EDRSandblast and Your End-User Workstations

If your business relies on tools like EDR and antivirus software to protect your end-user workstations, your defenses may not be as strong as you think. Malicious actors and their techniques are constantly evolving, and it’s becoming easier for them to bypass the security systems you already have in place.

What Is “EDRSandblast” and What Does It Do?

EDRSandblast is a sophisticated tool designed to bypass Endpoint Detection and Response (EDR) and antivirus (AV) solutions. It’s an open-source project that has gained attention in the cybersecurity community due to its effectiveness in evading detection.

There are a few ways this tool is able to circumvent AV and EDR security features, including:

• Changing the malware’s code and/or behavior so the security software cannot recognize it.
• Allowing the malware to attack only when the security system isn’t monitoring closely.
• Temporarily weakening or disabling some of the software’s security protections

How Can This Affect Your Business?

The implications of tools like EDRSandblast for businesses are significant:

1. Increased vulnerability: With EDRSandblast, attackers can more easily install malware on your devices, potentially leading to data theft, full-system hijacking, or ransomware attacks.
2. Bypassing existing defenses: Your current security software alone may not be sufficient to protect your data from AV and EDR bypass tools.
3. Stealthy attacks: These techniques allow malware to operate undetected for extended periods, increasing the potential damage.
4. Credential theft: By bypassing LSASS protections, attackers could steal user credentials, leading to further compromise of your systems.
5. Reduced visibility: Disabling EDR callbacks and ETW providers can significantly reduce your security team’s visibility into potential threats.

The Solution

While tools like EDRSandblast pose significant challenges to traditional security measures, staying informed about these threats and adopting a proactive, multi-layered approach to security can help protect your business from sophisticated attacks. Regular security assessments and penetration testing can play a crucial role in identifying and addressing vulnerabilities before they can be exploited by malicious actors.

Your existing security software alone may not be able to protect your data from AV and EDR bypass tools, but that’s where Evangelize Security can help you be proactive about these threats. With Internal Penetration Testing, we can find the areas in your security systems that may be vulnerable to these types of threats.
