Unveiling Vulnerabilities: GreyNoise Intelligence Discovers Critical Flaws in Live-Streaming Cameras

In an alarming revelation, cybersecurity firm GreyNoise Intelligence has identified two significant security vulnerabilities in live-streaming cameras widely used across various sectors, including industrial operations and healthcare. These vulnerabilities could potentially allow malicious actors to gain complete control over Internet of Things (IoT) devices, raising serious concerns about the security of critical infrastructure and personal privacy.

The Discovery of Zero-Day Vulnerabilities

The discovery of these vulnerabilities, tracked as CVE-2024-8956 and CVE-2024-8957, was made after an attacker attempted to exploit the vendor’s Sift honeypot. This honeypot, designed to attract and analyze malicious traffic, revealed that a hacker had developed an automated zero-day exploit targeting IoT devices, including the vulnerable cameras.

GreyNoise’s report highlights a groundbreaking aspect of this discovery: the vulnerabilities were detected using an internal and proprietary AI technology. The researchers noted, “This marks one of the first instances where threat detection has been augmented by AI to discover zero-day vulnerabilities.” By identifying malicious traffic that traditional tools might overlook, GreyNoise was able to intercept the attack and report the vulnerabilities before they could be exploited on a larger scale.

AI-Powered Threat Detection

At the heart of GreyNoise’s detection capabilities is its Sift honeypot, which utilizes large language models (LLMs) trained on vast amounts of internet traffic. This advanced AI system can identify anomalies in traffic patterns that conventional systems may miss. By analyzing real-time data and leveraging proprietary datasets, Sift effectively separates routine internet activity from potential threats, allowing human researchers to focus on genuine risks.

In this instance, Sift flagged unusual traffic that had not been previously categorized as a threat. This anomaly caught the attention of GreyNoise researchers, leading to a deeper investigation that ultimately uncovered the two zero-day vulnerabilities in live-streaming cameras.

The Implications of Complete Device Takeover

The vulnerabilities identified by GreyNoise pose severe risks. Threat actors exploiting these flaws could gain complete control over the cameras, allowing them to view or manipulate video feeds, disable camera operations, and even incorporate the devices into larger botnets for launching denial-of-service (DoS) attacks.

The researchers indicated that the vulnerabilities could affect NDI-enabled pan-tilt-zoom cameras from various manufacturers. These cameras, which feature embedded web servers accessible via web browsers, are often deployed in environments where reliability and privacy are paramount, such as industrial plants, healthcare facilities, business conferencing rooms, courtrooms, and places of worship.

Understanding the Vulnerabilities: Inadequate Authentication and Command Injection

The first vulnerability, CVE-2024-8956, carries a severity rating of 9.1 out of 10 and exploits inadequate authentication mechanisms. This flaw could allow attackers to access sensitive information, including usernames, MD5 password hashes, and configuration data. Given that MD5 hashes are known to be insecure, hackers who successfully crack them could gain administrative access to the devices.

The second vulnerability, CVE-2024-8957, has a severity rating of 7.2 and enables attackers to execute arbitrary operating system commands, granting them full control over the cameras. By combining these two vulnerabilities, an attacker could extract critical network details, such as IP addresses and MAC addresses, potentially facilitating lateral movement within the device’s local network. This could lead to broader data breaches or even the deployment of ransomware across connected systems.

The Growing Security Challenge of IoT Devices

The discovery of these vulnerabilities underscores the escalating security challenges posed by the rapidly expanding IoT landscape, which is projected to encompass 32.1 billion devices by 2030. With approximately 18 billion IoT devices in operation this year alone, the sheer volume of data generated complicates the task of distinguishing genuine threats from routine network traffic, leaving systems vulnerable to sophisticated attacks.

The FBI recently dismantled a botnet operated by the Chinese threat group Flax Typhoon, which comprised around 200,000 IoT devices, including routers and network-attached storage. This botnet was used to target critical infrastructure operations, corporations, and government agencies in the United States and beyond, highlighting the urgent need for enhanced security measures in the IoT space.

The Role of AI in Cybersecurity

The ability of GreyNoise’s AI-driven tool to detect these vulnerabilities illustrates the critical role that emerging technologies will play in combating the rising tide of cyber threats. As Andrew Morris, founder and chief architect at GreyNoise, noted, AI can dramatically accelerate the discovery of vulnerabilities, making the internet a safer place, one discovery at a time.

In conclusion, the identification of these vulnerabilities in live-streaming cameras serves as a stark reminder of the security challenges facing the IoT ecosystem. As the number of connected devices continues to grow, so too does the need for innovative solutions that leverage AI and advanced analytics to protect against evolving cyber threats. The proactive approach taken by GreyNoise not only highlights the potential of AI in cybersecurity but also emphasizes the importance of vigilance in safeguarding critical infrastructure and personal privacy in an increasingly interconnected world.
