摘要：
在本研究中，我们更严格地评估了我们的攻击脚本TraceTarnish，该脚本利用对抗性风格学原理来匿名化文本消息的作者身份。为了确保攻击的有效性和实用性，我们收集、处理并分析了Reddit评论——这些评论后来被转化为TraceTarnish数据，以获得有价值的见解。转换后的TraceTarnish数据随后通过StyloMetrix进一步增强，生成风格学特征——这些特征通过信息增益标准筛选，仅保留最具信息量、预测性和判别性的特征。我们的结果发现，功能词和功能词类型（L_FUNC_A & L_FUNC_T）；内容词和内容词类型（L_CONT_A & L_CONT_T）；以及类型-词频比（ST_TYPE_TOKEN_RATIO_LEMMAS）产生了显著的信息增益读数。识别出的风格学线索——功能词频率、内容词分布和类型-词频比——作为可靠的入侵指标（IoCs），揭示了文本被人为篡改以掩盖真实作者的时间。同样，这些特征可以作为法医信号，提醒防御者存在对抗性风格学攻击；尽管在没有原始信息的情况下，这种信号可能被忽略，因为它似乎依赖于前后转换的比较。'在试图抹去痕迹时，你往往留下更大的痕迹。'基于这一理解，我们围绕这五个孤立特征框架了TraceTarnish的操作和输出，利用它们来概念化和实现增强，进一步加强攻击。
英文摘要：
In this study, we more rigorously evaluated our attack script $\textit{TraceTarnish}$, which leverages adversarial stylometry principles to anonymize the authorship of text-based messages. To ensure the efficacy and utility of our attack, we sourced, processed, and analyzed Reddit comments -- comments that were later alchemized into $\textit{TraceTarnish}$ data -- to gain valuable insights. The transformed $\textit{TraceTarnish}$ data was then further augmented by $\textit{StyloMetrix}$ to manufacture stylometric features -- features that were culled using the Information Gain criterion, leaving only the most informative, predictive, and discriminative ones. Our results found that function words and function word types ($L\_FUNC\_A$ $\&$ $L\_FUNC\_T$); content words and content word types ($L\_CONT\_A$ $\&$ $L\_CONT\_T$); and the Type-Token Ratio ($ST\_TYPE\_TOKEN\_RATIO\_LEMMAS$) yielded significant Information-Gain readings. The identified stylometric cues -- function-word frequencies, content-word distributions, and the Type-Token Ratio -- serve as reliable indicators of compromise (IoCs), revealing when a text has been deliberately altered to mask its true author. Similarly, these features could function as forensic beacons, alerting defenders to the presence of an adversarial stylometry attack; granted, in the absence of the original message, this signal may go largely unnoticed, as it appears to depend on a pre- and post-transformation comparison. "In trying to erase a trace, you often imprint a larger one." Armed with this understanding, we framed $\textit{TraceTarnish}$'s operations and outputs around these five isolated features, using them to conceptualize and implement enhancements that further strengthen the attack.
