Was curious if I could use AI (Graylark) to find coordinates of this house using just a *reflection in a keypad* of the surroundings. Well...it worked. YIKES. Daniel Heinen does not make this AI tool available to the public for this reason. youtube.com/shorts/Xzbvi...

Can AI geolocate using just reflections?!

Ooo super interesting to see! That Scam Detection tool you’re seeing (using AI to privately analyze potential scam pretext within call) is different from Fake Call Detection (RCS to determine if call is a spoof of trusted contact). Looks like Scam Detection is triggering bc of the car-based call.

Rachel Tobac @racheltobac.bsky.social · 04/06/2026

Oh fascinating! Tell me more about the false positive and I’ll tell the team. What do you think caused it? What was the circumstance of the call?

Rachel Tobac @racheltobac.bsky.social · 03/06/2026

Yes there is haptic feedback which makes a vibration and noise during the alert so you can feel/hear it if you can’t see your phone during a call. We tested this during UX research ◡̈

In the age of tech companies consistently doing shitty things, this is genuinely cool and a smart solution to stopping Scammers with RCS (meaning it's encrypted and private too)!

Great question, to the best of my knowledge the ping is to question a binary “on a call” or not status which limits scammer success.

Rachel Tobac @racheltobac.bsky.social · 02/06/2026

Android now but they built the tool on RCS which is an open standard, specifically so other apps and devices manufacturers can adopt the technology for free!

Rachel Tobac @racheltobac.bsky.social · 02/06/2026

Fake call detection is on by default and works automatically on Android 12+ devices (so even older phones) Note: Love that this digital check uses *end-to-end encrypted Rich Communication Services (RCS) technology, and is completely private.* You can also turn this feature off if you prefer.

3. If it’s missing, your device pings your contact's actual device to double-check their device is placing the call. If their real device says, "I'm not making a call right now," you'll get a warning on your screen about the spoof attack in action.

Rachel Tobac @racheltobac.bsky.social · 02/06/2026

Ok, so how does fake call detection work?! 1. Attacker impersonates your contact by spoofing their number + voice cloning to steal your money, data, access, etc. 2. Your device knows your real contact’s 'digital handshake' confirmation signal, so when it’s missing, it notices. Continued below…

WHOA Google let me know they saw my tweet last year & built a tool to defend against the exact call spoofing + AI voice clone attack! As of *today*, fake call detection on Android alerts when someone is impersonating your contact. Thread and demo below:

Whoa, Instructure (who owns Canvas) says they came to an agreement with the cyber criminals (typically this means a ransom was paid) in exchange for the stolen data being deleted instead of leaked and criminals ceasing all extortion requests from customers. Huge development.

WARNING, fellow journalists: As @nicoschmidt.io explains, attackers are trying to hijack reporters' Signal accounts by tricking people into handing over their 2FA codes. www.linkedin.com/posts/nicosc...

In the last days, there has been an unprecedented attack targeting investigative journalists trying to seize their Signal accounts. This has gone largely unreported.

I have been repeatedly targeted by phishing, and I learned that also colleagues from other outlets were targeted, with the attackers unfortunately managing to compromise at least one colleague’s account. What’s worrying: this doesn’t seem like an isolated case. A broader wave is apparently hitting journalists (and some civil society actors) via Signal.

How it works: Attackers message you on Signal pretending to be “Signal Support,” warning about “suspicious activity,” and urging you to “re-verify” your account. Once you accept the chat, you receive a real Signal SMS verification code, because the attacker is actively trying to register your number on a new device. If you share that code, you’re handing them the keys.

Signal’s extra protection is the Signal PIN. If an attacker also tricks you into giving up your PIN (or you don’t have strong protections enabled), they can see your contacts and networks, potentially join chats going forward, and lock you out by changing settings.

Quick protections worth doing today:
- Signal will never contact you via a two-way in-app support chat. Treat those messages as hostile.
- Never share SMS codes, Signal PIN, or anything called “registration lock.”
- Turn on Registration Lock (Settings → Account → Registration Lock).
- If you see a “safety number changed” alert: verify the person via a different channel (call/video), not just Signal text.
- Report + block suspicious requests, and review linked devices.

If you work with sensitive sources: this isn’t just about losing an account, it’s about exposing networks. Please share this with colleagues who rely on Signal day-to-day.
