AryStinger Malware Infects 4,300 Legacy Routers to Build Reconnaissance Proxy Network
A new malware family is turning forgotten home routers into a distributed reconnaissance and proxy network, not the DDoS botnet these devices usually end up in. QiAnXin's XLab  calls it AryStinger and counts at least 4,300 infected routers, a total it says is still rising. The distinction matters. AryStinger exists for the stage of an attack that comes before the break-in. Infected devices scan the internet, fingerprint services, enumerate subdomains, tunnel traffic, and run commands on demand, then ship the results back to the operator. Each router becomes a footprinting node and a relay that hides where the real attacker is. Old chips, older bugs The campaign goes after routers built on Realtek's RTL819X chips, hardware that was current around 2012 to 2015. XLab first saw it on March 12, 2026, spreading from a single IP, 107.150.106.14. The binary it pushed was a Linux ELF that no engine on VirusTotal flagged, exploiting two flaws from another era: CVE-2013-3307 ...
