AI-POWERED CYBERSECURITY BREAKTHROUGH
Revolutionizing Phishing Email Detection with E-PhishGen
Despite near-perfect accuracy claims in research, phishing remains an "unsolved dilemma" in the real world. E-PhishGen critically assesses existing methods, identifies core issues with outdated, monolingual datasets, and introduces a novel framework for generating high-quality, multilingual phishing email benchmarks, paving the way for truly effective detection.

The Dataset Dilemma: Why Research Falls Short
Our analysis of existing benchmark datasets reveals critical shortcomings: (a) reliance on old (pre-2010) and monolingual (English) emails, (b) frequent mixing of 'phishing' and 'spam' labels, and (c) a pervasive lack of publicly available source code, hindering reproducibility and progress. These factors lead to misleading 'near-perfect' accuracy claims that do not reflect real-world phishing trends.
Reassessing Detector Performance: The Generalization Gap
We re-evaluated various ML-based phishing detectors (feature-based, feature-agnostic, LLM-based) on existing benchmarks. While models show near-perfect performance when trained and tested on the same dataset, their performance drops significantly in cross-evaluation scenarios. Zero-shot LLMs perform strongly, indicating potential but also highlighting the inadequacy of current benchmarks to test generalizability.
Introducing E-PhishGen: A Framework for Realistic Benchmarks
To overcome dataset limitations and privacy concerns, we propose E-PhishGEN, an LLM-based framework to automatically generate tailored, high-quality phishing email datasets. It creates synthetic company and user profiles, then crafts both benign and malicious emails that reflect current attack vectors, are multilingual, and avoid personal data.
E-PhishLLM: Performance Insights on the New Benchmark
Testing existing detectors on our newly generated E-PhishLLM dataset (English subset, 11502 emails) revealed a significant performance drop compared to traditional benchmarks. F1-scores for ML models ranged from 0 to 0.73, indicating a more challenging and realistic benchmark. LLMs, however, demonstrated robust detection with F1-scores up to 0.95 (claude-3.5-haiku), suggesting their advanced capabilities.
Validating E-PhishLLM Quality: A User Study
A user study with 30 cybersecurity experts validated E-PhishLLM's superior quality. Participants rated E-PhishLLM emails as significantly more convincing, well-written, and realistic (average 3.41/5) compared to emails from SpamAssassin (1.57), Enron (1.45), and Nazario (2.65), confirming its effectiveness as a modern, challenging benchmark.

| Feature | Legacy Datasets (e.g., SpamAssassin, Enron) | E-PhishLLM |
|---|---|---|
| Data Age | Pre-2010 | 2025 (LLM Generated) |
| Languages | Predominantly English | English, Italian, German |
| Phishing Quality | Often mixed with spam, outdated styles | High-quality, context-aware, LLM-written |

The Phishing Dilemma: Research vs. Reality
For years, academic research has claimed near-perfect accuracy in phishing email detection, yet real-world organizations continue to be flooded with successful attacks. This stark contradiction highlights a critical 'open problem'. Our work exposes the root cause: reliance on outdated, unrepresentative benchmark datasets that fail to mirror the sophistication of modern phishing tactics. E-PhishGen confronts this by providing tools to generate challenging and realistic test data, finally aligning research efforts with practical cybersecurity needs.
