SLOWLORIS ATTACK SCRIPT SOFTWARE

To write DDoS Attack script, The principle is to use socket Connect to the target site, And send a lot of http request, Thus depleting the resources of the attacked website пјљ.

blend пјљ The above two are mixed, That is, using the agreement гЂЃ Defects in the system, It also has massive resources, Such as SYN Flood attack ,DNS Query Flood attack.

Win by cleverness пјљ It is mainly initiated by taking advantage of loopholes in protocols or software, Such as Slowloris attack ,hash Conflict.

Win by force пјљ Massive data packets swarmed from all corners of the Internet, jam IDC entrance, Typical is ICMP Flood and UDP Floodпј€ Bandwidth consumption пј‰.

Two гЂЃDDoS classificationДЄs the most powerful гЂЃ One of the most difficult attacks to defend against ,DDos There are two main types of attacks. So it came into being DDoS attack, Its principle is very simple пјљ The processing power of computers and networks has increased 10 times, Attacking with an attacker no longer works, that DDoS It's using more puppet machines to launch attacks, Attack the victim on a larger scale than ever before. Single DoS Attacks are usually one-on-one, With the development of computer and network technology ,DoS The difficulty of the attack has increased. These connectionsВ haveВ the state SERVER_BUSY_WRITE.Python To write DDoS Attack script One гЂЃ What is? DDoS attackДDoS An attack is a distributed denial of service attack ,DDoS The means of attack are traditional DoS A kind of attack mode based on attack. However, there is a real problem with all approaches that look forВ SERVER_BUSY_READ: The attacker can just use a URL that accepts POSTВ requests and send the request body very slowly. However, as it turns out, the server actually switches to the SERVER_BUSY_WRITE state when receiving a POST, as described on the mailing lists: One would except SERVER_BUSY_READ to intercept these as well, as the server is, in fact, still reading a request from the client and waiting for it to complete. One might wonder which state actually protects against the slow post attack variant. You can disable mod_antiloris when using this module. Not surprisingly, the attack stopped working after installing this mod. Not much different compared to the previous mods, except that mod_limitipconn takes into account all possible server states. The extended version of the script can be found on Github.ДЇunction attack_get ( $ server, $ host ) Based on a PHP version of the original Slowloris attack ( found here), I wrote a modified script which also included the new POST-based attack method. Luckily, in this case, the attack isВ devilishlyВ simple. The first step in preventing and solving security problems lies in understanding the attack. I run Apache, so, naturally, I was (and still am) concerned about this attack vector. Also, recently, an alternative HTTP-based DOS method was found, using POST requests with a large content length ( article). Recently, the method was placed in the spotlights again, because both Wikileaks-supporters and non-supporters were using it to DOS a variety of websites and Wikileaks mirrors.

VerizonвЂ™s Motorola Set-Top Box (port 8082 and requires auth -В unconfirmed).

VerizonвЂ™s MI424- WR FIOS Cable modemВ (unconfirmed).

The attack is said to work on a large number of webservers, according to the project page: The serverвЂ™s connection pool gets filled and no other clients can be served. The attack is HTTP-based, and attacks webservers by making lots of keep-alive connections and keeping them alive by sending bogus HTTP headers. Affected servers will keep these connections open, filling their maximum concurrent connection pool, eventually denying additional connection attempts from clients. Periodically, it will send subsequent HTTP headers, adding to-but never completing-the request. It accomplishes this by opening connections to the target web server and sending a partial request.

SLOWLORIS ATTACK SCRIPT SOFTWARE

Slowloris is a piece of software written by Robert вЂњRSnakeвЂќ Hansen which allows a single machine to take down another machineвЂ™s web server with minimal bandwidth and side effects on unrelated services and ports.В Slowloris tries to keep many connections to the target web server open and hold them open as long as possible. If you are the least bit interested in network security, youвЂ™llВ undoubtedlyВ have heard about Slowloris byВ now. Slowloris And Mitigations ForВ Apache Introduction
