Attack Types
IP fragmentation attacks can take several forms. While they all exploit the breakdown of datagrams in order to overbear the target networks, there are some notable differences in how different attack vectors are executed.
UDP and ICMP fragmentation attacks - These attacks involve the transmission of fraudulent UDP or ICMP packets that are larger than the network's MTU, (usually ~1500 bytes). As these packets are fake, and are unable to be reassembled, the target server's resources are quickly consumed, resulting in server unavailability.
TCP fragmentation attacks (a.k.a. Teardrop) - Also known as Teardrop attacks, these assaults target TCP/IP reassembly mechanisms, preventing them from putting together fragmented data packets. As a result, the data packets overlap and quickly overwhelm the victim's servers, causing them to fail.

DooS --> Ataque de negação de serviço.
Ele tenta sobrecarregar o servidor para deixá-los indisponíveis aos usuários.
No UDP (protocolo de transporte desorientado a conexão) : Sobrecarrega o transporte de protocolos.
No NTP (tempo para redes) : sobrecarregam os tempos de sincronização.
No SNMP (gerenciador) : Sobrecarrega as informações prestadas ao UDP.
