Last night Apple briefly removed Telegram from the AppStore because a user had planted illegal porn in a public chat. Telegram was restored within hours. But I want to explain what happened — to warn other app developers and help protect online communities from similar attacks. Because Telegram quickly removes illegal content from public groups using all kinds of moderation tools, the attacker had to resort to a technical trick. He inserted AI-modified illegal content by editing an old message in an active group chat. As a result the content was effectively hidden from the group’s members, preventing them from seeing/reporting it. The attacker was a takedown extortionist: someone who demands ransom from group owners in exchange for not targeting their communities. These extortionists use automated accounts to plant illegal content in public groups and then report it directly to Apple, attempting to trigger the removal of legitimate communities whose owners refused to pay them. From a practical standpoint, illegal pornographic content in Telegram’s public groups is not a systemic problem. Our moderation is effective. The fact that attackers must resort to backdated, effectively invisible content and other technical tricks proves this. ⚠️ However, there are two important lessons here for app developers and online communities: — Extortionists have found a way to manipulate Apple into overreacting. Apple removed Telegram from the App Store before contacting us. This creates a potential systemic risk for every mobile app that hosts user-generated content. If an app used by more than a billion people can be removed from the App Store without prior warning, any app can be. — The tactics used by takedown extortionists are evolving, putting communities across social platforms at risk. Telegram has extensive experience identifying the tricks used by coordinated reporting gangs and protecting legitimate communities (even when doing so risks our own app being temporarily removed from the App Store). Other platforms may not be equally prepared. Stay vigilant! ☝️

Only if education could be this interactive ❤️‍🔥 I've had a looong wish to build something genuinely useful through vibe coding, and I finally did it. A 3D human anatomy application built with @threejs using GPT 5.6 Sol. It all started with a single design image that I created using GPT Image 2.0. I then used it to generate every 3D organ image, one by one. Next, I converted each of those images into 3D models using @tripoai (and no, they didn't sponsor this 😄). After that, I opened Codex, wrote a master prompt based on the design, and gave it the prompt, the design image, and all the 3D models. Codex built the first version beautifully, but there was one big problem. Every single 3D model was nearly 120-150 MB. That obviously wasn't practical for the web and was giving a performance of 16fps. After a few iterations, Codex optimized each model down to roughly 2–5.5 MB while preserving the visual quality, reducing the total asset size from ~900 MB to just 28.6 MB. And each model loads on demand. Along the way, Codex also generated those anatomical illustrations showing where each organ sits in the human body, and even created the interactive hotspot markers that explain different parts of every organ. It handled all of that. The process wasn't exactly one shot, but it also wasn't difficult. You just have to do it step by step. It genuinely felt like building something that could make learning anatomy much more engaging. The inspiration came from @DilumSanjaya's 3D animal plant cell project. I remember seeing it and thinking, "I want to build something like this one day." And I did it :D Live: Code:

BREAKING: "We're building more auto factories and more plants than at any time in the history of our country." President Trump tells General Motors workers the American auto industry is surging, crediting the men and women on the factory floor for rebuilding the country. He also blasts past leaders for allowing manufacturing jobs to leave the U.S., saying his administration is putting Michigan workers and American industry first. "At long last, Michigan finally has a president who stands up for Michigan auto workers and puts America first."

"If you discovered all this in a suitcase, wouldn't you be this happy?" That's what Customs and Border Protection joked after K-9 Maisy sniffed out a suitcase arriving from Thailand packed with nearly 100 pounds of prohibited meat, plants and wildlife products. Officers say the luggage was stuffed with raw meat, mangoes, garlic, bamboo, banana plants and even a Bengal monitor lizard — a large, powerful reptile native to South and Southeast Asia that can grow more than five feet long. The lizard was turned over to the U.S. Fish and Wildlife Service. Officials say agriculture detector dogs like Maisy help stop invasive pests, animal diseases and illegal wildlife from entering the U.S.

“I hope you remember me, because what we've done is something that nobody thought was possible.” President Trump says new AI data centers will build their own power plants, calling it a major step that will expand U.S. AI infrastructure while helping lower electricity costs for consumers.

President Trump issued a warning that for every Iranian strike on a ship in the Strait of Hormuz, the U.S. will bomb and destroy one bridge or power plant inside Iran, including Tehran. @ABC News' @MarthaRaddatz has the latest.
