Summary

Hide ▲

Apple’s iOS and iPadOS 26.4 Beta now tests end-to-end encryption (E2EE) for RCS messages, strengthening message confidentiality for Apple users. The same beta also expands Memory Integrity Enforcement (MIE) and is expected to bring Stolen Device Protection defaults, raising the bar against spyware, memory-corruption attacks, and device theft abuse. These changes matter because they move multiple security controls from optional or limited modes into broader platform coverage.

    Apple releases iOS and iPadOS 26.4 Beta

    Mitigation Patch Update

    Apple releases iOS and iPadOS 26.4 Beta with support for end-to-end encryption (E2EE) in Rich Communications Services (RCS) messages, limited to conversations between Apple devices and dependent on RCS Universal Profile 3.0 built atop the Messaging Layer Security (MLS) protocol. The same beta lets applications opt in to the full safeguards of Memory Integrity Enforcement (MIE) after earlier builds limited them to Soft Mode.

    iOS 26.4 is expected to default Stolen Device Protection

    Mitigation Patch Update

    iOS 26.4 is expected to enable Stolen Device Protection by default for iPhone users, adding Face ID or Touch ID checks for sensitive actions such as accessing stored passwords and credit cards when the device is away from familiar locations. The protection also adds a one-hour delay before Apple Account password changes so a stolen device can be marked as lost before account access changes take effect.
