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

27 Jul 2026 7 min read

"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 extorsiona sin cifrar: campaña contra PTC Windchill y FlexPLM

27 Jul 2026 7 min read

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

26 Jul 2026 5 min read

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.

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

26 Jul 2026 7 min read

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

26 Jul 2026 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

25 Jul 2026 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

25 Jul 2026 9 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

25 Jul 2026 7 min read

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.

Ceph: réplica 3 vs erasure coding, la cuenta completa

24 Jul 2026 9 min read

Erasure coding promises twice the space of 3-way replication in Ceph. The full math says otherwise

Same fault tolerance and twice the usable space: pitched like that, erasure coding sounds obvious. We run Ceph in production and our VMs are still on 3-way replication. The space math, the write math, the recovery math and the node math — and where we do use erasure coding.

Microsoft 365: caída del 23 de julio de 2026 y plan de continuidad

Microsoft 365 went down again: you can't DR your way out of Teams (but you can have a plan)

On July 23 a network configuration change left Teams, SharePoint and OneDrive limping for hours: the fifth major hyperscaler outage in nine months. When your entire office lives in a SaaS there is no replica to boot and no runbook that helps: the SLA is credits, not continuity. What we wouldn't do, and the two-page plan that actually works.

Zero-day CVE-2026-16232 · exposed management

24 Jul 2026 9 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.

SharePoint 2016/2019

SharePoint 2016 and 2019 just ran out of patches, and this time there's no extension you can pay for

On July 14 SharePoint Server 2016 and 2019 fell out of extended support, and Microsoft offers no ESU: there is no paid extension. A year ago ToolShell compromised over 400 organizations attacking on-prem SharePoint that was still receiving patches. The three real ways out, and the fourth one almost nobody offers you.

Your firewall can't stop a DDoS: the latest record hit 31.4 Tbps. Real mitigation happens upstream

In December 2025 the largest DDoS on record was mitigated: 31.4 Tbps, roughly 31,000 times the capacity of a 1 Gbps fibre. By the time that traffic reaches your firewall, the battle is already lost. What RTBH is, why a local blackhole won't save your link, and what to ask your provider.

Malware no longer fools you: it fools your AI. FakeGit and its 7,600 fake GitHub repositories

The FakeGit campaign seeded GitHub with 7,600 fake repositories; roughly 200 of them alone account for over 14 million malware downloads. The news isn't the volume: more than 800 posed as MCP servers and AI skills, and the assistants recommended them on their own. It has a name now: agentbaiting.

Romania's land registry

Wiped; saved by the out-of-reach copy

Romania's land registry was wiped, backups included. It was saved by the copy the attacker couldn't touch

On July 14 an attacker got into Romania's ANCPI with valid credentials, failed to extort the agency, and wiped the land registry database plus every backup within reach. A week with no property sales or mortgages nationwide. The difference between incident and catastrophe was one copy beyond his reach.
