IP Spoofing

Usually, In IP spoofing or host file hijack, the malicious user masquerades as the legitimate host to gain access to an account or network or cause damage. Usually, the hijacker obtains the IP address of the real host and change packet headers; this way the real host appears to be the source.


Methods include faking the sending address of a transmission in order to gain illegal entry into a secure system, and making a website seem authentic to collect passwords and login names.

  1. to gain access to a resource or website they could not otherwise access
  2. to manipulate unsuspecting users to give them account login credentials
