Problems solved by technology

[0005] However, since active defense is more likely to generate more false positives than traditional signature database matching and killing, the level of active defense against all program behaviors should not be too high
Moreover, if a high-level active defense is carried out against the behavior of all programs, the efficiency of active defense will also be reduced.
However, if the general level of active defense is low, it will allow some malicious programs to take advantage of it. Therefore, the effectiveness of the existing active defense is low

Abstract

The method discloses a method, a device and a system for actively defending against malicious programs. The method includes monitoring the process creating operation of an unknown program to obtain a command line parameter under the execution of the created process; analyzing the command line parameter of the created process, and determining whether the created process is an uncompressing process at least according to the command line parameter under the execution of the created process; and if so, informing a drive program to record information generated by the uncompressing process to a first database and performing active defense monitoring on the information generated by the uncompressing process. The invention also discloses a device and a system for defending against the malicious programs.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a method, device and system for active defense against malicious programs. Background technique [0002] With the widespread use of computer technology in various fields of social life, malicious programs are also coming one after another like its appendages. Due to the infectiousness, replicability and destructiveness of these malicious programs, they have become a major problem plaguing computer use. [0003] Malicious program is an umbrella term for any software program intentionally created to perform unauthorized and often harmful acts. Computer viruses, backdoor programs, keyloggers, password stealers, Word and Excel macro viruses, boot sector viruses, script viruses (batch, windowsshell, java, etc.), Trojan horses, crimeware, spyware and adware, etc., are all are some examples of what could be called malicious programs. Take the Trojan horse as an example. The...
