Abstract

Due to the onset of the Covid-19 pandemic, people are compelled to maintain social distance in all spheres of life, forcing people to adopt virtual mode of activity. Usage of social media and other internet activity has shot up in this period, and consequently, cybercrimes have also increased. If cybercrimes are reported, computer forensics analysts will examine the concerned website, online forum, or social media to find meticulous details about the cybercrime. But webpage content seen on the day may not be available on the next day. The contents of the webpage, which is the subject of crime, will be deleted or withdrawn, or deactivated to destroy evidence to escape from legal proceedings. The victims usually produce a screenshot of the webpage or image or video as a piece of evidence. But there is a distinct possibility of manipulating the offensive materials and it may not be considered a valid piece of evidence before the court of law. Such a scenario requires a forensic technique that should acquire the content of the webpage before it is removed from web site to maintain the authenticity of captured data. So, we are proposing an automated system for the forensic acquisition of a website that will effectively capture all content from the live website and make it useful for forensic investigation and may be produced before the court as valid evidence of cybercrime.
网页的取证采集与分析
由于新冠肺炎大流行的爆发,人们被迫在生活的各个领域保持社交距离,迫使人们采取虚拟的活动方式。在此期间,社交媒体和其他互联网活动的使用急剧增加,因此,网络犯罪也有所增加。如果报告了网络犯罪,计算机取证分析人员将检查有关网站、在线论坛或社交媒体,以找到有关网络犯罪的详细信息。但是当天看到的网页内容第二天可能就看不到了。作为犯罪主体的网页内容,将被删除、撤回或停用,以销毁证据逃避法律诉讼。受害者通常会提供网页截图或图片、视频作为证据。但显然存在操纵这些攻击性材料的可能性,而且在法庭上,这可能不会被视为有效的证据。这种情况需要一种取证技术,该技术应该在网页从网站上删除之前获取网页内容,以保持捕获数据的真实性。因此,我们提出了一个自动化的系统,用于法医采集一个网站,该网站将有效地捕获现场网站的所有内容,并使其对法医调查有用,并可能在法庭上作为网络犯罪的有效证据。
