LLM-Based Adversarial Persuasion Attacks on Fact-Checking Systems
This report details the critical vulnerabilities of Automated Fact-Checking (AFC) systems to sophisticated persuasion techniques, revealing how LLMs can be weaponized to generate highly deceptive disinformation. Our analysis, based on the latest research from the University of Sheffield, demonstrates a need for more robust AFC defense mechanisms in an era of advanced AI manipulation.

The Novel Threat of Persuasion Injection Attacks
This research introduces a novel class of persuasive adversarial attacks against Automated Fact-Checking (AFC) systems. Unlike traditional methods that rely on noise or semantic alterations, these attacks weaponize generative LLMs to rephrase claims using sophisticated persuasion techniques. This allows false claims to evade detection while appearing fluent and rhetorically optimized.
Understanding these new attack vectors is crucial for developing resilient defense mechanisms in an increasingly complex disinformation landscape.
AFC System Susceptibility
Our findings reveal that persuasion injection attacks significantly degrade both verification performance and evidence retrieval in AFC pipelines. Accuracy can drop by more than twice as much compared to previously studied adversarial attacks like synonym substitution. Under an optimized "Oracle" attacker, accuracy collapses to near-zero, even when gold-standard evidence is provided.
This demonstrates a profound vulnerability, highlighting that current AFC systems struggle to disentangle persuasive rhetoric from factual content, leading to misclassification and pipeline failures.
Manipulative Wording: The Most Damaging Category
Techniques within the Manipulative Wording category, particularly Obfuscation, emerge as the most damaging. These techniques remove concrete information and introduce ambiguity, making it harder for evidence to explicitly contradict claims. This simultaneously degrades both evidence retrieval and classification performance.
For example, replacing "50 days" with "approximately one and a half months" in a claim can lead to high evasion rates, as the vagueness confuses both retrievers and classifiers, preventing accurate verification.
