Summary: Big tech isn’t waiting around for regulators to stop global scammers. With AI working directly on your phone, Google is rolling out a new layer of defense against text-based fraud. The goal? Catch scams before they catch your money—and they’re doing it on your device, not in the cloud. No third parties, no data leaks, just smarter protection baked into your messages.
Scams Are Up. AI is Stepping In.
Americans lost $16.6 billion last year to online scams. That’s not a typo. It’s a hard number from the FBI, fueled by phishing attacks, spoofed websites, and fake text messages. Over 200,000 people reported these cyber crimes. Text scams alone stole more than $470 million, says the FTC. That’s nearly half a billion dollars vaporized from people’s bank accounts.
Google isn’t pretending this is someone else’s problem. As the operator behind the world’s largest mobile OS, Android, they’ve been under pressure to act. And not later—now. With Android 16 right around the corner, the company is going live with an expanded rollout of a surprisingly aggressive tool: Scam Detection for the Google Messages app.
Scam Detection: How Google’s AI Flags Fraud in Real-Time
Think of this like hiring a digital bouncer for your inbox. The new AI-driven feature doesn’t just sit back and wait for you to complain. It actively monitors texts for red flags—think crypto cons, fake prize winnings, “technical support” scams, impersonation of financial institutions, and gift card frauds. If they smell like scams, these messages trigger real-time warnings inside your Google Messages app.
The part that matters? It all happens locally on your phone. Unlike old-school filtering systems that ship your data to servers and analyze it in the background, Google built this detection system to run on-device. That means your messages aren’t leaving your smartphone. No text content gets sent to the cloud. No extra eyes on your conversations.
And it works at scale—Android’s AI is now spotting two billion suspicious messages a month.
Who’s Sending These Scams?
Scammers are global. But data shows that major clusters—especially out of China—are behind massive volumes of smishing attacks. These are often texts posing as postal services, telecom companies, or toll collection agencies. You click the link, and before you know it, you’ve handed over login info or credit card details. That’s their trick.
But not all fraud is fast. Some of today’s most dangerous crimes don’t look like scams at all. These are the long-haul cons—pig butchering scams. Think fake investment coaches, distant “lovers,” or social media friendships that slowly turn transactional. They build trust over weeks and months, coaching victims into emptying bank accounts—or worse, going into debt to send more money. That’s where AI has much more ground to cover.
Google’s Strategy: Build a Local Defense First
Google’s approach is smart. Instead of relying on users to report scams after the damage is done, they’ve invested in edge AI—machine learning models that live and compute directly on your device. The result is faster feedback, tighter privacy, and zero dependence on unreliable human reporting.
Dave Kleidermacher, VP of Security and Privacy at Android, says the company is “seeing really positive impact” already. As these systems get smarter, they don’t have to stay inside Google’s walled garden. There’s potential for extending scam detection to third-party chat apps. But for now, they’re keeping it inside their ecosystem.
Phone calls are next. Yes, the team is in early testing phases for scam call detection. It’s not wide release yet. But it’s on the radar.
This Isn’t Just a Google Problem
To be clear, Google isn’t flying solo. Other companies are punching back in creative ways:
- O2 in the UK built an AI “Granny” bot to waste scammers’ time on phone calls.
- Kitboga, the YouTube scambaiter, created a network of bots to flood scam call centers with useless activity.
- Meta now pops up warnings inside WhatsApp, Messenger, and Instagram chats if someone asks for a payment.
- F-Secure rolled out a feature to assess message sources and likelihood of fraud—nudging users to think first, act later.
All these efforts share a common trait: slowing scammers down. Adding friction. Disrupting the smooth flow from message to monetary theft.
Why On-Device AI Changes the Game
There’s a few reasons this matters:
- Better Privacy: Nothing leaves the phone. You’re protected without uploading chat logs to a third-party server.
- Faster Detection: Because it happens locally, warnings appear in real time—not hours after the scam hit you.
- Scalable Defense: Two billion messages flagged monthly means the system is already catching signals at massive scale.
What’s Next—And What’s Not Ready Yet
Longer-term, the system could be embedded into other messaging platforms. Think WhatsApp, Telegram, or even SMS services offered by third-party carriers. But Google hasn’t confirmed that step yet. For now, the focus is on tightening the screws inside Google Messages and incrementally introducing detection features for scam phone calls.
Even then, pig butchering scams may still slip through. These threats evolve. They’re patient. And they often mirror authentic human conversations. That’s a tougher nut to crack and will require more context-aware AI systems in the future. But it’s no reason to delay sandbagging the front lines today.
The Real Win: Trust Without Oversharing
Trust in software usually comes at a cost—often your own data. What Google’s doing here flips that trade-off on its head. They’re giving you tools that fight fraud without giving them your message contents. That changes the dynamic. That builds long-term confidence. And if it pushes competing platforms to do the same, the whole ecosystem improves.
Is it perfect? Not yet. But it’s a solid move in a world getting buried under a mountain of disinformation and low-effort scams.
