Centralita telefónica manual con hileras de interruptores etiquetados a mano: apagar uno era rápido; saber qué línea dejaba muda, no

The report says "zero impacts", and that does not mean nobody uses it

Baseline Security Mode puts twenty-one settings in the Microsoft 365 admin center that used to live only in PowerShell: switching off basic authentication, EWS, ActiveX, IDCRL, Publisher. Microsoft's guidance says to turn each one on when its impact report comes back at zero. The detail that changes the reading: the Office app settings are delivered through Cloud Policy, and Windows clients below version 2510 do not send the simulation mode telemetry that feeds that report. What each switch turns off, what actually breaks when you close EWS, and the order we do it in.

Cronómetro deportivo: los cinco días entre el aviso VMSA-2026-0006 y las primeras conexiones de vCenter comprometidos a la infraestructura del atacante

13 Aug 2026 9 min read

The vCenter advisory said there was no known exploitation. It held for five days

Broadcom published VMSA-2026-0006 on 29 July with no information suggesting exploitation, and that is how we quoted it here the next day. On 3 August the first compromised vCenters started connecting to attacker infrastructure, and on 12 August QUIRSO published the count: 361 victim IP addresses across 47 countries. What those numbers mean, what they do not, and the question that decides whether this concerns you: who can open a connection to your vCenter.

Torres de telecomunicaciones entre la niebla: la red móvil privada que comparten empresas que no se conocen

They crossed from a wind farm to a power plant turbine through the grid operator's private APN

On 8 August CERT Polska published its analysis of the 29 December 2025 attack on a Polish combined heat and power plant. The attacker got in through a FortiGate with no multi-factor authentication, hopped to a cellular router, crossed the distribution operator's private APN and put three families of Siemens PLCs into STOP mode. The report does not cite a single CVE in the whole chain: what it describes is a mobile network we all call private in which any device could talk to any other.

CVE-2026-9198 en Langflow entra en el catálogo KEV de CISA el 4 de agosto de 2026: la capa de IA y automatización autoalojada (Langflow, n8n, Open WebUI) tratada como producción

5 Aug 2026 5 min read

The AI pilot nobody switched off is already production

On 4 August, CISA added a 9.8 in Langflow to its exploited-vulnerabilities catalogue: one endpoint that hands superuser tokens to anyone who reaches the port, chained with another that runs whatever code you send it. The patch had been out for six weeks. It is not an isolated case: in Open WebUI the ENABLE_CODE_EXECUTION=false switch turned nothing off, and in n8n anyone who could edit a workflow could run commands on the host. Three products, the same starting assumption. What we do with the AI and automation layer, and when we recommend not self-hosting it at all.

Más de 700 organizaciones afectadas por el robo de tokens OAuth de una aplicación conectada, sin ninguna contraseña robada

2 Aug 2026 5 min read

The token that never asks for MFA: connected apps in your Microsoft 365

More than 700 organisations were potentially exposed in August 2025 without a single password being stolen: the attacker took the OAuth tokens of an application they had connected themselves. On 13 July 2026 Microsoft published the map of a full year of that technique: two attack chains and not one suspicious sign-in. The part that fails is not the login, it is consent: how to inventory the applications connected to your tenant with two Graph queries, what each button actually switches off, and why changing the consent setting revokes nothing already granted.

Secuestro de DNS en Wi-Fi de hoteles para robar cuentas de Microsoft 365

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.

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

25 Jul 2026 5 min read

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 retira el SMS como MFA en Entra ID: passkeys por defecto

Microsoft SMS MFA end of life: Entra ID stops sending texts in February 2027

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.

Zero-day CVE-2026-16232 · exposed management

24 Jul 2026 5 min read

The Check Point zero-day wasn't after your firewall: it was after its console

CVE-2026-16232: an authentication bypass in SmartConsole allowed logging into the server that governs all your Check Point gateways as an administrator, with no credentials. It was exploited before the patch existed and CISA gave three days to remediate. Why the management plane is a bigger prize than the firewall itself, and the checklist that applies even without Check Point.

22 days inside: the SonicWall SMA 1000 zero-days and why the perimeter VPN is no longer the defense — it's the target

Zero-days CVE-2026-15409 and CVE-2026-15410 were exploited from June 22, 22 days before the patch, with theft of credentials and MFA seeds. Why the VPN appliance is the perfect target and what to do beyond patching.
