A researcher has unleashed a free denial-of-service (DoS) hacking tool 
for flooding TCP sessions.

Called LetDown, the penetration testing tool is part of a larger package 
of tools called Complemento that was created by Italian researcher Acri 
Emanuele. "Complemento is a collection of tools that I originally 
grokked up for my personal toolchain for solving some problems or just 
for fun," Emanuele wrote in his post announcing the availability of the 
tools. He also admits having concerns about releasing LetDown to the 
public.

"I had some doubts, because with this tool [it] is possible to crash a 
server configured in the wrong way using very slow connections, without 
the need of botnets. A great fun for script kiddies," Emanuele told Dark 
Reading.

"Basically, LetDown is a TCP flooder that completes the three-way 
handshake and sends a requests to the server without closing the 
connection," he said. "LetDown is aimed specifically at pen testers and 
server owners that want to test the resiliency of their networks against 
DoS attacks in order to properly configure the rules on resource 
management on their systems."
