When a victim receives a malicious file via Telegram, the platform incorrectly interprets the .htm file as a video due to manipulated metadata headers.

Mitigation Recommendations

Ensure installation of version ≥10.14.5, which enforces stricter file validation.
Navigate to Settings > Data and Storage > Automatic Media Download and disable all chat types.
Train users to recognize suspicious files and avoid using external players for Telegram media.
Deploy mobile threat defense solutions to detect anomalous HTML execution attempts.

The resurgence of CVE-2024-7014 via Evilloader underscores the persistent risks of improper input validation in messaging platforms.

As attackers refine their tactics, organizations must adopt layered defenses combining software updates, user awareness, and endpoint monitoring.

Telegram users should immediately verify their app version and exercise caution with unsolicited media files even those appearing as benign videos.
