Last night, Apple temporarily removed Telegram from the App Store because a single user had posted illegal pornographic content in a public chat group.
⬅️ Telegram was restored within a matter of hours. But I want to explain what happened, to warn other app developers and help protect online communities from similar attacks.
🧹Since Telegram quickly removes illegal content from public groups using all kinds of moderation tools, the attacker had to resort to a technical trick. They inserted AI-modified illegal content by editing an old message in an active chat group. As a result, the content was effectively hidden from group members, preventing them from seeing it and reporting it right away.
