SlowMist: Crypto users are advised to upgrade to Apple's latest iOS 27.2.1 system, which fixes multiple security vulnerabilities.

November 10: SlowMist CISO 23pds posted on social media that Apple's iOS 27.2.1, iPadOS 27.2.1, and macOS 27.2.1 updates released today fix multiple security vulnerabilities (details below), and users are advised to update as soon as possible:

· iMessage vulnerability: Remote attackers may join group chats to receive messages, or users may see messages from before they joined.

· AirPlay and Bluetooth vulnerabilities: Malicious Bluetooth devices may pair without interaction; nearby attackers may corrupt process memory; multiple vulnerabilities can bypass the AirPlay pairing code attempt rate limit.

· eMudhra certificate vulnerability: Adds protection for command-line tools.

23pds advises users to upgrade as much as possible to ensure security: "The latest 27.2.1 version can prevent DarkSword attacks, block the memory corruption issue caused by CVE-2026-112611 when processing malicious PDFs, and also stop the worse_query sandbox escape issue."
