One AI made 87% of the deepfake attack files that hurt real people in the last six months. Nearly 16,000 victims.
Tech Times covered the new H1 2026 Deepfake Threat Report from cybersecurity firm Resemble AI, and the numbers are stark:
The Concentration
Grok AI was responsible for 87% of the synthetic files linked to documented deepfake attacks in the first half of 2026 -- a scale-concentration finding with no precedent in prior editions of the report.
The Scale
Across 821 separate attacks affecting at least 15,736 confirmed victims, researchers counted approximately 3.46 million synthetic images, videos, and audio files -- nearly enough to match all of 2025's total media reach, in half the time.
The Human Cost
One in six of the documented attacks -- 137 of 821 -- involved non-consensual intimate imagery of adults or children.
The Financial Exposure
Resemble AI estimates companies permitting or distributing the documented images could face as much as $2.24 billion in potential civil liability under US law.
The Caveat
The report notes the 87% figure only covers files researchers could actually trace to a specific tool -- meaning the real scale is likely larger, since unreported attacks aren't captured at all.
