Dataset Injection Scan — open study of popular HF datasets
from datasets import load_dataset
ds = load_dataset("fevziegeyurtsevenler/dataset-injection-scan-study")
Results of scanning 17,000 rows across 6 popular public instruction/prompt datasets for smuggled prompt-injection with hf-dataset-scan (invisible Unicode, injection phrasing EN+TR, exfil URLs).
Headline: no smuggled injection found

0 decoded Tags-block instructions · 0 bidi overrides · 0 genuine exfil URLs. All 26 low flags were benign on inspection (a prompts dataset naturally contains prompt-like phrasing; the rest were zero-width/BOM formatting). The invisible-injection threat to training data is real in theory but essentially absent in these corpora today — an honest, reproducible counter-hype baseline.
