The Broadside botnet has emerged as a new threat actor targeting the maritime logistics sector, using a command injection vulnerability (CVE-2024-3721) in TBK Vision digital video recorders to compromise devices on vessels. The malware poses significant risks to shipping firms and could have far-reaching consequences for global supply chains and shipping operations.
The Broadside botnet is a Mirai-based threat actor targeting the maritime logistics sector. The malware uses a command injection vulnerability in TBK Vision digital video recorders to compromise devices on vessels. Broadside adapts and evolves to evade detection, suggesting significant sophistication and planning from its creators. The malware employs stealthy monitoring techniques using Netlink kernel sockets to evade detection. Broadside supports UDP-based DDoS attacks and steals critical system credential files for privilege escalation and lateral movement. Compromised devices could enable access to sensitive CCTV feeds, disrupt satellite communications, or provide a foothold for further lateral movement toward critical OT systems on ships. The threat is compounded by the attackers' sophistication and organization, with over 50,000 exposed TBK DVRs identified as potential targets.
In a disturbing turn of events, the cybersecurity landscape has been rocked by the emergence of a new threat actor known as Broadside, a Mirai-based botnet that is specifically targeting the maritime logistics sector. The malware, which has already caused significant concern among shipping companies and vessel operators, is using a command injection vulnerability (CVE-2024-3721) in TBK Vision digital video recorders (DVRs) to compromise devices on vessels.
According to recent reports from Cydome, a cybersecurity research firm, the Broadside botnet campaign has been active for months, with fluctuating activity observed across its infrastructure. This suggests that the malware is not only spreading rapidly but also adapting and evolving to evade detection by security systems.
The Mirai botnet, which was first made public nearly a decade ago, has since become a go-to framework for many cybercriminals seeking to launch large-scale DDoS attacks and other malicious campaigns. However, Broadside differs from its predecessors in several key ways. For example, it uses a custom C2 protocol, unique Magic Header, and "Judge, Jury, and Executioner" exclusivity module, which suggests a level of sophistication and planning that is not typically associated with Mirai variants.
Furthermore, the malware employs stealthy monitoring techniques using Netlink kernel sockets to evade detection. Additionally, Broadside supports UDP-based DDoS attacks but also steals critical system credential files, such as /etc/passwd and /etc/shadow, which enables privilege escalation and lateral movement on compromised devices.
The consequences of this attack are far-reaching and could have significant implications for the maritime logistics sector. Compromised devices could potentially enable access to sensitive CCTV feeds, disrupt satellite communications, or even provide a foothold for further lateral movement toward critical OT systems on ships. This raises serious concerns about the potential for widespread disruption to global supply chains and shipping operations.
The threat of this attack is compounded by the fact that most infections are occurring in countries such as China, India, Egypt, Ukraine, Russia, Turkey, and Brazil, which suggests a level of sophistication and organization among the attackers. While it is difficult to estimate the exact number of infected devices, recent reports from Kaspersky indicate that over 50,000 exposed TBK DVRs have been identified as potential targets.
The Mirai botnet's source code has been made public for several years now, and it has since been widely reused and modified by cybercriminals to power large-scale botnets. However, the emergence of Broadside highlights the ongoing evolution and adaptation of this threat landscape. As such, shipping companies and vessel operators must take immediate action to secure their devices against this new threat.
In conclusion, the emergence of Broadside represents a significant concern for the maritime logistics sector. The malware's sophisticated tactics, stealthy monitoring techniques, and ability to compromise critical systems highlight the need for vigilance and proactive security measures among shipping companies and vessel operators.
