    A flaw in some Netgear router models is responsible for causing huge denial of service attacks - by accident

    Network hardware maker Netgear has warned its customers that a flaw in some of its router products that could set off an "accidental" denial of service (DoS) attack.

    The problem occurs because of a flawed implementation of the Network Time Protocol (NTP), which is a method commonly used by network devices to contact special "time" servers that pass on the correct time and date. This information is important for routers because they generate a variety of time-sensitive logs.

    The flawed routers work fine until the moment one of their periodic requests for the correct time goes unanswered. If for whatever reason the "time" server is unavailable, the flawed router will continue sending requests until it is answered.
