Protecting Your Microsoft SQL Servers: The Rising Threat and How to Counteract It
Microsoft SQL servers are integral components of countless businesses, managing vast amounts of critical data with many of our clients utilising SQL Server for their business software. While there are always attempts to exploit SQL Servers, they have recently become more frequent and targeted by cybercriminals. The latest method, called “DB#JAMMER,” highlights the evolving threat landscape and the hefty ransoms attached. Here’s a deep dive into the rising menace and the steps to ensure your servers remain secure.
Understanding the Threat
Hackers have been sharpening their tools and strategies. Exploiting vulnerabilities in Microsoft SQL servers, they take control, extract sensitive information, and, then lock users out of their own systems. Once they have you locked out, they demand a staggering average ransom of $740,144 according to onmsft (a Microsoft News Site).
Steps in the Attack
- Hackers force their way into the SQL server using a variety of tools to search for unsecured servers.
- They explore the database and execute commands, monitoring the system.
- They weaken the security measures and introduce malicious software, notably the FreeWorld ransomware, effectively locking the system.
Protection Measures
- Utilise strong, frequently changed passwords.
- Activate two-factor authentication on Windows Logins.
- Manage SQL Server Permissions Properly with SQL Server, don’t use the Sys Admin password for all applications.
- Consistently update your SQL Server with the latest patches.
- Set up firewalls to deter unauthorized access.
- Implement systems that detect and counteract malicious activity.
- Backup your data on a regular basis and store backups separately.
- Always have a contingency plan for potential ransomware attacks. The rising ransom amounts emphasize the crucial need for robust security measures for Microsoft SQL servers.
