In this paper, we extend our previous analysis by presenting a long-term investigation of MikroTik-targeted attacks. Despite their popularity, these devices are known to have numerous vulnerabilities. We have shown that these devices are also popular in Internet Exchange infrastructures. ![]() ![]() In our previous research, we found more than 4 million MikroTik routers available on the internet. MikroTik is a particular brand of low-cost router. Routers of the type concerned are used both to provide last-mile access for home users and to manage interdomain routing (BGP). In recent years, malware such as VPNFilter, Navidade, and SonarDNS has been used to compromise low-cost routers and commit all sorts of cybercrimes from DDoS attacks to ransomware deployments. An attack targeting such devices can affect an entire autonomous system. Attacks targeting network infrastructure devices pose a threat to the security of the internet.
