Mirai Botnet Exploits D-Link Router Vulnerability CVE-2025-29635
In March 2026, Akamai's Security Intelligence and Response Team (SIRT) identified active exploitation of CVE-2025-29635, a command injection vulnerability in D-Link DIR-823X routers, by a new Mirai-based malware campaign. Attackers are sending POST requests to the vulnerable endpoint, executing remote commands to download and install a Mirai variant named "tuxnokill," which enables the compromised devices to perform distributed denial-of-service (DDoS) attacks. This marks the first observed in-the-wild exploitation of this vulnerability since its disclosure in March 2025.

The resurgence of Mirai variants targeting unpatched IoT devices highlights the ongoing threat posed by botnets leveraging known vulnerabilities.
