While we build robust technical safeguards, user vigilance is ultimately the best defense against phishing. We will continue to work on mitigating these risks via interface design and signposting throughout the app. 6/7
We also want to emphasize that Signal Support will *never* initiate contact via in-app messages, SMS, or social media to ask for your verification code or PIN. If anyone asks for any Signal related code, it is a scam. We make this clear when users receive their SMS code during initial signup. 5/7
To help prevent this, remember that your Signal SMS verification code is only ever needed when you are first signing up for the Signal app. To protect people from such phishing, Signal actively warns users against sharing their SMS code and PIN. 4/7
These attacks, like all phishing, rely on social engineering. Attackers impersonate trusted contacts or services (such as the non-existent “Signal Support Bot”) to trick victims into handing over their login credentials or other information. 3/7
To be clear: Signal’s encryption and infrastructure have not been compromised and remain robust. These attacks were executed via sophisticated phishing campaigns, designed to trick users into sharing information – SMS codes and/or Signal PIN – to gain access to users’ accounts. 2/7
We are aware of recent reports regarding targeted phishing attacks that have resulted in account takeovers of some Signal users, including government officials and journalists. We take this very seriously. 1/7

📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms).
It’s also concerning. 1/
We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...
In 2023, Signal was the first mainstream messenger to enable post-quantum cryptography. We’re still ahead of the (elliptical) curve, implementing a new hybrid PQ ratchet ensuring Forward Secrecy & Post-Compromise Security even in a post-quantum world. signal.org/blog/spqr/
A reminder that Signal will never reach out to you proactively, never send you a Signal message, and never ask for your verification code. The only way to correspond with Signal is via email (support@signal.org) or the Signal Support Center (support.signal.org).
An illustration of me, and the headline: "AI agents are coming for your privacy, warns Meredith Whittaker The Signal Foundation’s president worries they will also blunt competition and undermine cyber-security"
To put it bluntly, the path currently being taken towards agentic AI leads to an elimination of privacy and security at the application layer. It will not be possible for apps like Signal—the messaging app whose foundation I run—to continue to provide strong privacy guarantees, built on robust and openly validated encryption, if device-makers and OS developers insist on puncturing the metaphoric blood-brain barrier between apps and the OS. Feeding your sensitive Signal messages into an undifferentiated data slurry connected to cloud servers in service of their AI-agent aspirations is a dangerous abdication of responsibility.
Happily, it’s not too late. There is much that can still be done, particularly when it comes to protecting the sanctity of private data. What’s needed is a fundamental shift in how we approach the development and deployment of AI agents. First, privacy must be the default, and control must remain in the hands of application developers exercising agency on behalf of their users. Developers need the ability to designate applications as “sensitive” and mark them as off-limits to agents, at the OS level and otherwise. This cannot be a convoluted workaround buried in settings; it must be a straightforward, well-documented mechanism (similar to Global Privacy Control) that blocks an agent from accessing our data or taking actions within an app. Second, radical transparency must be the norm. Vague assurances and marketing-speak are no longer acceptable. OS vendors have an obligation to be clear and precise about their architecture and what data their AI agents are accessing, how it is being used and the measures in place to protect it.
