Spanish Hacker Uses Stolen Credentials and Social Engineering to Breach Government Networks

José Luis Huertas exploited weak access controls by using a stolen digital certificate from Spain's traffic agency to breach critical government networks including SARA and the Neutral Judicial Point. He then created phishing pages to harvest court workers' credentials, demonstrating how social engineering can bypass technical security measures. This case highlights the devastating impact when privileged access credentials are compromised, allowing attackers to access sensitive banking records of over 500,000 citizens. The incident shows how attackers combine technical exploitation with human manipulation to maximize their access to valuable data.
