GlyphNet: Homoglyph Domains Dataset

Data for detecting homoglyph phishing domains (e.g. facebook.com spoofed with visually-similar Unicode characters). Every genuine domain is paired with a synthetically generated homoglyph variant, and each domain is also rendered to a 256x256 grayscale image so the task can be tackled as text or image classification.

Configs & splits

Both configs share the same train / validation / test split (70/20/10). Splits are assigned per pair (seeded), so a genuine domain and its homoglyph always fall in the same split - preventing leakage between near-identical pairs.

pair_id links the two images rows (one real, one phish) that came from the same source pair, and matches the pair_id in the pairs config.

from datasets import load_dataset

pairs  = load_dataset("Akshat4112/Glyphnet", "pairs")
images = load_dataset("Akshat4112/Glyphnet", "images")
train_img = images["train"]        # or "validation" / "test"

How it was generated

Homoglyphs are produced by substituting one or two characters with Unicode confusables (code/dataGeneration.py). Images are rendered with the DejaVu Sans font - Arial (used in the paper) is proprietary and not redistributed here, so glyph shapes may differ slightly from the original figures.

Intended uses & limitations

• —Intended for research on homoglyph / IDN-homograph phishing detection.
• —Homoglyphs are synthetic, not harvested from real attacks, so the distribution may not match live phishing in the wild.
• —The genuine and spoofed strings within a pair are near-identical; always respect the provided splits (or group by pair_id) to avoid leakage.
• —Rendering font differs from the paper (DejaVu Sans vs Arial).
