Attacks

Question 1

Fraggle attack

Answer 1

A form of denial-of-service attack similar to smurf, but it uses UDP packets instead of ICMP.

Question 2

smurf attack

Answer 2

A type of DoS. A smurf attack occurs when an amplifying server or network is used to flood a victim with useless data.

Question 3

teardrop attack

Answer 3

A type of DoS. A teardrop attack occurs when an attacker exploits a bug in an operating system. The bug exists in the routines used to reassemble fragmented packets. An attacker sends numerous specially formatted fragmented packets to the victim, which causes the system to freeze or crash.

Question 4

land attack

Answer 4

A type of DoS attack. A land attack occurs when the attacker sends numerous SYN packets to a victim and the SYN packets have been spoofed to use the same source and destination IP address and port number as the victim’s. This causes the victim to think it sent a TCP/IP session opening packet to itself, which causes a system failure, usually resulting in a freeze, crash, or reboot.

Question 5

malformed packet

Answer 5

The packet is actually wrong (malformed), meaning that a part of the packet is just not as expected (not following the protocol specifications). Dissector is buggy: The corresponding protocol dissector is simply buggy or still incomplete.”

Question 6

VLAN hopping

Answer 6

The ability to make network traffic jump between VLANs through an abuse of IEEE 802.1Q VLAN tagging known as double encapsulation.
