摘　　要：在对新型涉网犯罪的打击过程中,涉案网站的重建是取证的关键环节,而在实战中,网站的重建往往会遇到各种各样的问题,成为困扰基层刑事技术民警的技术瓶颈。如何能够快速、高效地重建涉案动态网站,成为公安刑事技术队伍面临的亟待解决的问题。本文所述的动态网站重建技术核心是把软件开发过程中的debug技术运用到刑事技术领域网站的重建和重构的过程中,快速找出网站重构过程中遇到的问题,定位到相关的源代码位置,从而通过修复或者更改源代码,跳过网站重建过程中遇到的障碍,快速高效地重建涉案动态网站。在网站程序运行到断点时,debug技术允许技术人员查看某些变量的值,包括全局变量及局部变量,能更快地掌握代码执行的逻辑和流程。该技术是计算机软件开发技术在公安刑事技术领域的创新性应用,能在实战中取得事半功倍的效果。For fi ghting against the network-related crimes,the re-entry/reconstruction of the involved websites is crucial to collect the evidence.In practice,it is found that almost every telecom-network fraud involves with the website-ecological server showing:in one case directly sending the victim the domain name of an investment website that allows the suspect to log in via the browser,or in other case having the mobile-phone-adapted apps encapsulated with the portal of the targeted website where to let the culprit enter by mobile devices,and/or any other tricking ways alike.Obviously,it is the server that stores the core background data of those fraud-involved websites.At present,the criminal investigators can generally analyze the entry domain name of the involved website,and/or obtain the website source code and relevant database through the network security department,yet are usually diffi cult to rebuild/re-enter the targeted website locally.The novel debug-relied stratagem enabling re-entry/reconstruction into the dynamic websites relating to network crimes can effectively solve the above problems.Such a stratagem described in this paper utilizes a variety of technologies comprehensively,placing its core at applying the debugging operation into modulating for reconstruction/re-entry of the targeted website so as to quickly fi nd out the problems encountered and locate the relevant source codes.Thus,some source codes can be repaired or changed to have the involved website rebuilt/re-entered when the technicians have solved the breakpoints at any position of related code,and/or explored the website program running about its correlating global and local variables to ascertain the specifi ed ones so that the logic and process of related code execution have been grasped clearly.For the technicians having the required knowledge and competence,they can master this debug-relied stratagem skillfully after short-term training and technical tutoring.In terms of applicable scenarios,this stratagem is adapted not only to the
