Lookalike Domain Phishing Detection

The present disclosure enhances domain lookalike detection by integrating a phishing risk assessment score into a multi-layered evaluation framework. The method systematically generates lookalike domains through genetic algorithms. Registered domains undergo advanced phishing analysis, incorporating domain and URL checks, technical infrastructure assessments, content inspections, and reputation-based intelligence to calculate a dynamic phishing score. A comprehensive risk score is then determined by merging phishing likelihood with business attributes, graphical / contextual similarity metrics, and domain registration patterns. Domains are categorized into predefined risk levels including phishing, registered, preventative, company-owned, or watchlist, with specific action recommendations provided for each category. The system generates prioritized alerts for high-risk domains, offering customers actionable intelligence to mitigate threats. By combining phishing-specific indicators with contextual evaluations, this solution improves detection accuracy, reduces false positives, and enables organizations to respond effectively to domain-based threats in real time, addressing evolving cybersecurity challenges.

A method for protecting cue words in large models based on differential privacy

This application provides a method for protecting prompt words in large models based on differential privacy. By constructing a perturbation mapping table, differential privacy perturbation is applied only to the first token encountered in a multi-turn dialogue, and the mapping relationship is stored. Subsequent repeated tokens directly reuse the historical perturbation results, thus avoiding the accumulation of privacy budget with the increase of dialogue turns. Simultaneously, an attention-based context-aware utility function is combined to integrate the static embedding similarity of tokens with dynamic context similarity to maintain semantic consistency across turns. Finally, a two-stage bucketing index mechanism is adopted, first bucketing candidate tokens according to utility, and then fine-sampling within the selected buckets, effectively mitigating the long-tail effect under large vocabulary and improving the stability of perturbation selection. This application achieves a balance between privacy protection strength and semantic usability in multi-turn dialogues, and only requires perturbing the input prompt words without accessing the model's internal architecture, making it suitable for black-box large language model inference scenarios.
