Pyloris is a slow HTTP DoS tool which enables the
attacker to craft its own HTTP request headers. These include the packet
header, cookies, packet size, timeout and CRLF option.
Pyloris objective
is to keep TCP connections open for as long as possible between the attacker and
the victims servers. This results in exhausting the server's connection table
resources. Once the connection table of the server is exhausted, it will not be
able to handle new connections from legitimate users, resulting in a
denial-of-service.
