Apple's iOS 27.2.1 fixes an iMessage bug that could let an attacker join a group chat, and Bluetooth and AirPlay flaws, so update now
If you have an iPhone, iPad or Mac, there is a security update waiting today that is worth installing before you do anything else.
Google DeepMind used AI to mathematically prove key guarantees of the Signal protocol, and found no new flaws
WIRED· 10 NovWIRED reports that Google DeepMind researchers used agentic AI, a framework called AlphaProof Code, to formally verify a number of the Signal protocol's key cryptographic guarantees, in a four-week proof-of-concept. The protocol protects messages on Signal, Google Messages and WhatsApp. The analysis found no new vulnerabilities in the portions of the protocol it covered, and it did not verify the whole Signal app.
- Nothing to do today: this is a check on the maths behind messaging encryption, not a new feature.
- Keep your messaging apps updated, since the apps around the protocol are where most real-world security problems turn up.
