Automation can’t fix broken security basics – Help Net Security

Posted by jpluimers on 2026/03/25

[WaybackSave/Archive] Automation can’t fix broken security basics – Help Net Security reveals nothing new: like in many places, automation isn’t the solution for bad processes or bad behaviour. Automation just assists getting things done (even in security), only marginally leading people to getting these things right in addition to done.

Leadership often focuses on broad resilience goals while the day-to-day work that supports them remains inconsistent and underfunded.

This is especially true when the day-to-day activities mainly consists clicking on links and other user-interface elements.

Yes, dark patterns are being used by adversaries, but a lot of day to day user experiences are based on dark patterns.

Improve those experiences by designing better processes amended by better automation, not the other way around.

Oh, and get your foundations right. For example by having processes in place that ease timely patching, even if that requires deployment on fridays.

Buddy (software) – Wikipedia

Posted by jpluimers on 2025/12/03

Interesting: Buddy (software) – Wikipedia

Buddy (also known as Buddy.Works) is a web-based and self-hosted continuous integration and delivery software for Git developers that can be used to buildtest and deploy web sites and applications with code from GitHubBitbucket and GitLab. It employs Docker containers with pre-installed languages and frameworks for builds, alongside DevOps, monitoring and notification actions.

On my list of things to try in case built-in GitGub and GitLab functionality does not suffice my needs any more.

I wonder how well it runs on ARM architecture.

Be inquisitive: a Thread by @cyb3rops on Thread Reader App – The act of hiding is often more suspicious than what’s being hidden.

Posted by jpluimers on 2025/11/19

[Wayback/Archive] Thread by @cyb3rops on Thread Reader App – Thread Reader App

If your agent gets flooded – detect the flooding.
If code gets obfuscated – detect the obfuscation.
If ETW gets silenced – detect the silence.
If the EDR gets killed – detect the killing.
If logs get cleared – detect the clearing.

The act of hiding is often more suspicious than what’s being hidden.

It’s like a surveillance camera going black or freezing.
That is the signal.
I’ve been doing this successfully for years.

I detect obfuscated crap all the time.
People ask, “What is it?”
I say, “No fucking clue. Could be:
– a Themida-packed sample with a Microsoft copyright,
– a UPX-packed ELF with a 1-char filename,
– a PowerShell script that looks like static noise, or
– a fake svchost.exe with no Microsoft copyright.”

I don’t need to know what it is.
It’s obviously shady.
That’s enough to detect it – and deal with it.
There’s a Chinese saying that fits perfectly: 欲蓋彌彰
The more you try to hide it, the more obvious it becomes.

Infinite loops and the True Meaning of DevOps (Forrest Brazeal on Twitter)

Posted by jpluimers on 2025/11/05

[Wayback/Archive] Forrest Brazeal on Twitter: “Multiple people on LinkedIn have commented on this to swear they’ve seen people DELIBERATELY SHIP INFINITE LOOPS to justify their infra footprint That, my friends, is the true meaning of DevOps”

which was sparked because of comments on his [Wayback/Archive] Forrest Brazeal on Twitter: “Not all “utilization” is created equal…” cartoon:

Kevlin Henney on “configuration is code” in his essay “Out of Control. An essay on paradigms, refactoring…”

Posted by jpluimers on 2025/07/31

For my link archive [Wayback/Archive] Out of Control. An essay on paradigms, refactoring… | by Kevlin Henney | Dec, 2020 | Medium.

Neither because Kevlin describes how to refactor a basic algorithm to convert Roman numerals into Hindu-Arabic numerals (in part by using the fact that an if statement can be considered a bounded case of a while loop), nor because he splits the resulting algorithm in coded data and coded statements, or because he mentions the [Wayback/Archive] Gilded Rose Kata but because well, you should just read it in full.

The Twelve-Factor App

Posted by jpluimers on 2024/11/21

Still relevant: [Wayback/Archive] The Twelve-Factor App and [Wayback/Archive] 12 Fractured Apps — Medium

Once Docker hit the scene the benefits of the 12 Factor App (12FA) really started to shine. For example, 12FA recommends that logging should be done to stdout and be treated as an event stream. Ever run the docker logs command? That’s 12FA in action!

Some lessons to learn from the CrowdStrike debacle

Posted by jpluimers on 2024/08/20

About a month from International CrowdStruck Day, just a few thoughts, more likely to follow:

  • How well does your infrastructure behave when none of your Windows machines can boot?
  • How well is your out-of-band management?
  • How well is your CMDB doing key management, for instance for BitLocker encryption?
  • Is checkbox compliance more important than a single point of failure?
  • Can you ensure all updates from your supply chain are staggered/staged/phased with a kill switch when things get out of hand?
  • Are the worst case scenarios in your disaster recovery plans really the worst?
  • Do you understand the human factor of large scale outages (both of the people that – often indirectly – triggered them – hello #HupOps – and the ones that cannot work because of them)?
  • Do you value your people – especially the ones that pulled you out of this situation – enough, and did you rename your Human Resource department into something that is more friendly to your people?
  • Do you realise this could have happened on any of the platforms you use, including Linux and MacOS?
  • If you were mentioned in the media by not recovering well, do you have any idea how much a target you will be from adversaries?
  • Did CrowdStrike finally show some real postmortem instead of the half-hearted communications they did mostly after the weekend following the debacle?
  • How does your organisation perform dates of critical files?
  • Would other platforms be less or more risky? If so: why?
  • Will eBPF solve most of this, or at least centralise the issues and what consequences would that have?

Ookla speedtest CLI for Windows has some undocumented arguments to accept license and GDPR

Posted by jpluimers on 2023/10/11

I had speedtest-cli running on MacOS and various Linux machines, but not yet on Windows (see for instance my post Ubuntu: Fixing the myserious “Failed to stop apt-daily.timer: Connection timed out”).

[Wayback/Archive] Install and Test Internet Speed with Speedtest CLI Command Line – NEXTOFWINDOWS.COM reminded me there is a Speedtest CLI for Windows download at at [Wayback/Archive] Speedtest CLI: Internet speed test for the command line, but I am a an automation/scripting/devops person, so luckily there are also [Wayback/Archive] Chocolatey Software | Speedtest by Ookla (don’t get [Wayback/Archive] Ookla.Speedtest download, as that is the GUI version).

Both the Chocolatey and winget packages are named the same, so that is quite confusing. This is how I have set them apart:

The CPU load average metric often is not a good one to alert on

Posted by jpluimers on 2023/04/20

Boy I wish threads with more than one person could be saved by the ThreadReaderApp.

Anyway:

[WayBack] Thread by @mipsytipsy: oh boy.. i was just idly musing over how the single most ubiquitous/useless metric is “CPU load average”, lol i wonder if you could use CPU…

oh boy.. i was just idly musing over how the single most ubiquitous/useless metric is “CPU load average”, lol

i wonder if you could use CPU load alerts to score how modern and powerful a team’s toolchain is, like a Waffle House Index for tooling. 🤔

 

…oh oh! but i was gonna say, this thread between @drk and @shelbyspees is a killer nanotutorial in how to ask better questions about your code — where to start, how to drill down and dig in, how to instrument, and how to approach such an open-ended exploratory jaunt. 👏🐝❤️

it’s a really good illustration of this thing we end up saying all the time, which is “don’t fear the future, it is simpler and clearer and *easier* here! the way you are doing it NOW is the hard way!” 😖

time for cpu load average to go the way of the PC LOAD LETTER …
