Abstract

The embodiment of the invention discloses a method and device for extracting a message format. The method is characterized by comprising the following steps of capturing an execution trace of a rogue program client; analyzing the input message processing process in the execution trace, and extracting the input message format of the rogue program communication protocol. According to the method, the execution trace of the rogue program client is analyzed, the automatic extraction of the input message format of the rogue program communication protocol can be realized without depending on the manual operation of people, the automation degree can be improved, the dependence on the human experience can be reduced, the manpower cost is reduced, and the extraction efficiency can be improved; the semantic information of the system level can be provided by analyzing the execution trace of the rogue program client, analysis on the fine-grained rogue code can be realized, the accuracy in analysis and location can be achieved, and the false alarm rate can be reduced.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and device for extracting message formats. Background technique [0002] The malicious program referred to in the embodiment of the present invention refers to a malicious program implanted into a device (for example, a computer) so that the device can be controlled by a remote input message. Such malicious programs usually define a communication protocol, and when the malicious program client receives a message from the control terminal, it will respond accordingly. Its typical representative is the client program of the botnet. A botnet refers to a network composed of user computers controlled by attackers through bot programs, and its basic feature is to use a one-to-many command and control mechanism. Since IRC (Internet Relay Chat Protocol, Internet Relay Chat Protocol) provides a simple, low-latency, anonymous real-time communication method, and is a...
