GCIH · Question #266
Which of the following DoS attacks affects mostly Windows computers by sending corrupt UDP packets?
The correct answer is C. Bonk. The Bonk attack is a legacy DoS exploit that crashes Windows systems by sending malformed, fragmented UDP packets that the OS cannot reassemble correctly.

Why each option
The Bonk attack is a legacy DoS exploit that crashes Windows systems by sending malformed, fragmented UDP packets that the OS cannot reassemble correctly.
Fraggle is a UDP-based amplification attack that reflects traffic off network broadcast addresses, not one that sends corrupt packets specifically targeting Windows.
Ping flood uses ICMP echo request packets to overwhelm a target, not UDP packets, and is not specific to Windows.
Bonk targets a vulnerability in how Windows TCP/IP stacks handle fragmented UDP packets - it sends corrupt or overlapping UDP fragments that cause the Windows networking subsystem to crash or become unresponsive, making it a Windows-specific DoS tool.
Smurf is an ICMP-based amplification attack that spoofs the victim's IP and broadcasts ping requests, not a corrupt UDP packet attack targeting Windows.
