Consumer-grade spyware applications, often referred to as "stalkerware" or "spouseware," pose significant risks to Android users by monitoring private messages, photos, phone calls, and real-time locations without consent. These apps are typically downloaded from outside the Google Play Store and can be stealthily installed, often disappearing from the home screen. Stalkerware exploits legitimate Android features, leading to unusual phone behavior such as excessive heat, sluggish performance, or unexpected data usage. To address spyware, users should establish a safety plan and trusted support before attempting removal, as this could alert the installer. Google Play Protect should be enabled to scan for harmful apps. Users should check for unfamiliar apps in accessibility services, review notification access for third-party applications, and inspect device admin app settings for unrecognized applications. Even hidden stalkerware apps will appear in the list of installed applications, which can be accessed through the settings menu. Strengthening device security, such as enhancing lock screen passwords and using two-factor authentication, is recommended. Resources for support include the National Domestic Violence Hotline and the Coalition Against Stalkerware.

Google is enhancing security measures for Android users by introducing a feature in Chrome for Android that will scan APK files for malware. This feature, currently in testing in Chrome Canary, will automatically check the safety of newly downloaded APK files, providing extra security for users who sideload applications. Play Protect already scans newly downloaded apps for malware and monitors installed applications for potential threats, alerting users and managing app permissions. The upcoming feature aims to improve security for sideloaded applications and reduce risks associated with harmful installations.

Apple devices, particularly Macs, are facing an increase in cyberattacks, with a new wave of sophisticated malware targeting sensitive data. The emergence of Atomic Stealer (AMOS) in mid-2023 marked a shift from less harmful adware to more serious threats, with AMOS being marketed as a user-friendly service. By mid-2024, Poseidon became the leading Mac information stealer, responsible for 70% of infections and capable of draining various cryptocurrency wallets and capturing sensitive credentials. Cybercriminals are also using malvertising to lure users into downloading disguised malware. Android users are experiencing an even more severe situation, with a significant rise in phishing attacks. In 2024, researchers identified 22,800 malicious apps designed for phishing, along with thousands capable of reading one-time passwords (OTPs). These apps often mimic legitimate software and can easily infiltrate app stores, including Google Play. While Google Play Protect offers some malware protection, it is not entirely effective. To protect against malware threats, it is recommended to use strong antivirus software, be cautious with downloads and links, keep software updated, use strong and unique passwords, and enable two-factor authentication (2FA) for critical accounts.

Google is developing a new security feature for Android 16 that will block changes to sensitive settings during phone calls to protect users from phone scams. This feature will prevent users from enabling sideloading permissions and granting accessibility access while on a call. A warning message will be displayed if users attempt to make such changes, informing them that these actions are prohibited during calls. The sideloading permission is disabled by default, but users can enable it through settings, except for those with Advanced Protection Mode activated. These security features are expected to be included in the public release of Android 16 later this year.

Google's Android Security and Privacy Team has partnered with Mandiant FLARE to enhance the capa open source binary analysis tool, which analyzes ARM ELF files used in Android malware. The integration of Gemini AI into this toolset aims to improve malware analysis and decision-making. A case study demonstrated the detection of an illegal gambling app disguised as a music app that used various anti-analysis techniques. By employing static analysis with capa, Google was able to identify and remove the app from the Google Play Store. New rules have been developed for capa to detect Android-specific malware behaviors, such as ptrace API calls and code downloading and decrypting methods. The incorporation of Gemini AI aids analysts by summarizing flagged functions and assessing risk levels, thereby accelerating malware detection and rule formulation.

Some Android applications are covertly monitoring conversations and collecting personal data without user consent. Cybersecurity firm ESET identified six malicious apps on Google Play and another six on third-party app stores that disguise themselves as legitimate messaging platforms. These apps harvest data such as text messages, call logs, and recorded conversations. Hackers also employ tactics like creating fake romantic connections to persuade victims to download infected apps, such as those containing the VajraSpy Trojan, which records conversations and accesses personal files. Three groups of dangerous apps include: 1. Messaging apps disguised as secure platforms (e.g., Hello Chat, MeetMe, Chit Chat) that steal contact information and SMS messages. 2. Apps exploiting accessibility features (e.g., Wave Chat) that can intercept messages and record phone calls. 3. A fake news app that seeks access to personal data without messaging capabilities. A list of malicious apps includes: Rafaqat, Privee Talk, MeetMe, Let’s Chat, Quick Chat, Chit Chat, YohooTalk, TikTalk, Hello Chat, Nidus, GlowChat, and Wave Chat. Six of these apps were downloaded over 1,400 times each before being removed from Google Play. To protect privacy, users are advised to uninstall suspicious apps, change passwords, enable two-factor authentication, run security scans, and stay informed about cybersecurity threats.

Google Play Protect is enhancing security for Android devices by automatically disabling app permissions for potentially harmful applications, preventing access to sensitive information. Users can restore permissions but must confirm their decision, promoting caution. Play Protect scans all apps, including sideloaded ones, and blocks harmful applications based on threat levels, scanning over 200 billion apps daily. It also prevents users from disabling Play Protect during phone and video calls to combat social engineering scams. In 2024, Google blocked 2.36 million policy-violating apps and banned over 158,000 fraudulent developer accounts, introduced live threat detection for Pixel devices, and launched a verification badge for trustworthy VPNs.
