Advanced Threat Protection: Leveraging Censys with RavenTek Expertise

How to best protect your organization from current cybersecurity exploitations.

Recent reports from various cybersecurity outlets including Bleeping Computer, CISA, and Cybersecurity News have highlighted the critical issue surrounding Cisco zero-day vulnerabilities that have been exploited by a state-sponsored hacking group known as UAT4356, or STORM-1849. These vulnerabilities were exploited in a campaign dubbed ArcaneDoor, targeting government networks across the globe. The exploited vulnerabilities in Cisco’s Adaptive Security Appliance (ASA) and Firepower Threat Defense (FTD) firewalls, identified as CVE-2024-20353 and CVE-2024-20359, allowed attackers to gain unauthorized access, disable logging, execute arbitrary code, and exfiltrate data.

Two specific pieces of malware, Line Dancer and Line Runner, were used to maintain persistence and facilitate espionage. Cisco Talos Intelligence and other security entities have been instrumental in identifying and mitigating these threats, but the initial attack vector remains unclear. Cisco has since released security updates to address these vulnerabilities and has strongly urged all users to upgrade their devices to prevent further exploitations.

Advanced Threat Protection with Censys & RavenTek

In response to these incidents, the Censys internet intelligence platform offers a comprehensive solution for identifying and cataloging public-facing assets within an organization’s network that can provide advanced threat protection. This platform extends beyond mere detection, mapping out an organization’s entire digital presence, which includes both traditional on-premise systems and the transient nature of cloud-hosted services. Leveraging this robust platform means organizations are not only aware of their digital assets but are also capable of monitoring their network for any changes, assessing risks with greater accuracy, and thereby enhancing their overall security posture.

At the core of Censys asset management services is a suite of tools designed to illuminate and clarify the assets your organization presents to the world. This illumination is critical not only for recognizing systems that may be susceptible to known vulnerabilities but also for grasping the broader risk landscape associated with external facing assets. These tools delve into the specifics, determining what software is operational on these assets, the variety of ports and protocols that are exposed, and importantly, it doesn’t stop there. Censys extends their services to provide remediation recommendations, ensuring that your organization is not just aware of its exposure but is also equipped with the knowledge to strengthen and fortify its defenses. This strategic approach is integral for prioritizing security efforts where they are most needed, safeguarding the most critical and vulnerable segments of your infrastructure.

Given the severity of the situation, it is a critical time for organizations using Cisco devices to ensure they are applying the latest patches and following best practices for network security. Regular audits of system logs, the implementation of multi-factor authentication, and active monitoring for unscheduled reboots or unauthorized configuration changes are recommended.

For enhanced network resilience and proactive defense, advanced threat protection from Censys can help your organization scan, analyze, and understand your public internet-facing assets to prevent infiltration through known vulnerabilities. Incorporating this into your cybersecurity strategy can augment your preparedness against such sophisticated cyber-espionage campaigns.
