The Health Sector Cybersecurity Coordination Center (HC3) has recently identified a cyber threat to the healthcare sector: Godzilla Webshell.
What is the Godzilla Webshell?
The Godzilla Webshell is a malware tool used by attackers to gain persistent access to compromised systems. Once deployed, it allows the attacker to:
Modify files
Run remote commands
Maintain access for extended periods without detection
Godzilla is especially hazardous due to its use of AES encryption, which enables it to remain unnoticed by traditional security systems. Once established on a server or system, the webshell grants the attacker significant control over the environment.
Who is Using Godzilla, and Why?
This malware has been linked to Chinese cyber espionage groups, such as DEV-0322 and APT Dalbit. These groups have targeted a broad range of industries, with healthcare being a notable focus due to its wealth of patient records and proprietary data.
Godzilla is attributed to an entity known as BeichenDream, and troublingly, it is publicly available, allowing a wide range of attackers to adopt and customize it for their malicious purposes.
Recent Cyber Incidents Involving Godzilla
Recent incidents reveal how threat actors have exploited vulnerabilities in popular software, including ManageEngine ADSelfService Plus, to launch attacks using Godzilla. These campaigns have specifically targeted healthcare organizations, compromising sensitive data and threatening the integrity of their operations.
Additionally, the integration of Godzilla into attack frameworks allows threat actors to target supply chains, further increasing the scope and potency of the malware in strategic, multi-layered attacks.
Mitigating the Risks Posed by Godzilla
Given the stealth and persistence of the Godzilla Webshell, organizations must adopt comprehensive security measures to detect and neutralize the threat. Following best practices from cybersecurity authorities such as the Cybersecurity and Infrastructure Security Agency (CISA) is essential.
Key actions include:
Regularly update your software: Keeping systems and applications up to date is critical to preventing attackers from exploiting known vulnerabilities.
Monitor system activity: Use advanced monitoring tools to detect any suspicious or unauthorized remote command executions.
Strengthen web application security: Implement Web Application Firewalls (WAFs) and ensure that robust security controls are in place to protect against common web-based attacks.
Additionally, incident response planning should be a priority, enabling swift actions in the event that Godzilla or any other webshell is detected.
Web Server Safeguard (WSS): Protect Your Web Servers in Real-Time
While taking preventative actions is crucial, having a solution that continuously monitors and responds in real-time to evolving threats is equally important. This is where UMV Inc.'s flagship product, Web Server Safeguard (WSS), comes in.
WSS is designed specifically to combat webshells like Godzilla. Its cutting-edge technology provides:
Continuous, real-time web shell detection
Instant alerts when a webshell is detected
Automated response mechanisms to neutralize threats before they can cause harm
Adaptive monitoring that evolves with emerging webshell threats
By integrating WSS into your security infrastructure, you gain an additional, powerful layer of defense. With multi-layered detection capabilities, your organization can detect and block even well-hidden and encrypted webshells like Godzilla.
Healthcare organizations and others dealing with sensitive data can dramatically reduce their risk of falling victim to webshell-based attacks, ensuring that their systems remain secure, compliant, and operational.
Take the Next Step in Securing Your Web Infrastructure
Don’t wait until it’s too late. With cyberattacks growing more sophisticated by the day, ensuring robust defenses like Web Server Safeguard (WSS) is essential to keeping your systems secure.
