Google has adjusted its identity verification plan for Android developers distributing apps outside the Play Store in response to developer community concerns. A new installation process is being created for experienced users who sideload apps from unverified developers, addressing fears that the original policy would limit sideloading capabilities. Initially, the policy required developers to provide personal information, which faced backlash from privacy advocates and open-source communities. Despite this, Google is moving forward with the verification system, launching an early access portal for developers on November 12, 2025. The new installation workflow will include multiple warnings and safeguards for users installing unverified software. Additionally, a lighter verification tier will be available for students and hobbyist developers, allowing them to bypass full identity requirements while limiting app distribution. The verification system aims to combat scam apps by linking developer accounts to real-world identities. The rollout of the new verification system will begin regionally in 2026 and expand globally in 2027. This policy shift coincides with a settlement between Google and Epic Games to reduce developer fees and support third-party app stores, pending judicial approval.

A banking trojan named Herodotus targets Android users globally, operating as Malware-as-a-Service and disguising itself as a legitimate app to lure users into downloading an APK from unofficial sources. Once installed, it gains critical system permissions to perform banking operations on behalf of the user. The malware is primarily distributed through SMS phishing campaigns that lead victims to fraudulent download pages. Herodotus employs overlay attacks to steal credentials and hijack sessions, posing a significant threat to financial security. It uses advanced evasion tactics, including random delays and realistic typing patterns, to avoid detection by traditional antivirus solutions. The trojan captures screen content and keystrokes, allowing real-time monitoring of user activity. Detection is complicated as Herodotus circumvents defenses by installing from unknown sources and executing harmful actions only after obtaining user permissions. Effective defense requires recognizing multiple indicators of compromise, such as suspicious SMS links and behavioral anomalies, which traditional antivirus protection often overlooks.

A sophisticated Android remote access trojan (RAT) has been discovered on GitHub, named "Android-RAT," created by the user Huckel789. This malware is fully undetectable (FUD) and can bypass modern security measures and antivirus systems. It operates through a web-based interface without requiring installation on a PC, making it accessible to users with varying technical skills. The RAT exploits GitHub's trusted platform status to evade security filters and includes features such as keylogging, credential hijacking, ransomware functionality, and social engineering tools. The malware employs advanced stealth techniques to avoid detection by antivirus solutions and VirusTotal scans, integrating anti-emulator and virtual machine detection mechanisms. It can persist through battery optimization modes and power management restrictions, particularly in Chinese ROMs like MIUI, while consuming minimal system resources. The RAT's communication infrastructure uses AES-128-CBC encryption for secure data transmissions, complicating network traffic analysis. Its "Freeze Mode" limits data transmission to 1-3MB over 24 hours, reducing the likelihood of detection. Additionally, the malware can inject its payload into legitimate applications via a dropper module, making initial infection vectors difficult to identify.
