摘要:

COVID-19疫情重塑了全球对商品及服务的需求。突发公共卫生事件、经济困境和错误信息引发的恐慌将客户和供应商推向了影子经济。特别是,暗网市场(DWM),通过自由软件访问的商业网站,已经获得了极大的普及。在这里,我们分析了2020年1月1日至2020年11月16日期间从30个DWM中提取的851,199个列表。我们确定了788个与COVID-19产品直接相关的清单,并监测了产品类别的时间演变,包括个人防护设备(PPE),药品(例如,羟氯甲胆碱)和医疗欺诈。最后,我们比较了他们的时间演变趋势与公众注意力的变化,如Twitter帖子和维基百科页面访问量。我们揭示了在线影子经济在COVID-19大流行期间的演变,并强调了持续监测DWM的重要性,特别是现在真正的疫苗可用且供应短缺。我们预计,我们的分析将对致力于保护公众健康的研究人员和公共机构都感兴趣。

英文摘要:

The COVID-19 pandemic has reshaped the demand for goods and services worldwide. The combination of a public health emergency, economic distress, and misinformation-driven panic have pushed customers and vendors towards the shadow economy. In particular, dark web marketplaces (DWMs), commercial websites accessible via free software, have gained significant popularity. Here, we analyse 851,199 listings extracted from 30 DWMs between January 1, 2020 and November 16, 2020. We identify 788 listings directly related to COVID-19 products and monitor the temporal evolution of product categories including Personal Protective Equipment (PPE), medicines (e.g., hydroxyclorochine), and medical frauds. Finally, we compare trends in their temporal evolution with variations in public attention, as measured by Twitter posts and Wikipedia page visits. We reveal how the online shadow economy has evolved during the COVID-19 pandemic and highlight the importance of a continuous monitoring of DWMs, especially now that real vaccines are available and in short supply. We anticipate our analysis will be of interest both to researchers and public agencies focused on the protection of public health.
