Telegram claims to have suffered from "de-listing extortion" attacks: the temporary removal of the app from the Apple App Store was caused by a user embedding prohibited content

Telegram founder and CEO Pavel Durov stated that Telegram was briefly removed from the App Store by Apple recently due to a user embedding illegal pornographic content in a public group. The app was restored within hours.Durov mentioned that the attackers exploited a technical vulnerability to insert AI-modified illegal content into old messages in active groups, hiding the content by editing historical messages, making it difficult for regular group members to discover and report it in a timely manner. Such attacks are classified as "takedown extortion," where attackers use automated accounts to embed violations in public groups and report them to platforms like Apple, attempting to force group administrators to pay a ransom, or else the community would be banned due to platform rules.Durov further explained that Telegram continuously combats illegal content through user reports, AI filtering, content hashing, and other mechanisms. This incident is not a systemic issue of the platform but rather a targeted attack exploiting rule loopholes by the attackers.He also warned that Apple's direct removal of the app without prior contact with Telegram could pose risks to all mobile applications that provide user-generated content (UGC), and platform developers need to enhance their defenses against malicious reporting and "takedown attacks."

OpenAI issued a public statement on August 3 in response to the lawsuit filed by Apple. OpenAI described Apple's lawsuit as "careless, aggressive, and personal," and pointed out several factual inaccuracies: an external lawyer from Apple mistakenly sent an email intended for someone else to OpenAI's legal head, falsely claiming that the two parties had spoken over the phone; Apple later admitted it was due to "confusing two Asian surnames." OpenAI also revealed that after contacting Apple in February, Apple stated it was "working to resolve any issues," but then did not communicate for 5 months until filing the lawsuit.Regarding the allegations against former Apple employee Chang Liu for taking confidential information, OpenAI presented iMessage records from after his departure showing that Apple colleagues had proactively contacted him to request assistance in locating documents, and acknowledged that this was a common issue caused by Apple's "poor management of exit access." Another named executive, Tang Tan, had worked at Apple for over 24 years, and OpenAI stated that he had consistently required his team "not to use any confidential information from other companies." OpenAI indicated that it had proactively offered to cooperate in resolving the matter, but Apple chose to file a lawsuit, claiming that its request for a preliminary injunction was "based on false information and completely unnecessary." Previously, Apple sued OpenAI in July, accusing it of poaching Apple employees and using confidential information to develop AI products.
