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.

The pattern points toward one or more North American Tier 1 transit providers implementing port 23 filtering

The exploitation of this issue is so ridiculously trivial, I'm shocked it took 11 years to discover

To be fair, Telnet was already mostly dead in 2015.

Yeah at least, it died with the rise of encryption
