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…

Stacheldraht is a distributed DDoS tool that coordinates ICMP and SYN flood attacks against network-layer targets, not an application-layer session starvation tool.

LOIC (Low Orbit Ion Cannon) is a volumetric flood tool that overwhelms targets with high-rate UDP, TCP, or HTTP traffic, not a slow-rate session exhaustion attack.

RUDY attacks web servers by opening multiple HTTP POST connections, declaring an arbitrarily large Content-Length header, and then transmitting the request body one byte at a time at a very slow rate. This keeps each server session occupied indefinitely, exhausting the session pool and preventing legitimate users from connecting - a classic slow-rate starvation attack rather than a volumetric flood.

MyDoom is a mass-mailing worm that spreads via email and installs backdoors; it is not a web session starvation tool.
