Millions of User Accounts Potentially Exposed as SMS Routing Company Leaves Database Unsecured
Millions of users of popular platforms like Facebook, Google, TikTok, and WhatsApp may have had their accounts compromised due to a security lapse by an SMS routing company. The company, YX International, left an internal database containing sensitive information, including two-factor authentication (2FA) codes and password reset links, exposed on the internet without a password.
How did this happen? YX International, which processes millions of SMS messages daily, failed to secure one of its internal databases. This meant anyone with the database's IP address could access it using a simple web browser. Security researcher Anurag Sen discovered the exposed database and reported it to TechCrunch, which helped identify the owner and bring the issue to light.
What information was exposed? The database contained the contents of text messages sent to users, including:
- Two-factor authentication (2FA) codes: These temporary codes are used as an extra layer of security during login attempts.
- Password reset links: These links allow users to reset their passwords if they forget them.
The good news is that these codes and links typically expire within minutes, making them less valuable to potential attackers. However, the incident highlights the risks associated with SMS-based 2FA. SMS messages are inherently insecure and can be intercepted or compromised.
What should you do? While the immediate risk from the exposed database is likely low, it's still a good idea to take steps to improve your account security:
- Enable stronger forms of 2FA: If available, consider using an authentication app or a physical security key instead of SMS-based 2FA. These methods are generally more secure than SMS.
- Be cautious of suspicious links: Don't click on links in emails or text messages from unknown senders, even if they appear to be from legitimate companies.
- Use strong passwords: Create unique and complex passwords for all your online accounts. Consider using a password manager to help you create and store strong passwords.
This incident serves as a reminder of the importance of cybersecurity vigilance. Companies have a responsibility to protect user data, and users need to be proactive in safeguarding their accounts. By taking steps to improve your online security, you can help minimise the risk of falling victim to cyberattacks.

It's also a reminder to users to be vigilant about their online security and take steps to protect their accounts. By using strong passwords, enabling two-factor authentication, and being cautious of suspicious links, you can help keep your accounts safe from unauthorized access.
