iPhone AI app leaked 55,000 NSFW user stories – and emails too
April 2025 by CyberNews
What happens in your AI-generated erotica app… apparently doesn’t stay there.
Cybernews researchers discovered that Novel AI: Book Creator – an iOS app with nearly 2,000 App Store reviews – exposed over 55,000 user-generated stories, some of them heavily NSFW, along with customer support emails and personal data via a misconfigured Firebase database.
Why it matters:
• Blackmail bait: exposed stories + email addresses = a sextortion goldmine
• Hardcoded secrets: the app also leaks keys, tokens, and IDs that could give attackers backend access
• Silent devs: the developers have yet to respond, even months after disclosure
• Systemic problem: 71% of the 156,000 iOS apps we analysed leak at least one secret
“When adult content gets leaked, it’s more than a privacy issue – it’s a weapon for threat actors,” says Aras Nazarovas, lead researcher behind this research.
This is part of a much broader issue: our team analyzed 156,080 randomly selected iOS apps (around 8% of the App Store) and found that 71% expose sensitive data.
