Were telcos tipped off to *that* ancient Telnet bug? Cyber pros say the signs stack up

: Curious port filtering and traffic patterns suggest advisories weren’t the earliest warning signals sent

The Register
port 23 filtering: A whole port becomes hard to use on the Internet as a clumsy mitigation of a bug in telnetd, an obsolete protocol

2026-01-14: The Day the telnet Died – GreyNoise Labs

On January 14, 2026, global telnet traffic observed by GreyNoise sensors fell off a cliff. A 59% sustained reduction, eighteen ASNs going completely silent, five countries vanishing from our data entirely. Six days later, CVE-2026-24061 dropped. Coincidence is one explanation.

Make sure you patch your OS on security level. Don't chase uptimes on machines facing the internet. We did that in the 80's and 90's. Back then we even used telnet over the internet. Strangers could trust eachother,

Times have changed

Is it possible to run the telnet service on OpenBSD 7.5? I've done quite a bit of research and it appears that it's been removed. If you're kind enough to reply, please do so without the telnet is insecure, and why do you want to do that response. #OpenBSD #telnet #service #port23

TFW you're poking around the high ports and you find a #telnet #root #shell left in up there. A good payoff from a little mischievous exploration.
