Introduction
Telegram bots have revolutionized how users interact with the messaging app, offering tools for productivity, entertainment, and automation. However, their growing popularity raises critical questions about security. This guide explores the most popular Telegram bots while addressing vulnerabilities like EvilLoader and EvilVideo, and best practices to safeguard your data.

​Understanding Telegram Bots: Functionality and Risks

Telegram bots, powered by the Telegram Bot API, enable tasks like automated reminders (@AlertBot), translation (@YandexTranslate), and media sharing (@GifBot). While these bots enhance user experience, they operate outside Telegram’s default ​end-to-end encryption (E2EE), relying on TLS protocols instead of MTProto encryption. This gap exposes chats to potential interception, especially when third-party bots handle sensitive data.

​Critical Security Vulnerabilities in Telegram Bots

1. ​EvilLoader Exploit: A 2025 vulnerability allows attackers to disguise malicious APK files as videos, bypassing Telegram’s media validation. Once opened, these files execute JavaScript to steal IP data or install unauthorized software.
2. ​EvilVideo Flaw: Older Telegram versions (pre-10.14.5) risked device compromise via disguised malware files sent through chats. Always update to the latest version to patch such exploits.
3. ​Third-Party Risks: Bots like @GitHubBot and @MoviesTrackerBot may contain bugs or weak encryption, increasing exposure to data breaches.

​Top Secure Telegram Bots for 2025

1. ​**@ShieldyBot**: Automatically blocks spammers with CAPTCHA tests and kicks unauthorized users from groups.
2. ​**@LittleGuardianBot**: Filters malware and spam, with regular updates to counter emerging threats.
3. ​**@SkeddyBot**: Uses NLP for reminders while minimizing data exposure through localized storage.
4. ​**@MetricsBot**: Tracks website analytics securely within Telegram, avoiding third-party platforms.
5. ​**@Voicy**: Converts voice messages to text without storing data on external servers.

​Best Practices for Safe Bot Usage

• ​Enable Two-Step Verification: Add a password layer beyond SMS codes to prevent unauthorized logins.
• ​Avoid Unknown Bots: Verify bot credibility through Telegram’s new ​third-party verification system launched in 2025.
• ​Update Regularly: Patch vulnerabilities like EvilLoader by installing Telegram updates promptly.
• ​Restrict Permissions: Disable auto-downloads and limit bot access to contacts/files.

Conclusion
Telegram bots offer unparalleled convenience but require vigilance to mitigate security risks. By prioritizing verified bots, enabling two-factor authentication, and staying informed about updates, users can safely harness their potential.
