Denial of Service

Question

Which of the following network attacks relies on sending an abnormally large packet size that exceeds TCP/ IP specifications?

Options

APing of death
BSYN flooding
CTCP hijacking
DSmurf attack

Explanation

The ping of death attack sends malformed ICMP packets exceeding the maximum IP packet size of 65,535 bytes, causing target systems to crash or become unresponsive upon reassembly.

Common mistakes.

B. SYN flooding is a denial-of-service attack that sends large numbers of TCP SYN packets without completing the three-way handshake, exhausting server connection state tables rather than using oversized packets.
C. TCP hijacking (session hijacking) involves an attacker intercepting and taking over an established TCP session by predicting or sniffing sequence numbers, not by transmitting oversized packets.
D. A smurf attack is an amplification attack that spoofs a victim's IP address and sends ICMP broadcast requests to many hosts, generating a flood of responses directed at the victim, unrelated to packet size violations.

Concept tested. Ping of death oversized packet denial-of-service attack
