Cybersecurity experts have issued a warning to network administrators as a surge in internet probes targeting devices from major networking companies like Juniper Networks, Cisco Systems, and Palo Alto Networks has been detected. The threat actor behind these probes is specifically targeting Juniper Networks routers using default credentials, sparking concern among experts.
The discovery of this malicious activity has raised alarms within the cybersecurity community, prompting experts to advise network administrators to change the default login credentials on their Juniper Networks routers. According to Johannes Ullrich, dean of research at the SANS Institute, the use of default credentials on such expensive and supposedly secure networking products is concerning in the year 2025.
“It’s concerning that a major networking company like Juniper Networks is still utilizing default username and password combinations in this day and age,” Ullrich stated in a recent interview. The surge in scans for the username “t128” and password “128tRoutes” has been attributed to the threat actor’s attempt to gain unauthorized access to these devices.
The fact that these default credentials are still being targeted by threat actors highlights the importance of password hygiene and the need for organizations to implement strong security measures. Changing default passwords and usernames is a basic security practice that can help prevent unauthorized access to sensitive networks and data.
In light of these recent probes, network administrators are advised to take immediate action to secure their devices and prevent potential cyberattacks. This includes changing default credentials, implementing multi-factor authentication, and regularly updating firmware to patch any known vulnerabilities.
The use of default credentials is a common issue that continues to pose a significant security risk for organizations worldwide. As cyber threats evolve and become more sophisticated, it is crucial for network administrators to stay vigilant and proactive in securing their infrastructure.
Overall, the surge in internet probes targeting devices from Juniper Networks, Cisco Systems, and Palo Alto Networks serves as a stark reminder of the importance of cybersecurity hygiene and the need for organizations to prioritize security measures to protect against potential threats. By taking proactive steps to enhance their security posture, organizations can better defend against malicious actors and safeguard their networks from cyberattacks.
