隐藏在众目睽睽之下：对儿童接触YouTube上恶意网址的测量和分析
Hiding in Plain Sight: A Measurement and Analysis of Kids' Exposure to Malicious URLs on YouTube
摘要：
互联网已成为儿童和青少年日常生活的重要组成部分。社交媒体平台每天被年轻用户用作教育和娱乐资源，这导致他们在与各种社交媒体平台互动时做出巨大努力以确保他们的安全。在本文中，我们调查了这些用户在针对这一人群的YouTube视频上发布的评论中暴露于不适当和恶意内容的情况。我们收集了大约400万条记录的大规模数据集，并研究了这些视频上发布的评论中嵌入的恶意和不适当URL的存在。我们的研究结果显示，在儿童和青少年用户的评论中嵌入了大量恶意和不适当的URL。特别是，我们观察到数量惊人的不适当和恶意URL，儿童接触的机会很高，因为包含此类URL的视频的平均观看次数为4800万。在使用这些平台时，儿童不仅接触到平台上提供的材料，而且还接触到评论中嵌入的URL的内容。这突出了监控评论中提供的URL的重要性，限制了儿童接触不适当内容的机会。
英文摘要：
The Internet has become an essential part of children's and adolescents' daily life. Social media platforms are used as educational and entertainment resources on daily bases by young users, leading enormous efforts to ensure their safety when interacting with various social media platforms. In this paper, we investigate the exposure of those users to inappropriate and malicious content in comments posted on YouTube videos targeting this demographic. We collected a large-scale dataset of approximately four million records, and studied the presence of malicious and inappropriate URLs embedded in the comments posted on these videos. Our results show a worrisome number of malicious and inappropriate URLs embedded in comments available for children and young users. In particular, we observe an alarming number of inappropriate and malicious URLs, with a high chance of kids exposure, since the average number of views on videos containing such URLs is 48 million. When using such platforms, children are not only exposed to the material available in the platform, but also to the content of the URLs embedded within the comments. This highlights the importance of monitoring the URLs provided within the comments, limiting the children's exposure to inappropriate content.
