iMessage

端到端加密是一种消息在发送方设备加密、只有接收方设备才能解密的通讯安全机制，服务提供商服务器无法读取内容

Signal and iMessage are among the few messaging platforms that truly implement end-to-end encryption.

Pegasus曾通过iMessage的零点击漏洞发起攻击

T3 Code's orchestration layer is implemented as a flexible MCP, allowing agents to communicate with each other, manage other threads, and be controlled remotely via external tools (such as an iMessage bot).

Kiwi is a proactive AI assistant that reaches out to users via text messages (iMessage and WhatsApp) rather than waiting for users to ask questions.

The strong presence of Apple's iMessage diminishes the appeal of RCS.

A zero-click exploit refers to an attack method that can remotely compromise a device without any interaction from the victim, typically exploiting message-parsing vulnerabilities in instant messaging services such as iMessage and WhatsApp.

Historically, Pegasus spyware has repeatedly exploited iMessage zero-click vulnerabilities to compromise the phones of journalists and political figures.

Tend's core positioning is a personal AI agent that requires no standalone app installation and is used via iMessage/SMS text messages.

iMessage is an encrypted communication protocol between Apple devices that transmits over the network and supports rich features such as read receipts and typing indicators; SMS is traditional telecom text messaging, which is cross-platform but limited in features and billed per message.

iMessage's end-to-end encryption does not cover third-party servers, so Tend needs to build its own message relay outside the Apple ecosystem, which involves compliance and privacy design.

Compared with plain-text SMS, RCS supports capabilities such as read receipts, typing indicators, high-definition images and videos, button-based quick replies and rich cards, with an experience close to iMessage.

Stella offers two ways to use it: voice conversation within the iOS app, or text communication with "Text Stella" via iMessage.

The iMessage channel, as a "parasitic entry point," must contend long-term with engineering and compliance issues such as multi-turn conversation context management, synchronization of voice and text session states, and distribution risks brought by platform policy changes.

Existing key transparency deployments (Signal, WhatsApp, iMessage) follow the Seamless family of approaches: the version number increments only when the public key changes, auditors verify each epoch whether the server follows the rules, and clients on return need only compare the first and last version numbers.

Traditional zero-click attacks mostly rely on unpatched remote code execution vulnerabilities in the operating system or browser (such as iMessage's FORCEDENTRY), whereas AdFection does not rely on a specific CVE and instead abuses browser API behaviors permitted by the advertising standard itself.

Commercial spyware such as Pegasus and Predator has used interaction-free exploit chains, delivered through instant messaging channels such as iMessage and WhatsApp, where the victim may be infected upon merely receiving a message.

The process of generating stickers in ChatGPT is: enter a descriptive prompt, generate the image, then save it and import it into the sticker feature of iMessage or WhatsApp, with no design skills or additional software required.

iMessage and WhatsApp are among the instant messaging platforms with the largest user bases in the world.

ChatGPT's image generation capabilities are being used by users to generate and share personalized stickers in iMessage and WhatsApp.
