Easy Community Administration Protocol (SNMP) and Network Time Protocol (NTP) can also be exploited as reflectors within an amplification attack. An illustration of an amplified DDoS attack through the NTP is thru a command termed monlist, which sends the small print of the last 600 hosts which have requested enough time in the NTP server back again into the requester. A small request to this time server is often sent utilizing a spoofed source IP handle of some victim, which leads to a response 556.9 times the scale of the ask for currently being sent into the sufferer.
