Sunbird, iMessage client for Android, shuts down amidst security concerns

Sunbird had made a name for itself as being a pioneering service that sought to bring iMessage to Android, attracting users with its user-friendly interface and unique features. However, the app’s trajectory took a sharp turn, and recently announced that it’s shutting down its app due to serious security concerns. (via. 9to5Google)

Investigations revealed that Sunbird app has fundamental security flaws, including the transmission of unencrypted user data. This exposed users’ sensitive information to the risk of interception and unauthorized access.

Sunbird failed to implement end-to-end encryption. This means that user data, including messages, media files, and potentially even personal details, were transmitted in an unencrypted format. This made it relatively easy for other users to access this data by intercepting it or gaining access to the Sunbird servers. Over 630,000 files were accessible through this vulnerability.

Thread time!

Summary:
– Sunbird has access to every message sent and received through the app on your device.

– All of the documents (images, videos, audios, pdfs, vCards…) sent through Nothing Chat AND Sunbird are public.

– Nothing Chats is not end-to-end encrypted.

Nothing, the company founded by OnePlus co-founder Carl Pei, has collaborated with Sunbird to launch its own new messaging app. This collaboration resulted in the introduction of Nothing Chats, a messaging app designed to bring iMessage functionality to the Nothing Phone (2). The app was in beta testing, and was already supporting many iMessage features, including group chats, live typing indicators, and full-resolution media sharing. The app was expected to be released to the public on November 17. However, the app’s launch was met with immediate backlash due to glaring security vulnerabilities.

In light of these critical security concerns, Nothing also made the decision to shut down its app, at least for now. Until they work with Sunbird to fix the major issues. While this decision was disappointing for users who had looked forward to the app’s potential, it was a necessary step to protect user privacy and prevent further data breaches.

We've removed the Nothing Chats beta from the Play Store and will be delaying the launch until further notice to work with Sunbird to fix several bugs.

We apologise for the delay and will do right by our users.

The Sunbird saga serves as a cautionary tale for the messaging app industry, highlighting the importance of prioritizing user privacy and implementing robust security measures. It is a stark reminder that app developers must take user data protection seriously and ensure that their platforms are not conduits for cyberattacks and data leaks.

Meanwhile, Apple’s decision to adopt RCS is a significant development that will improve the messaging experience for both iPhone and Android users. RCS is a modern messaging standard that supports features like high-quality media sharing, read receipts, and typing indicators. With RCS, iPhone and Android users will be able to enjoy a more seamless and consistent messaging experience.

The adoption of RCS by Apple is also likely to reduce the need for workaround iMessage clients on Android. These clients, such as Nothing Chats, Sunbird, and Beeper have been developed to provide iMessage-like messaging features to Android users. However, with RCS, Android users will be able to get these features without the need for any third-party app.
