DNS Poisoning

All these DNS caches make a juicy target for hackers wanting to divert traffic using a DNS poisoning attack. For simple mischief, it's enough to edit the host files on the victim's device—which lives at /etc/hosts on Linux or at C:\Windows\System32\drivers\etc\hosts on Windows.

/etc/hosts

   # localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
127.0.0.1       localhost
