Which of the following DoS tools is used to attack target web applications by starvation of available sessions on the web server? The tool keeps sessions at halt using never-ending POST transmissions

Stacheldraht is a classic distributed DDoS agent that orchestrates ICMP echo and TCP SYN flood attacks across zombie hosts, not a slow-session web application POST tool.

LOIC (Low Orbit Ion Cannon) is a volumetric DDoS tool that floods targets with high-rate UDP, TCP, or HTTP traffic, rather than exploiting session starvation through slow POST transmissions.

RUDY (R-U-Dead-Yet) exploits web server session handling by initiating HTTP POST requests with an arbitrarily large Content-Length value and then transmitting the request body one byte at a time at minimum speed, keeping server-side sessions open and unavailable to legitimate users. This session-starvation technique operates at the application layer without generating high traffic volume, making it difficult to detect via bandwidth thresholds. It directly matches the question description of starvation via never-ending POST transmissions and large Content-Length headers.

MyDoom is a mass-mailing computer worm that opens a backdoor and launches SYN-flood DDoS attacks against specific hosts; it does not perform slow-POST HTTP session starvation against web servers.
