Mangled Packet

Mangled Packet refers to an invalid packet in the ethernet and TCP/IP network. Instead of having its sound order or content, the packet is mangled or mis-ordered to confuse computers, firewalls, routers or any service present on the network or Internet. Notable software tools such as NMAP or Nessus can generate these types of mis-ordered / mangled packets to confuse and even shut down these devices. This is commonly associated with a type of network attack called a denial-of-service attack. Inadequate networks can be flooded with these types of network packets to confuse routers and computers. Sometimes, a mangled packet is used to open the network ajar and to see what other services are available when operators need to restart disabled devices.
