Google Opens Registration for Registered App Stores Program to Simplify Third-Party App Installs on Android

Google has opened registration for its new Registered App Stores program, enabling approved third-party app stores to install applications with a single tap and perform background updates on Android devices. The program introduces stricter compliance requirements, including an annual $10,000 registration fee paid before review, mandatory submission of all APK files and updates for malware scanning, and organizational verification. These features will become available starting December 1, 2026, on devices running Android 17 QPR2 and newer versions, with Russia listed among supported countries. Stores that remain outside the program can continue using the existing multi-step installation process. Google will impose additional fees if more than 1% of installation attempts or 2% of catalog applications are flagged as potentially malicious within any 30-day period. The initiative aims to balance user convenience with enhanced security controls while remaining entirely voluntary for alternative app distributors.

Free Ad Blocker for iPhone, Android, and Desktop Uses DNS Parsing Without Libraries and Skips YouTube Influencer Ads From the First Second

A new free ad-blocking solution has been released for iPhone, Android, and desktop platforms. The tool relies on a lightweight DNS parser that operates without external libraries. It includes a dedicated mode for users who already run VPN connections. An accompanying browser extension automatically skips sponsored segments in YouTube videos, even when the advertisement begins at the zero-second mark. The developer describes the technical challenges encountered after launch and the fixes applied to maintain compatibility across operating systems. The project emphasizes user privacy by avoiding unnecessary data collection and third-party dependencies.

Microsoft Expands Android Integration in Windows 11 with Start Menu Notifications and File Explorer Access

Microsoft has outlined plans to integrate Android smartphones more deeply into Windows 11, reducing the need to reach for a physical phone. Messages and notifications from linked Android or iPhone devices will appear directly in the Start menu, while conversations can be opened in resizable separate windows. Quick Settings will include controls to mute the phone or trigger its ringer for locating a lost device. For compatible Android phones, users will be able to run mobile apps in independent windows and browse phone files through File Explorer. A notification will appear on the desktop after taking a photo on the phone, allowing one-click access to the image. The Resume feature will also enable seamless continuation of supported tasks when switching between devices. These enhancements build on the existing Phone Link app but embed the functionality more natively into the Windows interface.

NICT Warns of A2B Attacks Where Reverse-Engineered Android Apps Expose Vulnerable Backend Servers

Japan's National Institute of Information and Communications Technology (NICT) has issued an alert on A2B attacks, in which publicly available Android apps are reverse-engineered to identify and target their backend servers. The technique, called App-to-Backend Attack, allows threat actors to discover internal server endpoints even when organizations do not publish connection details. Once identified, attackers exploit vulnerabilities, weak authentication, or misconfigured APIs on those servers, leading to unauthorized access and data theft. NICT notes that multiple recent membership-service breaches in Japan stem from this vector rather than flaws in the mobile apps themselves. The institute urges developers and operators to harden backend infrastructure, conduct thorough compromise assessments, and apply proper access controls. Related incidents include unauthorized access to Lawson ID services, Yakiniku King app member data, and Japan Post's postal app.

MegaFon Reports 34% Rise in Russian Mobile Malware Infections Driven by Android Trojans

MegaFon monitoring data shows a 34% year-over-year increase in Russian users with detected mobile malware during summer 2026, with the sharpest spike of 77% recorded in August. The growth is primarily attributed to Android trojans capable of installing apps without user consent, intercepting notifications, enabling remote access, and stealing personal data. At the same time, blocked suspicious calls dropped significantly, by 31% in June, 41% in July, and 75% in August, which the operator links to state and corporate anti-fraud measures. Scammers are adapting by hijacking messenger accounts through social engineering, malware, and even rental schemes, often combining calls with fake app installations that deploy spyware. Phishing remains active, with 30% of detected malicious resources tied to investments and crypto, 21% to social networks and messengers, and 9% to harmful APK files. Director Sergey Khrenov noted that smartphones are increasingly used as tools by the attackers themselves in these hybrid schemes.

Silent Call Answering on Android: Defeating Phone Spam by Removing Human Attention

A detailed proposal suggests abandoning traditional spam call blocking in favor of allowing all incoming calls to connect automatically while keeping them invisible to the user. The approach uses Android's Telecom Framework and InCallService to answer calls silently without ringing, notifications, or screen activation. This breaks the economic model of mass dialing systems by inflating answered call metrics with empty connections that contain no human. The concept separates the technical establishment of a call from delivering user attention, forcing spammers to detect real people after the connection is made. Implementation requires the app to hold the ROLE_DIALER role and selectively invoke Call.answer() based on custom rules instead of always showing the incoming call UI. The author argues this shifts the detection burden onto robocall platforms and reduces the value of every successful connection.

Google Developing Voice-Activated Emergency SOS Feature for Android Devices

Google is working on a voice-activated Emergency SOS function for Android that would allow users to summon help without touching their smartphone. The feature, discovered in the Personal Safety app code by Android Authority, appears to trigger after the user says the word 'Help' three times in sequence. Once activated, the system would automatically determine location, begin emergency video recording, and place a call to emergency services. The current method requires pressing the power button five times, which can be impractical in certain situations. Additional code strings suggest optional voice confirmation with phrases such as 'Say yes to continue' and 'Say cancel to dismiss Emergency SOS'. The function is not yet available to users and may eventually reach non-Pixel devices running the Personal Safety app, though supported languages and models remain undisclosed.

Russia's MinTsifry Flags Google Android Developer Verification Rules as Risk to Domestic Apps

Russia's Ministry of Digital Development is assessing new Google policies that will require developer registration for Android apps distributed outside Google Play. The changes, starting in select countries in 2026 and expanding globally in 2027, could block sideloading of Russian applications previously removed from official stores due to sanctions. Minister Maksut Shadaev described the scenario as a potential barrier where users may no longer freely install APK files from third-party sources. Google plans to retain advanced modes and ADB installation options with extra warnings for unverified apps. Custom firmware projects such as LineageOS have stated their devices will remain unaffected by the verification system. Russian banks, marketplaces, and other services that rely on direct APK distribution are viewed as the most exposed.

Researchers Create 0-Click WeChat Worm That Hijacks Accounts via Incoming Calls

Security researchers at Calif have developed a 0-click worm capable of compromising WeChat accounts through incoming voice calls without any user interaction. The exploit requires only that the attacker already exists in the victim's contact list and works across Android and iOS devices. In demonstrations, an infected Android device called an iPhone to seize control of its WeChat account while the call continued ringing, after which the compromised iPhone targeted another Android device. The worm spreads automatically between trusted contacts, functioning like a classic network worm but using WeChat profiles as propagation nodes. Even if the victim answers or declines the call, the exploit can persist or be retried, for example during nighttime hours. After account takeover, attackers gain full control to read and send messages, make calls, and impersonate the owner, while the underlying smartphone itself remains unaffected. Tencent received notification in July, released patches in versions 8.0.77 for Android and 8.0.76 for iOS, and server-side blocking was confirmed by late August, with no real-world attacks observed so far.

Google to Add Explicit Content Warnings in Android System Photo Picker

Google is preparing a new safety feature for the system photo picker in Android that will scan images and videos for explicit or nude content. The tool is designed to warn users before they share intimate photographs, whether accidentally or due to a momentary lapse in judgment. This functionality will operate at the system level, meaning it applies across multiple apps that use the built-in photo selector. The feature aims to reduce the risk of unintended distribution of private images that could lead to embarrassment or privacy violations. By integrating the check directly into Android, Google seeks to provide a consistent layer of protection without requiring third-party applications to implement similar logic themselves.

Google Introduces Multi-Step Verification for Android APK Sideloading to Combat Fraud

Google has begun rolling out an enhanced installation flow for Android apps installed outside of Google Play. Users must first confirm that no one is coercing them to enable unknown sources, then reboot their device and wait 24 hours before the option becomes available. The new process includes explicit warnings about scammers who pressure victims into enabling sideloading, noting that legitimate organizations never require this setting. After the waiting period, users can grant the permission for seven days or indefinitely. The change does not affect ADB installations, preserving a workaround for advanced users. Google states the delay is intended to give people time to reconsider before enabling potentially risky settings. An Android Authority poll showed 88 percent of respondents expect further restrictions in the future.

Google Develops Public Android API for On-Device Content Safety Classification

Google is creating a new public Android API that will allow third-party applications to analyze images and other files locally on the device and assign them one of four safety statuses. The system builds on the existing SafetyCore component already used in Google Messages to blur intimate images. ContentSafetyManager will process images, raw files, and multimedia content entirely on-device without transmitting data to Google servers. Applications will then decide whether to display, blur, or hide the content based on the classification result. Experts warn that malicious apps granted broad permissions could misuse the classifier to scan large volumes of user files and build detailed profiles. SafetyCore itself previously sparked controversy after being installed automatically without explicit user consent and without a visible icon, leading some users to install blockers to prevent reinstallation via the Play Store. Google continues to emphasize minimal permission requests and local processing as safeguards for user privacy.

WhatsApp Adds Support for Multiple Passkeys on Single Account

WhatsApp has expanded its account protection features by allowing users to register more than one passkey on the same profile. The update particularly benefits users who switch between Android and iOS devices while maintaining phishing-resistant login methods. Passkeys replace traditional codes and passwords with biometric authentication, facial recognition, or device lock mechanisms. Meta reports that more than one billion people already use the feature on WhatsApp, with Android support introduced in 2023 and iOS support added in 2024. The change reduces reliance on a single device during authentication by associating multiple keys with one account. Users can manage keys through Settings > Account > Passkeys. WhatsApp has also strengthened two-factor verification by allowing replacement of the six-digit PIN with longer passwords containing letters, numbers, and special characters.

Ruthenium: Custom Chromium Build for Android Adds Russian Trusted Root CA Support

A developer has released Ruthenium, a modified Chromium browser for Android that embeds the Russian Trusted Root CA certificate issued by the Ministry of Digital Development. The build restricts trust to .ru and .рф domains only, avoiding changes to the system-wide Android certificate store. The project patches four Chromium source files to include the root with DNS constraints via CertWithConstraints, disables Google sign-in by default, and removes XR-related code for successful compilation. Ruthenium uses the official Chromium TLS verification logic without introducing a custom verifier. The APK is distributed with SHA-256 checksums, build metadata, and reproducible release tags tied to the exact Chromium revision and certificate digest. Users can install it alongside stock Chrome and use it selectively for Russian government and banking sites that rely on the state root.

US Federal Judge Orders Google to Simplify Installation of Third-Party App Stores on Android

A federal judge has directed Google to remove extra warnings and confirmation steps when users install competing app stores through Google Play on Android devices. The ruling stems from the ongoing antitrust litigation between Epic Games and Google, where a jury previously found that Google illegally maintained a monopoly over Android app distribution and in-app payments. Judge James Donato criticized the current multi-screen process as an intentional barrier designed to discourage ordinary users from choosing alternatives. Google must implement the changes within one week, making the installation of third-party stores as straightforward as any other Android application. The decision acknowledges that while Android has long permitted sideloading, the layered security prompts and hidden permission toggles effectively steered most users back to Google Play. Aptoide has already appeared in the US Google Play store as the first third-party marketplace to benefit from the eased process. Google argued the warnings protect users from malware, but the court rejected the notion that security should serve as a shield for market dominance.

Google Chrome Blocks Over 7 Billion Unwanted Notifications Daily on Android

Google reported that its Chrome protection systems blocked more than 7 billion unwanted notifications every day on Android during the first quarter of 2026. Websites increasingly use browser notifications to deliver phishing attempts, fraudulent payment requests, and malware. Chrome applies a multi-layer "Swiss cheese" defense model where several overlapping filters compensate for each other's weaknesses. The browser automatically revokes notification permissions from sites that have not been visited recently or that trigger repeated security warnings, and it can also cancel associated subscriptions. For particularly noisy resources, Chrome enforces a hard limit of 1,000 messages per minute and returns HTTP 429 responses to excess traffic. Google also made permission prompts less intrusive on Android, which reduced background activity and improved battery life. Users can review and manage notification permissions through Safety Hub on both desktop and mobile versions of Chrome.

Kaspersky Adds Call Filtering to Kaspersky Secure Mobility Management for Android Devices

Kaspersky has introduced call control capabilities into the expanded version of Kaspersky Secure Mobility Management. The new feature allows corporate Android devices running Kaspersky Endpoint Security for Android to check incoming call numbers against both local offline databases and global online reputation sources. Depending on company policy, the system can display warnings to employees or automatically block suspicious calls. Administrators gain the ability to define rules by call category, maintain black and white lists, and apply different policies to specific employee groups. The update targets risks from telephone fraud and social engineering attempts that aim to extract confidential corporate information or funds. It also helps reduce unwanted spam calls that disrupt staff who handle high volumes of incoming communications. Kaspersky Secure Mobility Management provides full lifecycle control over corporate mobile devices, applications, data, and security policies.

Yandex Details Alice Voice Assistant Audio Buffering and Data Handling in Android Apps

Yandex has issued a detailed technical response to an analysis of its Android applications that raised concerns over potential collection of audio, contacts, bank card data, and other sensitive information. The company acknowledged the existence of a cyclic audio buffer that retains approximately 1.5 seconds of sound before an activation phrase and 0.5 seconds after it, with some pre-command audio possibly transmitted to servers for speech recognition quality checks. Yandex clarified that the Alice assistant only listens locally for the wake word when the app is open and does not continuously record conversations. Access to contacts was explained as necessary for voice commands such as calling entries from the address book, with the full book sent on first sync and only changes thereafter, without hashing to support accurate speech processing. The firm rejected claims of reading messaging app conversations and stated that bank card details are routed directly to an isolated PCI DSS-compliant environment rather than standard application servers.

WhatsApp Developing AI Content Labeling Feature for Channel Admins to Meet EU Transparency Rules

WhatsApp, owned by Meta, is rolling out a new function that allows channel administrators to mark posts containing AI-generated or AI-edited media. The feature appears in the latest Android beta and stems directly from European Union requirements for transparency around artificial intelligence content. Administrators can long-press a message after publication and select an option to add an AI content label, which then displays a visible tag informing subscribers that the material was created or modified by neural network tools. The requirement applies specifically to images, videos, and other media files, while generated text remains exempt from mandatory labeling. WABetaInfo researchers spotted the change, noting that the label may become permanent once applied and that the rollout could initially target only jurisdictions with relevant legislation. Broader availability for iOS users and global deployment remain under consideration.

Telegram Removed from App Store After Extortionist Plants AI-Modified CSAM in Archived Message

Pavel Durov stated that an extortionist edited an old public group message by inserting AI-altered child sexual abuse material, allowing the post to evade detection by active chat participants while enabling a direct report to Apple. The tactic triggered automatic removal of Telegram and experimental Telegram X from the App Store in multiple countries including Russia, Turkey, and the United States on August 4. Apple restored the applications after Telegram deleted the prohibited content and blocked the responsible account, with the entire outage lasting approximately ninety minutes. During the incident, push notifications failed for some iOS users, while macOS and Android versions remained unaffected. Durov criticized Apple for suspending the app without prior contact and warned that the same mechanism could be used against any user-generated content platform. Telegram urged Apple to apply equal scrutiny to all incoming reports rather than acting on isolated complaints that bypass normal moderation filters.

EU Forces Google to Open Android Microphone, Camera and Screen Access for Rival AI Assistants

The European Union has ordered Google to provide competing AI assistants with the same level of access to sensitive Android resources that is currently reserved for Gemini. The ruling covers eleven system functions, including voice activation, home button integration, background execution, and on-device AI model access. Rival assistants will also gain real-time environmental data streams from the microphone, camera, screen, and speakers under identical consent and notification rules applied to Google services. Additional capabilities include cross-app interaction, messaging, scheduling, device settings control, and multi-step task automation. Screen automation will allow assistants to operate apps inside a virtual window while the user performs other activities. Most changes are scheduled for Android 18 by 1 August 2027, while simultaneous activation of multiple assistants by voice keyword will arrive in Android 19 no later than 1 August 2028. Access to the most sensitive functions may require objective security certification and explicit user authorization.

Google Quietly Rolls Out Android Developer Verifier App to Curb APK Sideloading Fraud

Android users are discovering a new system application called Android Developer Verifier with the package identifier com.google.android.verifier that Google installs automatically through system updates without any separate consent prompt. The service prepares devices for upcoming restrictions on installing APK files from unknown sources by checking whether an app is registered to a verified developer who has passed identity verification and supplied legal information to Google. This verification does not guarantee an application is safe but allows Google to associate it with a specific individual or company, helping combat social-engineering scams in which fraudsters pressure victims into disabling protections and installing malicious APKs. To install software from an unverified developer, users will need to enable developer mode, confirm they are not under duress, reboot the device, wait 24 hours, and re-authenticate with PIN or biometrics. The new requirements begin on 30 September in Brazil, Indonesia, Singapore, and Thailand, with worldwide expansion planned for 2027 and later. While the app can currently be removed, it is unclear whether future updates will restore it, and advanced users retain the option to sideload via ADB, which bypasses the new checks entirely.

69% of Browsers Worldwide Vulnerable: How Chrome Sync Enables Stealth Surveillance Without Malware

Google Chrome's standard synchronization feature can be silently abused to turn any browser into a surveillance tool, requiring only brief physical access to a victim's device and the addition of an attacker's Google account. Security researchers at Certo highlighted the technique after multiple cases involving intimate partner surveillance, including one incident where a woman’s visits to a family lawyer and domestic abuse support sites were monitored in real time by her partner. Once sync is enabled, browsing history, bookmarks, open tabs, autofill data, and saved passwords are automatically transmitted to the attacker’s profile, which can be viewed from any device worldwide without needing the victim’s password or installing spyware. Chrome provides no prominent warnings about new profiles or active synchronization, and alerts about logins are sent only to the account owner rather than the device owner. With Chrome holding a 69.65% global market share according to StatCounter data from June 2026, the method potentially affects millions of users on Android, iOS, Windows, and macOS. Experts recommend regularly checking connected profiles in browser settings, using Incognito mode for sensitive activity, securing devices with strong passcodes and biometrics, and immediately removing unknown accounts while changing important passwords.

VK Sells 100% of RuStore to CEO Dmitry Pankrushev, Transferring Full Control to Management Team

VK has reached an agreement to sell its entire stake in the Russian Android app store RuStore to the company's own general director, Dmitry Pankrushev. The transaction moves RuStore out of direct corporate control by VK and places it under the leadership of the team that has been managing its day-to-day operations. No financial details, including the purchase price or payment structure, have been disclosed. VK described RuStore as Russia's single point of access to essential Android services and as a key platform supporting local application developers. After the deal closes, the existing team has committed to continuing regular updates, expanding features, and maintaining stable service for users. On the surface, end-users should notice no immediate changes in availability or functionality, yet the shift represents a significant structural change for one of Russia's most important alternative app marketplaces.

Google to Allow Competing Android App Stores Directly Inside Play Store After Epic Games Court Ruling

Google is preparing to open its official Google Play store to rival Android app marketplaces starting July 22, following a court order issued in the long-running antitrust lawsuit with Epic Games. The ruling stems from the 2020 Fortnite dispute over Google’s 30% commission and direct in-app purchases that bypassed the platform’s billing system. A federal judge determined that Google had unlawfully prevented device makers from promoting or pre-installing alternative app stores, thereby reinforcing Google Play’s monopoly position. As a result, approved third-party stores will now be distributed directly through Google Play, receive default access to its app catalog, and be subject to an annual $5,000 verification fee. Developers retain the right to block distribution of their apps on specific stores, while participating marketplaces must meet strict security, copyright, and update obligations or risk removal if suspicious installations exceed 1%. Although the changes are expected to apply primarily in the United States, the decision marks a fundamental shift in how Google must accommodate competitors within its own ecosystem.

Google Enhances Android Backup Controls in Play Services Update, Adds Document Sync to Google Drive Amid Storage Limit Cut

Google is updating its Android backup system through Google Play Services version 26.25, introducing separate toggles for messaging backups and the ability to automatically save documents to the cloud. Users can now disable SMS, MMS, and RCS backups independently, though RCS remains nested under the MMS category for less visibility. The new document backup feature supports formats including DOC, PPT, XLS, and PDF, storing copies in a device-named folder on Google Drive without automatic synchronization to the original files. These changes coincide with Google's reduction of free storage from 15 GB to 5 GB, where Android backups now count against the quota, potentially turning small 40 MB backups into much larger archives. The update provides more granular control over what gets backed up, including call history and system settings, accessible via Settings > Accounts and backup > Google Backup > Other device data. While the feature can help preserve important files, it risks quickly exhausting limited free storage if documents are included.
