Web上第三方资源加载的研究

A Study of Third-party Resources Loading on Web

Muhammad Ikram, Rahat Masood, Gareth Tyson, Mohamed Ali Kaafar, Roya Ensafi

摘要:

本文对网络中的依赖链进行了大规模的研究,发现大约50%的第一方网站呈现的内容不是直接加载的。虽然大多数网站(84.91%)的依赖链较短(低于3级),但我们发现依赖链超过30的网站。使用VirusTotal,我们发现这些第三方中有1.2%被归类为可疑-虽然看起来很小,但这有限的可疑第三方对更广泛的生态系统有着显著的影响。我们发现,73%的网站从可疑的第三方加载资源,24.8%的第一方网页在其依赖链中包含至少三个被归类为可疑的第三方。通过运行沙箱实验,我们观察到一系列活动,其中大多数可疑的JavaScript代码下载恶意软件。

英文摘要:

This paper performs a large-scale study of dependency chains in the web, to find that around 50% of first-party websites render content that they did not directly load. Although the majority (84.91%) of websites have short dependency chains (below 3 levels), we find websites with dependency chains exceeding 30. Using VirusTotal, we show that 1.2% of these third-parties are classified as suspicious -- although seemingly small, this limited set of suspicious third-parties have remarkable reach into the wider ecosystem. We find that 73% of websites under-study load resources from suspicious third-parties, and 24.8% of first-party webpages contain at least three third-parties classified as suspicious in their dependency chain. By running sandboxed experiments, we observe a range of activities with the majority of suspicious JavaScript codes downloading malware.
