Routers are network gateways whose flaws, misconfigurations, or exposed interfaces can enable unauthorized access, interception, or service disruption.

Background for this topic.
Routers are network devices that forward packets between separate networks, using destination addresses to choose a path. A home router usually connects a local network to the internet and may also provide wireless access, address assignment, network address translation, firewall rules, VPN termination, or DNS forwarding. Enterprise routers can connect internal segments, data centers, and remote sites.
In security, a router is both a traffic-control point and an attack surface. Vulnerable firmware, exposed administrative services, weak credentials, or unnecessary remote management can let an attacker alter routing, redirect traffic, or use the device to reach other systems; misconfigured rules can expose internal services. Reduce risk by keeping firmware supported and updated, restricting management to trusted networks, using strong unique authentication, disabling unneeded services, separating networks, and reviewing logs and configurations. During an incident, router configuration and routing or DNS changes can provide useful evidence, while tested backups help restore trusted connectivity.
A high-severity flaw impacting select Four-Faith routers has come under active exploitation in the wild, according to new findings from VulnCheck
Mirari and Kaiten Botnet Variants Exploit Unpatched RoutersAttackers exploiting nearly decade-old D-Link router vulnerabilities drove a sharp rise in botnet activity in 2024 through variants of the Mirari and Kaiten taking advantage of unpatched devices. Operators of botnets known as Ficora and Capsaicin exploit nearly decade-old flaws.
Cybersecurity researchers are warning about a spike in malicious activity that involves roping vulnerable D-Link routers into two different botnets, a Mirai variant dubbed FICORA and a Kaiten (aka Tsunami) variant called CAPSAICIN
A new Mirai-based malware campaign is actively exploiting unpatched vulnerabilities in Internet of Things (IoT) devices, including DigiEver DS-2105 Pro DVRs. [...]
Major Chinese Router Manufacturer Facing Increased Scrutiny After Chinese EspionageU.S. authorities have launched multiple investigations while reportedly considering banning the widely popular Chinese-manufactured TP-Link routers amid ongoing security risks linked to Chinese cyberespionage and hacking campaigns targeting American critical infrastructure sectors.
