RUDY (R-U-Dead-Yet?)
====================

What is the RUDY Attack?

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. “Low and slow” attacks by directing long form fields to the targeted server. It is known to have an interacti, thus making it a user-friendly tool. It opens fewer connections to the website being targeted for a long period and keeps the sessions open as long as it is feasible. The amount of open sessions o the server or website making it una for the authentic . 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 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 project is for educational, testing and research purpose.

The RUDY attack opens concurrent POST HTTP connections to the HTTP server and delays sending the body of the POST request to the point that the ser are saturated. This attack sends numerous small packets at a very slow rate to keep the connection open and the server busy. This low-and slow attack behavior makes it relatively difficult to detect, compared to flooding DoS attacks that raise the traffic abnormally.

How to install and run rudy?

Using go install

Using directly go

Using go build

Commands

Attack a target

There are some options to change the rudy default behaviour

| Name | Description | Long flag | Short flag | Example value | Default value |
|:--------------------|:-------------------------------------------------------------------------|:-----------------|:-----------|:---------------------------------|:--------------|
| URL | The target URL to run the attack on. | --url | -u | | |
| Concurrent requests | The number of concurrent requests to send on the target. | --concurrents | -c | 4 | 1 |
| Filepath | Filepath to the payload to send. By default it's a random payload (1MB). | --filepath | -f | /somewhere/file | |
| Interval | Inter between the requests. | --interval | -i | 3s | 10s |
| Size | Random payload size to send. Used if no filepath given. | --payload-size | -p | 1GB | 1MB |
| Tor | Use TOR proxy to send the requests. | --tor | -t | socks5://tor_endpoint | |
| Header | Pass additional headers to the request, you can pass multiple headers. | --header | -h | Content-Type: application/json | |
| Method | Set the request HTTP method. | --method | -m | PATCH | |
| Protocol | HTTP : http1 (chunked), http2 (TLS), h2c (cleartext). | --protocol | | http2 | http1 |
| Insecure | Skip TLS certificate (lab / self-signed). | --insecure | -k | | false |

HTTP/1.1 vs HTTP/2 slow body

| Protocol | Flag | Framing | Typical target URL |
|:---------|:-----|:--------|:-------------------|
| HTTP/1.1 | --protocol http1 | Transfer-Encoding: chunked, 1-byte chunks | or |
| HTTP/2 | --protocol http2 | Content-Length + slow DATA frames over TLS | |
| h2c | --protocol h2c | Same as HTTP/2, cleartext (no TLS) | |

Examples (defensi / WAF lab):

Each concurrent worker uses its own client/transport so HTTP/2 sessions open separate connections (comparable to multi-connection HTTP/1 RUDY).

Configuration file

You can define a .rudy.yml file to statically define options then o it using CLI flags.

Run the testing server

It will start a server on the port :8081
