GitHub cannot—and should not—ban all keyloggers. Security researchers need to study them. Red teams need to test defenses. But the current system of honor-based disclaimers is failing.

Several GitHub repositories provide Android keylogger source code, primarily for educational or security research purposes. These projects typically use Android's or custom Input Method Editors (IME) to capture keystrokes. Top Android Keylogger Repositories on GitHub

The app can log text input fields, capture button clicks, and scrape text dynamically as it appears across all other applications, effectively acting as a highly efficient keylogger without needing root access. Custom Virtual Keyboards

By using the SYSTEM_ALERT_WINDOW permission, an app can draw a transparent or spoofed window over a legitimate application (like a banking app) to capture touches and keystrokes.

: This is the most common method found in modern GitHub repositories. By requesting Accessibility permissions, an app can observe the screen content and user interactions (like text entry) across other applications without requiring root access.

Regularly review which apps have high-level permissions on your phone. Go to .

Utilizing the Telegram API to send logs directly to an attacker's private chat. Email (SMTP): Emailing text logs at scheduled intervals.

The "educational" label on a GitHub repository does not exempt its use from legal action. Developing, distributing, or using spyware is a violation of user privacy and computer security laws. Protecting Your Android Device

Many repositories are created by students or hobbyists learning Android development, reverse engineering, or malware analysis. They demonstrate how background services, broadcast receivers, and data serialization work in the Android ecosystem. Dual-Use Monitoring Software

Sending data logs to a remote server or a web panel hosted by the attacker.

Several repositories demonstrate different features and delivery methods:

GitHub hosts thousands of security-focused repositories. The presence of Android keyloggers on the platform generally falls into two categories:

The vast majority of malicious keyloggers cannot make it past Google Play Protect’s screening into the official Google Play Store. Instead, attackers distribute them as Android Package Kits (APKs) via third-party websites, phishing links, or alternative app stores. Restrict your device settings to block installations from unknown sources. 2. Audit Accessibility Permissions Rigorously
