Problems solved by technology

[0009] The honeypot-based system captures the botnet based on the built honeypot, passively waiting for the intrusion and control of the botnet, which has the disadvantages of not being able to respond to the botnet in real time and subsequent manual participation in analysis is heavy.

Embodiment Construction

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0031] In the botnet monitoring method in this embodiment, by deploying network detection equipment, firstly, packet feature detection is performed according to the rule base, and the communication packets between the controller and the IRC server, the IRC server and the zombie host are monitored, and the packets are discarded. , thereby blocking the communication of the botnet. Then, the monitoring table of controller bot and IRC server is established by the detection device, and subsequent behavior analysis and monitoring of the IRC botnet are performed to clearly detect the various roles of the IRC botnet such as the IRC server, the controller, and the botnet.

Abstract

The invention discloses a zombie network detection method and device. The zombie network detection method comprises the following steps of: carrying out zombie network characteristics detection and extracting zombie network information; monitoring behavior detection according to the zombie network information and storing the zombie network information in a monitoring form; scanning the monitoring form at regular time; and writing the zombie network information scanned in the monitoring form into a database to be written. The zombie network detection device is used for carrying out zombie network detection according to the zombie network detection method provided by the invention.

Description

technical field [0001] The present invention relates to computer networks, in particular to a method and device for detecting botnets. Background technique [0002] Botnet refers to a one-to-many controllable network formed between the controller and the infected host by infecting a large number of hosts with bot virus by one or more means of propagation. Attackers spread bots through various ways to infect a large number of hosts on the Internet, and the infected hosts will receive the attacker's instructions through a control channel to form a botnet. [0003] A botnet is a group of computers on the Internet that are centrally controlled by hackers, and are often used by hackers to launch large-scale network attacks, such as distributed denial of service attacks and massive spam attacks. It is a one-to-many control relationship, and the reason for this topology relationship enables an attacker to efficiently control a large number of resources to serve it at a very low co...
