iPhone's Green Bubble Chats Remain Vulnerable to Significant Security Concerns

RCS on iPhone: What's Up with the Lack of Encryption?
It's about half a year since Apple decided to go bold with iOS 18's RCS support, bringing a breath of fresh air to the iPhone. By saying goodbye to SMS, RCS has given us better group chats and higher quality video sending. Yet, one significant issue remains unaddressed - the lack of encryption for RCS messages on iPhone.
Diving into the RCS Basics
To set the scene, let's define RCS: Rich Communication Services, a beefed-up version of SMS, supports modern messaging features, such as typing bubbles, top-notch image and video sharing, manageable group chats, and secure end-to-end encryption. SMS misses those transport, but dissatisfaction sets in when using it, especially in group situations.
RCS isn't available across the board on Android messaging services, but if both parties support it (Android and iPhone), your talks should feel quite similar to iMessage exchanges between iPhones (minus the blue bubbles). Most features are working fine: you can monitor typing status, send crisp photos and videos, and enjoy group chats that perform much like those on iPhones. Nevertheless, one significant issue persists.
The Missing Encryption Piece on iOS
Currently, RCS messages between iPhones and Androids aren't end-to-end encrypted. This omission leaves communication between iPhone users and Android enthusiasts in a vulnerable state, since messages aren't safeguarded by modern security measures.
For iPhone users, this isn't entirely out of the ordinary: SMS chats with Android users were similarly unprotected. But the allure of RCS on iPhone promised encrypted messaging. When you notice the RCS tag in your chat's green bubble, you'd expect your confidential conversations to be secure, with no third parties snooping in.
RCS: Encrypted Everywhere but Here
It's worth noting that RCS encryption is a work in progress for all platforms. Google Messages is the heavyweight adopting default end-to-end encryption through RCS, yet if the other user isn't on Google Messages with RCS enabled, your messages may remain unencrypted. Other popular platforms, like Samsung Messages or Textra, don't even support end-to-end encryption.
Brighter Days Ahead: Encryption Arrives on iOS
The good news is that understanding is growing, and the future is encrypted. The GSMA, the organization behind mobile operator standards, has revealed new RCS specifications based on the Messaging Layer Security (MLS) protocol, ensuring that all RCS messages on every platform will be end-to-end encrypted. This upgrade may not be a shocker, as the GSMA has publicly stated they're working on end-to-end encryption for RCS on iPhone - no exact release date is available yet, but both Apple and Google are eager to speed up adoption.
Although this doesn't alter the fact that RCS messages on iPhone are currently unencrypted, it does highlight the promise of a safer future for communication. In the meantime, for those who yearn for all conversations with non-iPhone friends to remain protected, you're best off sticking to alternative secured messaging platforms, such as Signal or WhatsApp. iMessage, in its native form, is securely encrypted already, so no worries there.
Android Users: Group Chat Names Revealed
For Android users accustomed to the ways of Google Messages, listen up: Group chat names are publicly accessible when messaging with iPhones.
On Google Messages, renaming a group is all yours, with only you seeing the new title. This makes tackling specific groups easier, without worrying that others in the group will know how you've categorized the chat. Despite this, iPhones users have the upper hand here: they can see that group chat names are subject to change by every member in the group, with every modification visible to all.
So, if you're new to RCS chats with iPhone users, avoid renaming the group to anything you wouldn't want everyone in the group to see.
- Despite the encryption promise with RCS on iPhone, current RCS messages between iPhones and Androids lack end-to-end encryption, leaving communication vulnerable to third-party snooping.
- The GSMA, responsible for mobile operator standards, has unveiled new RCS specifications based on the Messaging Layer Security (MLS) protocol, aiming for end-to-end encryption of all RCS messages across all platforms.
- In the future, both Apple and Google are working on adopting end-to-end encryption for RCS on iPhone, promising a safer communication environment for all RCS users.
