionless computer networking protocol.
Using UDP for denial-of-service attacks is not as straightforward as with the Transmission Control
Protocol (TCP). However, a UDP flood attack can be initiated by sending a large number of UDP
packets to random ports on a remote host.
Ping of Death
It is the attacks of tremendous trash data in PING packets that hackers send to cause System
malfunction. This attack can cause network speed to slow down, or even make it necessary to restart
the computer to get a normal operation.
IP Spoofing
Hackers disguise themselves as trusted users of the network in Spoof attacks. They use a fake identity
to try to pass through the firewall system and invade the network.
Port Scan
Hackers use to continuously scan networks on the Internet to detect computers and vulnerable ports
that are opened by those computers.
