A number of government-run sites were targeted during these attacks, including gerdab.ir, leader.ir, and president.ir. The Slowloris attack was chosen instead, because of its high impact and relatively low bandwidth. The belief was that flooding DDoS attacks would affect internet access for the government and protesters equally, due to the significant bandwidth they can consume. ( December 2009)ĭuring the protests that erupted in the wake of the 2009 Iranian presidential election, Slowloris arose as a prominent tool used to leverage DoS attacks against sites run by the Iranian government. For example, lighttpd and nginx do not succumb to this specific attack.
#Apache servers attacked by slowloris attack software
Administrators could also change the affected web server to software that is unaffected by this form of attack. Other mitigating techniques involve setting up reverse proxies, firewalls, load balancers or content switches. Since Apache 2.2.15, Apache ships the module mod_reqtimeout as the official solution supported by the developers.
#Apache servers attacked by slowloris attack mod
In the Apache web server, a number of modules can be used to limit the damage caused by the Slowloris attack the Apache modules mod_limitipconn, mod_qos, mod_evasive, mod security, mod_noloris, and mod_antiloris have all been suggested as means of reducing the likelihood of a successful Slowloris attack.
In general, these involve increasing the maximum number of clients the server will allow, limiting the number of connections a single IP address is allowed to make, imposing restrictions on the minimum transfer speed a connection is allowed to have, and restricting the length of time a client is allowed to stay connected. While there are no reliable configurations of the affected web servers that will prevent the Slowloris attack, there are ways to mitigate or reduce the impact of such an attack. In addition, certain servers are more resilient to the attack by way of their design, including Hiawatha, IIS, lighttpd, Cherokee, and Cisco CSS. Proxying servers and caching accelerators such as Varnish, nginx, and Squid have been recommended to mitigate this particular kind of attack. Verizon's Motorola Set-top box (port 8082 and requires auth - unconfirmed)īecause Slowloris exploits problems handling thousands of connections, the attack has less of an effect on servers that handle large numbers of connections well.Verizon's MI424-WR FIOS Cable modem (unconfirmed).Trapeze Wireless Web Portal (unconfirmed).This includes but is not necessarily limited to the following, per the attack's author:
