Back to BlogBlumira’s Behavior-Based Detection: A Proactive Approach to Cybersecurity
When it comes to protecting organizations from cyber threats, relying solely on traditional indicator-based tools is no longer enough. Attackers are constantly finding new ways to evade detection, exploiting vulnerabilities before they are even disclosed. This is where Blumira’s behavior-based detection approach shines, providing a proactive solution to the ever-present challenge of cybersecurity.
The Power of Behavior-Based Detection
Blumira’s unique strategy focuses on identifying the actions and techniques associated with different stages of an attack, rather than depending on specific technical artifacts like IP addresses or file hashes. By recognizing patterns across campaigns, Blumira can quickly detect emerging threats, even with limited technical information.
A testament to this approach’s effectiveness is Blumira’s early detection of the MOVEit vulnerability exploitation. On May 28, 2023, three days before the official vulnerability announcement, Blumira alerted its customers to the attack by detecting the attacker’s behavior of writing webshells to establish persistence and control. This proactive detection allowed customers to respond swiftly and minimize the risk of ransomware.
Staying Ahead of Zero-Day Vulnerabilities
Zero-day vulnerabilities, like the one found in MOVEit Transfer, pose a significant challenge for organizations as they are often exploited before official disclosure. Attackers can leverage these vulnerabilities to gain unauthorized access, steal sensitive data, and even deploy ransomware.
In the case of MOVEit Transfer, the Clop ransomware group is suspected to be behind the attacks. This group is known for its “wait-and-see” approach, often waiting weeks after data theft before making extortion demands. By focusing on behaviors rather than specific indicators of compromise, Blumira can detect these attacks early and help organizations stay one step ahead of threat actors.
The Importance of Skilled Detection Engineers
Blumira’s success in detecting threats like the MOVEit exploit can be attributed to the expertise of its skilled detection engineers. These professionals ensure that behavioral analytics have the proper context to identify risky activities without generating excessive false positives.
By combining advanced technology with human expertise, Blumira provides comprehensive protection for its customers. This balance allows organizations to leverage the benefits of automation while maintaining the critical thinking and contextual understanding that human analysts bring to the table.
Empowering Lean Security Teams
Effective risk management requires strong IT and security teams. However, many organizations, particularly small and medium-sized businesses, may not have the resources to maintain a fully-staffed 24/7 security operations center (SOC). Blumira addresses this challenge by focusing on equipping lean teams with scalable technology, enabling them to punch above their weight class in terms of security.
By providing dedicated support through Solutions Architects and a 24/7 Security Operations team, Blumira ensures that its customers have the guidance and expertise they need. This approach allows organizations to grow their internal IT maturity and embrace security across the entire company, reducing overall risk.
The Future of Cybersecurity
By investing in the right people, processes, and technologies, organizations can build resilient security postures that can withstand the ever-changing threat landscape. Blumira’s commitment to innovation and customer success positions the company as a trusted partner in this ongoing battle against cybercrime. Blumira’s behavior-based detection approach, combined with close alignment with internal IT teams, provides a powerful framework for protecting against both known and unknown threats. By focusing on the fundamental actions and objectives underlying attack campaigns, Blumira enables organizations to stay ahead of the curve and protect their critical assets.
