Antenas de radiotelescopio al anochecer: la adolescencia tecnológica de la humanidad según el ensayo de Dario Amodei

The adolescence of technology: reading Dario Amodei's essay with our hands in the mud

In January 2026 the CEO of Anthropic published a twenty-two-thousand-word essay on the five risks of powerful AI and on whether we are ready for them. His answer is no. We read the whole thing from inside a company that deploys automation and AI on real infrastructure: the five risks laid out, an honest scorecard, the four points where we do not buy his argument — including one almost nobody has reported correctly — and what a company that does not build models should be doing today.

Controladores de gestión BMC expuestos en internet: 36.872 servicios IPMI accesibles por UDP 623
9 min read

There is another computer inside your server, and 36,872 of them are on the internet

A scan published on 29 July 2026 found 36,872 management controllers (BMCs) listening on the internet over UDP/623, and 24,650 of them hand out material derived from the account password before anyone logs in. This is not a new CVE: it is CVE-2013-4786, a flaw in the IPMI 2.0 specification itself, dating from 2004, which Dell acknowledges has no patch. The numbers, why a factory password falls in between 32 seconds and one hour, why your EDR will not see it and the six steps to close the management plane of your hardware.

Zabbix 8.0: análisis de qué cambia de verdad en la próxima LTS de monitorización

Zabbix 8.0: what actually changes and what is still a slide

Zabbix 8.0 is the next LTS and half the industry already writes about it as if it were installed. As of 30 July 2026 the latest published artefact is beta 2, dated 9 July, and in the official container registry 8.0 is called trunk. Which features are really in the official release notes (native JSON up to 128 MiB, ClickHouse as a history backend, c-ares with DNS caching), what is still only roadmap (OpenTelemetry, complex event processing, mobile app, proxy permissions) and where the real bill for the upgrade sits: the database minimums and the removed macros living inside your alerts.

La subida de precios de Microsoft 365 del 1 de julio de 2026, con la cuenta real por usuario

Microsoft 365 has already gone up: the percentage that scares you is not the one that costs you money

On 1 July the price increase for Microsoft 365 commercial suites came into force. Through June everyone repeated the same advice —renew before the 1st and you freeze your price— and that advice expired four weeks ago. The official before-and-after price table, the math that actually matters (per-user increase multiplied by headcount and by twelve), why the price that does NOT change is the most informative figure in the announcement, which capabilities land in each suite, and the five things we would do before your renewal.

Proxmox VE 8 llega a su fin de soporte en agosto de 2026

Proxmox VE 8 runs out of patches in August: why we won't upgrade on the 30th

The lifecycle table in Proxmox's official documentation puts the end of life of the 8 branch in August 2026. Just over thirty days are left, and the typical reaction is to block out a weekend and jump to 9. Our stance is the opposite: there are six situations where upgrading this August is a worse idea than being late. The live-migration asymmetry that turns your rollback into a restore, why Ceph means two windows and not one, the containers with old systemd that will not start, and a realistic split of the thirty days left.

NIS2 en España: la ley sin publicar y el cuestionario de proveedor que ya está en tu correo

NIS2 in Spain: the law is not here yet, your customer's questionnaire is

As of 29 July 2026 the Spanish law transposing NIS2 still has not been published in the official gazette: the text was approved by the Council of Ministers in January 2025 at first reading and is still a draft bill, and on 8 July the European Commission decided to refer Spain to the Court of Justice of the EU asking for penalties. That does not mean NIS2 is not affecting you: it means it will not arrive via an inspector, but via your largest customer's procurement department. What already applies today with no transposition needed, what those supplier questionnaires really ask, and what we would do with ninety days ahead of us.

CVE-2025-68686: el parche de FortiOS que se saltaba con una barra de más
8 min read

Patching is not cleaning: FortiOS and the extra slash

On 27 July, CISA added a FortiOS flaw to its exploited-vulnerabilities catalogue with a deadline attached: 10 August. CVE-2025-68686 opens no new door: it reopens the one Fortinet believed it had closed in April 2025, and it does so with one extra slash in the path. The story of the symbolic link in the language-files folder, the patch that was a string comparison, the 7.2, 7.0 and 6.4 branches left with no fix at all, and why patching is an action while being clean is a conclusion you have to prove.

Fatiga de alertas: cómo montar una monitorización que avisa de lo que importa
8 min read

Your monitoring is not broken: it is shouting

An organisation receives an average of 2,992 security alerts a day and 63% of them go unaddressed, according to Vectra AI's 2026 count. The interesting part is that the volume has been falling for three years and the unaddressed share has not moved. Filtering harder does not fix it, because the problem was never how many alerts arrive: it is how many arrived with an owner and an action written next to them. How we prune monitoring that shouts, what wakes us at three in the morning, and what waits for the morning report.

Proxmox joins NVIDIA's ecosystem: a logo will not migrate your infrastructure

Today Proxmox Server Solutions announced it is joining the NVIDIA Mission Control ecosystem: Proxmox VE as the virtualisation and high-availability layer beneath the management services of AI factories, with engineering work for the Grace and Vera CPUs. What the announcement actually says, where Proxmox sits in that picture and where it does not, and why an announcement changes the conversation in a boardroom but changes none of the things that decide your migration.

CVE-2026-16812 en el VeloCloud Orchestrator: el orquestador SD-WAN expuesto por diseño
7 min read

Your WAN orchestrator is on the internet by design: VeloCloud's 10.0

CVE-2026-16812 is an unauthenticated command injection in the on-premises VeloCloud Orchestrator: CVSS 10.0, exploited before a patch existed, and in CISA's KEV catalogue the same day with three days to fix it. Arista's advisory says the console is exposed by default and that no configuration prevents that exposure; a few lines further down it recommends restricting access to the web interface to trusted administrative networks. Both are true, and the bad day is decided in the distance between them.

CVE-2026-14266 en 7-Zip: por qué en la mayoría de los PCs de empresa el mejor parche es desinstalarlo
6 min read

The best patch for 7-Zip is uninstalling it (on most of your PCs)

CVE-2026-14266 is a heap overflow in 7-Zip's XZ decoder: it affects version 21.07 and every release up to 26.01. With no public exploit and no known exploitation, it is not an emergency. But that is two code-execution flaws in two months, the program updates by hand, and Windows 11 has opened .7z and .rar natively since 2023. Before updating two hundred machines, it is worth checking how many actually need it.

AI took the RAM: what to do with your 2026 hardware plan

TrendForce forecast second-quarter contract price rises of 58% to 63% for conventional DRAM and 70% to 75% for NAND. In one quarter, with nothing inside your company to explain it. Why the big cloud providers are hedged by multi-year contracts and you are not, how this lands in your refresh plan, what to check before signing a purchase order, and how long it lasts — with dates.

Despliegues reproducibles con Docker Swarm y GitOps: latest no es una versión

"latest" is not a version: three lessons from deploying our own website with Docker Swarm

The pipeline went green, the webhook returned 200, and the site kept serving the old content. Three real lessons from our GitOps CI/CD on Docker Swarm: why the orchestrator does not chase your tag and what it takes for a redeploy to actually redeploy, why a linter is not a test (and the smoke test that saved our blog index), and the "zero downtime" our own file claimed but never delivered with a single replica.

Cl0p didn't encrypt a single file: extortion walks in through the app nobody watches

Cl0p is exploiting a critical vulnerability in PTC Windchill and FlexPLM (CVE-2026-12569, CVSS 9.3) to steal engineering data and extort without encrypting anything. The patch had existed since June 17; the wave of extortion emails arrived a month later. Why your backups can't undo a theft, what the Accellion→MOVEit→Oracle EBS pattern teaches (2,700+ organizations in a single campaign), and the five things we would do this week.

SD-WAN multi-sede: cuándo compensa y cuándo sobra

SD-WAN yes, but not everywhere: when it pays off and when it's overkill

Gartner predicted that by 2026, 70% of enterprises would have SD-WAN. We deploy it — and even so, more than once we have recommended against it. What problem it actually solves, when it pays off (changing sites, two transports, suffering applications), when two lines and WireGuard do the job, and the costs that never show up in the demo: the forever license, the orchestrator as a dependency and the complexity that doesn't disappear — it relocates.

The hotel Wi-Fi works for someone else: DNS hijacked to steal Microsoft 365 accounts

Since June 2026 an active campaign has been compromising captive portals at hotels and conference centers, changing their DNS and redirecting guests to fake Microsoft 365 pages. The refined part: by abusing the device code flow they take your account without stealing your password, with MFA "satisfied". What is happening, why the padlock won't save you, and what we would do: from full-tunnel VPN to blocking the device code flow.

Colocation vs cloud público: la cuenta a cinco años, con el caso 37signals
8 min read

The cloud isn't expensive: it's expensive for the wrong workload. Colocation vs public cloud, with the math done

37signals was paying $3.2 million a year for cloud, bought $700,000 of servers and recouped them in the first year; in 2025 it announced moving its 18 PB out of S3. Meanwhile, worldwide cloud spending keeps growing at a 20% annual clip. Both things are true: the difference is who does the math. Which workloads overpay in the cloud, when the cloud still wins, and the five-year colocation math, line by line.

Una IA autónoma automatiza la post-explotación en un ataque real; la respuesta es detección 24/7
8 min read

The tireless intern now works for the other side: an autonomous AI is already automating real attacks

In an intrusion at Thailand's Ministry of Finance, the attacker left an open-source AI agent running unattended to automate the boring part of the attack: enumerate, escalate privileges, find the next step. It broke nothing new —it got in through default credentials and unpatched 2021 CVEs— but it did the dirty work faster and without rest. What actually changes is speed, and the only answer to speed is 24/7 detection and response.

Certighost (CVE-2026-54121): impersonar un Domain Controller vía AD CS

Certighost: any user could become your Domain Controller. The question isn't whether you patched, it's whether you've audited your AD CS

Certighost (CVE-2026-54121) let an unprivileged domain user impersonate a Domain Controller via Active Directory Certificate Services and take over the entire domain. Microsoft patched it on July 14; a working PoC has been public since July 24. The mechanism in one sentence, why AD CS is the escalation surface almost nobody audits, and the plan for today: patch, inventory your CAs, machine account quota to zero, and audit templates.

Microsoft is retiring SMS for MFA: in February 2027 Entra ID stops sending them. The strange part is that it lasted this long

On July 13 Microsoft announced that Entra ID will stop providing SMS and voice calls as an authentication method: passkeys by default from September 1 and full retirement on February 1, 2027, with no opt-out. Anyone insisting on SMS will have to contract and pay their own telecom provider. The full timeline, why SMS was never a serious second factor, and the plan we would apply to any tenant.
