Juniper Networks | Breach | 100 | 5 | 12/2024 | JUN000122024 | Link | |
Rankiteo Explanation : Attack threatening the organizationโs existenceDescription: Juniper Networks reported an incident on December 11, 2024, where multiple customers experienced suspicious behavior on their Session Smart Network (SSN) platforms. These systems were infected with Mirai malware, which employed the devices in DDoS attacks, causing network disruptions. The malware exploited devices still using default passwords, facilitating unauthorized access and remote command execution. Juniper Networks outlined that signs of Mirai's presence included port scanning, failed SSH logins, spikes in outbound traffic, and erratic behavior. The company recommended enhancing security by changing default credentials, monitoring logs, using firewalls and IDS/IPS, and keeping firmware updated to mitigate the risk of future attacks. | |||||||
Juniper Networks | Breach | 100 | 5 | 3/2025 | JUN000031325 | Link | |
Rankiteo Explanation : Attack threatening the organizationโs existenceDescription: Mandiant researchers discovered custom backdoors deployed by China-linked espionage group UNC3886 on outdated Juniper Networks Junos OS routers. These TINYSHELL-based backdoors aimed for long-term persistence and stealth, targeting internal networking infrastructure and ISP routers. The backdoors imitated legitimate binaries and bypassed Junos OS security mechanisms, which could potentially lead to privileged access abuse, network authentication service compromises, and further covert operations within affected systems. The incident highlights significant vulnerabilities within critical networking devices and represents a strategic threat to the defense, technology, and telecommunications sectors. | |||||||
Juniper Networks | Cyber Attack | 25 | 1 | 12/2024 | JUN000122224 | Link | |
Rankiteo Explanation : Attack without any consequencesDescription: On December 11, 2024, Juniper Networks identified a security breach where multiple customers' Session Smart Router (SSR) products running default passwords were compromised. The attackers leveraged the devices to conduct Distributed Denial-of-Service (DDoS) attacks as part of the Mirai botnet's activity. This security event resulted in unusual network behavior, including port scanning, failed SSH logins, spikes in traffic, and connections from known malicious IP addresses. Juniper Networks has issued recommendations to customers for strengthening security practices and mitigating future risks. This incident underscores the importance of strong password policies and regular security monitoring to prevent exploitation of network devices. No data leaks or critical threats to personal, financial, or regional economic security were reported. | |||||||
Juniper Networks | Ransomware | 60 | 3 | 12/2024 | JUN000122124 | Link | |
Rankiteo Explanation : Attack with significant impact with internal employee data leaksDescription: On December 11, 2024, Juniper Networks reported that a Mirai botnet was targeting Session Smart Router (SSR) products by exploiting devices with default passwords. The malicious actors compromised the SSR devices and used them to launch DDoS attacks against other devices. The systems infected with the Mirai malware displayed signs of unusual activity such as port scanning, failed SSH logins, spikes in outbound traffic, and connections from malevolent IP addresses. Juniper Networks urged customers to bolster security by changing default credentials, using strong passwords, monitoring access logs, utilizing firewalls and IDS/IPS, and updating firmware to mitigate against such threats. | |||||||
Juniper Networks | Vulnerability | 60 | 3 | 12/2024 | JUN000122424 | Link | |
Rankiteo Explanation : Attack with significant impact with internal employee data leaksDescription: Juniper Networks issued an alert regarding a Mirai botnet attack on Session Smart Router (SSR) devices with default credentials. The attack, detected on December 11, 2024, compromised SSR products and facilitated DDoS attacks using the infected devices. The Mirai botnet exploited default passwords to enable remote command execution and initiate various forms of malicious activity, particularly DDoS attacks. Unusual port scans, frequent SSH login failures, traffic spikes, and erratic device behaviors were indicators of the infection. The incident necessitated a reinforcement of security measures, such as updating default credentials, strengthening passwords, regular monitoring of access logs, deployment of firewalls, and up-to-date firmware to mitigate further risks. | |||||||
Juniper Networks | Vulnerability | 100 | 3/2025 | JUN000031625 | Link | ||
Rankiteo Explanation : Attack threatening the organization's existenceDescription: In mid-2024, China-linked cyber espionage group UNC3886 targeted outdated Juniper Networks Junos OS MX routers with custom backdoors. The deployment of TINYSHELL-based backdoors, which allowed for stealthy, persistent access, showed a sophisticated understanding of system internals and posed a significant threat. This attack rendered the organization vulnerable to long-term espionage activities, primarily affecting the defense, technology, and telecommunications sectors in the US and Asia. The security incident not only undermined the integrity of Juniper Networks' devices but also put sensitive customer and employee data at risk. |

What Do We Measure?
Every week, Rankiteo analyzes billions of signals to give organizations a sharper, faster view of emerging risks. With deeper, more actionable intelligence at their fingertips, security teams can outpace threat actors, respond instantly to Zero-Day attacks, and dramatically shrink their risk exposure window.
These are some of the factors we use to calculate the overall score:
Identify exposed access points, detect misconfigured SSL certificates, and uncover vulnerabilities across the network infrastructure.
Gain visibility into the software components used within an organization to detect vulnerabilities, manage risk, and ensure supply chain security.
Monitor and manage all IT assets and their configurations to ensure accurate, real-time visibility across the company's technology environment.
Leverage real-time insights on active threats, malware campaigns, and emerging vulnerabilities to proactively defend against evolving cyberattacks.
