Three Teens Arrested for Fraudulent AI-Powered Subscriptions to Mobile Company: Why Passwordless Authentication is the Future!

The Incident: How Password-Based Authentication Led to Fraud

Japanese authorities recently arrested three teenagers for fraudulently obtaining Mobile Company subscriptions using illegally acquired IDs and passwords. This incident exposed major security vulnerabilities in traditional password-based authentication systems, highlighting the growing risks of credential stuffing and automated password attacks.

Key Security Issues Identified

Unauthorized Access Due to Password Leaks

• Over 3.3 billion sets of IDs and passwords were seized, with 220,000 appearing in Mobile Company’s login history.
• Attackers obtained login credentials through social media and the dark web.

Automated Password Input via AI Tools

• A custom AI-powered script was developed to systematically try passwords.
• Once successful, it was used to fraudulently register for eSIM services.

Credential Stuffing Attacks

• Single-factor authentication relying on only passwords makes accounts vulnerable.
• Leaked passwords were used to attempt mass logins, leading to unauthorized account access.

This case demonstrates how easily cybercriminals can exploit password-dependent systems, making them an easy target for credential leaks, phishing, and automated attacks.

The Solution: Strengthening Security with AuthFi Passkey

To combat these vulnerabilities, passwordless authentication using FIDO2 security standards is essential. AuthenTrend’s AuthFi Passkey offers a next-generation authentication solution that eliminates passwords and drastically improves security.

How AuthFi Passkey Secures User Authentication

Passwordless Security

• Eliminates the need for passwords, preventing credential leaks.
• Uses biometric authentication (fingerprint, facial recognition) or security keys for login.

Resistance to Credential Stuffing & Phishing

• Authentication credentials (private keys) are stored inside the device, making them impossible to steal.
• Even if attackers acquire login credentials, they cannot log in without the user’s physical device.

Seamless Multi-Device Authentication

• Works across smartphones, PCs, and FIDO2-compatible security keys.
• Supports cross-device authentication (e.g., scanning a QR code on a phone to log in on a PC).

Why Mobile Company Should Implement AuthFi Passkey

A direct comparison between traditional password authentication and AuthFi Passkey clearly shows the benefits:

Authentication Method	Password-Based Login	AuthFi Passkey
Authentication Credentials	ID & Password	Private Key Stored in Device
Risk of Information Leakage	High (Can be leaked or stolen)	Low (Never transmitted externally)
Risk of Unauthorized Login	High (Credential Stuffing, AI Bots)	Impossible (Requires Physical Device)
Phishing Resistance	Low (Password Theft Risk)	High (Public Key Encryption)
Login Complexity	High (Manual Input Required)	Low (Instant Biometric Login)

By integrating AuthFi Passkey, Mobile Company can eliminate unauthorized logins while improving user experience with seamless, secure authentication.

The Impact of Implementing AuthFi Passkey

Eliminates password-related security risks by removing password-based logins.
Neutralizes phishing and credential stuffing attacks, reducing cyber threats.
Enhances user convenience with fast and secure biometric authentication.
Strengthens Mobile Company’s overall security posture, preventing future breaches.

Conclusion: The Future is Passwordless

This case is a wake-up call for telecom providers like Mobile Company to transition from outdated password authentication to modern, passwordless solutions. By adopting AuthenTrend’s AuthFi Passkey, Mobile Company can protect its users, strengthen security, and stay ahead of cybercriminals.
