A Vulnerability That Could Have Destroyed a Company's Reputation: How A42 Averted Disaster

Recently, we discovered one of those vulnerabilities that could have turned into a real nightmare for a company. Using our innovative tool on the A42 platform, we came across an API route within a large network of websites with a total monthly traffic of 30 million users. This API allowed emails to be sent from the corporate mail server to any address without authentication, with any subject and content.

❗ What does this mean?

This isn't just open access to sending emails. Malicious actors could have exploited this vulnerability to:            

🎣 Launch phishing attacks on behalf of the company.            
📩 Conduct mass spam campaigns, which could have destroyed the organization's reputation.            
💰 Cause potential financial losses and result in the company’s email services being blocked.          

🛠 How did we detect this?

Our tool works similarly to Google. It automatically scans web pages, identifying potential threats and attack vectors that hackers might use. During a routine scan, we found an open API route that allowed emails to be sent from the corporate domain without any authorization.           

✅ What was done?

After identifying the issue, we immediately informed the company, and fortunately, they responded quickly. No serious consequences occurred, but this situation highlights the importance of using tools for automated vulnerability detection.

🧠 Key Takeaways:

This is yet another example of how our platform can promptly detect critical threats before they become a problem. Our innovative approach allows us to quickly identify and fix vulnerabilities, reducing risks for large organizations.            

Together, we're making the internet a safer place!
