In this paper, we introduce the concept of social cyber forensics and its usability. Then, we introduce a tool, i.e., Maltego that can be used to study the cross-media affiliation and uncover hidden relations among various online groups. We also provide three stepwise methodologies that leverage Maltego and various open source information to uncover the hidden relationship among (1) Twitter accounts and a set of websites/blogs; (2) websites/blogs and other websites/blogs; or (3) infer the ownership of a set of websites/blogs. These methodologies have been tested during many cyber propaganda campaigns that were projected against NATO forces. A high-level view of these case studies that leveraged the concepts and methodologies provided in this paper are briefly highlighted here while the details of each case were published in various venues which are pointed out for interested readers.

在本文中，我们介绍了社交网络取证的概念及其可用性。然后，我们介绍一种工具，即Maltego，可用于研究跨媒体隶属关系并揭示各种在线群体之间的隐藏关系。我们还提供了三种逐步的方法，这些方法利用了Maltego和各种开源信息来揭示（1）Twitter帐户和一组网站/博客之间的隐藏关系；（2）网站/博客和其他网站/博客；或（3）推断一组网站/博客的所有权。这些方法在针对北约部队的许多网络宣传运动中得到了检验。
