R.U.D.Y., short for R U Dead Yet, is an acronym used to describe a Denial of Service (DoS) tool used by hackers to perform slow-rate a.k.a.
The amount of open sessions overtires the server or website making it unavailable for the authentic visitors.
The data is sent in small packs at an incredibly slow rate; normally there is a gap of ten seconds between each byte but these intervals are not definite and may vary to avert detection.
The victim servers of these types of attacks may face issues such as not being able to access a particular website, disrupt their connection, drastically slow network performance, etc.
This attack sends numerous small packets at a very slow rate to keep the connection open and the server busy.
