GreyNoise researchers observed a 65% drop in global Telnet traffic on January 14, six days before CVE-2026-24061 (a critical root access vulnerability) was publicly disclosed. The sudden traffic decline, affecting specific ISPs while leaving cloud providers unaffected, suggests major transit providers may have received advance warning and implemented port 23 filtering.
