OK. Well-written malware. I get that. But am I the only one who’s surprised that Telnet is still running anywhere at all, and that this is what made the compromise possible in the first place? Sure. It was a honeypot. But the developers of this malware aren’t just targeting honeypots; they’re also after ‘real’ systems. If only someone would develop something like VPNs. https://www.nozominetworks.com/blog/tengu-a-modernized-mirai-that-doesnt-want-to-leave #mirai #malware #wtf #iot #linux #telnet

The Telnet port in 2026 is not a relic. Three simultaneous populations: IoT botnets with hex-encoded auth probes, router scanners with device-specific credential lists, occasional human operators. All three attracted by one honeypot emulating a BusyBox router.

2026-01-14: Il giorno in cui telnet morì Il 14 gennaio 2026, il traffico #telnet globale osservato dai sensori di GreyNoise è crollato. Una riduzione sostenuta del 59%, diciotto ASN completamente silenziosi e cinque paesi completamente scomparsi dai nostri dati. Sei giorni dopo, la CVE-2026-24061 è scomparsa. La coincidenza è una delle possibili spiegazioni. https://www.labs.greynoise.io/grimoire/2026-02-10-telnet-falls-silent/ @informatica

800K Linux servers with a Telnet vulnerability. Unless you need it to talk to some legacy systems, turn Telnet off, it's 2026. https://www.youtube.com/watch?v=81fq__6a1FQ #Telnet #Vulnerability

🚨 Critical #Telnet Authentication Bypass Vulnerability Discovered #CVE202624061 #cybersecurity #infosec #DevOps #security 🔓 #GNU Inetutils telnetd through version 2.7 allows remote authentication bypass via "-f root" USER environment variable ⚡ The exploit is shockingly simple: attackers send "-f root" as the USER value, triggering /usr/bin/login -f root which skips password authentication entirely 🧵 👇
