Abstract

Deepfakes, a form of artificial intelligence-generated content, represent a primary method for creating fake cybersecurity threat intelligence (CTI) and are a key source for data poisoning attacks. To effectively assess the authenticity of the cybersecurity threat intelligences (CTIs) in the open-source community, this study presents a novel algorithm for fake-CTI mining, aimed at identifying fake CTIs. Initially, we develop a generalized language model (GLM)-based system for fake CTI generation (GLM-based FCTIG) that adapts a public GLM to the cybersecurity domain using parameter-efficient fine-tuning. We then integrate these fabricated CTIs with authentic ones to simulate data poisoning attacks, evaluating the outcomes of data poisoning attacks from various perspectives. Additionally, we propose a hybrid classification model based on a fine-tuned BERT encoder and a TextCNN head (FCTICM-TC) to discern the authenticity of the CTIs. Finally, a comprehensive FCTICM-TC-based FCTIM method for mining the fake CTIs is presented. The experimental results demonstrate that the proposed GLM-based FCTIG scheme and FCTICM-TC model can effectively generate convincing fake CTI-like texts, while the FCTICM-TC-based FCTIM method is capable of identifying the fake CTIs efficiently.
