System and method for treating computer worms

Abstract

The invention provides a system and a method for treating computer worms. The system comprises an infection character string receiving module, a treatment character string generation module and a treatment character string back-transmission module, wherein the infection character string receiving module receives an infection character string generated by the computer worms from a host computer infected by the computer worms, wherein the infection character string comprises a malicious code executed by utilizing a bug program; the treatment character string generation module generates a treatment code used for treating the computer worms, and replaces the malicious code of the infection character string with the treatment code to generate a treatment character string, wherein the treatment code is executed by utilizing the bug program; and treatment character string back-transmission module transmits the treatment character string back to the infected host computer. Therefore, the bug program of the infected host computer executes the treatment code to treat the computer worms in the infected host computer.

Description

technical field [0001] The present invention relates to a computer worm treatment system and method and a computer-readable recording medium storing the computer worm treatment method. Background technique [0002] A computer worm, like a computer virus, is a computer program that replicates itself. Among them, computer worms do not need to be attached to other programs, and usually do not require user intervention to perform self-replication or execution. Not all computer worms directly damage the infected system, but most are harmful to the network. In addition, computer worms may execute junk program codes to launch a Denial-of-Service (DOS) attack, or greatly reduce the execution efficiency of the computer, thereby affecting the normal use of the computer. [0003] The primary distribution vector for computer worms is buffer overflow vulnerabilities. In recent years, with the development of relevant protection measures, it has indeed increased the difficulty of worm p...

Problems solved by technology

[0004] Therefore, computer worms are still a serious threat to the security of the Internet, and attackers will greatly increase the concealment of the spread and existence of worms and malicious programs in consideration of commercial interests, so as to prolong the time of their impact

However, prior technologies can only treat computer worms that already exist on the machine, and cannot suppress the spread of computer worms
