Resemble AI ties Grok to 87 per cent of the deepfake files behind documented fraud attacks in H1 2026

What happened

Deepfake detection firm Resemble AI's H1 2026 threat report documented 821 verified deepfake attacks affecting at least 15,736 confirmed victims across roughly 3.46 million synthetic files in the first half of 2026, and said one tool, xAI's Grok, accounted for 87 per cent of every traceable file it could count. One in six of the attacks involved non-consensual sexual imagery of adults or children.

Resemble AI put verified direct financial losses across the tracked attacks at 6.95 million dollars, while estimating statutory civil exposure from the intimate-imagery cases alone at up to 2.24 billion dollars under US law. The figures are the company's own tally, released alongside a new detection model, rather than an independently audited count.
