How Do DDoS Attack?
DDoS attacks do not occur in a uniformed manner but most commonly traffic of DDoS come from multiple choices. It can come from army of hundreds of devices such as webcams, routers and thermostats. These devices are called a botnet – defined as a collection of devices connected through the internet, and being controlled by a common type of malware developed by smart hackers.

But it also possible to be the real DDoS attack. However, as a general rule you can tell the difference by the length of time of interruption in service. If it is just a glitch during a campaign then in general there should be nothing to worry about, but a DDoS effort would normally creeps slowly and take longer time to a few days. This is when you should be looking seriously into what has gone wrong.
There are also other ways to know if you are being the prime target of this vicious malware. Time to Live (TTL) means the control of the amount of time that data stays on a computer and removing data when passing the time interval. The malware will keep querying data when TTL has lapsed for a long time. It’s time to start worrying about a DDoS has taken place already.
