GoPlus Security Notice

We are sharing an important update regarding your device safety. During the Hexacon 2026 conference, security researchers demonstrated four vulnerabilities impacting Apple iOS, iPadOS, and macOS. You can find the technical breakdown of these findings at https://blog.calif.io/p/iphone.

This particular issue involves a one-click exploit that appears to be connected to the CoreGraphics vulnerability identified as CVE-2026-86950. By simply opening a maliciously crafted PDF document within Signal or iMessage, unauthorized code can be executed on your device. Consequently, this could allow attackers to extract your local messages and transmit them to a remote server.

The following operating systems are currently vulnerable to this threat:
iOS and iPadOS versions prior to 26.7.1
macOS Tahoe versions earlier than 26.7.1
macOS Sequoia versions older than 15.8.1

To address these security flaws, Apple issued emergency updates 26.7.1 and 15.8.1 on Sept 28. You can review the official patch details directly at https://support.apple.com/en-us/149226.

Please exercise caution and do not open any suspicious PDF files. We strongly advise you to update your iPhone, iPad, and Mac immediately, and to always ensure your devices remain on the latest operating system to maintain your security.
