Mirai Campaign Exploits RCE in EoL D-Link DIR-823X Routers
🔒 A new Mirai-based campaign is actively exploiting CVE-2025-29635, a command-injection RCE that affects D-Link DIR-823X routers, to enlist devices into a botnet. Akamai's SIRT observed the activity in March 2026 and found attackers downloading and executing a shell script that installs a multi-architecture Mirai variant called tuxnokill. The affected DIR-823X line reached end of life in November 2024 and is unlikely to receive a vendor patch. Users are advised to replace EoL devices, disable remote administration, change default passwords, and monitor for configuration changes.
