走出阴影：分析匿名者在2020年黑人生命问题抗议活动中的Twitter复兴
Out of the Shadows: Analyzing Anonymous' Twitter Resurgence during the 2020 Black Lives Matter Protests
摘要：
最近，曾经著名的黑客组织“匿名者”几乎没有什么值得注意的活动。该组织负责对主要企业和政府进行基于活动家的网络攻击，在2013年主要成员被捕后，该组织似乎已经分裂。然而，在回应乔治·弗洛伊德被杀后发生的主要黑人生命物质（BLM）抗议活动时，有报道称该组织又回来了。为了研究这种明显的复苏，我们对Twitter上的匿名子公司进行了大规模的研究。为此，我们首先使用机器学习来识别一个由33,000多个匿名账户组成的重要网络。通过从这些账户收集的推文的主题建模，我们发现了对BLM相关主题持续感兴趣的证据。然后，我们使用情感分析的推文集中在这些主题，发现一个团结的方法之间的组，积极的推文通常被用来表达对BLM的支持，和负面的推文通常被用来批评警方的行动的证据。最后，我们检查了网络中自动化的存在，确定了大多数匿名帐户中类似机器人行为的迹象。这些调查结果表明，虽然该组织在抗议活动中出现了复苏，但机器人活动可能是夸大这种复苏程度的原因。
英文摘要：
Recently, there had been little notable activity from the once prominent hacktivist group, Anonymous. The group, responsible for activist-based cyber attacks on major businesses and governments, appeared to have fragmented after key members were arrested in 2013. In response to the major Black Lives Matter (BLM) protests that occurred after the killing of George Floyd, however, reports indicated that the group was back. To examine this apparent resurgence, we conduct a large-scale study of Anonymous affiliates on Twitter. To this end, we first use machine learning to identify a significant network of more than 33,000 Anonymous accounts. Through topic modelling of tweets collected from these accounts, we find evidence of sustained interest in topics related to BLM. We then use sentiment analysis on tweets focused on these topics, finding evidence of a united approach amongst the group, with positive tweets typically being used to express support towards BLM, and negative tweets typically being used to criticize police actions. Finally, we examine the presence of automation in the network, identifying indications of bot-like behavior across the majority of Anonymous accounts. These findings show that whilst the group has seen a resurgence during the protests, bot activity may be responsible for exaggerating the extent of this resurgence.
