• Malware and trojans: Repackaging an APK enables insertion of malicious code (credential harvesters, backdoors, remote access tools). Mod APKs from untrusted sources pose high risk.
• Credential theft: Modified apps can capture login tokens, credentials, or 2FA codes; using them with your primary Facebook account risks account compromise.
• Data exfiltration: Mods may silently collect contacts, messages, device identifiers, or other sensitive data and transmit it to third parties.
• Signature & update problems: Re-signed APKs can’t receive updates from Google Play; users must trust third-party sites for updates, increasing exposure to tampered files.
• Account bans: Facebook’s terms forbid modified clients in many cases; using a mod can trigger enforcement actions including temporary or permanent bans.
• Broken security features: Mods that disable certificate pinning, tamper with encryption layers, or alter login flows can weaken protections and enable man-in-the-middle attacks.
