Google Expands AI-Powered Scam Protection for Android
Google announced new and enhanced security measures for Android devices to combat increasingly sophisticated scams, including AI-powered fraud detection that identifies over five million suspected fraudulent calls and messages monthly. The update expands the protection mode in Google Messages, which now leverages larger Gemini models in the cloud via Private AI Compute for complex text conversations from unknown senders. Gemini Nano on-device checks new web links in real-time. New protections also include blocking background call forwarding, warning users before enabling MMI codes, and verifying incoming calls from banks against official bank apps to prevent caller ID spoofing. Google reports that since June, this bank verification feature has blocked over three million fake calls from Banco do Brasil and Itaú Unibanco alone, with partners including Revolut and several major banks. Enhanced scam warnings for suspicious chat notifications will roll out to non-Pixel devices later this year.
As a major platform security update, these measures strengthen user trust and security, which is crucial for the digital advertising ecosystem that relies on safe mobile environments for user engagement and data protection.

Google adds AI scam-call warning to Android Phone app
Google has introduced a new AI-based scam-call warning in its Android Phone app to help users detect calls that use AI-generated voices to impersonate contacts. The feature, available free via Google Play and automatically active for users of the Google Phone app, exchanges encrypted real-time data between devices to verify whether the displayed caller is the genuine contact; if verification fails the app pings the alleged contact's device and, based on the response, warns the recipient, reports and blocks the number. The rollout begins this month on Pixel phones and will expand to other Android devices running Android 12 or later. Google built the system on the RCS standard so other companies can implement the same verification in other calling apps.
Google launches fake-call detection to block AI deepfakes
Google announced a new fake call detection feature for Android that aims to protect users from AI voice deepfake impersonation scams. Rolling out globally this month in the Phone by Google app for Android 12+ devices (starting with Pixel phones), the feature is enabled by default and runs automatically. It uses a silent confirmation signal — described as a “digital handshake” built on Rich Communication Services (RCS) — between devices when both caller and recipient use Phone by Google; missing confirmation triggers a verification ping to the caller’s device and, if the real device confirms no call is in progress, the recipient sees a warning to hang up. The announcement was published June 2, 2026, alongside other Android updates such as Google Photos’ wardrobe feature and Play Books’ recap tools.
Google sues alleged AI-backed Chinese SMS scam ring
Google has filed a lawsuit seeking to dismantle the infrastructure of an alleged China-based cybercrime network called Outsider Enterprise that used AI to run large-scale phishing and SMS-scamming campaigns. Google alleges the group deployed thousands of fake sites and domains and sent millions of fraudulent texts impersonating Google and other brands to harvest credentials and payment data. The company says it detected more than 1.59 million URLs tied to Outsider between Nov 14, 2025 and Apr 14, 2026 and flagged intense activity (9,000 fake sites, one million fraudulent domains, 2.5 million texts in a two-week span). Google is coordinating with carriers (AT&T, T‑Mobile, Verizon) and the FBI; the FBI and Lumen’s Black Lotus Labs have seized domains and storefronts. Authorities estimate millions of stolen cards and billions in losses tied to the platform.
