ClingSTUN Backdoor Exploits Multiple IoT Vulnerabilities to Gain Persistent Remote Access

ClingSTUN is a Linux backdoor that exploits vulnerable internet-connected devices to give attackers lasting remote access. Rather than simply infecting routers and cameras, it turns compromised equipment into remotely controlled proxy nodes that can relay traffic and run commands. The campaign targets known security flaws across multiple vendors, expanding its attack methods as it evolves. Unpatched firmware, unsupported hardware, and exposed services create openings for infections that can survive device restarts and conceal their activity from routine checks. Fortinet researchers identified three stages of the campaign, each using a different download source. Fortinet said in a report shared with Cyber Security News (CSN)...
