Les dejo disponible a todos un curso de redes nivel #CCNA gratuito en español de casi 100 horas que acabo de publicar. Este curso estuvo mucho tiempo en otra plataforma y por fin pude recuperar el material y subirlo a YouTube. Espero que lo disfruten: youtube.com/playlist?list=…

Over the past 48 hours there have been some very interesting developments... The "@chartercomms" announcements for 47.1.0.0/16 and 47.2.0.0/16 have disappeared, implicitly confirming that they were hijacked. The "@Orange" announcement for AS41128 has changed - the path is now: 90.98.0.0/15 AS41128 AS22541 AS29802 AS41128: @orange 🇫🇷 AS22541: MEGALINK S.R.L.🇧🇴 AS29802: @HIVELOCITY 🇺🇸 The entire network has relocated from Chicago to Dallas (likely to the Prime Dallas Campus DFW01 datacenter). Once more the inclusion of a South-American ISP appears completely unrealistic, with the traffic between the AS29802 router (de-cix[.]dfw[.]hivelocity[.]net) and the final destination seemingly within the Dallas datacenter. But there's more....⬇️

@precisox Jamás jugaría a esto en mi tiempo libre. Suficiente estar todo el día lidiando con problemas de datacenters y conectividad reales. Prefiero ir a andar en bicicleta o hacer un asado

Alguien ha creado el juego más adictivo para aprender redes de centros de datos. Esta increíblee! Se llama Data Center; cuesta 6 dólares y empiezas con el suelo completamente vacío: compras racks, montas servidores y tiendes cada cable a mano. Lo más brutal es que el tráfico de cada cliente se visualiza como esferas de colores que circulan por tus cables, literalmente ves los cuellos de botella en tiempo real. 190 reseñas en 48 horas, gente con equipos equipados con tarjetas RTX 4090 está totalmente enganchada y divirtiéndose en un simulador de cableado de 6 dólares.

@Vincentt1987 Nos pasó una vez con un colega. Optamos por ponerle como sobrenombre "Pijama" (de León).

¿Es esta la mejor manera de decirle a un compañero de trabajo que tiene mal olor corporal?

🚨 New Fortinet vulnerability being exploited as an 0-day CVE-2026-35616 - FortiClient EMS pre-authentication API access bypass - CVSS 9.1 Critical After observing in-the-wild exploitation of this vulnerability earlier this week, Defused reported it to Fortinet under responsible disclosure. Fortinet has released an emergency hotfix - plus a scheduled patch - for FortiClient EMS 7.4.5 and 7.4.6. The vulnerability allows an unauthenticated attacker to bypass API authentication and authorization entirely, unauthorized code or commands via crafted requests. This discovery was made through our upcoming Radar feature launching next week 😇 Advisory: fortiguard.com/psirt/FG-IR-26… Track exploitation of this and other Fortinet vulns in real time and get updates on the new Defused Radar 👉 console.defusedcyber.com/signup Credit also to @heckintosh_ for independently discovering this vulnerability 💪

🚨 CRITICAL: Active supply chain attack on axios -- one of npm's most depended-on packages. The latest axios@1.14.1 now pulls in plain-crypto-js@4.2.1, a package that did not exist before today. This is a live compromise. This is textbook supply chain installer malware. axios has 100M+ weekly downloads. Every npm install pulling the latest version is potentially compromised right now. Socket AI analysis confirms this is malware. plain-crypto-js is an obfuscated dropper/loader that: • Deobfuscates embedded payloads and operational strings at runtime • Dynamically loads fs, os, and execSync to evade static analysis • Executes decoded shell commands • Stages and copies payload files into OS temp and Windows ProgramData directories • Deletes and renames artifacts post-execution to destroy forensic evidence If you use axios, pin your version immediately and audit your lockfiles. Do not upgrade.

Es que no hay comparación.

@uBF2fV1cVQxRjQo I am pretty sure that planet still uses CRT vacuum technology. Soon they will discover LED and create more optimized space portals.
