New Mirai botnet infect TBK DVR devices via command injection flaw Source: https://www.bleepingcomputer.com/news/security/new-mirai-botnet-infect-tbk-dvr-devices-via-command-injection-flaw/
Impact
For European organizations, the infection of TBK DVR devices by this Mirai variant poses several risks. Many businesses and public institutions use DVRs for surveillance and security monitoring, and compromised devices could lead to unauthorized access or manipulation of video feeds, undermining physical security. Additionally, infected devices contribute to the botnet's overall capacity to launch large-scale DDoS attacks, which could target European infrastructure, government services, or private enterprises, causing service disruptions and financial losses. The command injection flaw could also be leveraged to pivot into internal networks if DVRs are connected to corporate LANs, potentially exposing sensitive data or critical systems. The widespread use of IoT and surveillance devices in Europe, combined with varying levels of cybersecurity maturity among organizations, increases the likelihood of successful exploitation. Moreover, the lack of patches and the difficulty in updating embedded devices like DVRs mean that many vulnerable devices may remain in operation for long periods, sustaining the botnet's growth and threat persistence.
Defensive guidance
European organizations should immediately inventory all TBK DVR devices within their networks and assess their exposure to the internet. Network segmentation should be enforced to isolate DVR devices from critical infrastructure and sensitive data environments. Implement strict firewall rules to restrict inbound and outbound traffic to and from these devices, limiting communication to trusted sources only. Where possible, disable remote management interfaces or change default credentials to strong, unique passwords. Monitor network traffic for unusual patterns indicative of botnet activity, such as unexpected outbound connections or command and control communications. Since no patches are currently available, organizations should consider replacing vulnerable devices with models from vendors that provide timely security updates and support. Additionally, deploying intrusion detection/prevention systems (IDS/IPS) with signatures for Mirai-related traffic can help detect and block attempts to exploit the command injection flaw. Regularly updating network device firmware and maintaining an up-to-date asset inventory will improve overall security posture against similar threats.
